NASA's Aqua satellite passed over the Central Atlantic Ocean and looked at cloud top temperatures in Debby, revealing the storm had transitioned from subtropical to tropical.

Trying to tackle climate change by replacing forests with crops for bioenergy power stations that capture carbon dioxide (CO2) could instead increase the amount of CO2 in the atmosphere, scientists say.

Tropical Storm Ileana continued to move north along the coast of western Mexico on Aug. 7 but cloud tops warmed as a result of interaction with land and nearby Hurricane John. Infrared data from NASA's Aqua satellite provided forecasters with temperature data that showed cloud top temperatures in Ileana were strongest around its center.

The warming ocean may cause the larvae of bottom-dwelling snails to hatch earlier in the spring, when waves are larger, potentially impacting their ability to survive and serve as food for other sea creatures.

New research, led by former Carnegie postdoctoral fellow Summer Praetorius, shows that changes in the heat flow of the northern Pacific Ocean may have a larger effect on the Arctic climate than previously thought. The findings are published in the August 7, 2018, issue of Nature Communications.

It’s official: 2017 was the third-warmest year on record for the globe, behind 2016 (first) and 2015, according to the 28th annual State of the Climate report. The planet also experienced record-high greenhouse gas concentrations as well as rises in sea level.

When people think of the Arctic, snow, ice and polar bears come to mind. Trees? Not so much. At least not yet.

A new NASA-led study using data from the Arctic Boreal Vulnerability Experiment (ABoVE) shows that carbon in Alaska's North Slope tundra ecosystems spends about 13 percent less time locked in frozen soil than it did 40 years ago. In other words, the carbon cycle there is speeding up -- and is now at a pace more characteristic of a North American boreal forest than of the icy Arctic.

An infrared look by NASA's Terra satellite found powerful storms in the center of Tropical Storm Shanshan, the newest tropical storm in the Northwestern Pacific Ocean. Shanshan has triggered warnings in the Marianas Islands. 

Hurricane Hector has a small, tight center surrounded by strong storms. Infrared satellite imagery provides temperature data, and when NASA's Aqua satellite passed over Hector the coldest cloud tops circling the center were compact.

Canada’s first research vessel dedicated exclusively to historic Hudson Bay – a landmark for scientific research in Canada’s North – will leave port in Summerside, PEI this week to explore some of the most understudied regions of the Arctic.
