Sentences with phrase «emissions over the next century»

The existence of a strong and positive water - vapor feedback means that projected business - as - usual greenhouse gas emissions over the next century are virtually guaranteed to produce warming of several degrees Celsius.

Not exact matches

If we stay on our current emission pathway, this will change: The metro region will likely see 2 to 7 extremely hot days on average over the next 5 to 25 years, 4 to 17 such days likely by mid-century, and 11 to 59 days — nearly two months — over 95 °F likely by the end of the century.

He also said the United States should provide emissions credits and tax cuts to industries that reduce emissions early, make binding pledges to reduce its own greenhouse gas emissions early in the next century, and give a $ 5 billion boost over the next 5 years to research and development aimed at using energy more efficiently.

BOULDER — Drastic, economy - changing cuts to greenhouse gas emissions will spare the planet half the trauma expected over the next century as the Earth warms.

Rising CO2 emissions, and the increasing acidity of seawater over the next century, has the potential to devastate some marine ecosystems, a food resource on which we rely, and so careful monitoring of changes in ocean acidity is crucial.

but of course we'll be able to control the planet's temperature fluctuations and inconvenient excesses, and precisely guide geohistorical climatic trends over the next decades and centuries by regulating our co2 emissions.

«Thus, while research on climate change should continue, now is the time for individuals and governments to act to limit the consequences of greenhouse gas emissions on the Earth's climate over the next century and well beyond.»

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.

These compounds remain in the atmosphere only days to decades — versus centuries for the CO2 perturbation — so cutting their emissions can appreciably slow the rate of warming over the next several decades.

Thus a grand solar minimum would have to cause about 1 °C cooling, plus it would have to offset the continued human - caused global warming between 1 and 5 °C by 2100, depending on how our greenhouse gas emissions change over the next century.

A new grand solar minimum would not trigger another LIA; in fact, the maximum 0.3 °C cooling would barely make a dent in the human - caused global warming over the next century, likely between 1 and 5 °C, depending on how much we manage to reduce our fossil fuel consumption and greenhouse gas emissions.

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.

The study found these legacy effects could cause some forests to take up 1.6 metric gigatons less carbon over the next century — a quarter of the carbon emissions the U.S. churns out each year — and Anderegg cautions, «that number is almost certainly very low.»

Under the IPCC Business As Usual emissions scenario, an average rate of global mean sea level rise of about 6 cm per decade over the next century (with an uncertainty range of 3 — 10 cm per decade).

The change in P * — E * over the next century, as modeled by 23 state - of - the - art climate models forced with continued greenhouse gas emissions throughout the century, is substantial in many regions.

IPCC has made temperature projections for the end of this century based on continued human GHG emissions (principally CO2) over the next several decades.

Still, it suggested that «over the next decades, renewable forms of energy can gradually become competitive,» and it projected that «CO2 emissions could peak at about 10 gigatonnes of carbon (GtC) a year before the middle of the next century and decline.»

Ultimately, the science says we all need to peak globally over the next 10 years and then sharply reduce emissions to the point where we get to climate neutrality by the second half of the century.

For example, decision makers already have a good idea what will happen if no action to reduce CO2 emissions is taken: the «business as usual» scenario shows significant increases in temperature and changes in precipitation, leading to serious impacts over the next century.

Here, we argue that the twentieth and twenty - first centuries, a period during which the overwhelming majority of human - caused carbon emissions are likely to occur, need to be placed into a long - term context that includes the past 20 millennia, when the last Ice Age ended and human civilization developed, and the next ten millennia, over which time the projected impacts of anthropogenic climate change will grow and persist.

«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.»

If we do nothing to reduce our emissions of greenhouse gases, future warming will likely be at least two degrees Celsius over the next century.

The world can reduce global GHG emissions over the next half century if it wants to.

Because all 2013 Intergovernmental Panel on Climate Change scenarios — except Representative Concentration Pathway 2.6 (RCP2.6), which leads to the total radiative forcing of greenhouse gases of 2.6 W m − 2 in 2100 — imply that cumulative carbon emission will exceed 1,000 Gt in the twenty - first century, our results suggest that anthropogenic interference will make the initiation of the next ice age impossible over a time period comparable to the duration of previous glacial cycles.»

And scientists say that unless we curb global - warming emissions, average U.S. temperatures could increase by up to 10 degrees Fahrenheit over the next century.

So these two articles are suggesting that a grand solar minimum could have a net cooling effect in the ballpark of 1 to 6 °C, depending on how human greenhouse gas emissions change over the next century.

So, in order to trigger another LIA, a new grand solar minimum would have to cause about 1 °C cooling, plus it would have to offset the continued human - caused global warming of 1 to 5 °C by 2100, depending on how our greenhouse gas emissions change over the next century.
