“There’s no ambiguity about the data,” said Gavin Schmidt, a climatologist and the director of the NASA Goddard Institute for Space Studies. “So really, it’s a question of attribution.”
Understanding what specific physical processes are behind these temperature records will help scientists improve their climate models and better predict temperatures in the future.
If you read the article, climate change + El Nino + reduced aerosols in the atmosphere + a volcano eruption + a yet unknown factor, which the article is about.
Fair, and bonus points for RTFA.
That said - we know what it’s about. That graph isn’t new. We did this last year too.
Yes but all of those other items are not new, and thus not really responsible.
