New studies in Science and Geophysical Research Letters (GRL) find that glaciers in the Amundsen Sea region of the great Antarctic ice sheet have begun the process of irreversible collapse. That by itself would raise sea levels 4 feet in the coming centuries.

The free pass that frackers and natural-gas handlers have gotten on their climate-changing methane emissions is really starting to stink to high hell. We told you in February about the results of a meta-analysis of 20 years worth of scientific studies, which concluded that the EPA underestimates the natural-gas industry’s climate impacts by 25 to 75 percent, due to methane leakage from its gas dril

Arguments that the climate is relatively insensitive to the increased greenhouse effect have become the last best chance for climate contrarians, but a new study from Texas A&M University hammers a big nail in the coffin of that argument.

A large section of the mighty West Antarctica ice sheet has begun falling apart and its continued melting now appears to be unstoppable, two groups of scientists reported on Monday. If the findings hold up, they suggest that the melting could destabilize neighboring parts of the ice sheet and a rise in sea level of 10 feet or more may be unavoidable in coming centuries.

The CNN left/right debate show Crossfire was off for a while last month, apparently because there's no way to "debate" the search for a missing plane. The show returned this week, and Tuesday's show (5/6/14)  illustrated another issue that should be considered beyond the realm of the "both sides" TV debate: climate change.

Yesterday, the Office of the President of the United States announced  an information campaign that will be ongoing to inform the U.S. public of the consequences of changing climate patterns and conditions in the U.S. The announcement coincided with the release of the Third National Climate Assessment of scientists in the U.S. You can read an announcement of all this here).

The National Climate Assessment is the definitive statement of current and future impacts of carbon pollution on the United States. And the picture it paints is stark: Inaction will devastate much of the arable land of the nation’s breadbasket — and ruin a livable climate for most Americans. “Americans face choices” explains the Congressionally-mandated report by 300 leading climate scientists and experts, which was reviewed by the National Academy of Sciences.

The unsettling story of how global warming helped fuel two record-breaking multi-billion dollar weather disasters thousands of kilometers apart this winter highlights just how unpredictable and dangerous our CO2 turbo-charged climate system is becoming. On the west coast, California is suffering its worst winter drought ever recorded. The failure of the rainy season left critical snowpack levels at just 30% of normal.

As carbon emissions concentrate in the atmosphere, the planet is burning up... and fast.

That is the well-known bottom line when it comes to human-caused global warming and climate change. 

Over the course of April, according to the world's premiere atmospheric monitoring station  Mauna Loa, Hawaii, which is run by the National Oceanic and Atmospheric Administration (NOAA), the concentration of carbon averaged more than 400 parts per million for the entire month for the first time in human history.

Last year, the Intergovernmental Panel on Climate Change started the publication of its 5th Assessment Report (or AR5), initially showing the work by the Working Group I, which deals with the physical basis of climate change. Now, the AR5 process continued with the publication of the “Summary for Policy Makers” by the Working Group II, concerning “impacts, adaptation and vulnerability.”
