Sentences with phrase «emissions over the coming century»

Not exact matches

Meanwhile, a team of climate scientists who have been calculating how the pledges to cut emissions translate into temperature rises over the coming century, and were waiting for the final text to update their models, were left baffled.

Therefore, emissions reductions choices made today matter in determining impacts experienced not just over the next few decades, but in the coming centuries and millennia.

For policy - makers, the speed of climate change over the coming decades matters as much as the total long - term change, since this rate of change will determine whether human societies and natural ecosystems will be able to adapt fast enough to survive.New results indicate a warming rate of about 2.5 C per century over the coming decades (assuming no attempt is made to reduce GHG emissions).

Choices regarding emissions of other warming agents, such as methane, black carbon on ice / snow, and aerosols, can affect global warming over coming decades but have little effect on longer - term warming of the Earth over centuries and millennia.

Therefore, emission reduction choices made today matter in determining impacts experienced not just over the next few decades, but in the coming centuries and millennia.

WASHINGTON — Choices made now about carbon dioxide emissions reductions will affect climate change impacts experienced not just over the next few decades but also in coming centuries and millennia, says a new report from the National Research Council.

July 16, 2010 — Choices made now about carbon dioxide emissions reductions will affect climate change impacts experienced not just over the next few decades but also in coming centuries and millennia, says a new report from the National Research Council.

Drought is expected to occur 20 - 40 percent more often in most of Australia over the coming decades.6, 18 If our heat - trapping emissions continue to rise at high rates, 19 more severe droughts are projected for eastern Australia in the first half of this century.6, 17 And droughts may occur up to 40 percent more often in southeast Australia by 2070.2 Unless we act now to curb global warming emissions, most regions of the country are expected to suffer exceptionally low soil moisture at almost double the frequency that they do now.3 Studies suggest that climate change is helping to weaken the trade winds over the Pacific Ocean, with the potential to change rainfall patterns in the region, including Australia.20, 21,16,22

Second, we investigate whether the cumulative emissions metric still holds for a class of emission pathways that do not assume that all emissions can be mitigated over the coming centuries.

At the same time, if emissions reductions are too modest over the coming two decades, it may no longer be possible to reach a goal of 450 ppm CO2eq by the end of the century without large ‐ scale deployment of carbon dioxide removal technologies.

However, if CO2 emissions aren't drastically reduced temperatures will get a lot warmer over the coming centuries and even millennia than during the previous interglacial.

«Choices made now about carbon dioxide emissions reductions will affect climate change impacts experienced not just over the next few decades but also in coming centuries and millennia... Because CO2 in the atmosphere is long lived, it can effectively lock the Earth and future generations into a range of impacts, some of which could become very severe.»

Revelle calculated that, at the emissions - rates of the time (assuming, like most of his predecessors, that these would likely remain constant), an increase of atmospheric carbon dioxide levels of around 40 % was possible over the coming centuries.

Emissions reductions decisions made today matter in determining impacts experienced not just over the next few decades, but in the coming centuries and millennia.
