1.5 Celsius by 2100 - Is it achievable? Download 1.5 Business Leadership

Using the graph below we estimate four scenarios for global warming, using a combination of actual data gathered between 1980 – 2020 as well as estimated data between 2020 and 2100. We plot the potential outcomes, ranging from no change in anthropogenic global warming which could result in a 3.1°C or higher by the end of the century or a significant substantial change in anthropogenic global warming which could result in either a 2.0°C limit in global warming or further reduction of 1.50°C. Is it still possible to achieve 1.50°C by the end of the century? 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

The above graph, shows four scenarios illustrating how global temperature of land and ocean could increase over time. In 2020, actual data from NASA confirms that global warming is currently at 1.0°C. Between 1980 and 2000 global warming approximately rose by 0.3°C. Twenty years later (2000 – 2020) the upward trend of global warming increased by 0.5°C. If there is no significant change in anthropogenic global warming, the global temperature could rise to 3.1°C or higher by the end of the century based on the assumption of 0.5°C increase every twenty years. If there is a significant substantial change in anthropogenic global warming, between 2020 and 2050, with the global temperature maintained below 1.0°C then by 2100 1.5°C could be envisaged.
