According to Judd, accurate temperature estimates of ancient oceans are vital because they are the best tool for reconstructing global climate conditions in the past, including metrics like mean global temperature and the latitudinal temperature gradient.

Key Points: 
  • According to Judd, accurate temperature estimates of ancient oceans are vital because they are the best tool for reconstructing global climate conditions in the past, including metrics like mean global temperature and the latitudinal temperature gradient.
  • Knowing how those regions are biased in comparison to the global mean allows researchers to better interpret the proxy data coming from the ancient Earth.
  • We highlight where, when and why temperature estimates from the same latitudes may differ from one another and compare different climate models abilities to reconstruct these patterns.
  • Our work therefore lays the groundwork to more holistically and robustly reconstruct global climate through Earths history.

WASHINGTON, Jan. 15, 2020 /PRNewswire/ --According to independent analyses by NASA and the National Oceanic and Atmospheric Administration (NOAA), Earth's global surface temperatures in 2019 were the second warmest since modern recordkeeping began in 1880.

Key Points: 
  • WASHINGTON, Jan. 15, 2020 /PRNewswire/ --According to independent analyses by NASA and the National Oceanic and Atmospheric Administration (NOAA), Earth's global surface temperatures in 2019 were the second warmest since modern recordkeeping began in 1880.
  • Globally, 2019 temperatures were second only to those of 2016 and continued the planet's long-term warming trend: the past five years have been the warmest of the last 140 years.
  • "The decade that just ended is clearly the warmest decade on record," said GISS Director Gavin Schmidt.
  • NOAA found the 2019 annual mean temperature for the contiguous 48 United States was the 34th warmest on record, giving it a "warmer than average" classification.
