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.

Atmospheric Carbon-14 Ratios

Carbon-14 has a short half life, thus it is not found in ancient fossil fuels. Burning these fuels then decreases the 14C/12C ratio in the atmosphere. This is a measurement of 14C levels from 1820 up until about 1950. Nuclear bomb tests in the late-40s and 50s put large amounts of 14C into the atmosphere, so records after that date cannot be used, Specifically, tree ring data from after 1960 is unreliable because of the nuclear testing, so it is not used in climate modeling:
