A geoengineering solution to climate change could lead to significant rainfall reduction in Europe and North America, a team of European scientists concludes. The researchers studied how models of the Earth in a warm, CO2‑rich world respond to an artificial reduction in the amount of sunlight reaching the planet’s surface. The study is published today in Earth System Dynamics, an Open Access journal of the European Geosciences Union (EGU).
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.
Dispersing fine (sub-micron) light-scattering particles into the upper atmosphere could help to combat climate change, suggests a former UK government advisor and chemical engineer.
The long-necked plant-eating dinosaurs known as sauropods that lived about 150 million years ago appear to have been rather flatulent. New calculations put the combined methane production of the hulking beasts at 520 million tonnes (Tg). As a comparison the … Continue reading
A United States and Spanish research team has conducted a study into the most likely causes of climate change and came to a rather surprising conclusion. The most feasible manner of stopping climate change is halting economic growth. Or changing … Continue reading
It has been know for some time that large quantitites of methane lie hidden in reservoirs under the permafrost layers on the tundra and in clathrates on the continental shelve. It is neither a secret that those large quantities of … Continue reading
A large diversity of gasses in the atmosphere influence air quality, climate change and the recovery of the ozone layer. Measuring the concentrations of these gases in the atmosphere is quite straightforward. But pinpointing wether the gasses are a natural … Continue reading
In a study appearing this month in the journal Environmental Science and Technology, MIT researchers report that emissions from cars, trucks, planes and powerplants cause 13,000 premature deaths in the United Kingdom each year.
