Climate models overestimate increase in wet and dry extremes

Climate Home: The 20th century was neither much drier nor wetter for half the globe than many of its predecessors, European scientists say. On the contrary, they say several centuries in the last 1,200 years experienced much more variable rain and drought than the 1900s. Their findings, which are published with several caveats and which have not so far been replicated, differ markedly from the conclusions published by the Intergovernmental Panel on Climate Change (IPCC). In what they say is the first...
Climate-change models wrong on predicting rain, drought extremes

Washington Times: A newly released international study debunks climate models on global warming that forecast extreme rainfall and drought tied to temperature swings, casting doubt on disaster scenarios promoted by the climate-change movement. The study in the journal Nature published Thursday examining Northern Hemisphere rainfall data going back 1,200 years found that today`s climate models were frequently wrong on predicting extreme rain and drought. In the 20th century, for example, higher-than-average temperatures...

Climate data since Vikings cast doubt on more wet, dry extremes

Reuters: OSLO Climate records back to Viking times show the 20th century was unexceptional for rainfall and droughts despite assumptions that global warming would trigger more wet and dry extremes, a study showed on Wednesday. Stretching back 1,200 years, written accounts of climate and data from tree rings, ice cores and marine sediments in the northern hemisphere indicated that variations in the extremes in the 20th century were less than in some past centuries. "Several other centuries show stronger...
Climate extremes threaten Australias wine industry

Reuters: Winemakers in Australia's oldest growing region fear a ruined harvest after heavy rainfall, while vineyards in the country's west are under threat from bushfires, undermining efforts to recover from a near decadelong run of lower exports. Just weeks out from the 2016 harvest, the contrasting events highlight the challenges from climate change, particularly extreme weather, faced by the world's fourth-largest wine exporter. Not only are wine growing regions getting hotter, weather is also becoming...

Weather Extremes Slash Cereal Yields
2016-01-09 17:24:00| Climate Ark Climate Change & Global Warming Newsfeed
Climate News Network: Climate change may have already begun to take its toll of agriculture. New research suggests that drought and extreme heat in the last 50 years have reduced cereal production by up to 10%. And, for once, developed nations may have sustained greater losses than developing nations. Researchers have been warning for years that global warming as a consequence of rising levels of carbon dioxide in the atmospherein turn, a pay-off from increased fossil fuel combustionwill result in a greater frequency...
