From the Socialist Fifth Column, National Oceanic and Atmospheric Administration (NOAA):

2417
  • Greenhouse gases were the highest on record. Major greenhouse gas concentrations, including carbon dioxide (CO2), methane and nitrous oxide, rose to new record high values during 2015. The 2015 average global CO2 concentration was 399.4 parts per million (ppm), an increase of 2.2 ppm compared with 2014.
  • Global surface temperature was the highest on record. Aided by the strong El Niño, the 2015 annual global surface temperature was 0.76–0.83 degrees F (0.42°–0.46°C) above the 1981–2010 average, surpassing the previous record set in 2014.
  • Sea surface temperature was the highest on record. The globally averaged sea surface temperature was 0.59–0.70 degrees F (0.33°–0.39°C) above average, breaking the previous mark set in 2014.
  • Global upper ocean heat content highest on record. Upper ocean heat content exceeded the record set in 2014, reflecting the continuing accumulation of heat in the ocean’s top layers.
  • Global sea level rose to a new record high in 2015. It measured about 2.75 inches (70 mm) higher than that observed in 1993, when satellite record-keeping for global sea level rise began.
  • Tropical cyclones were well above average, overall. There were 101 tropical cyclones total across all ocean basins in 2015, well above the 1981-2010 average of 82 storms. The eastern/central Pacific had 26 named storms, the most since 1992. The North Atlantic, in contrast, had fewer storms than most years during the last two decades.
  • The Arctic continued to warm; sea ice extent remained low. The Arctic land surface temperature in 2015 was 2.2 degrees F (1.2°C) above the 1981-2010 average, tying 2007 and 2011 as the highest on record. The maximum Arctic sea ice extent reached in February 2015 was the smallest in the 37-year satellite record, while the minimum sea ice extent that September was the fourth lowest on record.
