Remote areas in Canada’s Arctic region – once thought to be beyond the reach of human impact – are responding rapidly to warming global temperatures, the University of Toronto's Igor Lehnherr has found.

The Sahara Desert is Expanding, According to New UMD Study
The Sahara Desert has expanded by about 10 percent since 1920, according to a new study by University of Maryland scientists. The research is the first to assess century-scale changes to the boundaries of the world’s largest desert and suggests that other deserts could be expanding as well. The study was published online March 29, 2018, in the Journal of Climate.
Intensifying Tropical Storm Jelawat Evaluated by NASA's GPM Satellite
The Global Precipitation Measurement mission or GPM core observatory satellite flew almost directly above large intensifying tropical storm Jelawat and found strong storms generating very heavy rainfall,
GPM passed over the Northwestern Pacific Ocean and captured data on Jelawat on March 28, 2018 at 1:10 a.m. EDT (0510 UTC).

The Arctic Sea-Ice Loss and Winter Temperatures in Eurasia
The Arctic warming and the decline of the polar sea ice, do these phenomena have a connection to the cooling trends of winter in the Eurasia?
Ocean acidification: Herring could benefit from an altered food chain
As soon as they start life, it's all about survival for juvenile young fish. They must learn to catch prey and to escape enemies. Additionally, at this stage of their lives they are highly sensitive to environmental factors such as temperature, oxygen and the pH of the water. Exactly these factors are currently changing on a global scale: temperature is rising, the oxygen content of the ocean is decreasing and more and more carbon dioxide (CO2) from the atmosphere dissolves in the seawater, where it forms carbonic acid and lowers the pH level. But not only directly, also indirectly elevated CO2 affects the survival of fish larvae, because it can change their food supply.
