Increased cooling means increased consumption of electrical power and therefore higher emissions of greenhouse gases into the atmosphere, driving global warming even faster.

«Sparing tracts of land as natural habitat is much better for the vast majority of species than a halfway house of lower - yielding but «wildlife - friendly» farming, and we have recently shown that in the UK land spared through high - yield farming could even sequester enough greenhouse gases to mitigate the UK's agricultural emissions *,» said Balmford.

Within that range of atmospheric density, even higher concentrations of carbon dioxide wouldn't have been adequate to counteract the faint young sun, suggesting that methane, ethane or other strong greenhouse gases kept Earth from freezing.

I have seen some brief mention in biology texts to climate change, including the role of greenhouse gases, but I don't know whether there are more extensive descriptions in texts relevant to middle school and even more particularly, high school.

The next failure to compromise came in the fight over adding a «safety valve» provision to limit unanticipated high costs from greenhouse gas restrictions, something Joe Romm and many others rejected out of hand at the time, even though Romm last year (around minute 37 in this videotaped panel discussion) noted the need for pragmatism to get things started: «The game changer for the world isn't between no price for carbon and a high price.

However, it looks as though there may have been irreparable damage done to the planet and that greenhouse gases will stay anomalously high for decades, even centuries, after we stop emitting greenhouse gases.

One reason for being confident about there being much more uncertaintly than the 97 % concensus suggests is that there is nothing like a concensus, let alone proof, of what caused (and causes) the extreme natural variations in climate throughout geological time.This variation is well documented and almost certainly has a variety of underlying causes which are likely to be very different from C02 or other MM emissions even if higher greenhouse gases levels have often been present.

Because it has been scientifically well established that there is a great risk of catastrophic harm from human - induced change (even though it is acknowledged that there are remaining uncertainties about timing and magnitude of climate change impacts), no high - emitting nation, sub-national government, organization, business, or individual of greenhouse gases may use some remaining scientific uncertainty about climate change impacts as an excuse for not reducing its emissions to its fair share of safe global greenhouse gas emission on the basis of scientific uncertainty.

Scientists caution that even though the world is warming over time, with the amount of heat - trapping greenhouse gas concentrations in the atmosphere now unsettlingly ensconced at the highest level in human history, every year is not expected to set a new record.

Both wetland drying and the increased frequency of warm dry summers and associated thunderstorms have led to more large fires in the last ten years than in any decade since record - keeping began in the 1940s.9 In Alaskan tundra, which was too cold and wet to support extensive fires for approximately the last 5,000 years, 105 a single large fire in 2007 released as much carbon to the atmosphere as had been absorbed by the entire circumpolar Arctic tundra during the previous quarter - century.106 Even if climate warming were curtailed by reducing heat - trapping gas (also known as greenhouse gas) emissions (as in the B1 scenario), the annual area burned in Alaska is projected to double by mid-century and to triple by the end of the century, 107 thus fostering increased emissions of heat - trapping gases, higher temperatures, and increased fires.

Very high confidence that ecological changes will cause Alaska to become a source of greenhouse gases to the atmosphere, even though evidence that Alaska is currently a carbon source is only suggestive.

«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.

Renewable energy can be used to replace some higher - carbon sources of energy in the power grid and achieve a reduction in total greenhouse gas emissions from power generation, even if not used to provide baseload power.

Climate hard - liners in developing countries have long argued that keeping global temperatures to a 2 degree C rise over pre-industrial levels was simply too hot, and would risk unleashing many of the worst destabilizing impacts of global warming — including perhaps the triggering of cascading effects and warming amplifications within nature, such as the melting of Arctic permafrost, that could release more greenhouse gases and push temperatures even higher.

High emissions: If greenhouse gas emissions keep growing, however, sea - level rise gets even more drastic.

But it was cold this winter and C02 is plant food and only a trace gas and the greenhouse effect has been disproved anyway and even if the greenhouse effect does exist, C02 has negligible impact compared to water vapour and our only source of heat is the sun so it must be the sun, unless it is due to the C02 from volcanoes, but C02 follows warming so it can't be the C02 and the medieval warm period was warmer anyway and all the temperature reconstructions that show this not to be true are produced by corrupt scientists being paid by corrupt governments that have colluded to create an excuse to form a one world unelected social - ist government and even if the scientists are not that corrupt, although the e-mails prove they are, they have still got it wrong as the climate sensitivity is not as high as they think it is because it is basically the planets orbits and cosmic rays so we can say for a fact that the warming that probably does not exist is definatley not due to humans and even if it was the evidence is not sufficient to make drastic changes to the economy and increase taxes so that the politicians and scientists and business leaders get rich and leave us all poor — do they think we are stupid or something?
