Good thing global warming is “A Chinese Hoax“, eh trumptards?
2017 set a number of climate records including the highest sea levels, according to the American Meteorological Society’s newly-released 2017 State of the Climate report.
Global mean sea level in 2017 was the highest annual average in the satellite altimetry era (since 1993), measuring 77mm (three inches) above the 1993 average. Levels have risen year to year for six consecutive years and in 22 of the last 24 years. Regional variations were evident, with differences attributed to changes climatic conditions such as trade wind strength.
While the global average sea surface temperature in 2017 was slightly below the 2016 value, the long-term trend remained upward, with the last three years seeing the three highest annual average temperatures on record. Variations existed among ocean regions. Compared to 2016, the sea surface in 2017 was mostly cooler in the tropical and subtropical oceans, while warming took place in the mid latitudes
The year also including the highest global temperature for a non-El Niño year, lowest Arctic sea ice extent and highest greenhouse gas (carbon dioxide, methane and nitrous oxide) concentrations. Additionally, the year saw a wide swing of precipitation extremes, with some areas experiencing extended droughts and others notable precipitation, for example during Severe Tropical Cyclone Debbie in Australia and New Zealand and Hurricane Harvey in the U.S.
