Long-Awaited 'Jump' In Global Warming Now Appears 'Imminent'

Long-Awaited 'Jump' In Global Warming Now Appears 'Imminent' | ThinkProgress

I interviewed Trenberth this week, and he told me that he thinks “a jump is imminent.” When I asked whether he considers that “likely,” he answered, “I am going to say yes. Somewhat cautiously because this is sticking my neck out.” Trenberth explained that it’s significant the Pacific Decadal Oscillation (PDO) “seems to have gone strongly positive” because that is “perhaps the best single indicator to me that a jump is imminent.” During a PDO, he explains, “the distribution of heat in the oceans changes along with some ocean currents.”

Dick Lindzen on cold and heat extremes

Gavin Schmidt and Richard Alley made some comments on extreme weather here .  Dick Lindzen (via email) on cold and heat extremes: "Gavin and Alley both seem pretty ignorant.  Extremes of both cold and heat depend on advection by baroclinic eddies.  This should get weaker in a warmer climate (assuming polar amplification which is another dicey matter).  Alley is assuming that one just adds the change in global mean temperature to any current extreme.  Marc shouldn’t be so defensive.  He’s not dealing with experts.  On the other hand, perhaps it should be noted that the reduction in extremes is ‘consistent’ with global warming."

NOAA settled science: Earth at 58.24F in 2014 was allegedly hotter than Earth at 62.45F in 1997

NOAA Global Analysis- Annual 1997 The global average temperature of 62.45 degrees Fahrenheit for 1997 was the warmest year on record, surpassing the previous record set in 1995 by 0.15 degrees Fahrenheit NOAA Global Analysis- Annual 2014 The average temperature for the year [2014] was 0.69°C (1.24°F) above the 20th century average of 13.9°C (57.0°F) [ie 58.24F ] , beating the previous record warmth of 2010 and 2005 by 0.04°C (0.07°F).

Eric Holhaus on skeptics: "crowd is like 1980s military uniform-type people"

Meet Eric Holthaus, the Rebel Nerd of Meteorology | Culture | Rolling Stone "He covers everything from super typhoons in Hong Kong to walking conditions in Atlanta, tying it all back to the warming planet – which is something many of his colleagues refuse to do. Amazingly, according to one study, nearly half of all US meteorologists don't believe that humans are the cause of climate change. Holthaus has met this contingent at conferences. "The crowd is like 1980s military uniform-type people," he says. "They're prominently conservative Republicans in positions of power, and they want to push the message they believe, politically.""
