Non-partisan, independent presentation of climate data. No political ideology, agenda, or financial incentive. Just the data and the trends from published peer-reviewed research, no matter what it shows. We don't cherry pick. Site owner is a Ph.D. geologist who attempts to present the data in as simple a format as possible, so everyone can understand. Choose a subject from the list, or just scroll down. Data is presented in at-a-glance format with minimal analysis. Climate change is much more than just temperatures.

We don't post often, as there is no need to repost the same data over and over. But we do post data from scientists who have boots on the ground and are doing the dirty fieldwork to collect data.

Sea Ice Extent since 1978

Thinning Antarctic ice sheets have contributed considerable fresh water to the ocean surrounding the continent, especially as basal fresh water releases. This cold fresh water has counterbalanced otherwise warming waters and caused Antarctic sea ice extent to increase since 1979. Note that this is sea ice extent, not volume, and not land glaciers. Data from NSIDC:

Sun's Energy Output since 1970s vs Global Surface Temperature

Is the sun's output driving increased temperatures? Here is a graph from the National Climatic Data Center comparing our sun's energy output since the 1970s with global average surface temperatures:
