Sentences with phrase «other anthropogenic forcings likely»

Greenhouse gases contributed a global mean surface warming likely to be between 0.5 °C and 1.3 °C over the period 1951 — 2010, with the contributions from other anthropogenic forcings likely to be between — 0.6 °C and 0.1 °C, from natural forcings likely to be between — 0.1 °C and 0.1 °C, and from internal variability likely to be between — 0.1 °C and 0.1 °C.

AR5: 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 concentrations and other anthropogenic forcings together.

Some of them are optimal fingerprint detection studies (estimating the magnitude of fingerprints for different external forcing factors in observations, and determining how likely such patterns could have occurred in observations by chance, and how likely they could be confused with climate response to other influences, using a statistically optimal metric), some of them use simpler methods, such as comparisons between data and climate model simulations with and without greenhouse gas increases / anthropogenic forcing, and some are even based only on observations.

Multi-signal detection and attribution analyses, which quantify the contributions of different natural and anthropogenic forcings to observed changes, show that greenhouse gas forcing alone during the past half century would likely have resulted in greater than the observed warming if there had not been an offsetting cooling effect from aerosol and other forcings.

In 2013, the Intergovernmental Panel on Climate Change Fifth Assessment Report stated a clear expert consensus that: «It is extremely likely [defined as 95 - 100 % certainty] that more than half of the observed increase in global average surface temperature from 1951 to 2010 was caused by the anthropogenic [human - caused] increase in greenhouse gas concentrations and other anthropogenic forcings together.»

• Greenhouse gases contributed a global mean surface warming likely to be in the range of 0.5 °C to 1.3 °C over the period 1951 to 2010, with the contributions from other anthropogenic forcings, including the cooling effect of aerosols, likely to be in the range of − 0.6 °C to 0.1 °C.

Greenhouse gases contributed a global mean surface warming likely to be in the range of 0.5 °C to 1.3 °C over the period 1951 − 2010, with the contributions from other anthropogenic forcings, including the cooling effect of aerosols, likely to be in the range of − 0.6 °C to 0.1 °C.

This backs up the IPCC attribution statement «It is extremely likely [95 percent confidence] 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 concentrations and other anthropogenic forcings together.»

Again IPCC attribution statement: «It is extremely likely [95 percent confidence] 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 concentrations and other anthropogenic forcings together.»

«It is extremely likely -LCB- 95 % + certainty -RCB- 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 concentrations and other anthropogenic forcings together.»

It is extremely likely [95 percent confidence] all of the observed increase in global average surface temperature from 1951 to 2010 was caused by the anthropogenic increase in greenhouse gas concentrations and other anthropogenic forcings together.

It also follows using the same semantics that: «It is more likely than not that more than the entire observed increase in global average surface temperature from 1951 to 2010 was caused by the anthropogenic increase in greenhouse gas concentrations and other anthropogenic forcings together.»

The phrase «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 concentrations and other anthropogenic forcings together.»

Over at RealClimate, on this topic they claim» 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 concentrations and other anthropogenic forcings together.

So when IPCC tells me that all anthropogenic forcing components other than CO2 (aerosols, albedo, land use, other GHGs, etc.) essentially cancel one another out, I have to accept this as likely to be correct.

The IPCC says (in the AR5 SPM), «It is extremely likely [defined as 95 - 100 % certainty] that more than half of the observed increase in global average surface temperature from 1951 to 2010 was caused by the anthropogenic [human - caused] increase in greenhouse gas concentrations and other anthropogenic forcings together.»

A possible prolonged lull in solar irradiance, if it transpires, would likely partially ameliorate any anticipated warming from anthropogenic greenhouse gases or other forcings.

«Given our understanding of both the climate system as embodied in the current range of models, and the known forcings both natural and anthropogenic, it is very likely that not more than half of the observed increase in global average temperatures since the mid-20th century is due to causes other than the observed increase in anthropogenic greenhouse gas concentrations.»
