And by “Shut. Up.” I mean shut up about whether or not global warming is real.<\/p>\n
The National Climatic Data Center of NOAA has just released the number representing the Earth’s surface temperature for February<\/a> and it is a shocking 0.82 degrees C above the 20th century average. This is the second warmest Feb on record, and I’m pretty sure it is the third warmest month on record, in that data base.<\/p>\n Roughly speaking, the coldest we have experienced, the Last Glacial Maximum, was about 6 degrees colder than at present. It is generally thought that we need to keep the global surface temperature below about 2 degrees C above the preindustrial level. The 20th century average used by NOAA includes decades warmed considerably by human caused greenhouse gas pollution; the actual difference between the best estimate (BEST 1750-1850) of the pre-industrial temperature and the present is about 1.5 degrees C.<\/p>\n This high value is not surprising since the estimate of the Earth’s surface temperature from NASA GISS, which came out a few days ago, also places February very high in temerature<\/a>.<\/p>\n March, by the way, has been pretty warm. We’ve had quite a trend of very warm months, and it appears to not be letting up.<\/p>\n For a comparative perspective, see also this. <\/a><\/p>\n","protected":false},"excerpt":{"rendered":" And by “Shut.
