Sentences with phrase «warm at different rates»

Local heat capacity — Differing surfaces cool and warm at different rates for the same heat flux.

The «radiation only» equilibrium models do not address the other issue that the layers of the surface and atmosphere can warm at different rates because they have a different mix of cooling mechanisms.

The different parts will warm at different rates, but no part will have a temperature lower than the initial temperature.

But that would be a very brave assumption, because different parts of the world's oceans probably warm at different rates due to global warming.

But different parts of the world warm at different rates.

Ocean and land surfaces warm at different rates, and land covered by vegetation absorbs and reflects solar energy differently than do deserts or ice - caps.

Locally, knowing what the global sensitivity to whatever forcing is not too important, as the earth warms at different rates depending on the latitude and partly of the location (combination of the longitude and latidtude).

The difference lies in the absence of water vapour in the descending column which then warms at a different rate to the cooling in ascent.

An advantage of compiling temperature records in this manner is that one could more easily see whether various areas of the globe (northern, southern hemishpere, equatorial or polar) are warming at different rates which would give further insight into wher the warming anthropogenic.

Tamino has pointed out that the change in the distribution of surface temperatures may not be due to increased variability, as Hansen et al. conclude, but rather simply due to a combination of different regions warming at different rates, and when their data are combined, the result looks the same as it would if temperature variability were increasing.

Locally, knowing what the global sensitivity to whatever forcing is not too important, as the earth warms at different rates depending on the latitude and partly of the location (combination of the longitude and latidtude).

Okay, I should be slightly careful here, as the expectation is really that the feedback response is not exactly linear as we double CO2, but this is thought to be because of different regions warming at different rates (polar amplification, for example) than because the response is actually non-linear.

At the same time, increasing depth and duration of drought, along with warmer temperatures enabling the spread of pine beetles has increased the flammability of this forest region — http://www.nature.com/nclimate/journal/v1/n9/full/nclimate1293.html http://www.vancouversun.com/fires+through+tinder+pine+beetle+killed+forests/10047293/story.html Can climate models give different TCR and ECS with different timing / extent of when or how much boreal forest burns, and how the soot generated alters the date of an ice free Arctic Ocean or the rate of Greenland ice melt and its influence on long term dynamics of the AMOC transport of heat?

«The fact remains that the rate of warming in the early 20th century is comparable to that in the late 20th century whether you look at the Arctic in isolation or the globe as a whole and since CO2 levels were markedly different»

The fact remains that the rate of warming in the early 20th century is comparable to that in the late 20th century whether you look at the Arctic in isolation or the globe as a whole and since CO2 levels were markedly different in the 2 periods there must be another significant factor.

While RealClimate has called into question the soundness of the paper's quite narrow conclusions of discrepancy between model predictions and measurements of the relative rate of warming of different levels of the atmosphere over the tropics, this paper is being touted by the deniers as showing that the models are wrong to predict any warming at all, and that predictions of future warming and climate change can be entirely discounted.

One solution which has different assumptions than what is used to define the HadCRUT4 global values, would be to calculate the zonal means first and then area weight those — which assumes that missing data warms at the same rate as the local zonal average as opposed to the global means.

Re my 441 — competing bands — To clarify, the absorption of each band adds to a warming effect of the surface + troposphere; given those temperatures, there are different equilibrium profiles of the stratosphere (and different radiative heating and cooling rates in the troposphere, etc.) for different amounts of absorption at different wavelengths; the bands with absorption «pull» on the temperature profile toward their equilibria; disequilibrium at individual bands is balanced over the whole spectrum (with zero net LW cooling, or net LW cooling that balances convective and solar heating).

Climate models indicate that the Arctic warms at a faster rate than the rest of the planet, and hence it is of interest to compare the warming at the different latitudes (eg.

Yes, and I suppose when they do they will understand you can't ignore a troposphere that isn't warming at the appropriate rate to the surface; you can't ignore a stratosphere that isn't cooling at the appropriate rate per decade; you can't ignore an ocean that isn't warming despite an assumed large energy imbalance; you can't ignore that if you declare a long lag time or a large long term climate sensitivity then previous forcings are subject to the same principles; and you can't ignore that the rate of warming was no different this last time then the time before it and the time before that.

If I understood Armour's paper correctly, he claimed that all feed - backs were close to linear in response to temperature over time, but that different regional warming rates (specifically, slow warming at high latitudes) could make the feed - backs and sensitivity appear to increase with time.

Warming now is occuring at different rates in different places, but the whole planet is wWarming now is occuring at different rates in different places, but the whole planet is warmingwarming.

The authors teased out the effects of climate warming from other factors by looking at eight different systems for rating forest aridity; these included the Palmer Drought Severity Index, the MacArthur Forest Fire Danger Index and the Canadian Forest Fire Danger Rating Srating forest aridity; these included the Palmer Drought Severity Index, the MacArthur Forest Fire Danger Index and the Canadian Forest Fire Danger Rating SRating System.

Under rapid greenhouse warming, the different parts of the planet have warmed at very different rates, leading to the scatter in the zonal anomalies since 1980.

The underlying issue is this: While the planet was subject primarily to natural changes, the different parts of the planet were warming and cooling at similar rates, thus the zonal anomalies run fairly parallel.

It looks likely that the rapid warming of the Arctic has broken the thermometer temperature record in two different ways - firstly by violating the assumption that unobserved regions of the planet warm at a broadly similar rate to observed regions, and secondly by violating the assumption that neighbouring regions of the planet's surface warm at a similar rate.

Lam and team used climate models from the Intergovernmental Panel on Climate Change to examine the economic impacts of climate change on fish stocks and fisheries revenues under two different emissions scenarios: a high - emission scenario, in which the rates at which greenhouse gases are pumped into the Earth's atmosphere continue to rise unchecked, and a low - emission scenario under which ocean warming is kept below two degrees Celsius.

Because that is a proper measure of the change in rate of warming which is different from saying the noughties are warmer; of course they are because we are in a warming period which began in 1850; compared with an anomaly base in the 50's or 60's, succeeding decades will be absolutely warmer but whether they are warming at the same rate is really the test.

The age of melting ice at the different ice caps will be dependent on their slope, aspect and situation, which will affect the amount of ice accumulated during the late Holocene and the melt rate in the current warm period.

If we have measures of volcanic activity, solar activity and greenhouse gas forcing, then it is straightforward assign similar warming rates at different times to the dominating forcing at those times.

However, it means that David's headline «Global warming is just HALF what we said» and standfirst «Leaked report reveals the world is warming at half the rate claimed by IPCC in 2007» are based on a comparison of two different quantities.

Let's have a look at some warming rates for the different indices in Table 2.

As the U.S. corn belt reveals, every regional climate is different - they experience major warming and cooling periods for different reasons, at different times, and at different rates, regardless of the global atmospheric CO2 levels.

From 1993 to 2012, the «global mean surface temperature... rose at a rate of 0.14 ± 0.06 °C per decade,» and the observed warming over the last 15 years of the period was, «not significantly different from zero.»

Quigley: «In contrast, if CO2 increases at a BAU rate, warming will be near 3 °C at century's end, producing a different planet.»

The current warming trend is of particular significance because most of it is extremely likely (greater than 95 percent probability) to be the result of human activity since the mid-20th century and proceeding at a rate that is unprecedented over decades to millennia.1 Earth - orbiting satellites and other technological advances have enabled scientists to see the big picture, collecting many different types of information about our planet and its climate on a global scale.

Obviously, any insulator, between two objects at different temperatures will decrease the rate of energy exchange and slow down the temperature decline of the warmer object.
