2019 was second-warmest year on record
Earth’s global average surface temperature was 1.71°F (0.95°C) above the 20th-century average in 2019. Nine of the 10 warmest years on record have occurred since 2005.
$1.16 trillion in damages
Over the past 15 years (2005-2019), there have been 156 separate billion-dollar weather or climate disasters in the U.S that have cost a combined $1.16 trillion in damages.
28 times more efficient
Methane is roughly 28 times more efficient at trapping heat in the Earth’s atmosphere compared to carbon dioxide, and current levels of methane in the atmosphere are higher than at any point in the past 2,000 years.
Largest solar energy collector?
The ocean is the largest solar energy collector on Earth and can absorb large amounts of heat without big increases in temperature. This ability gives the ocean a central role in stabilizing Earth’s climate system.
Earth’s 'Roaring Forties' are not mirror images
Thanks to less friction from land masses, the blustery westerly winds that dominate the latitudes near 40 degrees — the “Roaring Forties”— are stronger in the Southern Hemisphere than in the Northern.
A month-long cyclone?
The longest-lived tropical cyclone (hurricane) on record was the Pacific’s Hurricane John, which lasted 31 days in 1994, from August 10–September 10.

About NOAA Climate.gov //
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.
About NCEI //
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.
