Sentences with phrase «average warming contributions»

C'm on, let's be honest here - > you simply can not definitively attribute global average warming contributions with that kind of accuracy.

Not exact matches

So the report notes that the current «pause» in new global average temperature records since 1998 — a year that saw the second strongest El Nino on record and shattered warming records — does not reflect the long - term trend and may be explained by the oceans absorbing the majority of the extra heat trapped by greenhouse gases as well as the cooling contributions of volcanic eruptions.

With the contribution of such record warmth at year's end and with 10 months of the year record warm for their respective months, including the last 8 (January was second warmest for January and April was third warmest), the average global temperature across land and ocean surface areas for 2015 was 0.90 °C (1.62 °F) above the 20th century average of 13.9 °C (57.0 °F), beating the previous record warmth of 2014 by 0.16 °C (0.29 °F).

Reductions in emissions from deforestation, in particular in the Amazon, have made a major contribution to global efforts to control global warming; since 2005 the Amazon has seen its deforestation rate drop 77 % below the historic average.

Since the CMIP5 models used by the IPCC on average adequately reproduce observed global warming in the last two and a half decades of the 20th century without any contribution from multidecadal ocean variability, it follows that those models (whose mean TCR is slightly over 1.8 °C) must be substantially too sensitive.

Item 8 could be confusing in having so many messages: «It is extremely likely that more than half of the observed increase in global average surface temperature from 1951 to 2010 was caused by the anthropogenic increase in greenhouse gas... The best estimate of the human - induced contribution to warming is similar to the observed warming over this period....

As he pointed out, a dominant unforced contribution to surface warming relative to forced trends would be expected to be accompanied by a trend of declining OHC, which is inconsistent with the observed trends averaged over the past half century as evidenced by mixed layer temperature measurements and sea level rise.

It's as if the contributions to global average temperature are roughly half and half between long natural cycles and man - made global warming, such that during periods when the natural cycles are warming, we get quick, alarming warming.

And yet, the average Chinese still consumes less than 20 percent of the energy consumed by the average American, meaning that the Chinese contribution to global warming is going to grow tremendously.

Nationally Determined Contributions (NDCs), as laid out in Article 3 and 4 of the Paris Agreement, require developed countries signatory to the agreement to communicate «ambitious efforts» to achieve the purpose of the Paris Agreement (keeping average global warming below 1.5 / well below 2 degrees celsius).

We recently discussed this subject during our dialogue with Dr. Pielke Sr., and showed that using the CO2 radiative forcing estimate of Skeie et al. (2011) and the Padilla et al. (2011) 90 % confidence range for the transient climate sensitivity parameter, we can estimate a CO2 contribution of 0.64 to 1.28 °C, with a best estimate of 0.79 °C warming of average global surface temperature over the past ~ 150 years.
