We give a comprehensive overview of the causes, magnitude and impacts of climate change. A lot of the relevant climate data are available on the internet but they are not presented in a way which makes them easy to understand. Where climate data are available in a digestible form they are often presented in a biased way. On this site you will find graphs, explanation and data related to essential aspects of climate change. Everything can be downloaded for free and the data files can be input directly to spreadsheets on Windows, Macintosh and UNIX operating systems. The climate information and data are available in the following subject areas:
- Temperature - observed and climate model simulations of Global, European and American temperature.
- Precipitation - observed and climate model simulations of Global, European and American precipitation.
- Proxy data: (i) Ice Cores - Antarctic, Arctic and glaciers with temperature and other data for 100s of thousands of years. (ii) Tree Rings - data from northern and southern hemisphere countries with temperature estimates for 100s of years.
- Forcing – Natural: albedo (reflectivity) of earth; orbital variations (Milankovitch cycles) ; sun-spots; El Niňo and other oscillations; radio-sonde temperature profiles. Gases: variation of CO2 and methane over time and a break-down of CO2 by source and geographical origin; the influence of greenhouse gases on climate.
- Climate Impacts - Global sea level; snow cover, Arctic and Antarctic sea ice; tropical cyclones; polar bears.
