Global surface temperature was record warm in 2015, moving ahead of the record set just last year by 0.29°F—the largest margin by which one year has ever beaten another since official records began in 1880.
Most major hurricanes in a season
In 1950, there were 8 major hurricanes (Category 3 or higher) in the Atlantic basin, the most of any Atlantic season on record between 1851-2010.
Billion-dollar disasters in 2015
In 2015, there were 10 weather and climate disaster events with losses exceeding $1 billion each across the United States. These events included a drought event, 2 flooding events, 5 severe storm events, a wildfire event, and a winter storm event.
Earth's surface temperature
Since the historical climate record began in the 1880s, Earth's average surface temperature has risen by 1.6°F (0.88°C) through 2014, which is a rate of 1.2°F (0.66°C) per century.
Climbing carbon dioxide
By burning fossil fuels for energy, human activities have increased the concentration of carbon dioxide in the atmosphere by more than 40% since the Industrial Revolution, causing global warming and making the pH of the ocean more acidic.
NOAA Climate.gov provides timely and authoritative information about climate. We promote public understanding of climate science and climate-related events through videos, stories, images, and data visualizations; we make common data products and services easy to access and use; and we provide tools and resources that help people make informed decisions about climate risks, vulnerability, and resilience.
The National Centers for Environmental Information (NCEI) host and provide access to one of the most significant archives on earth, with comprehensive oceanic, atmospheric, and geophysical data. From the depths of the ocean to the surface of the sun and from million-year-old tree rings to near-real-time satellite images, NCEI is the nation’s leading authority for environmental information.
