Masters/Mann/Field continue to promote the greatest scientific fraud in human history; Field suggests that emitting CO2 is like talking on a cell phone while driving

"We're seeing an increase in extremes of high temperatures, an increase in extremes of heavy precipitation, an increase in the length and severity of droughts," said Chris Field, director of the Carnegie Institution's Department of Global Ecology at Stanford University.
...Jeff Masters, director of meteorology for the website Weather Underground, said it's unlikely so many extremes would naturally occur in such a short period. He cited two major droughts in the Amazon in 2005 and 2010, and Colombia's 2010 rains, which were the heaviest in at least 42 years.

"I think you really have to point the finger at human-caused climate change as having tipped the scales to make previously unprecedented weather events more possible, and multiple unprecedented weather events like we're seeing," Masters said. "There is so much regular variation in the weather, and it's hard to pick out the signal from the noise. But the signal's sure getting pretty strong now."

Field likened the influence of global warming to talking on a cell phone while driving. "There are always traffic accidents, but if you throw people talking on cell phones in the mix, you increase the probability," Field said. "The role of climate change and weather-related extremes is similar."

Michael Mann, director of the Earth System Science Center at Penn State University, said a warming climate has become "part of the fabric — the background state — in which all weather happens."

"The overall character of weather events, with each passing year, is being more and more influenced by human-caused climate change," Mann said.
