Greenhouse gas emissions climbed to all-time highs in 2017 and reached the highest levels ever in 800,000 years. In a recent report by the U.S. National Oceanic and Atmospheric Administration, the annual global average carbon dioxide concentration at the Earth’s surface in 2017 was the “highest in the modern atmospheric measurement record”. The global growth rate of CO2 has nearly quadrupled since the early 1960s. The latest edition of this report was released a year after the US - the world’s second-largest polluter after China - withdrew from the landmark 2015 Paris climate accord, in which 170 countries committed to reductions in carbon emissions. Levels of CO2 are reportedly 145 percent higher than pre-industrial levels, which is being blamed for the growing number of natural weather-related disasters around the world.
