On Monday, President Donald Trump said “we’re not backing down” on his intent to propose steel and aluminum tariffs that some legislators and analysts worry could have a negative effect on the U.S. energy industry and undercut the president’s goal of “energy dominance.”
Trump shared his desire for the tariffs—25 percent on steel imports and 10 percent on aluminum imports—last week. On Wednesday, White House press secretary Sarah Huckabee Sanders said that countries may be exempted on a “case-by-case basis” from the tariffs and that the president will make an announcement on the tariff issue by the week’s end.
Energy industry groups say that the plan to put a 25 percent tariff on overseas steel could a have a detrimental impact on the U.S. oil and gas industry and could be a double blow for the solar power industry, which is navigating new solar tariffs that went into effect last month. The groups contend that the steel tariff would raise costs for oil and gas pipelines and for solar power arrays, which would also face increased costs from Trump’s anticipated tariff on aluminum imports.
The 25 percent steel tariff could add as much as 2 cents a watt to the cost of a utility-scale solar project, according to the Solar Energy Industries Association. Additional price increases on steel and on aluminum, which are used in ground-mount and rooftop solar racking systems, could slow U.S. solar deployments already decreased by the solar tariff.
In the oil and gas industry, the 25 percent steel tariff could have an impact on pipelines. A study commissioned by oil and gas groups and released last year showed that a 25 percent price hike means an additional $76 million in costs for a traditional 280-mile pipeline and more than $300 million for a major project like the Keystone XL or Dakota Access pipelines.
Rules Governing Pollution from Oil and Gas Operations Under Microscope
The U.S. Environmental Protection Agency (EPA) announced amendments to two provisions of the New Source Performance Standards for the oil and natural gas industry. The 2016 standards aim to reduce the amount of methane and volatile organic compounds from oil and gas drilling.
One of EPA’s amendments would require that oil and gas operators repair leaking components during unplanned or emergency shutdowns and would impose monitoring requirements for wells on Alaska’s North Slope.
EPA said the changes were necessary because under the current requirements, repairs conducted during unscheduled or emergency shutdowns “could lead to unintended negative consequences both at well sites and compressor stations, including emissions that are higher than emissions that would occur if the leaks were repaired during a scheduled shutdown.”
The changes “provide regulatory certainty to one of the largest sectors of the American economy and avoid unnecessary compliance costs to both covered entities and the states,” said EPA Assistant Administrator for Air and Radiation Bill Wehrum, noting that the amendments are expected to save electric utilities $100 million per year in compliance costs and that they could help oil and gas operators reap $16 million in benefits by 2035.
Environmental advocates, meanwhile, expressed concerns that the changes could lead to dirtier air and water and reduce or remove consequences for large-scale polluters.
As Bloomberg Gets UN Climate Envoy Job, Study Pushes Emissions Trading
Former New York Mayor Michael Bloomberg was named U.N. special envoy for climate action on Monday. In his new role, Bloomberg will support a 2019 U.N. Climate Summit and mobilize more ambitious action to implement the 2015 Paris Agreement, which aims to limit global warming to well below 2 degrees Celsius above pre-industrial levels and to pursue efforts to limit that increase to 1.5 degrees Celsius.
“Around the world, bottom-up solutions are leading the fight against climate change,” Bloomberg said in a Twitter post. “As the new @UN Special Envoy for Climate Action, I’ll work with state and non-state actors to help implement policies that reduce emissions & build resilience.”
Three researchers wrote in the journal Science that allowing countries to satisfy their climate commitments by trading credits could bring down implementation costs.
“Linkage is important, in part, because it can reduce the costs of achieving a given emissions-reduction objective,” the authors write. “Lower costs, in turn, may contribute politically to embracing more ambitious objectives. In a world where the marginal cost of abatement (that is, the cost to reduce an additional ton of emissions) varies widely, linkage improves overall cost-effectiveness by allowing jurisdictions to finance reductions in other jurisdictions with relatively lower costs while allowing the former jurisdictions to count the emission reductions toward targets set in their NDCs [nationally determined contributions].”

As part of the Bipartisan Budget Act of 2018, Congress gave a boost to carbon capture—a method for diverting emissions from crude production and coal- and gas-fired power plants—through the so-called 45Q tax credit. For every qualifying project, the boosted 45Q doubles a pre-existing tax credit to $50 per ton of carbon dioxide buried in underground storage and to $35 per ton that is used in a consumer product or to stimulate oil recovery.
“The act also expands the ‘EOR’ [enhanced oil recovery] credit to carbon oxides used for other industrial purposes, changes the definition of the entities to whom the credit applies, and sets capture thresholds for small facilities, electric generating facilities, and direct air capture facilities,” write Frederick R. Eames and David S. Lowman Jr. in Lexology.
Many see the potential for this credit to spur a renewed look at projects with carbon capture and storage and re-enliven policies around it.
“Now, with [the tax credit], the economics are looking very attractive,” said Roger Ballentine, a consultant and board member of 8 Rivers Capital, which is financing NET Power, a carbon capture project near Houston. “People are asking, should I do this. Before, those conversations weren’t even happening. Any major project like this will be a challenge. But the business case gets that much better with [the tax credit]. Once there is a business case, that’s why they happen.”
The nudge from the tax credit could help the technology to be more profitable.
“The reality of any technology development, particularly in the energy space, is it’s very difficult to move technologies into the marketplace without some sort of push,” said Walker Dimmig, spokesperson for NET Power. “The energy marketplace is incredibly competitive.”
Court Orders Enforcement of Methane Leak Rule
Last week, U.S. District Judge William Orrick issued a preliminary injunction blocking the Trump administration’s attempt to delay an Obama-era Bureau of Land Management (BLM) rule that sought to reduce venting, flaring and leakage of methane gas on public and tribal lands. The U.S. District Court for the Northern District of California ruled that BLM did not justify its decision to delay core provisions of its 2016 Methane and Waste Prevention Rule by one year.
“The BLM’s reasoning behind the Suspension Rule is untethered to evidence contradicting the reasons for implementing the Waste Prevention Rule, and so plaintiffs are likely to prevail on the merits,” Orrick wrote. “They have shown irreparable injury caused by the waste of publicly owned natural gas, increased air pollution and associated health impacts, and exacerbated climate impacts.”
In the lawsuit brought by environmental groups and two states—California and New Mexico—Orrick also denied a request to move the case to Wyoming where a similar case is pending.
The ruling was only on the BLM’s proposed one-year delay. It does not directly affect the BLM’s proposed repeal of several methane rule provisions announced earlier this month. That proposal removes at least seven elements introduced under Obama’s rule, including creation of waste minimization plans by companies and emissions reduction standards for well completion.
In announcing the changes to that portion of the rule, the BLM said that many of the former requirements were duplicative of state laws or had a higher cost or lower benefit than previously estimated. Once the BLM proposed repeal is published in the Federal Register, a 60-day public comment period will begin.
Reports Indicate Growth in Renewables in Cities
Worldwide, 101 cities are getting at least 70 percent of their total electricity supply from renewable energy—more than double the number since the 2015 signing of the Paris Agreement according to the Carbon Disclosure Project, which tracks climate-related commitments by corporations and governments.
The London-based Carbon Disclosure Project attributes the increase to the growing number of cities reporting to it (currently 570) and to a global shift to renewable energy. It reports that cities are investing $2.3 billion in 150 clean energy development projects and $52 billion in low-carbon urban infrastructure projects such as energy efficiency upgrades, electric transport networks and smart city programs.
“Cities are responsible for 70 percent of energy-related CO2 [carbon dioxide] emissions and there is immense potential for them to lead on building a sustainable economy,” said Kyra Appleby, director of cities at the Carbon Disclosure Project.
Notably, more than 40 of the cities identified in the report are powered entirely by renewables, including Burlington, Vermont, which gets its electricity from wind, solar, hydro and biomass. Although only a few of the 100-plus U.S. cities that report their energy mix to the project have achieved 70 percent or greater renewables generation, another 58 U.S. cities, including Atlanta and San Diego, are planning to hit the 100 percent renewables target within 20 years.
Meanwhile, two new studies shed light on renewables potential and actual deployment in the United States.
In one, scientists at the University of California at Irvine, the California Institute of Technology, and the Carnegie Institution for Science revealed that the country could reliably meet about 80 percent of its electricity demand with solar and wind power generation “by building either a continental-scale transmission network or facilities that could store 12 hours’ worth of the nation’s electricity demand.” Both options would entail huge—but not inconceivable—investments, they said.
A study by Southern Alliance for Clean Energy revealed that solar deployment is growing in some southern states, including North Carolina, where the solar market, one of the nation’s largest, is driven by favorable implementation of federal laws requiring renewable energy procurement, a state tax credit, and a renewable energy mandate. South Carolina, Florida, and Georgia are also emerging as significant state markets.
Globally, falling costs are playing a role in renewables uptake. According to data released by the World Economic Forum, unsubsidized renewables were the cheapest source of electricity in 30 countries in 2017, and they are expected to be consistently more cost effective than fossil fuels globally by 2020.

The Trump administration announced Monday that it will begin imposing a 30 percent tariff on solar cells and modules imported into the United States. The tariff will decline annually over a four-year period—reaching 15 percent in year four—and the first 2.5 gigawatts of imported solar cells will be exempt from the safeguard tariff in each of those four years.
The U.S. has the world’s fourth-largest solar capacity after China, Japan and Germany. The Office of the U.S. Trade Representative (USTR) said the tariff, which is opposed by most of the renewable energy industry, is necessary to prevent unfair practices by overseas manufacturers, mainly in Asia.
“From 2012 to 2016, the volume of solar generation capacity installed annually in the United States more than tripled, spurred on by artificially low-priced solar cells and modules from China,” the USTR said in a fact sheet announcing the Trump administration’s decision. “China’s industrial planning has included a focus on increasing Chinese capacity and production of solar cells and modules, using state incentives, subsidies, and tariffs to dominate the global supply chain.”
The tariff comes in response to petitions from two American manufacturers who complained for years that rising imports were eating into their sales. The International Trade Commission (ITC), in September, voted in favor of imposing a tariff. Monday’s announcement is similar to one recommended by the ITC late last year.
More than 80 percent of U.S. solar installations use imported panels, many of which come from China. However, China is not the only country that could be affected by the decision. Countries like South Korea now account for many of U.S. solar imports, which means they could face job losses and other hardships as a result of the tariffs.
Although imposing tariffs could create as many as 6,400 solar manufacturing positions, overall industry job losses could exceed those gains, an independent analysis by Bloomberg New Energy Finance performed for Utility Dive found. The Solar Energy Industries Association said 23,000 jobs would be lost in 2018, noting that most solar manufacturing in the U.S. involves making parts for cheaper imported panels.
Homeowner installation costs are expected to go up about 4 percent and utility-scale installation costs could go up about 10 percent, according to ClearView Energy Partners.
Before the tariff announcement, the U.S. Energy Information Administration estimated that total U.S. small-scale solar capacity was 16 gigawatts (GW) at the end of 2017 and projected it to grow to 19 GW by the end of 2018. It estimated that U.S. large-scale solar capacity totaled 27 GW at the end of 2017 and projected it to rise to 30 GW by the end of 2018.
Studies Examine Continuing Warming Trend
According to an analysis released last week by the National Aeronautics and Space Administration (NASA), 2017 was the second warmest year in 123 years of record-keeping. Using a different methodology, the National Oceanic and Atmospheric Administration (NOAA) had earlier put 2017 as the third warmest year. In either case, it was the 21st consecutive year in which the annual average temperature exceeded the 20th century average of 13.9 degrees Celsius (57 degrees Fahrenheit) and the third consecutive year that every state across the contiguous U.S. and Alaska experienced above-average annual temperatures. Notably, it was also the warmest year on record without the warming influence of El Niño, which contributed to the heat of the warmest year, 2016.
Gavin Schmidt, director of NASA’s Goddard Institute for Space Studies, said there’s little doubt about the source of the multi-decadal warming.
“Basically all of the warming in the last 60 years is attributable to human activities, and carbon dioxide emissions are the No. 1 component of that,” Schmidt said.
According to NOAA’s annual global climate report, worldwide, temperatures in 2017 were 0.8 degrees Celsius (1.5 degrees Fahrenheit) above the 20th century average, and ocean temperatures experienced their third-warmest year on record.
In Poll, Mayors Acknowledge Threat of Climate Change
Two-thirds of mayors said that cities should take action on climate change, even if doing so requires financial costs, according to an annual poll by Boston University.
“As the widening wealth gap, rising cost of housing and other economic challenges dominate the discourse in Washington, D.C. and across the country, the 2017 Menino Survey of Mayors provides invaluable insights into some of the most complex issues facing our nation’s mayors,” said Bob Annibale, Global Director of Citi Community Development and Inclusive Finance. “This year’s survey confirms yet again that our nation’s mayors are leading the way—prioritizing issues within and beyond their municipal borders, such as affordable housing and climate change, with innovative approaches that affect positive change for their constituents.”
Those polled cited a range of top climate and sustainability issues, including reducing the number of vehicles on the road (36 percent), upgrading city buildings and vehicles (31 percent), and sourcing greener energy (27 percent). Increasing residential density and updating building codes were also considered integral parts of any serious effort to address climate change, but when it came to the private sector, respondents pushed back on the need to institute new costly regulations.

Climate change has entered a new phase, said the United Nations World Meteorological Organization (WMO) on Monday. The WMO reported that concentrations of carbon dioxide (CO2) “surged again to new records in 2016,” and it predicted that the annual average for CO2 would remain above 400 parts per million (ppm), 44 percent higher than before the Industrial Revolution, for generations.
The 400 ppm threshold, a symbolic red line in the methodical march of greenhouse gas concentrations, was continuously breached for the first time in 2015—a rise driven largely by fossil fuel emissions and aided by a strong El Niño, which “triggered droughts in tropical regions and reduced the capacity of sinks like forests, vegetation and the oceans to absorb CO2,” the WMO said. Last year’s jump in carbon dioxide was the largest annual increase on record (subscription).
“The year 2015 ushered in a new era of optimism and climate action with the Paris climate change agreement,” said WMO Secretary-General Petteri Taalas. “But it will also make history as marking a new era of climate change reality with record high greenhouse gas concentrations.” “The El Niño event has disappeared. Climate change has not . . . Without tackling carbon dioxide emissions, we cannot tackle climate change and keep temperature increases to below 2 degrees Celsius above the pre-industrial era. It is therefore of the utmost importance that the Paris Agreement does indeed enter into force well ahead of schedule on 4 November and that we fast-track its implementation.”
Taalas added that improvements in the climate will be seen by 2060 if countries begin to lower their carbon dioxide emissions now.
Between 1990 and 2015, Earth experienced a 37 percent increase in radiative forcing—the warming effect on the climate—because of greenhouse gases from industrial, agricultural, and domestic activities, according to the WMO.
WMO’s announcement comes within a week of the National Aeronautics and Space Administration’s report that found September was the 11th consecutive month to set record high temperatures.
Study: Glacier Melt in Antarctica Could Help Predict Global Sea Level Rise
A number of research studies have suggested Antarctica’s ice is melting faster than previously thought, but two new studies may help better predict future Antarctica ice loss and global sea level rise. The studies examined the Pope, Kohler, and Smith glaciers—part of the Dotson and Crosson ice shelves—in West Antarctica.
“Our primary question is how the Amundsen Sea sector of West Antarctica will contribute to sea level rise in the future, particularly following our observations of massive changes in the area over the last two decades,” said University of California Irvine’s Bernd Scheuchl, lead author on the first of the two studies published in the journal Geophysical Research Letters. “Using satellite data, we continue to measure the evolution of the grounding line of these glaciers, which helps us determine their stability and how much mass the glacier is gaining or losing. Our results show that the observed glaciers continue to lose mass and thus contribute to global sea level rise.”
A second study published Tuesday in the journal Nature Communications found that a significant portion of Antarctica is subject to “intense unbalanced melting” revealing high rates of ice loss from glaciers’ undersides. It also blames receding glacial grounding lines for the ice loss—spurred by an influx of warm ocean water beneath the ice shelves.
The glacier that saw the most melt, the study says, was Smith. It lost about 1,000 feet of ice between 2002 and 2009, which authors think is “a strong piece of evidence” that these glaciers, along with the larger Amundsen region, were subjected to a large influx of warm ocean water during that period.
“If I had been using data from only one instrument, I wouldn’t have believed what I was looking at, because the thinning was so large,” said author Ala Khazendar, a researcher at NASA’s Jet Propulsion Laboratory, noting how the work shows how important it is to understand both the ocean circulation and seabed topography when determining future melt and sea level rise.
IEA: Significant Renewables Growth Expected by 2021
The renewable energy market is growing around the world, according to a study by the International Energy Agency (IEA). IEA raised its estimate of the amount of renewable energy on power grids 13 percent from its 2015 forecast. It forecasts a 825 gigawatt boost in capacity by 2021 (a 42 percent increase from today).
“We are witnessing a transformation of global power markets led by renewables and, as is the case with other fields, the center of gravity for renewable growth is moving to emerging markets,” said IEA Executive Director Fatih Birol.
The growth will mostly be driven by four countries: China, the U.S., India and Mexico. China is the leader.
“About half a million solar panels were installed every day around the world last year,” according to the report. “In China, which accounted for about half the wind additions and 40 percent of all renewable capacity increases, two wind turbines were installed every hour in 2015.”
In the United States over the next five years, renewable capacity is forecast to grow to 328.2 gigawatts from 221.1 gigawatts. During this period, solar PV is forecast to nearly triple—from 26.1 gigawatts to 77.5 gigawatts—and wind to grow nearly 71.5 percent.
“Renewables are and still remain dependent on policies … to create the right market rules and the right framework to attract investments,” said Paolo Frankl, head of the IEA’s renewable energy division.

The European Union (EU) is now the second body to submit an official climate target to the United Nations ahead of talks to reach a global climate agreement in Paris later this year. One of the world’s top emitters, the EU intends to reduce its emissions 40 percent (relative to 1990 levels) by 2030. This commitment is in addition to 2050 emissions reduction targets that a recent report published by the European Environment Agency claims may prove difficult to reach.
“The level of ambition of environmental policies currently in place to reduce environmental pressures may not enable Europe to achieve long-term environmental goals, such as the 2050 target of reducing greenhouse gas emissions by 80-95 percent,” the report said. It points to a 60 percent cut in transportation emissions toward which little progress has been made.
Another study that looks at commitments by all nations to curb the effects of climate change suggests that the U.N. goal of avoiding 2 degrees Celsius of warming by century’s end is unlikely to be met. According to the authors, to attain that goal, the agreement reached in Paris must not only be based on a shared commitment to creating “equitable access to sustainable development,” but must also be structured to facilitate dynamic and collaborative interactions between parties.
Negotiators aim to complete an agreement in Paris that would go into effect in 2020. All countries are due to announce their emissions reductions plans in June in Bonn.
Droughts in the Amazon Accelerating Climate Change
A severe drought in 2010 doubled the rate of tree mortality in the Amazon rainforest, causing a 1.4 billion ton loss in the forest’s uptake of carbon dioxide from the atmosphere. That’s the conclusion of a new study in Nature that finds droughts are causing the trees to exhale more carbon dioxide than they inhale. The authors say trees store a tenth less CO2 from the atmosphere during droughts, apparently because they are channeling their more limited energy reserves into growth.
“Here, we show for the first time that during severe drought, the rate at which they [tropical rainforests] ‘inhale’ carbon through photosynthesis can decrease,” said Christopher Doughty, one of the researchers. “This decreased uptake of carbon does not decrease growth rates but does mean an increase in tree deaths. As trees die and decompose, the concentrations of carbon dioxide in the atmosphere will increase, potentially speeding up climate change during tropical droughts.”
The study provides the first direct evidence of the rate at which individual trees in the Amazonian basin absorb carbon during a severe drought. An international research team compared the growth and photosynthesis rates of trees at 13 drought-affected and non-drought-affected rainforest plots across Brazil, Peru, and Bolivia. Researchers discovered that growth rates of the trees in the plots were unchanged but that photosynthesis rates on the six drought-affected plots slowed by some 10 percent over six months.
EIA Report Sees Growth in Wind, Solar
Electricity from renewable sources outpaced the growth of electricity from fossil fuel-fired plants in 2014, according to a new Energy Information Administration report. Though solar’s share of electricity production remained smaller than wind’s share, net generation of the former grew by more than 100 percent last year. Wind generation grew by 8 percent and is forecasted to grow by 16.1 percent this year and another 6.5 percent in 2016.
“Because wind is starting from a much larger base than solar, even though the growth rate is lower, the absolute amount of the increase in capacity is more than twice that of solar: 15 GW [gigawatts] of wind versus 6 GW of utility-scale solar between 2014 and 2016,” the EIA reports.
Ultimately, wind will see a net increase of 9.8 gigawatts—the most of any other power source in 2015. California and North Carolina will add the most utility-scale solar capacity to systems (73 percent combined).
“Given current growth rates, especially for solar and wind, it is quite possible that renewable energy sources will reach, or exceed, 14% of the nation’s electrical supply by the end of 2015,” noted Ken Bossong, executive director of the SUN DAY Campaign. “That is a level that EIA, only a few years ago, was forecasting would not be achieved until the year 2040.”

Negotiators have reached a deal at United Nations (UN) talks in Peru, setting the stage for a global climate pact in Paris in December 2015. The agreement, dubbed the Lima Call for Climate Action, for the first time in history commits every nation to reducing its rate of greenhouse gas emissions.
“As a text, it’s not perfect but it includes the positions of the parties,” said Peru environment minister and conference chair Manuel Pulgar-Vidal.
In addition to an “ambitious agreement” in 2015 that reflects each nation’s “differentiated responsibilities and respective capabilities,” the Lima document calls for submission of national pledges by the first quarter of 2015 by those states “ready to do so” and for setting of national targets that go beyond countries’ “current undertaking.”
Countries already imperiled by climate change, such as small island states, were promised a “loss and damage” program of financial aid.
Through Belgium’s pledge of $62 million, the UN Green Climate Fund met its initial target of $10 billion to aid developing countries in curbing carbon emissions.
“There is still considerable work to be done,” said Felipe Calderon, former president of Mexico and chairman of the Global Commission on the Economy and Climate, at the conclusion of the talks. “But I am encouraged that countries, all around the world, are beginning to see that it is in their economic interest to take action now.”
“We are happy that the final negotiated statement at COP20 in Lima has addressed the concerns of developing countries,” said India’s environment minister Prakash Javadekar. “It gives enough space for the developing world to grow and take appropriate nationally determined steps,” he said.
But the negotiations, at which U.S. Secretary of State John Kerry had made an impassioned plea for agreement, were considered a failure by those hoping for ambitious emissions reductions commitments.
“Against the backdrop of extreme weather in the Philippines and potentially the hottest year ever recorded, governments at the U.N. climate talks in Lima opted for a half-baked plan to cut emissions,” said Samantha Smith, leader of World Wildlife Fund’s global climate and energy initiative.
The remaining North-South divide over which countries should carry the majority of emissions-cutting costs—plus other thorny matters, such as how to finance poorer countries’ reductions and preparations for extreme climatic events—has increased the diplomatic heavy-lifting required to reach a final agreement in 2015.
“They [countries] got through Lima by largely skirting the issue for now,” said Elliot Diringer, executive vice president at the Center for Climate and Energy Solutions. “It’s hard to see that flying in Paris.”
Solar Net Metering Terms Set in South Carolina
An agreement filed in South Carolina outlines new terms for solar net metering in the state. The terms ensure homes, businesses, schools, and any nonprofit organizations using rooftop solar panels will be provided “one-to-one” retail credit (or full retail value) from the state’s utilities for each kilowatt hour generated back to the electric grid—making South Carolina the 44th state (subscription) to allow for full rate credit.
Referred to as net metering, this process was a key component of Act 236, a law passed in June, which made solar power more accessible in the state.
Upon gaining approval from the South Carolina Public Service Commission, the agreement—supported by utilities such as Duke Energy and environmental groups—will provide homeowners the opportunity to lease solar systems while allowing utility companies to recoup costs of offering service.
According to Dukes Scott, executive director of the South Carolina Office of Regulatory Staff, proposed rules from the Environmental Protection Agency’s Clean Power Plan on reducing carbon emissions will help determine the value or contribution of solar power.
Last Big Warmup May Offer Sneak Peek into Today’s Climate Change
Despite climate warming by five to eight degrees Celsius during the Paleocene-Eocene Thermal Maximum, nearly 55.5 million years ago, most of the species around that time survived. However, it took nearly 200,000 years for Earth to recover from that rise.

New research in the Bulletin of the American Meteorological Society finds that climate change influenced the majority of 16 extreme weather events in 2013. Specifically, it found evidence that climate change linked to human causes—particularly burning of fossil fuels—increased the odds of nine extreme events: amplifying temperature in China, Japan, Korea, Australia and Europe; intense rain in parts of the United States and India and severe droughts in New Zealand and California.
“It is not ever a single factor that is responsible for the extremes that we see; in many cases, there are multiple factors,” said Tom Karl, director of National Oceanic and Atmospheric Administration’s (NOAA’s) National Climatic Data Center, of the third NOAA-led annual report to make connections between human-caused climate change and individual extreme weather events.
Twenty groups of scientists conducted independent peer-reviewed studies on the same 16 extreme events occurring on four continents to arrive at their conclusions.
“There is great scientific value in having multiple studies analyze the same extreme event to determine the underlying factors that may have influenced it,” said Stephanie C. Herring of NOAA’s National Climatic Data Center and lead report editor. “Results from this report not only add to our body of knowledge about what drives extreme events, but what the odds are of these events happening again—and to what severity.”
Although the report concludes that the long durations of heat waves “are becoming increasingly likely” due to human-caused climate change, the effects of such change on other types of extremes—California’s drought and extreme rain in Colorado—are less clear.
“Temperature is much more continuous as opposed to precipitation, which is an on/off event,” said Karl. “If you have an on/off event, it makes the tools we have a little more difficult to use.”
Although the NOAA study reached mixed conclusions about the ongoing California drought’s connection to climate change, new research out of Stanford University is a bit more confident. The Stanford study found it is “very likely” that atmospheric conditions associated with the unprecedented drought in the state are linked to human-caused climate change.
“Our research finds that extreme atmospheric high pressure in this region—which is strongly linked to unusually low precipitation in California—is much more likely to occur today than prior to the human emission of greenhouse gases that began during the Industrial Revolution in the 1800s,” said Noah Diffenbaugh, a Stanford climate scientist.
According to the study, these high pressure ridges—currently parked over the Pacific Ocean—are now three times more likely to occur, and as long as high levels of greenhouse gases remain severe, drought will become more frequent.
Emissions from Industrial Facilities Rose Last Year
Reported greenhouse gas emissions from large industrial facilities were 0.6 percent—or roughly 20 million metric tons—higher in 2013 than in the year previous, according to new data from the U.S. Environmental Protection Agency (EPA), which linked the rise to greater coal use for power generation. A large majority of the increase, 13 million metric tons, was from the power sector alone—though overall emissions from power plants are down 9.8 percent since 2010. Reported emissions from the oil and natural gas sector declined 12 percent from 2011 levels, according to the report.
The news comes on the heels of an extension of the public comment period on EPA’s proposed Clean Power Plan, which aims to reduce greenhouse gas emissions from existing power plants, and of new comments by EPA Administrator Gina McCarthy concerning the proposal.
There will be “changes between proposal and final,” said McCarthy. “You may see adjustments in the state levels. You may see adjustments in the framework,” McCarthy noted, referring to the emissions reduction targets the EPA proposed for each state and to the formula used to calculate those targets. The changes could also include updates to the values for nuclear power and natural gas generation.
IEA Says Solar Could Become Dominate Energy Source by 2050
Solar could surpass fossil fuels as the largest source of electricity by mid-century, according to reports issued by the International Energy Agency (IEA). The reports suggests that together solar photovoltaic systems (PV) and concentrating solar power (CSP) could provide 27 percent of the world’s energy by 2050; fossil fuels would account for somewhere between 12 percent and 20 percent.
“The rapid cost decrease of photovoltaic modules and systems in the last few years has opened new perspectives for using solar energy as a major source of electricity in the coming years and decades,” said IEA Executive Director Maria van der Hoeven. “However, both technologies are very capital intensive: almost all expenditures are made upfront. Lowering the cost of capital is thus of primary importance for achieving the vision in these roadmaps.”
By 2050, the IEA said, PV will surge from today’s 150 gigawatts of installed capacity to 4,600 gigawatts, while CSP will increase from 4 gigawatts to 1,000 gigawatts (subscription). These projections are based on the IEA’s expectations that China and the United States will remain top installers for the foreseeable future and that PV will dominate up until 2030.
