The evidence for this is a mountain of spectroscopic data about the behaviour of the greenhouse gases from laboratory observations, ground level observations, high altitude aircraft observations and more recently satellite observations.

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.

Now, as an important aside, it is quite doubtful one could actually stabilize at 750 ppm, since work by the National Center for Atmospheric Research and the Hadley Center suggest that carbon cycle feedbacks, like the defrosting of the tundra or the die - back of the Amazon rain forest, would release greenhouse gas emissions that would take the planet to much higher levels.

They found that, as humans burn ever more fossil fuels to release ever higher levels of greenhouse gases into the atmosphere, to stoke yet further global warming and trigger catastrophic climate change, all 571 cities will experience ever greater heatwaves: that is, three consecutive days and nights at which temperatures are about as high as they have ever been for that city.

Total energy - related CO2 emissions for developed countries (Annex I) were only 1.1 % higher than their 1990 level in 2000 and if other greenhouse gases and sinks are counted, these countries could have collectively achieved their goal of returning emissions to 1990 levels.

The cryosphere derives its importance to the climate system from a variety of effects, including its high reflectivity (albedo) for solar radiation, its low thermal conductivity, its large thermal inertia, its potential for affecting ocean circulation (through exchange of freshwater and heat) and atmospheric circulation (through topographic changes), its large potential for affecting sea level (through growth and melt of land ice), and its potential for affecting greenhouse gases (through changes in permafrost)(Chapter 4).

So, for example, if we go through a period of relative higher solar output, and less volcanic activity, relatively less cloudiness, and higher greenhouse gas levels, these would all tend to increase ocean heat content.

The second is the urgency of the need for hard - to - imagine action to dramatically reduce greenhouse gas (ghg) emissions at all scales, that is globally, nationally, and locally, but particularly in high - emitting nations such as the United States in light of the limited amount of ghgs that can be emitted by the entire world before raising atmospheric ghg concentrations to very dangerous levels and in light of the need to fairly allocate ghg emissions reductions obligations around the world.

«Levels of greenhouse gases in the atmosphere reached new highs, and in the northern hemisphere spring 2015 the three - month global average concentration of CO2 crossed the 400 parts per million barrier for the first time.

That is deontological, utilitarian, justice, ecocentric, biocentric, and relationship based ethics would not condone using scientific uncertainty as justification for not reducing high levels of greenhouse gas emissions given what is not in dispute among mainstream climate scientists (See Brown, 2002: 141 - 148).

Carbon dioxide is the biggest long - term human - generated contributor to global warming — other molecules like methane and water vapor are also greenhouse gases, but their levels are more or less constant; the amount of anthropogenic CO2 has been going up steadily for decades and is higher now than in any point in human history.

In addition, because high levels of greenhouse gases are likely to remain in the atmosphere for many years, these changes are expected to last for several decades or longer, according to the U.S. Environmental Protection Agency (EPA).

Even though the rate of emissions of greenhouse gasses slowed down temporarily for some regions of the world, those gasses stay in the air after they are released, so this year greenhouse gas levels reached new record high levels

Modelling from the Met Office in a 2012 report for the Environment Agency suggests that climate change could raise sea levels in the area between 20 and 90 centimetres by the end of the century, and warns that eventual sea level rise could be much higher if greenhouse gas emissions are not cut.

EARLY EARTH Climate puzzle over origins of life on Earth» One explanation for the puzzle was that greenhouse gas levels — one of the regulators of the Earth's climate — were significantly higher during the Archean than they are today.

Most attention in the debate over climate change has been based on the assumption of a gradual increase in mean global temperatures, equilibrating to a new higher level some decades after concentrations of greenhouse gases have stabilized, with effects that will then play out for centuries.

the report argues that up to 86 % of agriculture's potential for climate change mitigation lies in carbon sequestration in soils; that organic farming results in 20 % -28 % higher levels of soil carbon compared to non-organic farming; and that a global conversion to organic farming could sequester up to 11 % of global greenhouse gas emissions.

In light of trends showing a likely 3 °C or more global temperature rise by the end of this century (a figure that could become much higher if all feedback processes, such as changes of sea ice and water vapor, are taken into account) that could result in sea level rises ranging from 20 to 59 cm (again a conservative estimation), Hansen believes it is critical for scientists in the field to speak out about the consequences and rebuke the spin offered by pundits who «have denigrated suggestions that business - as - usual greenhouse gas emissions may cause a sea level rise of the order of meters.»
