Before Tropical Storm Franklin made landfall in east-central Mexico, the storm was intensifying. Two NASA satellites provided a look at the storm's cloud heights and extent and rainfall within.

Portland State University researchers and the National Science Foundation (NSF) have publically released high-resolution maps of the McMurdo Dry Valleys, a globally unique Antarctic polar desert.

It is “extremely unlikely” 2014, 2015 and 2016 would have been the warmest consecutive years on record without the influence of human-caused climate change, according to the authors of a new study.

NASA's P-3 research plane begins flights this month through both clouds and smoke over the South Atlantic Ocean to understand how tiny airborne particles called aerosols change the properties of clouds and how they influence the amount of incoming sunlight the clouds reflect or absorb.

Drought-stricken areas anxiously await the arrival of rain. Full recovery of the ecosystem, however, can extend long past the first rain drops on thirsty ground.

According to a study published August 10 in Nature, the length of drought recovery depends on several factors, including the region of the world and the post-drought weather conditions. The authors, including William Anderegg of the University of Utah, warn that more frequent droughts in the future may not allow time for ecosystems to fully recover before the next drought hits.

University of Florida scientists discover cause of Atlantic coastline’s sea level rise hot spots.

July is the hallmark of summer in the United States. Long days, intense sun and high humidity typically make it the hottest month of the year. The heat can also trigger flash droughts, wildfires and summer storms. This July didn’t disappoint.

Here’s how July and the year to date fared in terms of the climate record. 

The amount of time it takes for an ecosystem to recover from a drought is an important measure of a drought’s severity. During the 20th century, the total area of land affected by drought increased, and longer recovery times became more common, according to new research published by Nature by a group of scientists including Carnegie’s Anna Michalak and Yuanyuan Fang.

Heatwaves amplified by high humidity can reach above 40°C and may occur as often as every two years, leading to serious risks for human health. If global temperatures rise with 4°C, a new super heatwave of 55°C can hit regularly many parts of the world, including Europe.

Perennial plants in the Midwest are well attuned to their surroundings. They hunker down all winter in a dormant state, just waiting for a sign that it’s safe to unfurl their first tender leaves or flower buds. For many plants, the cue is a sustained warming trend, but day length also factors into the dormancy equation.
