The World Meteorological Organisation have released a report on the levels of greenhouse gases within the atmosphere in 2016. Measurements of the levels of greenhouse gases in the atmosphere were taken in 51 countries and tested the levels of gases such as nitrous oxide, carbon dioxide and methane. Experts say that the last time levels of these gases and carbon dioxide were last seen around 800,000 years ago.
The last time that carbon dioxide levels were this high was around 3 to 5 million years ago. During the time that temperatures were 2-3°C warmer than current temperatures and sea levels were around 10 to 20 metres higher. Experts at the World Meteorological Organisation have stated that the findings of the report could lead to severe ecological and economic disruptions, meaning that this is a cause for concern.
