Basic physics tells us a warmer atmosphere can hold more moisture, and that, at some point, that moisture will condense and fall as rain. That’s why climate scientists are certain that global warming will lead to more extreme rainfall, as has already been documented in various parts of the world the past few decades.
A new study now helps quantify the impact of warming and also reveals regional patterns that will help people prepare. According to the researchers with MIT and the Swiss Federal Institute of Technology, the most extreme rain events in most regions of the world will increase in intensity by 3 to 15 percent, depending on region, for every degree Celsius that the planet warms.

No ice build-up in East Antarctica, new study says
Despite some suggestions that increased has bolstered the vast East Antarctic ice sheet, it appears the frozen continent is still shedding ice and has been a net contributor to sea level rise since at least 2003.
There’s been little doubt during the last decade that the West Antarctic Ice Sheet has been losing mass, but the picture has been much less clear to the east, where there’s enough ice to raise global sea level by some 50 meters. One study led by NASA researchers in 2015 suggested that this part of Antarctica was gaining so much mass that it compensated for the losses in the west.

European climate trackers say that April extended a stretch of exceptionally warm global weather going back to mid-2015. The warmth peaked in February 2016 at the height of Pacific Ocean El Niño, then gradually dropped off through June. But in July and August 2016 global temperatures surged upward once again and have stayed high since, according to the latest update from the Copernicus Climate Change Service.
Global warming seen as main threat to Arctic predators
Endangered Species Act protection for polar bears will remain in place following a U.S. Supreme Court decision late last week to reject an attempt by the fossil fuel industry to overturn the 2010 listing.
Loss of nitrogen-fixers would ripple through ocean ecosystems
In another sign that greenhouse gas emissions are going to fundamentally affect ecosystems in ways that we are just beginning to understand, a team of researchers has shown that bacteria in the ocean are losing their ability to fix nitrogen.
Many of the previously existing pages on climate science, greenhouse gases and global warming impacts are no longer available at the current EPA website.

Continuing its Orwellian policies of trying to create an alternative, fact-free reality, the Trump administration has started to remove climate-related information from the EPA website. As of Friday, April 28, a Google search for EPA climate information leads to a page-update notice, including a statement from a politically appointed spokesperson saying,” “We want to eliminate confusion by removing outdated language first and making room to discuss how we’re protecting the environment and human health by partnering with states and working within the law.” Continue reading “EPA removes web pages with climate change information”→
U.S. policy in turmoil as Bonn climate summit approaches
The future of the EPA’s Clean Power Plan is still up in the air, as the U.S. Court of Appeals for the DC Circuit has put a hold on legal proceeding pending the new administration’s review. The Clean Power Plan developed under the Obama administration would require modest cuts in greenhouse gas emissions from power plants with the goal of meeting global targets to cap global warming.
“This decision is disappointing but still leaves key issues about the future of the Clean Power Plan to be resolved,” said David Doniger, director of the Climate and Clean Air Program at the Natural Resources Defense Council. “We will continue to fight in the D.C. Circuit and in the court of public opinion to ensure that the government fulfills its legal obligation to protect the public from climate change.
