Climate Change Temperature Forecasts

2010 - 2020 Decade Temperatures

2010 – 2019. Stanford computer models project a dramatic spike in extreme seasonal temperatures during the period 2010 - 2019. “The Stanford team also forecast a dramatic spike in extreme seasonal temperatures during the current decade [2010 – 2019]. Temperatures equaling the hottest season on record from 1951 to 1999 could occur four times between now [2010] and 2019 over much of the U.S., according to the researchers. The 2020s and 2030s could be even hotter, particularly in the American West.” (Mark Shwartz, communications manager, Woods Institute for the Environment at Stanford University, “Heat waves and extremely high temperatures could be commonplace in the U.S. by 2039, Stanford study finds,” Stanford Report, July 8, 2010 citing findings in Diffenbaugh, N., and M. Ashfaq. Intensification of hot extremes in the United States. Geophys. Res. Lett., (in press) DOI: 10.1029/2010GL043888, August 6, 2010)

2014 | Climate Change Temperatures

2014. Britain’s Met Office projects 2014 temperature likely to be 0.3 degrees Celsius warmer than 2004. “Here is the climate forecast for the next decade [2007-2014]; although global warming will be held in check for a few years, it will come roaring back to send the mercury rising before 2014. This is the prediction of the first computer model of the global climate designed to make forecasts over a timescale of around a decade, developed by scientists at the Met Office. The new model developed at the Met's Hadley Centre in Exeter, and described in the journal Science, predicts that warming will slow during the next few years but then speed up again, and that at least half of the years after 2009 will be warmer than 1998, the warmest year on record.

Over the 10-year period [2007-2014] as a whole, climate continues to warm and 2014 is likely to be 0.3 deg C [0.3 degrees Celsius] warmer than 2004. The overall trend in warming is driven by greenhouse gas emissions but this warming effect will be broadly cancelled out over the next few years by the changing patterns of the ocean temperatures.” (Roger Highfield, Science Editor, “Global warming forecast predicts rise in 2014,” The Daily Telegraph, London, England, United Kingdom, August 9, 2007 reporting findings in Doug M. Smith, Stephen Cusack, Andrew W. Colman, Chris K. Folland, Glen R. Harris, and James M. Murphy, “Improved Surface Temperature Prediction for the Coming Decade from a Global Climate Model,” Science, August 10, 2007 317: 796-799 DOI: 10.1126/science.1139540)

2020. Temperatures on Earth projected by 2020 to be at the hottest levels in 150,000 years. “Astronomer and author Carl Sagan says a closer look at Venus could help inspire Earth's residents to break their dependence on fossil fuels. Speaking to more than 1,000 people Thursday [September 13, 1990] at the College of Southern Idaho, Sagan said Venus is an incredibly hot, barren planet because of the intense greenhouse effect there. And that should be a lesson to people on Earth, which faces a worsening greenhouse effect with the continued use of fuels like oil and coal, which produce carbon dioxide that traps heat in the atmosphere.

‘Every lump of coal burned, every gallon of gas, puts carbon dioxide in the air,’ Sagan said. ‘Doubters of the greenhouse effect need look no farther than Venus, which has lots of carbon dioxide and surface temperatures of 900 degrees Fahrenheit.’ If the buildup of carbon dioxide continues in the Earth's atmosphere, he said, temperatures on Earth are projected to be at their hottest level in 150,000 years by the year 2020.” (Carl Sagan quoted in “Sagan Says Fossil-Fuel Use May Turn Earth Into A Venus,” The Deseret News, Salt Lake City, Utah, September 16, 1990, p. B4) See Carl Sagan's published works, documentaries and video of Carl Sagan and Stephen Hawking on climate disruption and global warming.

2020. Stanford study projects that intense heat waves are likely to occur as many as five times between 2020 and 2029 over areas of the western and central U.S. “Exceptionally long heat waves and other hot events could become commonplace in the United States in the next 30 years [2010 – 2039], according to a new study by Stanford University climate scientists. ‘Using a large suite of climate model experiments, we see a clear emergence of much more intense, hot conditions in the U.S. within the next three decades,’ said Noah Diffenbaugh, an assistant professor of environmental Earth system science at Stanford and the lead author of the study. . . . The [study, Intensification of hot extremes in the United States], took two years to complete and is co-authored by Moetasim Ashfaq, a former Stanford postdoctoral fellow now at the Oak Ridge National Laboratory.

The study comes on the heels of a recent NASA report that concluded that the previous decade, January 2000 to December 2009, was the warmest on record. . . . ‘This was an unprecedented experiment,’ Diffenbaugh said. ‘With the high-resolution [RegCM3] climate model, we can analyze geographic quadrants that are only 15.5 miles [25 kilometers] to a side. No one has ever completed this kind of climate analysis at such a high resolution.’ The results were surprising.

According to the climate models, an intense heat wave – equal to the longest on record from 1951 to 1999 [a period of 48 years] – is likely to occur as many as five times between 2020 and 2029 [a period of 9 years] over areas of the western and central United States. . . .

Besides harming human health and agriculture, these hot, dry conditions could lead to more droughts and wildfires in the near future, he said. And many of these climate change impacts could occur within the next two decades [2010-2030] -- years before the planet is likely to reach the 2-degree C threshold targeted by some governments and climate experts, [Diffenbaugh] added.” (Mark Shwartz, communications manager, Woods Institute for the Environment at Stanford University, “Heat waves and extremely high temperatures could be commonplace in the U.S. by 2039, Stanford study finds,” Stanford Report, July 8, 2010 citing findings in Diffenbaugh, N., and M.
