Global Warming "Hiatus" Never Happened: New Study

Data show no slowdown in global warming
A NOAA-led study refutes the much-publicized idea that there has been a recent slowdown or “hiatus” in the rate of global warming . The study finds that global warming during the last 15 years has progressed as fast or faster than during the latter half of the 20th century.

Antarctic Ice Shelf Faces Imminent Demise

Broken-up ice on the coast of Antarctica
The last remaining piece of Antarctica’s Larsen B Ice Shelf will likely disintegrate by the end of this decade, according to a new NASA-led study. The ice shelf, which partially collapsed in 2002, has existed for at least 10,000 years.

Modeling Summit Bridges Weather & Climate, Research & Operations

The U.S. Climate Modeling Summit brought together representatives from the Nation’s major research and operational climate modeling programs
A new white paper highlights outcomes from the first annual U.S. Climate Modeling Summit. The Summit brought together leadership from the country’s six premier climate modeling centers to strategize around priorities of national interest—from experimental efforts that move science forward to forecasts and projections that inform on-the-ground decisions.

From Thawing Permafrost, Slow but Steady Emissions Likely

Thawing permafrost releases greenhouse gases into the atmosphere
A new synthesis published in Nature suggests that thawing Arctic permafrost will release greenhouse gases gradually, rather than in a sudden "bomb". The gradual rate of these natural emissions may give society more time to adapt to their effects, but they remain a challenge for climate mitigation .

SMAP Into Action: Satellite to Measure Soil Moisture From Space

Artist's rendering of the SMAP satellite in orbit
Although the amount of moisture stored in soil is just a small fraction of Earth’s water, it plays a big role in the Earth system. NASA’s Soil Moisture Active Passive (SMAP) satellite, launched into orbit this morning, will collect unprecedented measurements of soil moisture around the globe.

IPCC Confirms: Climate Change is an Urgent Threat, Solutions Exist

A coastal wind farm
The Intergovernmental Panel on Climate Change (IPCC) released its Synthesis Report on Sunday, confirming that warming in the climate system is unequivocal and, if left unaddressed, will increase the likelihood of pervasive, irreversible damage to the environment and society. However, options to limit climate change and adapt to its impacts are available.
