The modeling results indicate that, if nations continue to increase their emissions of greenhouse gases in a «business as usual» scenario, the U.S. ratio of daily record high to record low temperatures would increase to about 20 - to - 1 by mid-century and 50 - to - 1 by 2100.

``... the three researchers write that they «provide experimental support for suggestions and simulation studies predicting that reductions in CO2 alone could have led to loss of tree cover in grassy environments in the last glacial (Bond et al., 2003; Harrison and Prentice, 2003),» and they say that «the large increases in CO2 from industrial emissions over the last century would now favor trees at the expense of grasses,» which conclusion is supported by palaeo - records that indicate that «trees disappeared from current savanna sites in South Africa during the Last Glacial Maximum (Scott, 1999), re-appeared in the Holocene, and have rapidly increased over the last half century,»...

A crucial question raised was why CH4 emissions in this region have been stable over recent decades, whereas many process - based models indicate that increasing temperatures should have led to a detectable increase in emissions.

Projections of future summer mean WBGT under the RCP8.5 emissions scenario that are constrained by observations indicate that by 2030s at least 50 % of the summers will have mean WBGT higher than the observed historical record value in all the analyzed regions, and that this frequency of occurrence will increase to 95 % by mid-century.

«Climate science» as it is used by warmists implies adherence to a set of beliefs: (1) Increasing greenhouse gas concentrations will warm the Earth's surface and atmosphere; (2) Human production of CO2 is producing significant increases in CO2 concentration; (3) The rate of rise of temperature in the 20th and 21st centuries is unprecedented compared to the rates of change of temperature in the previous two millennia and this can only be due to rising greenhouse gas concentrations; (4) The climate of the 19th century was ideal and may be taken as a standard to compare against any current climate; (5) global climate models, while still not perfect, are good enough to indicate that continued use of fossil fuels at projected rates in the 21st century will cause the CO2 concentration to rise to a high level by 2100 (possibly 700 to 900 ppm); (6) The global average temperature under this condition will rise more than 3 °C from the late 19th century ideal; (7) The negative impact on humanity of such a rise will be enormous; (8) The only alternative to such a disaster is to immediately and sharply reduce CO2 emissions (reducing emissions in 2050 by 80 % compared to today's rate) and continue further reductions after 2050; (9) Even with such draconian CO2 reductions, the CO2 concentration is likely to reach at least 450 to 500 ppm by 2100 resulting in significant damage to humanity; (10) Such reductions in CO2 emissions are technically feasible and economically affordable while providing adequate energy to a growing world population that is increasingly industrializing.
