Heat Records Beaten World Wide

Heat Records Falling Around the World in 2018

  A sampling of all-time high temperatures reported around the world in 2018 thus far, rounded to the nearest degree Fahrenheit. Most of these were set in late June and early July (see details below). The reading of 51.3°C (124.3°F) at Ouargla, Algeria, is the highest reliably measured temperature on record for Africa.

The first five months of 2018 were the fourth warmest in global records going back to 1880, according to NOAA. Along the way, a number of extreme heat events have occurred already this year. In recent weeks across the Northern Hemisphere, these records have included an impressive number of all-time highs (an all-time high is the warmest temperature reported on any date at a given location). 
Setting an all-time high is no small accomplishment, especially for locations that have long periods of record (PORs). All-time highs are especially noteworthy when you consider that, on average, the planet is warming more during winter than during summer, and more at night than during the day. Urban heat islands are no doubt contributing somewhat to the heat records achieved in large urban areas, but the extreme heat of 2018 has also played out in remote rural areas without any urban heat islands.
I wish some climate change denier would tell me at what point will breaking high temperatures get them to admit that global warming is happening.

Alaska Crushes Record For Hottest December

Alaska crushes record for hottest December as Arctic sea ice hits record low In its hottest December ever recorded, Alaska was a stunning 15.7°F above the 20th century average. And the year ended with Arctic sea ice hitting an all-time record low. While the East Coast had a cool December and New Year’s week, Alaska baked. Last Tuesday, Anchorage hit 48°F , warmer than southern cities from Atlanta and Jacksonville to Houston and New Orleans. The National Oceanic and Atmospheric Administration (NOAA) reported this week that Alaska averaged 19.4°F for the month, topping the previous record (1985) by a whopping 2.1°F. “That’s really quite astonishing,” said Rick Thoman, the National Weather Service’s climate sciences and services manager for the Alaska region. As he explained to the Anchorage Daily News , “Usually you’re breaking those by a tenth of a degree or two-tenths of a degree.” The Arctic as a whole was so warm in December that Arctic sea ice set a new end-of-year record lo

The World My Grandchildren Will Inherit

I went to a presentation at the University of Washington by Professor Raftery of the Statistics and Sociology Departments of a recent paper of his and colleagues (Alec Zimmer, Dargan M.W. Frierson, Richard Startz, and Peiran Liu) in the Journal Nature, entitled Less than 2 °C warming by 2100 unlikely   (link behind a paywall) . Their paper is a response to a need to provide a statistical forecast for global temperatures.  What the IPCC has previously provided are "scenarios" based on "expert" thinking.  Raftery has previously developed statistical methods for estimating world-wide migration patterns that has been adopted by the United Nations.  At the presentation he presented a statistical model for forecasting global temperatures. Their result is a 90% interval forecast of 2 to 4.9 degrees Centigrade with a median of 3.2 degrees. Their backtesting strongly supported the median.  He also  said " that the data suggested that future improvements in ca
