1.5°C vs 2°C Global Warming

Kevin Trenberth

Former Coordinating Lead Author of the IPCC

It is crucial to limit and slow down global warming, and this cannot be emphasised enough. Every small increase in temperature is accompanied by a corresponding increase in hot extremes, severe storms, droughts, rising oceans etc. Join Kevin, as he talks us through the importance of rates of change vs one-off climate events, along with the differences the planet will see at 1.5 vs 2 degrees of warming.

Overview

It is clear climate change is having an impact on the planet, every year climate events seem to get bigger and last longer. An IPCC report highlighted the importance of attempting to limit warming to 1.5 degrees vs 2 degrees. With every incremental increase in temperatures, we see increased hot extremes, more extreme storms, worsening droughts, rising oceans, loss of species, food shortages, health risks and increased poverty and displacement. It is imperative that everyone on the planet attempts to limit and slow down the rate of warming.

Key learning objectives:

  • Understand the difference between rates of change vs one-off climate events

  • Outline how different 1.5°C vs 2°C warming looks
