Figure 9.4: The maps show projected increases in the average temperature on the hottest days by late this century (2081 - 2100) relative to 1986 - 2005 under a scenario that assumes a rapid reduction in heat - trapping gases (RCP 2.6) and a scenario that assumes continued increases in these gases (RCP 8.5).

Maps show projected change in average surface air temperature in the later part of this century (2071 - 2099) relative to the later part of the last century (1970 - 1999) under a scenario that assumes substantial reductions in heat trapping gases (B1) and a higher emissions scenario that assumes continued increases in global emissions (A2).

However, under business as usual emissions are set to increase global average temperatures by approximately 2.5 °C.

Under the Paris Agreement, Parties have agreed to hold the increase in global average temperature to well below 2 °C and to pursue efforts to limit the increase to 1.5 °C.

The research, led by Australian researchers from the CSIRO and Bureau of Meteorology, predicts that Australia's national average temperature will increase by 2.8 - 5.1 °C by 2090 in a high emissions scenario, compared to 0.6 - 1.7 °C under a low global emissions scenario.

«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.

Increasing the GHG content could, under certain circumstances, increase the radiating efficiency of the atmosphere, particularly at upper levels, lowering the average temperature, like painting a hot stove black.

The frequency and intensity of forest fires in the region have been increasing along with rising temperatures.5, 7,13 An average of around 9.9 million acres (4 million hectares) of boreal forest burned annually in Russia from 1975 to 2005 — and that rate more than doubled in the 1990s.15 One of West Siberia's largest forest fires on record occurred in 2003, claiming some 47 million acres (20 million hectares) of land7, 15 and emitting heat - trapping emissions equal to the total cuts in emissions the European Union pledged under the Kyoto Protocol.2, 7,16 Higher temperatures and thawing permafrost are probably contributing to the rising frequency and severity of forest fires in West Siberia.5, 7,14

In Paris, in 2015, the countries of the world agreed (again) on the moral imperative to hold the rise in global average temperature to under 2 degrees Celsius, and to pursue «efforts to limit the temperature increase to 1.5 degrees.»

According to a recent study by the full range of actions under the bill would lead to emissions reductions of 77 percent below 1990 levels by 2050, a result consistent with what is needed by the international community as a whole to contain the increase of average global temperatures to the catastrophe - averting limit of 2 °C.

Last year was the hottest since records began and with an El Nino now under way the warm surface waters of the Pacific are releasing heat into the atmosphere with the result 2015 is likely to break last year's record and the global average surface temperature could jump by as much as 0.1 degree this year alone bring global surface temperatures increases to 1 degrees or half way to the UN global limit.
