«This quantitative attribution of human and natural climate influences on the IPWP expansion increases our confidence in the understanding of the causes of past changes as well as for projections of future changes under further greenhouse warming,» commented Seung - Ki Min, a professor with POSTECH's School of Environmental Science and Engineering.

It is this background warming from the heat trapped by greenhouse gases that actually accounts for most of the predictability in future temperature change, said Michael Mann, a climate scientist at Penn State.

Since this goes along with an increasing greenhouse effect and a further global warming, a better understanding of the carbon cycle is of great importance for all future climate change predictions.

The same lessons apply for the future — raise greenhouse gases and the climate will warm substantially.

And looking further in the future, other researchers see greenhouse - driven warming becoming a big and harmful influence in that populous region: «A statistically predictive model for future monsoon failure in India.»

If, for example, scientists had somehow underestimated the climate change between Medieval times and the Little Ice Age, or other natural climate changes, without corresponding errors in the estimated size of the causes of the changes, that would suggest stronger amplifying feedbacks and larger future warming from rising greenhouse gases than originally estimated.

«Future projections based on theory and high - resolution dynamical models consistently suggest that greenhouse warming will cause the globally averaged intensity of tropical cyclones to shift towards stronger storms,» Knutson et al. (2010); Grinsted et al. (2013) projected «a twofold to sevenfold increase in the frequency of Katrina magnitude events for a 1 °C rise in global temperature.»

Quantification of the likely contributions of greenhouse gases and other forcing factors to past temperature change (Section 9.4.1.4) in turn provides observational constraints on the transient climate response, which determines the rapidity and strength of a global temperature response to external forcing (see Glossary and Sections 9.6.2.3 and 8.6.2.1 for detailed definitions) and therefore helps to constrain likely future rates of warming.

Heartland's spokesperson frequently say there is no scientific consensus that most of the global warming of the twentieth century was man - made, or that scientists are able to predict future climate conditions, or, finally, that there is a basis in science or economics for passing laws that would reduce greenhouse gas emissions.

First, the computer climate models on which predictions of rapid warming from enhanced atmospheric greenhouse gas concentration are based «run hot,» simulating two to three times the warming actually observed over relevant periods — during which non-anthropogenic causes probably accounted for some and could have accounted for all the observed warming — and therefore provide no rational basis for predicting future GAT.

This warming was obviously caused by Californian Indians ripping around in SUVs and motorcycles spewing dangerous greenhouse gases with no thought for the future.

... In light of their recent findings, Davies et al. say there is «little support for the existence of a «permanent El Niño»... that there was robust ENSO variability in past «greenhouse» episodes and that future warming will be unlikely to promote a permanent El Niño state,» which point they also emphasize in the final sentence of their abstract, where they say that their evidence for robust Late Cretaceous ENSO variability «does not support the theory of a «permanent El Niño,»» [Andrew Davies, Alan E.S. Kemp, Graham P. Weedon, John A. Barron 2012: Geology]

In September 2006, the Houston Chronicle quoted White saying: «We need to make sure that power plants built for today have minimal emissions and contributions to global warming, the greenhouse gases, where we will see increasing regulation in this country, and in other countries, in the future.»

Because nations have failed to make commitments to reduce global greenhouse gas emissions to levels that will limit future warming do 2 °C, there is an increasing sense of urgency among climate scientists around the world on the need for all nations to significantly increase their greenhouse gas emissions reductions commitments to their fair share of safe global emissions.

Manabe and Stouffer (1993) pioneered the demonstration of a transition under future warming; an improved model showed a shutdown was especially likely with rapid increase of greenhouse gas emissions, Stocker and Schnitter (1997); see also Broecker (1997); Wood et al. (1999); summary: Rahmstorf (1999); Ganopolski and Rahmstorf (2001) for instability during a glacial period; IPCC (2001a), pp. 439 - 40.

-LSB-...] Future warming of the climate is inevitable for many years due to the greenhouse gases already added to the atmosphere and the heat that has been taken up by the oceans.

A fortuitous future cooling of this amount, due to the Sun, would not fully compensate for the effects of increases in greenhouse gases, which are projected to warm the Earth by 1 to 3 °.

The class assignment was to identify the year for each spot on the globe in which all future years were, according to climate model projections, warmer as a result of greenhouse gas emissions than the warmest year simulated by the models during the historical period 1860 to 2005.

> Scientists probably did not adequately convey to the public that their projections for future warming are based on models that account only for the so - called «forced response» in global mean surface temperatures — that is, the change caused by greenhouse - gas emissions.

The elements are: (1) the amount of temperaturechange since 1850; (2) whether the change is in the range of natural variability or is attributable to humans; (3) the amount of warming that greenhouse gases (CO2 and equivalents) will warm the Earth in the future; and whether for the most likely scenarios, there are more losers than winners and if the change is just different.

Each molecule of carbon dioxide, which is the most important long - lived manmade greenhouse gas, can remain in the atmosphere for as many as 1,000 years, making it more urgent to cut emissions in the near future, or face continued cumulative warming for centuries to come.

By the 1990s, there was a tentative answer: minor solar variations could indeed have been partly responsible for some past fluctuations... but future warming from the rise in greenhouse gases was far outweigh any solar effects.

Dr. David Evans, a former climate modeller for the Australian government's Greenhouse Office, says he found two mathematical errors showing that the IPCC «over-estimated future global warming by as much as 10 times.»

Africa's climate is warmer than it was 100 years ago and model - based projections of future greenhouse gas induced climate change for the continent project that this warming will continue, and in most scenarios, accelerate (Hulme et al. 2001; Christensen et al. 2007).
