El Niño

Global average CO2 concentrations rose at a record rate in 2016 to more than 403 parts per million up from 400.00 ppm in 2015, according to the World Meteorological Organization. Concentrations of CO2 are now nearly 50% higher than pre-industrial levels.

There’s more CO2 in the atmosphere now than any point in almost a million years


The World Meteorological Organization says atmospheric concentrations of CO2 surged to a new record level in 2016. That puts even greater pressure for countries to cut carbon pollution to avoid catastrophic climate change.

The current El Niño may hold lessons for how to deal with a warming planet


As scientists have been predicting since 2014, a powerful El Niño in the Pacific ocean is triggering extreme weather events and changes in weather patterns around the world. Some climate scientists are saying the lessons learned from this El Niño could help the world cope with the weather changes we can expect from climate change.
