Climate Change

A great deal of attention about Climate Change is focused on a single iconic plot of global mean temperature. In reality different regions around the global have very different average temperature and time evolution of temperatures. Is the focus on one global average plot propaganda or science?

Increasing levels of carbon dioxide in the atmosphere is thought to be the cause of Anthropogenic Global Warming. This page looks at available data for atmospheric carbon dioxide concentrations, both from ground observatories and from satellites.

An enormous number of models exist to make predictions about the future evolution of the climate but many models already disagree with existing data.

Explanation of Greenhouse effect and Climate Sensitivity

Summer 2023 saw a great deal of media fuss about excessive temperatures. This page shows that the situation was very much exaggerated and the global temperature fluctuations were due to frequent natural ocean oscillation phenomena: ENSO and NAO.

The Arctic region is the region of the world with the highest current rate of increase in temperature during the period 1979-2022. This page show various plots of global mean surface temperature data for Arctic land regions. These plots show large bumps in the temperature values in the years 1935-1945.
