In the midst of an unseasonably warm winter in the Pacific Northwest, a comparison of four publicly available climate projections has shown broad agreement that the region will become considerably warmer in the next century if greenhouse gas concentrations in the atmosphere rise to the highest levels projected in the the Intergovernmental Panel on Climate Change (IPCC) 'business-as-usual' scenario.
Peaking global CO2 emissions as soon as possible is crucial for limiting the risks of sea-level rise, even if global warming is limited to well below 2 degrees C. A study now published in the journal Nature Communications analyzes for the first time the sea-level legacy until 2300 within the constraints of the Paris Agreement.
After days of lingering off the west Kimberley coast of Western Australia as a slowly organizing low pressure area, Tropical Storm 10S has formed about 50 miles west of Broome, Australia.
NASA-NOAA's Suomi NPP satellite and the GPM core satellite passed over Tropical Cyclone Gita is it began weakening from vertical wind shear.
NASA's Aqua satellite passed over the Sulu Sea as Tropical Depression Sanba continued to weaken.
Tropical Cyclone Gita remained a powerful hurricane in the Southern Pacific Ocean when NASA-NOAA's Suomi NPP satellite passed overhead and captured a visible image of the storm.
Infrared data from NASA's Terra satellite found the area of strongest storms in weakening Tropical Cyclone Sanba when it was over the island of Palawan.
Tropical Cyclone Gita dropped a lot of rain as it strengthened into a major hurricane in the South Pacific Ocean. NASA's IMERG calculated totals based on satellite observations that revealed over a foot (305 mm) of rain had fallen in various areas.
Removing snow piled high in parking lots and along roadsides could soon be a far less tedious task. In a study appearing in ACS' journal Langmuir, scientists report that they have tested sunlight-absorbing thermal blankets capable of melting snow three times faster than it would on its own. They say the blankets could slash snow-removal costs and reduce the risk of environmental contamination caused by soot and other products used to melt the white stuff.
The Paris Agreement has aspirational goals of limiting temperature rise that won't be met by current commitments. That difference could make the world another degree warmer and considerably more prone to extreme weather.
