Sentences with phrase «uncertainty about future warming»

Uncertainty about future warming is not just the uncertainty about sensitivity, but also about the future greenhouse gas levels (GHG).

Not exact matches

As can be seen your graph, our climate models make a wide range of predictions (perhaps 0.5 - 5 degC, a 10-fold uncertainty) about how much «committed warming» will occur in the future under any stabilization scenario, so we don't seem to have a decent understanding of these processes.

From the standpoint of doing something about global warming, the uncertainties are irrelevant unless we don't care what kind of world we leave for future generations - of humans and polar bears.

Another Nobel laureate in economics, Thomas Schelling, wrote recently that «In responding to such uncertainty [about future warming and sea level rises], we should neither wait until the uncertainty has been completely resolved before we take action nor act as if it's certain until we have assurance that there's no danger.»

Uncertainty about the extent of future global warming is in itself an indicator of serious climate change to come, scientists have claimed.

That means there is still a lot of uncertainty about the extent of future warming — estimates of the effect of doubling CO2, including all feedback processes, range from 2 °C to 6 °C.

There is new information that lack of sea ice causes storms to produce larger waves and more coastal erosion.5 An additional contributing factor is that coastal bluffs that were «cemented» by permafrost are beginning to thaw in response to warmer air and ocean waters, and are therefore more vulnerable to erosion.22 Standard defensive adaptation strategies to protect coastal communities from erosion such as use of rock walls, sandbags, and riprap have been largely unsuccessful.23 There remains considerable uncertainty, however, about the spatial patterns of future coastal erosion.

That's because their disagreements are not just about interpretations of scientific data, but about how they assess the risks, amid the uncertainty over global warming's future impact.

There is also scientific uncertainty about the future consequences of global warming.

Uncertainty about the future climatic effect of carbon dioxide emissions consists of two parts: the future carbon dioxide concentration given current levels of emissions, and the amount of warming that can be expected from a given carbon dioxide concentration.
