Sentences with phrase «term warming projections»

Some recent research, aimed at fine - tuning long - term warming projections by taking this slowdown into account, suggested Earth may be less sensitive to greenhouse gas increases than previously thought.

Also, I am missing a specific statement that acknowledges that the short - term warming projections of TAR (0.15 ° to 0.3 °C per decade) and AR4 (0.2 °C per decade) turned out to be wrong, i.e. there has been no warming since the end of 2000, despite unabated human GHG emissions and atmospheric concentrations reaching record levels.

Not exact matches

The long - term warming over the 21st century, however, is strongly influenced by the future rate of emissions, and the projections cover a wide variety of scenarios, ranging from very rapid to more modest economic growth and from more to less dependence on fossil fuels.

The IPCC chapter on long - term climate change projections that Wehner was a lead author on concluded that a warming world will cause some areas to be drier and others to see more rainfall, snow, and storms.

«The information will be a critical complement to future long - term projections of sea level rise, which depend on melting ice and warming oceans.»

I guess my main question is: what projections of warming can be accurately assessed for their true accuracy in the short term (next ten years or so)?

Nevertheless it is interesting to consider this alongside, say, Stott and Jones (2012) who showed that constraining the models with recent observations makes the higher end of long - term projections look less likely, although long - term warming is still projected.

-- A line stressing that «the current temperature plateau» does not undercut projections of long - term warming:

The IPCC chapter on long - term climate change projections that Wehner was a lead author on concluded that a warming world will cause some areas to be drier and others to see more rainfall, snow, and storms.

Much of the fear of global warming, now called climate change, stems from long - term projections that use complex climate models.

However, I believe that I have made strong arguments in terms of the importance of natural variability in the attribution of late 20th century warming and in projections of 21st century warming, and in documenting that the IPCC models and arguments are inadequate in this regard.

The current version of the figure gives the impression that the IPCC expected temperature to warm continuously year on year, which of course was not the expectation — the projections shown here are just the long - term trend either from averaging the GCMs or using simple climate models.

«Scientists were quick to declare the results of the Turner et al paper, which covered 1 per cent of the Antarctic continent, did not negate a long - term warming because of man - made climate change... «Climate model projections forced with medium emission scenarios indicate the emergence of a large anthropogenic regional warming signal, comparable in magnitude to the late - 20th - century peninsula warming, during the latter part of the current century,» the Turner research concluded.»

Despite the pause, the long - term projection that the world is likely to warm by about three degrees if the proportion of carbon dioxide in the atmosphere doubles was still on course.
