The IPCC assumes CO2 concentration will reach 836 ppmv by 2100, but, for almost eight years, CO2 concentration has headed straight for only 570 ppmv by 2100. This alone halves all of the IPCC’s temperature projections.
Since 1980 temperature has risen at only 2.5 °F (1.5 °C)/century, not the 7 F° (3.9 C°) the IPCC imagines.
Sea level rose just 8 inches in the 20th century and has been rising at just 1 ft/century since 1993. Sea level has scarcely risen since 2006. Also, Pacific atolls are not being drowned by the sea, as some have suggested.
Arctic sea-ice extent is about the same as it has been at this time of year in the past decade. In the Antarctic, sea ice extent – on a 30-year rising trend – reached a record high in 2007. Global sea ice extent shows little trend for 30 years.
Hurricane and tropical-cyclone activity is at its lowest since satellite measurement began.
Solar activity has declined again, after a large sunspot earlier in the month. The Sun is still very quiet.
The (very few) benefits and the (very large) costs of the Waxman/Markey Bill are illustrated. The Bill would cost trillions and achieve nothing.
Science Focus this month studies the effect of the Sun on the formation of clouds. IT’S THE SUN, STUPID!
