The rainfall over the Yangtze River valley in the summer of 2016 was much weaker than that in 1998, despite the intensity of the 2016 El Nino having been as strong as that in 1998. A group of scientists from the Institute of Atmospheric Physics, Chinese Academy of Sciences, have now revealed the remarkable role played by the mid-latitude circulation in this surprising feature.
Sea Surface Temperature forcing can explain about 2/3 heat wave variability and the other 1/3 comes from atmospheric internal variability during 1979-2008.
An ongoing research project aims to identify and explain teleconnections and future changes in the East Asian Winter Monsoon under Arctic Amplification. This integral study would be beneficial for policymakers in evaluating the risk of cold extremes in East Asia, and will be of great importance for the socioeconomic development of this densely populated region.
New research out of the University of B.C. has uncovered a direct link between changes in the earth's crust three billion years ago and the introduction of free oxygen to the atmosphere. Without these changes, oxygen could have been suppressed in earth's crust forever, so the findings help explain the emergence of life on our planet.
Significant emission reductions are required if we are to achieve one of the key goals of the Paris Agreement, and limit the increase in global average temperatures to 1.5°C; a new Oxford University partnership warns.
Evidence of wildfires dating back 20,000 years was recently discovered in the Massif du Queyras, in the heart of the French Alps, 2,240 metres above sea level. The news comes in a joint Canada-France study published in New Phytologist. This discovery echoes the recent wildfires in the Arctic tundra, where [the presence of] trees have become increasingly common.
Conservation initiatives led by local and indigenous groups can be just as effective as schemes led by government, according to new research. In some cases in the Amazon rainforest, grassroots initiatives can be even more effective at protecting this vital ecosystem.
Southern cities such as Houston and Tampa -- which faced the wrath of hurricanes Harvey and Irma, respectively -- may not be the only urban environments vulnerable to extreme weather. Northern cities also face the potential for flooding as global temperatures continue to warm.
Environmental researchers have uncovered a wealth of information about a unique part of Australia that offers never-before-seen insights into climate change since the last ice age.
Global warming could reduce coffee growing areas in Latin America -- the world's largest coffee-producing region -- by as much as 88 percent by 2050. That's a key takeaway of the first major study of climate change's projected impact on coffee and bees, which help coffee to grow. The findings appear in PNAS. The research forecasts greater losses than previous global assessments, with the largest losses projected in Nicaragua, Honduras and Venezuela.
