– 1 degree –

Earth’s average surface temperature from January to October 2018 was one degree Celsius (1.8 degrees Fahrenheit) higher than the 1850-1900 baseline.

Long-term warming is caused by the accumulation of heat-trapping greenhouse gases in the atmosphere, especially carbon dioxide (CO2) cast off when fossil fuels are burned to produce energy.

Seventeen of the hottest years on record have occurred since the start of the 21st century, with 2018 ranking as the 4th warmest.

– 405.5 ppm –

The concentration of carbon dioxide (CO2) in the atmosphere reached 405.5 parts per million (ppm) in 2017, the highest in at least three million years and a 45 percent jump since the preindustrial era.

The last time CO2 was at that level, oceans were 10-20 metres higher.
