CLIMATE SCIENCE

"Everything should be made as simple as possible, but no simpler" - Einstein

The science of climate change / global warming is vast. The new 2013 IPCC Science report provides the most authoritative compendia of professional research. An excellent scientific resource is RealClimate, run by professional climatologists. The site Skeptical Science has accessible articles rebutting fake-scientific disinformation on climate science.

Media requesting reliable information on climate science will find a valuable resource in the Climate Science Rapid Response Team (CSRRT).

The 'Wheelchair' and Climate Tipping Points

Shown is the global-mean surface temperature evolution from the Last Glacial Maximum through the Holocene, based on palaeoclimatic proxy data (grey and light blue lines, with the purple and blue shading showing one standard deviation), instrumental measurements since 1750 AD (HadCRUT data, black line) and different global warming scenarios for the future. Threshold ranges for crossing various tipping points where major subsystems of the climate system are destabilized have been added. The range for the West Antarctic Ice Sheet (WAIS) has been adapted to account for the observation that part of it has probably tipped already. THC, thermohaline circulation; ENSO, El Niño–Southern Oscillation; EAIS, East Antarctic Ice Sheet.

SIGNIFICANT NEWS ITEMS

• The last 30 years were probably the warmest since at least 1,400 years. Click for graph of the future temperature development in the highest emissions scenario (red) and in a scenario with successful climate mitigation (blue) – the “4-degree world” and the “2-degree world.”
• Remembering Jerry Mahlman, 1940-2012
