The Congressional Review Act was used to repeal a rule that forced energy companies on the U.S. stock exchanges to disclose the royalties and other payments that oil, natural gas, coal and mineral companies make to governments in an effort to fight corruption in resource-rich countries. President Donald Trump signed legislation to scrap the rule, implemented by the Securities and Exchange Commission under the Dodd-Frank Wall Street Reform and Consumer Protection Act, on Tuesday.
“This is one of many,” Trump said after the signing of H.J. Res. 41. “We have many more left. And we’re bringing back jobs big league.”
The repeal of the Obama-era rule was made possible through the rarely used Congressional Review Act, which allows Congress a small window to scuttle regulations before they take effect with a simple majority vote and blocks regulators from writing similar rules in the future unless Congress authorizes them through subsequent legislation. Given the infrequency with which the Congressional Review Act has been used, however, legal uncertainty hangs over how the government approaches a statutorily required regulation that is overturned through the Congressional Review Act. Before Trump took office, the Congressional Review Act had been used only once, in 2001, to overturn a Clinton administration ergonomics rule.
So far, the House has moved to repeal eight other rules, including a rule restricting coal companies from dumping mining waste into streams and one curtailing methane waste from oil and gas drilling on public lands. The Senate could consider the latter, H. J. Res. 36, which would rescind the Bureau of Land Management’s Waste Prevention, Production Subject to Royalties, and Resource Conservation rule, this week. Also this week, Trump could sign a separate resolution scrapping the U.S. Department of the Interior’s Stream Protection Rule, enacted to protect 6,000 miles of streams and 52,000 acres of forests.
Meanwhile, Senate Majority Leader Mitch McConnell filed cloture Monday for six of Trump’s cabinet nominees, allowing them to come before the full Senate for a vote. Trump’s environment-focused nominees—Ryan Zinke (U.S. Department of the Interior) and Rick Perry (U.S. Department of Energy), are presently on hold. Some reports say Zinke’s confirmation may not be until March.
Although a Senate vote for Trump’s pick to lead the U.S. Environmental Protection Agency was expected this week, Senate Democrats requested Scott Pruitt’s vote be delayed due to a pending court case regarding e-mail records. There is no indication at this point that the vote will be delayed, however.
“These records are needed for the Senate to evaluate Mr. Pruitt’s suitability to serve in the position for which he has been nominated,” the Democrats wrote.
Sea Ice Continues to Shrink at Both Poles; Study Examines Method to Refreeze
Sea ice at the north and south poles continues to reach record low levels. In Antarctica, sea ice has shrunk to its lowest level since record keeping began in 1979—contracting to 2.287 million square kilometers. The average between 1981 and 2010 was more than 3 million square kilometers.
Sea ice in the Arctic is also tracking low—13.9 million square kilometers compared to the 30-year average of 15.2 million square kilometers.
“No one knows for sure what will happen, as there might be a rebounding from the very large decreases last year, or there might be a continuation of those decreases,” said Claire Parkinson, a NASA sea ice researcher. “Whichever way it turns out, the added information will probably help scientists to get a better handle on the likely causes.”
A new study published in Earth’s Future, the journal of the American Geophysical Union, suggests that it may be possible to refreeze ice in the Arctic, building back up record-low ice levels.
“This loss of sea ice represents one of the most severe positive feedbacks in the climate system, as sunlight that would otherwise be reflected by sea ice is absorbed by open ocean,” authors write. “It is unlikely that CO2 levels and mean temperatures can be decreased in time to prevent this loss, so restoring sea ice artificially is imperative.”
The authors examine a means for increasing sea ice production using wind power to pump water from the ocean and spray it on the surface during Arctic winters. Because the mean annual thickness of Arctic ice is approximately 1.5 meters, the authors say, this plan could increase the thickness of the ice by about 70 percent over the course of a winter—enough to counteract the 0.58 meters lost each year due to the changing climate.
“Thicker ice would mean longer-lasting ice. In turn, that would mean the danger of all sea ice disappearing from the Arctic in summer would be reduced significantly,” said Arizona State University’s Steven Desch, an author of the plan to use 10 million wind-powered pumps.
Human Activities Dwarf Natural Forces When It Comes to Climate Change Impacts
Two researchers who examined the Earth as a single complex system say they have captured in a one equation the impact of human activities. Those activities, specifically, the emission of greenhouse gases, are causing the climate to change 170 times faster than natural forces.
The study, published in the journal The Anthropocene Review, represents that exceptional rapid rate of change in an “Anthropocene equation.”
Explaining the equation in New Scientist, co-author Owen Gaffney of the University of Stockholm said it was developed “by homing in on the rate of change of Earth’s life support system . . . For four billion years the rate of change of the Earth system has been a complex function of astronomical and geophysical forces plus internal dynamics: Earth’s orbit around the sun, gravitational interactions with other planets, the sun’s heat output, colliding continents, volcanoes and evolution, among others.”
“In the equation, astronomical and geophysical forces tend to zero because of their slow nature or rarity, as do internal dynamics, for now,” Gaffney added. “All these forces still exert pressure, but currently on orders of magnitude less than human impact.”
Gaffney said that although complex interactions between the Earth’s core and the biosphere had rendered Earth relatively stable over millions of years, human societies would be unlikely to fare so well. The research concluded that failure to reduce anthropological climate change could “trigger societal collapse.”

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.

Antarctica is home to Earth’s largest ice mass, which unlike the Arctic remains frozen year round. But a new satellite-based study in the journal Geophysical Research Letters shows that atop the coastal Langhovde Glacier in East Antarctica’s Dronning Maud Land, large numbers of meltwater lakes have been forming.
The study suggests that the lakes—nearly 8,000 of them—appeared in the summer months between 2000 and 2013. Like lakes that have formed from the meltwater of ice sheets in areas such as Greenland, those in East Antarctica may affect rates and patterns of ice melt, ice flow and ice shelf disintegration.
“What we find is that the appearance of these lakes, unsurprisingly, is correlated directly with the air temperature in the region, and so the maximum number of lakes, and the total area of the lakes, as well as the depth of the lakes, all of these things peak when the air temperatures peak,” said Stewart Jamieson, a glaciologist at Durham University in the U.K. and one of the study’s authors.
The concern is that the lakes’ meltwater will drain into the underlying ice, causing the ice sheet to weaken. The long-term effects are unknown, the authors say.
“We do not think that the lakes on Langhovde Glacier are at present affecting the glacier, but it will be important to monitor these in the future to see how they evolve with surface air temperature changes,” said lead study author Emily Langley of Durham University in the U.K.
Natural Gas Emissions to Edge Out Coal Emissions This Year
In its latest Short-Term Energy Outlook, released last week, the U.S. Energy Information Administration (EIA) projects that for the first time since 1972 energy-associated carbon dioxide (CO2) emissions from natural gas will surpass those from coal. Although natural gas is less carbon-intensive than coal, its consumption has increased while coal consumption has decreased, leading to what the EIA expects will be 10 percent greater energy-related CO2 emissions from natural gas than from coal in 2016.
The EIA estimates that this year natural gas will fuel 34 percent of U.S. electricity generation, compared with 30 percent for coal. Last year, natural gas generated slightly less than 33 percent of electricity, and coal generated slightly more than 33 percent.
The EIA also noted that annual U.S. carbon intensity rates have been falling since 2005, in part because of increased consumption of low- or zero-carbon electricity from nuclear plants and renewables. Along with the decrease in coal consumption, the increase in non-fossil fuel consumption has reduced U.S. total carbon intensity from 60 MMmtCO2/quad Btu in 2005 to 54 MMmtCO2/quad Btu in 2015.
But the EIA’s emissions numbers do not reflect emissions of methane, a more potent greenhouse gas released by gas drilling and transport operations. The extent of methane emissions from oil and gas production and distribution is uncertain, complicating the climate impacts of switching from coal to gas. Once those emissions total more than 4 percent of total gas production, according to a study cited in Utility Dive, they begin to negate the climactic benefits of gas over coal.
Obama Uses Anniversary to Remind Country of Climate Change’s Threat to National Parks
As the United States marks the centennial of the National Park Service this week, its parks are being widely celebrated for their natural grandeur. But President Obama used the milestone as a reminder of the threat climate change poses to the parks in a video released Saturday.
“As president, I’m proud to have built upon America’s tradition of conservation. We’ve protected more than 265 million acres of public lands and waters—more than any administration in history,” said Obama.
“As we look ahead, the threat of climate change means that protecting our public lands and waters is more important than ever. Rising temperatures could mean no more glaciers in Glacier National Park. No more Joshua Trees in Joshua Tree National Park. Rising seas could destroy vital ecosystems in the Everglades, even threaten Ellis Island and the Statue of Liberty.”
The National Park Service warns that today’s “rapid climate change challenges national parks in ways we’ve never seen before. Glaciers are retreating at an unprecedented rate, increasingly destructive storms threaten cultural resources and park facilities, habitat is disrupted—the list goes on.”
How is the National Park Service planning for climate change? The Atlantic reports that although parks have been slow to adapt their management practices, they are taking steps to cut emissions and educate the public about climate change and its effects. It reports that the visitors’ center at California’s Pinnacles National Park runs on electricity from solar panels, passenger vehicles are banned in Zion National Park during the summer, and at Golden Gate National Recreation Area, several beach restoration projects are in the works due to erosion caused partly by sea-level rise.

Natural fluctuations specifically related to the Interdecadal Pacific Oscillation (IPO) are responsible for the increased growth of Antarctic sea ice, according to a new study in the journal Nature Geoscience. A negative shift in the IPO has caused cooler-than-average sea surface temperatures in the Eastern Pacific, allowing Antarctic sea ice to expand since 2000.
“The climate we experience during any given decade is some combination of naturally occurring variability and the planet’s response to increasing greenhouse gases,” said National Center for Atmospheric Research scientist Gerald Meehl, lead author of the study. “It’s never all one or the other, but the combination, that is important to understand.”
But what’s new in the latest study, writes Chris Mooney in The Washington Post, “is the suggestion that this negative IPO phase had consequences that stretched all the way to the Southern Ocean waters surrounding Antarctica—and that this, in turn, explains why most climate models didn’t predict the observed growth of Antarctic sea ice.”
Study researchers suspect that the IPO began switching to a positive phase in 2014 and that ice in the region may shrink in the next decade.
Study Points to Human Influence on Changes in Earth’s Biggest Body of Warm Water
A study in Science Advances has provided the first quantitative attribution of human influences on and natural contributions to warming of the Indo-Pacific warm pool (IPWP), Earth’s largest region of warm sea surface temperatures and one “fundamental to global atmospheric circulation and the hydrological cycle.”
To “fingerprint” anthropogenic forcings and natural causes of substantial IPWP warming and expansion, researchers at Pohang University of Science and Technology and their international colleagues paired observations with multiple climate model simulations integrated with and without human influences. They found that the IPWP had warmed by 0.3 Celsius and increased in size by about a third over the last 60 years primarily due to an increase in human-made greenhouse gases.
About 12 to 18 percent of the warming has been due to natural variability in the ocean, but the remaining portion is due to the greenhouse gas increase, according to study co-author Seung-Ki Min of Pohang University in South Korea.
“We have more energy available from the hotter ocean,” said Min. “That means the atmosphere will be enhanced to transport more energy from the tropical ocean to the high latitude zone.”
The findings indicate that future ocean warming could increase storm activity over East Asia and strengthen monsoons over South Asia.
“This wasn’t entirely surprising. We’ve long suspected climate change to be behind the changes, but no one had yet proven it,” said Evan Weller, lead author, noting that what was surprising is that the western portion of the pool, near India, is expanding more than the eastern part in the Pacific. “We don’t really know why. We’ll try to figure that out next.”
Report: United States Is Oil Reserves Leader
The United States holds the largest share of the world’s oil reserves—264 billion barrels to Russia’s 256 billion and Saudi Arabia’s 212 billion, according to Rystad Energy, a Norwegian industry research group that tracks proved and probable reserves, discoveries and undiscovered fields. More than 50 percent of remaining oil reserves, it claims, are unconventional shale oil. Texas alone holds more than 60 billion barrels of shale oil.
On the basis of a three-year analysis of 60,000 fields worldwide, the group estimates global reserves to be 2,092 billion barrels—roughly 70 times the current production rate of some 30 billion barrels of crude oil per year.
“This data confirms that there is a relatively limited amount of recoverable oil left on the planet,” the report says. “With the global car-park possibly doubling from 1 billion to 2 billion cars over the next 30 years, it becomes very clear that oil alone cannot satisfy the growing need for individual transport.”

The Great Barrier Reef, which last year narrowly avoided being put on the World Heritage endangered list, is experiencing its worst bleaching in recorded history. According to the Great Barrier Reef Marine Park Authority, overall mortality of the reef is 22 percent, but along Lizard Island, off far north Queensland, it’s 93 percent. Coral bleaching is also occurring along the Maldives, Thailand, and Christmas Island.
By year’s end, what the National Oceanic and Atmospheric Administration (NOAA) has designated the third global coral bleaching in less than two decades, and the longest and most severe so far, will have killed 12,000 square kilometers of reefs and affected more than a third of the world’s corals.
Satellite data produced for The Guardian by Mark Eakin, head of NOAA’s Coral Reef Watch, reveals the increasingly widespread impact of ocean temperature increases on the Great Barrier Reef, where bleaching is predicted to become an annual event by 2020.
“While there was a considerable amount of variability—from El Niños and other things—there was an obvious upward trend in the data,” Eakin said. “So you’re looking at the background warming, which is having a major effect on the corals.”
Although coral bleaching is thought to result largely from abnormally high sea temperatures that kill marine algae crucial for coral health, a study published Tuesday in Nature Communications and based on a three-year experiment on a coral reef in the Florida Keys nuances that understanding. Its authors say that widespread coral deaths observed in recent decades are being caused by a combination of multiple local stressors that become lethal in the presence of higher temperatures.
“This makes it clear there’s no single force that’s causing such widespread coral deaths,” said study co-author Rebecca Vega Thurber of Oregon State University. “Loss of fish that help remove algae, or the addition of excess nutrients like those in fertilizers, can cause algal growth on reefs. This changes the normal microbiota of corals to become more pathogenic, and all of these problems reach critical levels as ocean temperatures warm.”
United States and India Announce Climate and Energy Agreements
On Tuesday, following a meeting with President Obama partly focused on climate change and energy, Indian Prime Minister Narendra Modi said his country, the world’s third-largest greenhouse gases producer, would ratify the Paris Agreement this year. The action is considered a key step in cementing the deal, which goes into effect 30 days after 55 nations representing 55 percent of all greenhouse gas emissions ratify it. To date, countries representing approximately 50 percent of global emissions have announced that they will submit legal documentation of their compliance with the deal, under which more than 190 nations agreed to keep global warming to within 2 degrees Celsius of pre-industrial levels and to pursue efforts to limit warming to 1.5 Celsius.
“Both leaders feel as if the collaboration between the two leaders was an important element of actually getting Paris successfully negotiated last December,” said Brian Deese, President Obama’s top climate change advisor. “They will both clearly endorse the importance of promoting full implementation of the Paris agreement.”
President Obama indicated that the speed with which the agreement could be brought into force would depend in part on securing “the climate financing that’s necessary for India to be able to embark on a bold vision for solar energy and clean energy” laid out by Modi.
Among the other climate and energy agreements the countries announced was a joint effort to adopt, this year, an amendment to the Montreal Protocol on the use of hydrofluorocarbons (subscription). That amendment would increase financial support to the protocol’s multilateral fund and contain an “aggressive phasedown schedule” for the potent greenhouse gas.
According to a White House fact sheet, other joint efforts include a $40 million program to provide capital for solar projects and a $20 million clean energy finance initiative.
India also agreed to a low greenhouse gas emissions development strategy.
Ontario Unveils Climate Plan with Carbon Market Funding
Yesterday, Ontario announced its climate change action plan for reducing its greenhouse gas emissions by 80 percent from 1990 levels by 2050 and explained how that plan will work with its recently adopted carbon market, which it plans to link with that of California and Quebec in 2018.
According to the Ministry of the Environment and Climate Change, the action plan helps define how market proceeds will be spent. “By law, proceeds must be invested in projects and programs that help reduce greenhouse gas pollution,” said the ministry.
Most of the action plan’s C$8.3 billion in planned spending on combatting climate change will come from the annual C$1.9 billion that the government expects to raise by auctioning greenhouse gas emissions credits.
Canada’s four most populous provinces—representing 86 percent of Canadians—have, or are introducing carbon pricing, either through a carbon tax or a cap-and-trade program aimed at emissions reductions.
