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.

Carbon isotope signatures in coral skeletons

Just carbon isotopes in ocean water represent the atmospheric carbon signature above, coral skeletons are reliable proxies for atmospheric changes. Taken from Swart, et al. (2010), coral skeletons from around the world show the same declining 13C/12C carbon ratio as the atmosphere above. Data from 1800 to 2000.

Short refresher on carbon isotopes: Burning of fossil fuels adds huge amounts 12C to the atmosphere which should yield declining 13C/12C ratios.
