Sentences with phrase «simulating past climate change»

«It is of paramount importance to account for changes in Saharan vegetation and dust emissions when simulating past climate change.

I agree with your statement about other models being too young to judge on the same merit, but I do see value in models being able to retroactively simulate past climate changes.

Not exact matches

Over the past several years, scientists from many institutions have explored the ability of SP - CAM to simulate tropical weather systems, the day - night changes of precipitation, the Asian and African monsoons, cloud - aerosol interactions and other climate phenomena.

Climate models, run on powerful computers which use decades of past and present climate data to simulate how climate will behave, or has in the past, are the most accurate and reliable source of information on potential future climate Climate models, run on powerful computers which use decades of past and present climate data to simulate how climate will behave, or has in the past, are the most accurate and reliable source of information on potential future climate climate data to simulate how climate will behave, or has in the past, are the most accurate and reliable source of information on potential future climate climate will behave, or has in the past, are the most accurate and reliable source of information on potential future climate climate change.

We can not rule out the possibility that some of the low - frequency Pacific variability was a forced response to variable solar intensity and changing teleconnections to higher latitudes that are not simulated by the models, or that non-climatic processes have influenced the proxies... the paleodata - model mismatch supports the possibility that unforced, low - frequency internal climate variability (that is difficult for models to simulate) was responsible for at least some of the global temperature change of the past millennium.»

In most cases, these range from about 2 to 4.5 C per doubled CO2 within the context of our current climate — with a most likely value between 2 and 3 C. On the other hand, chapter 9 describes attempts ranging far back into paleoclimatology to relate forcings to temperature change, sometimes directly (with all the attendant uncertainties), and more often by adjusting model parameters to determine the climate sensitivity ranges that allow the models to best simulate data from the past — e.g., the Last Glacial Maximum (LGM).

It's telling that no physics - based climate model has been developed that can simulate past and recent climate changes without a substantial warming effect from an increase in greenhouse gas concentrations.

Modeled regional and global climate responses to simulated (107, 110, 111) and reconstructed historical land cover changes over the past century (112) and millennium (113) generally agree that anthropogenic deforestation drives biogeophysical cooling at higher latitudes and warming in low latitudes and suggest that biogeochemical impacts tend to exceed biogeophysical effects (113).

Models help us interpret past and present climate changes, and, in so far as they succeed in simulating past changes, they provide a tool to help evaluate the impacts of alternative policies that affect climate.

Through research, GFDL scientists have concluded that it is premature to attribute past changes in hurricane activity to greenhouse warming, although simulated hurricanes tend to be more intense in a warmer climate.

It turns out, models have simulated over four times as much warming compared to reality since 1998, according to a recent study in the journal Nature Climate Change, entitled: «Overestimated global warming over the past 20 years.»
