LAST week a team of scientists published their review of the evidence that has accumulated in the past few years about the properties and dangers of climate tipping points.

They compared this evidence with the 1.5-2°C rise in global temperature that will occur under the Paris Agreement. They found that we may still reach several climate tipping points or maybe have already crossed them.

A ”tipping point” is when a variable in a system, such as the global temperature in our climate, crosses a threshold which causes feedback.
