We could say clouds are too complicated for climate science – and ignore them forever. We could also just try to incorporate them in the models. If you do, chance is you’ll find climate sensitivity is underestimated, a very interesting … Continue reading →
Over the last 40 years global air travel has almost increased eight fold: In 1974 air planes carried 421 million people globally. In 2014 this number has increased to 3,21 billion passengers – that’s a billion more in just five … Continue reading →
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.
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 →
