(Stockholm University) A new study shows that thick sea-ice can increase the sensitivity of Greenlandic fjords to climate warming. Understanding the factors that control how fast glaciers move, break up and deposit chunks of ice (icebergs) into the fjords – and eventually the sea – is vital for predicting how the Greenland ice sheet will change under a warming climate and for predicting global rates of sea-level rise.
Small asteroid 2021 GW4 will pass extremely close to Earth on Monday, April 12, 2021. It’ll pass just 12,313 miles (19,816 km) from Earth’s surface, or about 5% the Earth-moon distance. Amateur astronomers using telescopes can see it passing the galaxy Messier 95 on the night of Sunday, April 11.
In 2021, the likely peak morning for the Lyrids is Thursday morning, April 22. But the mornings around that date might be good, too. The moon is waxing – staying out longer after dark each night – so you’ll want to watch the time of moonset carefully.
(Institute of Atmospheric Physics, Chinese Academy of Sciences) A new study shows that human-induced emissions of greenhouse gases and aerosols in other regions of the world can also impact Central Asian precipitation and water resources by modulating the key atmospheric circulation.
Community Panel for Infrastructure Victoria on Transport Emissions. I was on this panel which had 211 Victorians (most age groups, Metro and Regional) and met online during late January to mid February 2021. The ‘Tackling Transport Emissions’ Community Panel successfully…
EDITOR: I’m a retired meteorologist with two degrees in atmospheric science. The great majority of the most qualified scientists in my field believe human-caused greenhouse gas emissions (and other short-sighted, careless actions like widespread deforestation) are responsible for a dangerous…
(KU Leuven) A new study shows that several disagreements between Ethiopia, Sudan and Egypt around Africa’s largest hydropower plant, the new Grand Ethiopian Renaissance Dam (GERD), could be alleviated by massively expanding solar and wind power across the region.
