Sentences with phrase «total warming»

There is a solid scientific basis for concluding that humanity should be working as hard as possible to keep total warming under 2 °C.

In any case, the IPCC makes clear that 750 ppm would result in total warming from preindustrial levels of 4 °C by 2100.

If we take strong actions to limit further emissions starting today — what the authors call the AS [alternative scenario]-- we can limit total warming from preindustrial levels to about 2 °C, but even that risks sea level rise of one meter per century.

So what matters most as far as total warming is the ultimate stabilized level of CO2.

Presumably recognizing that the world scientific community uses global climate models of some complexity to translate emissions scenarios into projections for warming by specific dates, he refers to «one very credible model» that «suggests we could» hit total warming from pre-industrial levels of about 5.5 °C by 2100.

The disintegration of the Greenland and Antarctic ice sheets is speeding up, providing more evidence we are headed for the worst - case scenario of sea level rise — three to six feet (or more) by 2100 — unless total warming is limited to «well below 2 °C,» as Paris envisions.

Unfortunately using global average surface air temperatures as a measure of total warming ignores the fact that most of the heat (more than 93 %) goes into our oceans, which continue to warm without any sign of a pause, as you can see below.

We need greater attention on the strength of uncertain processes and feedbacks in the physical climate system (e.g. carbon cycle feedbacks, ice sheet dynamics)(NRC 2013), as well as on institutional and behavioral feedbacks associated with energy production and consumption, to determine scientifically plausible bounds on total warming and the overall behavior of the climate system (Heal and Millner 2014).

To calculate total warming and cooling potentials, the total effect of aerosols and greenhouse gases (GHG's) needs to be calculated.

Halving 1990 levels of global greenhouse gas emissions by mid-century, which keeps total warming from preindustrial levels as close as possible to the «safe» level of 2 °C.

As part of a concerted effort to avoid catastrophic climate change, the world unanimously committed to an ongoing effort of increasingly deeper emissions reductions aimed at keeping total warming «to well below 2 °C [3.6 °F] above preindustrial levels.»

Solomon also explained that due to lags inherent in the Earth's climate, climate changes observed as greenhouse gas emissions increase («transient climate change») reflect only about half of the eventual total warming («equilibrium climate change») that would occur for stabilization at the same concentrations.

That is a big number, given that the Paris climate agreement aims to keep total warming to less than 2 °C.

That figure comes from scientists» estimate of the total warming expected from the non-carbon dioxide factors, which comes to about 0.4 degrees Celsius by the end of this century.

Therefore, the solar forcing combined with the anthropogenic CO2 forcing and other minor forcings (such as decreased volcanic activity) can account for the 0.4 °C warming in the early 20th century, with the solar forcing accounting for about 40 % of the total warming.

From 1992 to 2003, the decadal ocean heat content changes (blue), along with the contributions from melting glaciers, ice sheets, and sea ice and small contributions from land and atmosphere warming, suggest a total warming (red) for the planet of 0.6 ± 0.2 W / m2 (95 % error bars).

After 2000, observations from the top of the atmosphere (9)(black, referenced to the 2000 values) increasingly diverge from the observed total warming (red).
