Also published at Skeptical Science This is a climate model: T = [(1-α)S/(4εσ)]1/4 (T is temperature, α is the albedo, S is the incoming solar radiation, ε is the emissivity, and σ is the Stefan-Boltzmann constant) An extremely simplified climate model, that is. It’s one line long, and is at the heart of every computer [...]

The relationship between technology and climate change is complex and multi-faceted. It was technology, in the form of fossil fuel combustion, that got us into this problem. Many uninformed politicians hold out hope that technology will miraculously save us in the future, so we can continue burning fossil fuels at our current rate. However, if [...]

Cross-posted from NextGenJournal Climate change is a worrying phenomenon, but watching it unfold can be fascinating. The beginning of a new year brings completed analysis of what last year’s conditions were like. Perhaps the most eagerly awaited annual statistic is global temperature. This year was no different – partway through 2010, scientists could tell that [...]
Temperatures for July 2009
Posted in News and Reports, tagged climate change, global warming, NCDC, NOAA, science, temperature on August 14, 2009 | 9 Comments »
Much the same story as June. Much of Canada and the US was cooler than normal, but they are clearly the minority: (from NCDC, which is part of NOAA) It was the fifth warmest July on record. The ocean temperatures, quite notably, were the warmest on record. One month like this doesn’t prove a long-term warming [...]
