![]() The Intergovernmental Panel on Climate Change (IPCC) states clearly in its AR5 assessment report 4: How much of the warming since 1850 can be attributed to human emissions? Almost all of it. 3 Greenhouse gas emissions from human activities are the main driver of this warming But overall, this temperature rise is in the range of 1 to 1.2℃. Overall, this would amount to an average temperature rise of 1.1℃.īecause there are small year-to-year fluctuations in temperature, the specific temperature increase depends on what year we assume to be ‘pre-industrial’ and the end year we’re measuring from. When extended back to 1850, we see that temperatures then were a further 0.4℃ colder than they were in our baseline. We see that over the last few decades, global temperatures have risen sharply - to approximately 0.7℃ higher than our 1961-1990 baseline. The red line represents the average annual temperature trend through time, with upper and lower confidence intervals shown in light grey. In the chart, we see the global average temperature relative to the average of the period between 19. To set the scene, let’s look at how the planet has warmed. 1 This link between global temperatures and greenhouse gas concentrations – especially CO 2 – has been true throughout Earth’s history.
