This month an article came out that honestly gave me a chill. These were climate tipping points – a well-known concept that the climate can change abruptly if certain conditions are met in certain elements of the climate system, such as excessive melting of the Greenland ice sheet. This was nothing new. What was new was the threshold that these seesaws could tip – according to this research, we could already trigger some seesaws – and if we warm the planet by just 1.5°C, then we are *likely * to do.

The climate is still within our control. But if we continue to broadcast as we do, this will not always be the case.

Video on climate tipping points and a new article on climate tipping points, talking about the cessation of thermohaline circulation, thawing of permafrost, collapse of ice sheets and extinction of corals. This new article by McKay et al. shows that there is no clear relationship between cumulative carbon emissions and global warming: there can be incremental changes through internal variability, rapidly pushing the Earth toward different climates. In this video I talk about climate tipping points, how some are already possible today and will become likely with just 1.5°C of warming.
