The planet’s long-term warming trend has continued through 2018, with the average global temperature set to be the fourth-highest on record, reports the World Meteorological Organization, which is based in Geneva, Switzerland.
The 20 warmest years on record have been the past 22 years with the top four in the past four years, WMO reported.
The global average temperature for the first 10 months was nearly 1 degree Celsius above the pre-industrial baseline established 1850 to 1900.
The industrial revolution began in England in the late 1700s and spread throughout the world, marking the beginning of greenhouse gas emissions, the leading cause of global warming. Greenhouse gases include water vapor, carbon dioxide, methane and nitrous oxide.
The goal of the Paris Climate Agreement is to limit global warming to 1.5 degrees Celsius to 2 degrees Celsius
The average global temperature for the decade 2006 to 2015 was 0.86 degrees Celsius.
The average increase from 2009 to 2018 was about 0.93, and from 2014-2018, it was 1.03 degrees Celsius.
The planet already is seeing and fleeing the effects of warming temperatures.
These markers include melting sea ice, rising sea levels, extreme weather, including flooding and wildfires, heatwaves and drought, colder temperatures, heavier snowfalls and tropical storms.
