Sentences with phrase «although global heat»

Not exact matches

The authors note that more than 85 % of the global heat uptake (Q) has gone into the oceans, including increasing the heat content of the deeper oceans, although their model only accounts for the upper 700 meters.

Global average surface temperatures are not expected to change significantly although temperatures at higher latitudes may be expected to decrease to a modest extent because of a reduction in the efficiency of meridional heat transport (offsetting the additional warming anticipated for this environment caused by the build - up of greenhouse gases).

Global heat doesn't (AFAIK) include shortwave, although I'll admit that's a technicality.

Although this century kicked off with the hottest decade on record, 2010 was the hottest year and in 2011 the Arctic may have broken both the summer and the winter melting record, there has still been heat missing: the rise in global temperatures is smaller than what one would expect from the rise in greenhouse gas concentrations, which — despite UNFCCC attempts to tackle climate change since Kyoto 1997 and Copenhagen 2009 — has even accelerated.

Renewable energy is making impressive gains in the electricity sector, although these are not being matched in transportation and heating — which together account for 80 % of global energy consumption.

Although he doesn't actually come out and say it, Evans suggests that the global warming trend in the surface temperature record is an artifact caused by the urban heat island (UHI) effect:

Likewise, although most of today's average global temperature has been driven by heat ventilating from the Arctic Ocean, as visualized in this NASA graphic, Arctic temperatures were also far warmer during most of the Holocene.

Fire looks to be one big contributor to global warming — not directly through its heat, although in some barely discernable way that certainly adds to warmth, but by what it does to the planet's landscape.

Over the past century, that makes the sea 1.6 degrees hotter — a greater heating than the accepted global average of about 1.1 degrees C (although that number doesn't account for the masking effect of pollution).

Maximum temperature is a better metric (although as the appropriate metric to diagnose global warming, ocean heat content change should be used).

Although temperature is not a measurement of «heat» in the climate system, NASA's Goddard Institute for Space Studies (GISS), former directer James Hansen, and the British Hadley Centre for Climate Change, have consistently promoted the use of surface temperature as a metric for global warming.

Although most focus has been centered on carbon dioxide because it is more abundant and thus contributes more to global warming, methane is about 30 percent more powerful than carbon dioxide when it comes to trapping heat.

Although we focus on a hypothesized CR - cloud connection, we note that it is difficult to separate changes in the CR flux from accompanying variations in solar irradiance and the solar wind, for which numerous causal links to climate have also been proposed, including: the influence of UV spectral irradiance on stratospheric heating and dynamic stratosphere - troposphere links (Haigh 1996); UV irradiance and radiative damage to phytoplankton influencing the release of volatile precursor compounds which form sulphate aerosols over ocean environments (Kniveton et al. 2003); an amplification of total solar irradiance (TSI) variations by the addition of energy in cloud - free regions enhancing tropospheric circulation features (Meehl et al. 2008; Roy & Haigh 2010); numerous solar - related influences (including solar wind inputs) to the properties of the global electric circuit (GEC) and associated microphysical cloud changes (Tinsley 2008).

«The overall slow decrease of upwelling SW flux from the mid-1980's until the end of the 1990's and subsequent increase from 2000 onwards appear to caused, primarily, by changes in global cloud cover (although there is a small increase of cloud optical thickness after 2000) and is confirmed by the ERBS measurements... The overall slight rise (relative heating) of global total net flux at TOA between the 1980's and 1990's is confirmed in the tropics by the ERBS measurements and exceeds the estimated climate forcing changes (greenhouse gases and aerosols) for this period.

In the meantime, Levitus et al. have once again reminded us that although the surface warming may have been dampened in recent years, global warming hasn't magically vanished, and that heat stored in the oceans will eventually come back to haunt us.

The toy global circulation models take latent heat flux into account so it isn't missing although one might question the accuracy of the number or how it changes with temperature.

Re 416 Bernd Herd — in climate science, for global climate change, specifically a global (average surface) temperature change in response to a global (typically average net tropopause - level after stratospheric adjustment) radiative forcing (or other heat source — although on Earth those tend not to be so big), where the radiative forcing may be in units of W / m ^ 2, so that equilibrium climate sensitivity is in K * m ^ 2 / W (it is often expressed as K / doubling CO2 as doubling CO2 has a certain amount of radiative forcing for given conditions).

Although natural variations in the solar output can explain most of the temperature variations over the past centuries, it appears that global warming by heat - trapping gases, emitted by human activity, is required to explain the sharp rise in global temperatures during the 1990s.

The article acknowledged «concern» regarding «the connection between hurricanes and global warming,» but noted that although» [t] hat is a subject of a heated debate in the science community,» «Gore cited five recent scientific studies to support his view.»
