In order to achieve the target set by the Paris Agreement --- to limit the rise in global average temperature to below the 2 degree C threshold — all new construction must be designed to high energy efficiency standards and use no CO2 - emitting fossil fuel energy to operate; by 2050 the entire built environment must be carbon neutral.

Based on current knowledge, however, it appears that achieving a high probability of limiting global average temperature rise to 2C will require that the increase in greenhouse - gas concentrations as well as all the other warming and cooling influences on global climate in the year 2100, as compared with 1750, should add up to a net warming no greater than what would be associated with a CO2 concentration of about 400 parts per million (ppm).

«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.

say it has been predicted that «the average temperature in the semiarid northwest portion of China in 2050 will be 2.2 °C higher than it was in 2002,» and they report that based on the observed results of their study, this increase in temperature «will lead to a significant change in the growth stages and water use of winter wheat,» such that «crop yields at both high and low altitudes will likely increase,» by 2.6 % at low altitudes and 6.0 % at high altitudes... Even without the benefits of the aerial fertilization effect and the anti-transpiration effect of the ongoing rise in the air's CO2 content, the increase in temperature that is predicted by climate models for the year 2050, if it ever comes to pass, will likely lead to increases in winter wheat production in the northwestern part of China, not the decreases that climate alarmists routinely predict.»

But given that carbon dioxide levels were now substantially higher than anything in the past two millions of years, in either glacials or interglacials, it had become abundantly clear that the greenhouse effect was something we needed to take extremely seriously: even if the precise future increase in temperature was still an unknown quantity, with a fairly wide error - range, models indicated that for a doubling of carbon dioxide from pre-industrial levels, a rise of three degrees celsius as a global average was the most likely outcome.

Burning fossil fuels not only pollutes our air directly with irritants like particulate matter and soot, but as greenhouse gases accumulate in the atmosphere and average temperatures rise, they also contribute to higher levels of ground - level ozone that can cause acute and long - term respiratory problems.

In the almost sure knowledge that the earth never experienced a runaway greenhouse even with ancient CO2 levels 10 to 20 times greater than today, these anti-science scoundrels insist with a «high level of confidence» that this amplification is real and it's based on nothing more than faster than expected surface temperature rise in the past few decades which can be TOTALLY explained by multi-decadal cyclic behavior in ocean currents, trade winds, and / or solar magnetic activity causing small global average albedo changes.
