More extreme weather projected in the Amazon could have global climate consequences

EurekAlert: A new paper co-authored by WHRC scientists Philip Duffy and Paulo Brando evaluates the accuracy of current climate models and uses them to project future drought and wet periods in the Amazon. They conclude that the whole of the Amazon will confront more hydrological extremes, and that most of the region will experience much more frequent and extensive drought. These changes would have profound implications for forest structure, composition, biomass, and carbon emissions. According to Dr. Duffy,...

Marine analysis climate change impact suggests food chain collapse looms

Australian Broadcasting Corporation: A grim outlook for global fisheries and marine environments has been outlined in a study done by University of Adelaide researchers. Published in the journal Proceedings of the National Academy of Sciences, their analysis finds ocean warming and acidification are likely to reduce the diversity of marine species. "Our large-scale analysis suggests that many species will show a decrease in abundance, as well as diversity," Associate Professor Ivan Nagelkerken said. "We looked at how climate...

Climate change could triple Amazon drought, study finds

Washington Post: When thinking about greenhouse gas emissions, there are a few obvious sources that come to mind, such as cars or coal-burning plants. But there are also some huge natural reservoirs of carbon on Earth, known as carbon sinks, which could pour huge amounts of carbon dioxide into the atmosphere if they were unleashed. The worlds forests are one major example. Trees store large amounts of carbon while theyre alive but when they die, they release all that carbon back into the atmosphere. So as...

Seafood hit by climate change
2015-10-12 21:01:00| Climate Ark Climate Change & Global Warming Newsfeed
Sydney Morning Herald: A global marine food chain collapse due to greenhouse gas emissions could hit many popular eating fish, an Australian study has found. Warmer waters, coupled with ocean acidification, mean that the higher a fish is up the food chain, the more imperilled it would be. "They will need more food, but less food will be available - and these are the fish that we like to eat," said University of Adelaide marine ecologist Ivan Nagelkerken?. Tuna catches may be fewer under climate change. The...

Global climate pledges not enough but good start: European Commission
2015-10-12 20:30:00| Climate Ark Climate Change & Global Warming Newsfeed
Reuters: National pledges to cut greenhouse gas emissions, even if fully implemented, would cap global warming at 3 degrees Celsius rather than the 2 degrees targeted to avoid dangerous consequences, the European Commission said on Monday. European Climate and Energy Commissioner Miguel Arias Canete said 149 countries had submitted pledges known in U.N. language as INDCs, or Intended Nationally Determined Contributions, ahead of pivotal climate change talks in Paris in December. "According to our in-house...
