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.

Stratosphere Temperatures

Lower stratosphere temperatures since the 1950s. As the lower atmosphere warms, compensation occurs in the stratosphere in the form of cooling. Venus shows this nicely - while its lower atmosphere is above 800 degrees, its upper atmosphere is about 5 times cooler than ours. It's called radiative transfer - the stratosphere isn't going to cool unless the lower atmosphere warms, although it's not a 1-1 ratio:
