Greenhouse gases that trap heat in the earth's atmosphere resulted in Global Warming reaching the highest levels ever record in 2018.

A new report published by the American Meteorological Society and compiled by the US government compared the last 60 years of modern climate data as well as 800,000 years of ice core data.  Researchers found that atmospheric carbon dioxide - the result of human activities such as driving cars or burning fuel - was 407.4 parts per million, 2.4 ppm higher than in 2017.  

The warming influence of CO2 in the atmosphere is 43 percent higher today than it was in 1990.  That resulted in 2015, 2016, 2017, and 2018 being the planet's hottest years on record.  Sea levels are the highest on record, and the world average surface temperature is near a record.

Despite the denials issued by do-nothing politicians, the US National Oceanic and Atmospheric Administration (NOAA) said the report "found that the major indicators of climate change continued to reflect trends consistent with a warming planet".
