Climate change, caused by burning fossil fuels, is unequivocally warming the Earth’s temperature, NASA scientists said.

And El Niño, the natural climate pattern in the tropical Pacific that brings warmer-than-average sea-surface temperatures and influences weather, has only just started in recent months and therefore is not having a huge impact yet on the extreme heat people around the globe are experiencing this summer, said Gavin Schmidt, a climatologist and director of the NASA Goddard Institute for Space Studies.

Long-lost Greenland ice core suggests potential for disastrous sea level rise “It’s really only just emerged, and so what we’re seeing is not really due to that El Niño,” Schmidt told reporters. “What we’re seeing is the overall warmth pretty much everywhere – particularly in the oceans. … The reason why we think that’s going to continue is because we continue to put greenhouse gases into the atmosphere. Until we stop doing that, temperatures will keep on rising.”
