Not exact matches

A controversial prediction that found its way into the most recent report by the Intergovernmental Panel on Climate Change said they'd be gone by 2035, but a detailed new analysis contradicts it.

The study, published today in the Proceedings of the National Academy of Sciences, addresses a longstanding paradox between predictions of widespread extinctions of cold - water species and a general lack of evidence for those extinctions despite decades of recent climate change.

These are the erroneous predictions ascribed to the most recent report from the U.N. Intergovernmental Panel on Climate Change (IPCC)-- a document reviewed by some 2,500 scientists and other experts as well as vetted by more than 190 countries.

These predictions are limited by a poor understanding of the recent changes observed in the Antarctic and Greenland ice sheets, and a lack of knowledge about the variability of ice sheet behaviour under a warming climate.

«In the face of natural variability and complexity, the consequences of change in any single factor, for example greenhouse gas emissions, can not readily be isolated, and prediction becomes difficult... Scientific uncertainties continue to limit our ability to make objective, quantitative determinations regarding the human role in recent climate change, or the degree and consequence of future change.»

Comparing model predictions of GHG - induced warming with recent natural temperature fluctuations also indicates the potential scale of man - made climate change.Early modelling experiments focused on the total long - term change resulting from a doubling of carbon dioxide (CO2) levels.

There has been a recent emphasis in decadal - scale prediction, and also creating a marriage between climate and fields such as synoptic - dynamic meteorology... something relatively new (and a different sort of problem, than say, estimating the boundary condition change in a 2xCO2 world); as Susan Solomon mentioned in her writing, a lot of people have become much more focused on the nature of the «noise» inherent within the climate system, something which also relates to Kevin Trenberth's remarks about tracking Earth's energy budget carefully.

Comparisons to the most recent data consistently finds that climate change is occurring more rapidly and intensely than indicated by IPCC predictions.

The researchers used recent historical data and not climate modeling, so the study does not make any future predictions, but Swain says the findings appear to be consistent with other climate research that reveals there is little change in average precipitation, but an increase in the amount of very wet or very dry periods.

In fact, Eilperin breathlessly reports the new report «highlights the extent to which recent scientific assessments have outstripped the predictions issued by the Nobel Prize - winning U.N. Intergovernmental Panel on Climate Change in 2007.»

Past IPCC predictions regarding climate change and global warming have become an international joke in recent years.

Issues like the Medieval warm period, different possible causes of climate change (such as solar activity, or even the nature of our climate), studies indicating the last interglacial period was warmer than today, and the failure of recent dire predictions about the climate all show the debate on climate change is not nearly as settled as many global warming proponents would have us believe.

The simulations also produce an average increase of 2.0 °C in twenty - first century global temperature, demonstrating that recent observational trends are not sufficient to discount predictions of substantial climate change and its significant and widespread impacts.

Aerosol impacts remain a source of major uncertainty in climate prediction in the Intergovernmental Panel on Climate Change (IPCC) 4th Assessment Report (2007).5 Recent and ongoing missions and instruments providing aerosol information include TOMS (1979 --RRB-, AVHRR (1979 --RRB-, MODIS (1999 --RRB-, MISR (1999 --RRB-, POLDER (2002 --RRB-, (A) ATSR (1991 --RRB-, PARASOL (2006 --RRB-, SCIAMACHY (2003 --RRB-, CALIPSO (2006 --RRB-, GLAS (2003 --RRB-, OMI (2004 --RRB-, and AIRS (2002 climate prediction in the Intergovernmental Panel on Climate Change (IPCC) 4th Assessment Report (2007).5 Recent and ongoing missions and instruments providing aerosol information include TOMS (1979 --RRB-, AVHRR (1979 --RRB-, MODIS (1999 --RRB-, MISR (1999 --RRB-, POLDER (2002 --RRB-, (A) ATSR (1991 --RRB-, PARASOL (2006 --RRB-, SCIAMACHY (2003 --RRB-, CALIPSO (2006 --RRB-, GLAS (2003 --RRB-, OMI (2004 --RRB-, and AIRS (2002 Climate Change (IPCC) 4th Assessment Report (2007).5 Recent and ongoing missions and instruments providing aerosol information include TOMS (1979 --RRB-, AVHRR (1979 --RRB-, MODIS (1999 --RRB-, MISR (1999 --RRB-, POLDER (2002 --RRB-, (A) ATSR (1991 --RRB-, PARASOL (2006 --RRB-, SCIAMACHY (2003 --RRB-, CALIPSO (2006 --RRB-, GLAS (2003 --RRB-, OMI (2004 --RRB-, and AIRS (2002 --RRB-.

More usefully in terms of future predictions, a recent paper in PNAS by Van Vuuren and co-workers (including a friend of mine, Tom Wigley, who is an Adjunct Professor at the University of Adelaide), assessed the impact on climate change of some plausible real - world actions.
