In our series about the ‘Real’ Global Temperature Trend we’ve learned not to exaggerate the climate cooling potential of volcanoes. That is because many volcanoes are of the wrong type, lie on the wrong latitude – or, the vast majority, … Continue reading →
One idea for fighting global warming is to increase the amount of aerosols in the atmosphere, scattering incoming solar energy away from the Earth’s surface. But scientists theorize that this solar geoengineering could have a side effect of whitening the sky during the day. New research from Carnegie’s Ben Kravitz and Ken Caldeira indicates that blocking 2% of the sun’s light would make the sky three-to-five times brighter, as well as whiter. Their work is published June 1st in Geophysical Research Letters, a journal of the American Geophysical Union.
This year’s catastrophic drought in Kenya, Ethiopia, Djibouti and Somalia is thought to be an indirect consequence of the 2010-2011 La Niña. As part of ENSO cycles such droughts come and go – and have been typical for the region … Continue reading →
To notice something is going on with the world’s ice sheets, you could measure melting water runoff, glacier retreat or use satellites and GPS to measure ice volume decline. Just like measuring sea level rise and temperature this all adds … Continue reading →
