The largest volcanic eruption on Earth in the past millions of years took place in Indonesia 74,000 years ago and researchers from the Niels Bohr Institute can now link the colossal eruption with the global climate and the effects on early humans. The results are published in the scientific journal Climate of the Past.
The Climate Group called today for an “American Clean Revolution”, a massive scale-up of investment in cleantech and renewable energy, as a way to future-proof America’s infrastructure, avert catastrophic extreme weather events resulting from climate change, and boost the US economy.
The American Security Project released a new report analyzing the threats to national security both at home and abroad from climate change. As we are seeing by the events of this week, extreme weather – exacerbated by a changing climate – poses clear threats to the United States.
Using dogwood trees, scientists are gaining a better understanding of the role photosynthesis and respiration play in the atmospheric carbon dioxide cycle. Their findings will aid computer modelers in improving the accuracy of climate simulations.
Scientists and politicians disagree on climate change or the best ways to get America energy independent, but one thing is clear: The United States and the rest of the world need more energy. Scientists project that by 2050, the world will consume double the energy it does today.
As Hurricane Sandy begins to make its way up the East Coast, Duke Energy is making preparations for possible effects from the storm in Florida and the Carolinas.
The average area covered by the Antarctic ozone hole this year was the second smallest in the last 20 years, according to data from NASA and National Oceanic and Atmospheric Administration (NOAA) satellites. Scientists attribute the change to warmer temperatures in the Antarctic lower stratosphere.
UPM has received high scores for its climate change disclosure in the Nordic Carbon Disclosure Leadership Index. The index is compiled annually by the Carbon Disclosure Project (CDP). UPM was ranked in shared first place in the index with top scores: 98 points out of 100. UPM is featured in the index for the fourth consecutive year.
By using a new series of measurements of radiocarbon dates on seasonally laminated sediments from Lake Suigetsu in Japan, a more precise calibration of radiocarbon dating will be possible.
Reports of declining ice coverage and drowning polar bears in the Arctic illustrate dramatic ecosystem responses to global climate change in Earth’s polar regions. But in this first-ever account of a long-term project in the southern Caribbean, a Stony Brook professor and his colleagues report in this week’s Proceedings of the National Academy of Sciences U.S.A. that tropical ecosystems are also affected by global climatic trends - and with accompanying economic impacts.
