Himalayan Glacier Melt Has Doubled Since 2000, Satellites Show
The researchers assembled the most detailed look to date at the last 40 years of Himalayan ice loss to date, combining contemporary satellite information with data from declassified U.S. spy satellites. They found that average ice-loss per year had doubled between the periods 1975 to 2000 and 2000 to 2016, and that the glaciers had lost more than 25 percent of their ice in the study period, The Guardian reported.
"This is the clearest picture yet of how fast Himalayan glaciers are melting since 1975, and why," research leader Joshua Maurer of Columbia University's Lamont-Doherty Earth observatory told The Guardian.

Melting since 2000 has been especially dramatic, The New York Times reported. The glaciers lost a foot and a half of ice every year since then, and have lost a total of eight billion tons of water each year recently, the equivalent of 3.2 million Olympic size swimming pools. Most of this melting was caused by the climate crisis. While researchers said some ice lost was due to soot from the burning of fossil fuels, most was due to warmer temperatures, which rose by higher rates on average between 2000 and 2016 across the more than 1,200 mile range.
Study co-author Joerg Schaefer, as at Columbia, told CNN that unless we act to reduce greenhouse gas emissions and cool the planet, we would see a "pretty devastating scenario for Himalayan glaciers."
University of Leeds glaciology specialist Duncan Quincey, who was not involved in the research, explained why.
"In the short-term, such rapid melt rates will mean summer floods become more frequent as river discharge is increased, but the long-term prospect is one of drought as the glacier reservoir becomes depleted," he told CNN.
Around 800 million people across Asia now rely on Himalayan glaciers for energy, agriculture and drinking water. But this study is part of a growing body of evidence showing how much climate change threatens these glaciers, and the communities they support. A February study found that even if world leaders managed to limit global temperature increase to the Paris agreement goal of 1.5 degrees Celsius above pre-industrial levels, one third of the ice in the Hindu Kush Himalaya (HKH) region would still melt by 2100. If temperatures hit two degrees, half of the ice would melt, and if temperatures rose to four or five degrees Celsius, two thirds would disappear.
University College London climate science Prof. Chris Rapley, who was not involved in the study, said ice loss was "already undermining the viability of small communities in the Himalayas as they suffer ever more serious water shortages." If it continued, it would displace a significant number of people.
"Better for all of us to accelerate to net zero as a matter of the highest priority," he told CNN.

Sen. Bernie Sanders on Tuesday was the lone progressive to vote against Tom Vilsack reprising his role as secretary of agriculture, citing concerns that progressive advocacy groups have been raising since even before President Joe Biden officially nominated the former Obama administration appointee.

Protecting forests is an essential strategy in the fight against climate change that has not received the attention it deserves. Trees capture and store massive amounts of carbon. And unlike some strategies for cooling the climate, they don't require costly and complicated technology.

There were many lessons to be learned from Texas' prolonged periods of lost power during its cold snap, which saw temperatures drop into the single digits. But one many people may not recognize is that electric vehicles, or EVs, can be part of a smart resiliency plan — not only in the case of outages triggered by the cold but in other scenarios caused by extreme weather events, from fire-related blackouts in California to hurricane-hit power losses in Puerto Rico.

Matthew Rader / CC BY-SA 4.0<p>Experts recognize that electric vehicles are a central climate solution for their role in reducing greenhouse gas emissions. But EVs are also essentially batteries on wheels. You can store energy in those batteries, and if EVs are equipped with something called <a href="https://en.wikipedia.org/wiki/Vehicle-to-grid" target="_blank">vehicle-to-grid</a> or vehicle-to-building technology, they can also be used to keep the lights on in emergencies. The technology allows the energy being stored in an EV battery to be pushed back into the grid or into buildings to provide power.</p><p>There are hurdles: The technology is still <a href="https://www.greenbiz.com/article/vehicle-grid-technology-revving" target="_blank">developing</a>, the vast majority of EVs currently on the road do not have this capability, and utilities would need regulatory approval before bringing it to scale. But done right it could be a great opportunity.</p><p>Electric car batteries can hold approximately <a href="https://www.wri.org/blog/2019/11/how-california-can-use-electric-vehicles-keep-lights" target="_blank" rel="noopener noreferrer">60 kilowatt hours (kWh)</a> of energy, enough to provide back-up power to an average U.S. household for two days. Larger electric vehicles like buses and trucks have even bigger batteries and can provide more power. The American company Proterra produces electric buses that can store <a href="https://www.proterra.com/press-release/proterra-launches-zx5-electric-bus/" target="_blank" rel="noopener noreferrer">up to 660 kWh of energy</a>.

Hermann / CC BY 2.0<p>If equipped with vehicle-to-grid or vehicle-to-building technology, those cars, buses and trucks could prove invaluable during future blackouts. People could rely on their cars to power their houses. Municipalities, transit agencies and school districts could send out their fleets to the areas most in need. We could power homes, shelters and emergency response centers — and could keep people warm, healthy and comfortable until power could be restored.</p><p>But to add this great resiliency tool to our arsenal in times of extreme weather, we must significantly increase the number of EVs on the road. In 2019 electric cars accounted for only about <a href="https://www.energy.gov/eere/vehicles/articles/fotw-1136-june-1-2020-plug-vehicle-sales-accounted-about-2-all-light-duty" target="_blank">2%</a> of all light-duty vehicle sales in the country. Electric buses and trucks are becoming more common in the United States, but still only represent a tiny fraction of the fleet. As it stands now, the EVs currently on the road, even if equipped with vehicle-to-grid technology, would do little to help a broad swath of the population in need of power.</p>

With lockdowns in place and budgets slashed due to the COVID-19 pandemic, many environmental protections vanished this past year, leaving some of the world's most vulnerable species and habitats at risk. But conservationists at the Borneo Orangutan Survival Foundation were faced with an entirely different threat.
Annapolis, Maryland, is suing 26 oil and gas companies for deceiving the public about their products' role in causing climate change. The city is among two dozen state and local governments to file such a lawsuit.
