Climate models are evolving, and are getting more accurate, but they are still incomplete. Our atmosphere is very complex, and there are factors that even current models don’t address, or address with an in-complete knowledge of the physical processes involved. This leads to inaccuracies that create uncertainty in the results of climatic projections. (more…)
Numerous plant species on a mountain in the southwestern U.S. are migrating to higher elevations as the climate gets warmer and drier, according to a new study.
After comparing the results of a recent survey of 27 plants found on Mount Lemmon, a 9,157-foot peak near Tucson, Ariz., with a similar survey conducted in (more…)
What has six-hundred tons of volcanic rocks sitting in a giant steel tub, thousands of gallons of water spouting from a network of pipes, and 1,800 sensors scattering three identical hillslopes collecting information? If you guessed the world’s only and largest manmade experimental watershed, then you’re correct! (more…)
A team of British and Australian scientists has discovered an important carbon sink from water drawn down from the surface of the Southern Ocean to the deep waters beneath. The Southern Ocean is an important carbon sink in the world — around 40% of the annual global CO2 emissions absorbed by the world’s oceans enter through this region. Reporting this week (more…)
Andrew Weaver is a notable Canadian climate scientist. He’s recently written a short book for the general reader to give an easily understandable account of the science of human-caused climate change, to explain its impacts and to suggest solutions. The book is published as one of the Rapid Reads series (more…)
Monks from the 1600s now have a hand predicting future climate change. No, this isn’t about Nostradamus. Rather, researchers from the University of Edinburgh are using monks’ diaries to reconstruct temperature records from the past to improve future predictions.
The researchers wanted to confirm climate (more…)
Research conducted by the University of Bristol, and the University of Leeds in the UK have demonstrated that our climate models may be underestimating the effects of CO2 on global temperatures.
than has previously been estimated, reports a new study published in Nature Geoscience this week.
The results show that components of the Earth’s climate system that vary over long timescales — such as land-ice and vegetation — have an important effect on this temperature sensitivity, but these factors are often neglected in current climate models.
