More details about global temperature are available in the State of the Climate reports (Global Analysis) at the NOAA-NCDC website. These reports present preliminary, global data that has been gathered from monitoring stations and leading institutions around the world. The reports include a Global Hazardssection that gives a global update on drought & wildfires, flooding, storms, severe winter weather, and ecosystems impacts. A Snow and Ice section reports on snow cover in the Northern Hemisphere and sea ice extent in the Northern and Southern Hemispheres.
NOTE: Global temperatures set out in the CO2Now graphic (above) are computed from preliminary NOAA estimates of global average temperature for the 20th century and adding the current 20th-century anomaly.
