August 1, 2018 It's official: 2017 was the third-warmest year on record for the globe, behind 2016 (first) and 2015, according to the 28th annual State of the Climate report. The planet also experienced record-high greenhouse gas concentrations as well as rises in sea level.

The annual checkup for the planet, led by scientists from NOAA's National Centers for Environmental Information and published by the Bulletin of the American Meteorological Society, is based on contributions from more than 500 scientists in 65 countries and offers insight on global climate indicators, extreme weather events and other valuable environmental data.

Notable findings from the international report include:

Levels of greenhouse gases were the highest on record. Major greenhouse gas concentrations in the atmosphere - including carbon dioxide (CO2), methane and nitrous oxide - reached new record highs. The 2017 average global CO2 concentration was 405 parts per million, the highest measured in the modern 38-year global climate record and records created from ice-core samples dating back as far as 800,000 years.

Sea level rise hit a new high - about 3 inches (7.7 cm) higher than the 1993 average. Global sea level is rising at an average rate of 1.2 inches (3.1 cm) per decade.

Unprecedented multiyear coral reef bleaching continued: A global coral bleaching event spanned from June 2014 through May 2017, resulting in unprecedented impacts on reefs. More than 95 percent of coral in some affected reef areas died.

Heat in the upper ocean hit a record high

Arctic and Antarctic sea ice hit record lows
