The debate has been marked by considerable controversy, confusion, and opaqueness. The confusion stems from the failure of some scientists, bloggers, reporters,…

The evidence from real-world observations, sophisticated computer models, and research in hundreds of different fields continues to pile up: human-caused climate change is already occurring and will continue to get worse and worse as greenhouse-gas concentrations continue to rise. Because the climate is connected to every major geophysical, chemical, and biological system on the planet,…

On April 2nd, I posted three iconic graphs showing some of the clear observational evidence that we’re changing the climate. That post produced a substantial, and largely thoughtful response, and a request for more information and data along these lines. Here are three more, along with a bonus fourth, all with a theme of exponential…

Here are three iconic graphs (unfortunately, there are many, many more) showing just some of the clear observational evidence that we’re changing the climate. The first is the atmospheric concentration of carbon dioxide, measured at the Mauna Loa observatory in Hawaii. It shows the little ups and downs in concentration that varies with the seasons,…
