How Sensitive is climate to CO2?
New study by an international team concludes that if we don’t mitigate our CO2 emissions then we face very severe impacts and risks worldwide

CO2 in Earth’s atmosphere nearing Pliocene levels
New study reveals that by 2024/2025 levels of atmospheric CO2 will be higher than any point in the last 3.3 million years.
Global CO2 emissions still rising despite COVID-19
Atmospheric CO2 has reached a monthly peak exceeding 417 parts per million (ppm) in May 2020, the highest monthly total ever recorded.
How far back can we measure CO2 ?
New Study reveals that today’s CO2 levels are actually higher than they have been for the past 23 million years. How did they work that out?
Global CO2 emissions update
Estimates for the decline of CO2 due to lockdown have been published in Nature. What does this reveal, and what do we do now?
CO2 and COVID-19
It is commonly suggested that the impact of the lockdown is a humble 5% drop in CO2. This number is based upon assumptions that may be wrong.
