A week after Hurricane Maria rolled through Puerto Rico, the island faces a public health crisis with no power and a growing shortage of drinking water and food.

New technological interventions are needed to save coral reefs under climate change.

Tropical Storm Maria is now caught up in the Westerlies and is being affected by wind shear that is elongating the storm. Infrared imagery from NASA’s Aqua satellite revealed that Maria’s strongest storms were east of the tropical cyclone’s center because of westerly wind shear.

Currently, winter has still a firm grip on Antarctica. At this time of the year, the Weddell Sea usually is covered with a thick layer of sea ice. In spite of the icy temperatures in the region, satellite images depict a large ice-free area in the middle of the ice cover. The area of the hole in the ice is larger than The Netherlands and it fascinates climate and polar researchers worldwide. Scientists from the GEOMAR Helmholtz Centre for Ocean Research Kiel are closely monitoring the developments. “For us this ice-free area is an important new data point which we can use to validate our climate models. Its occurrence after several decades also confirms our previous calculations," says Dr. Torge Martin, meteorologist and climate modeler in the GEOMAR Research Division "Oceans Circulation and Climate Dynamics".

In a study that shows the importance of climate change on critical pollinators, North Carolina State University researchers found that earlier and longer flowering seasons can have poor effects on the bumble bees that rely on these flowers to live and thrive.

This past summer Canada has been plagued with huge forest fires that have spanned most of the provinces.  British Columbia has been particularly hard hit with large portions of the landscape being decimated by fire.  In these satellite images taken by the NASA'S Aqua satellite, both the natural color and false color burn scars of left by fires can be seen.  In the natural color image it is difficult to make out the burn scars.  The false color easily identifies areas where fire has left a scar showing a brownish-red color. Currently there are 745 wildfires larger than 0.01 hectares and all wildfires of note (active or out) in British Columbia as of today, Sept. 29. (Wildfire link updates daily).  NASA's Aqua satellite collected this natural-color image with the Moderate Resolution Imaging Spectroradiometer, MODIS, instrument on September 27, 2017. 

NASA and NOAA satellite imagery show Hurricane Lee has been on a weakening trend as wind shear is battering the storm. The National Hurricane Center expects Lee to weaken quickly and its remnants to bring gusty winds to Ireland and the United Kingdom over the weekend of Sept. 30 and Oct. 1.

Tropical forests have long been considered one of the world’s most important tools in combating climate change, their fast-growing trees and rich soils sucking millions of tons of carbon out of the atmosphere every year. But a new study says these forests have switched from being carbon sinks to sources of carbon, releasing an estimated 425 million tons of CO2 each year, more than the annual emissions from U.S. cars and trucks combined.

Researchers have observed and characterized a weather process that was not previously known to occur in Antarctica's coastal regions. It turns out that the katabatic winds that blow from the interior to the margins of the continent reduce the amount of precipitation (mainly snowfall) -- which is a key factor in the formation of the ice cap. By forming a very dry layer of air in the first kilometer or so of atmosphere, the winds turn the falling snowflakes during their fall directly from their solid state into water vapor in a process known as sublimation.

When a magnitude 9 earthquake shook the western Pacific Ocean floor and sent a tsunami crashing into Japan in 2011, millions of pieces of debris — from docks and fishing boats to plastic pollution — were swept out to sea. Now, a new studyfinds that nearly 300 species hitchhiked aboard that debris across the Pacific and were scattered along the west coast of North America.
