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.

Arctic Oscillation

Stratospheric cooling results in counterclockwise circulation around the North Pole (the Arctic Oscillation) to strengthen in winter, its positive phase, acting to keep the polar jet stream north of the 45th parallel. In its positive phase, the AO results in warmer winters in the US, Scandinavia, and Russia.
