Not exact matches

The current rate of burning fossil fuels adds about 2 ppm per year to the atmosphere, so that getting from the current level to 1000 ppm would take about 300 years — and 1000 ppm is still less than what most plants would prefer, and much less than either the nasa or the Navy limit for human beings.

If the production rate of C - 14 in the atmosphere was less in the past, dates given using the carbon - 14 method would incorrectly assume that more had decayed out of a specimen than what actually occurred, and would result in faulty data.

They found that water vapour and chlorine and bromine from vaporised sea salts would destroy ozone high in Earth's atmosphere at a much faster rate than it is naturally created (Earth and Planetary Science Letters, DOI: 10.1016 / j.epsl.2010.08.036).

This is partly due to the current atmosphere containing much less CO2 — approximately 400 ppm (parts per million)-- compared to before the PETM, where the concentration was about 1,000 ppm and partly because we emit carbon into the atmosphere at a much faster rate than during the PETM.

The rate at which carbon emissions warmed Earth's climate almost 56 million years ago resembles modern, human - caused global warming much more than previously believed, but involved two pulses of carbon to the atmosphere, University of Utah researchers and their colleagues found.

The rate of carbon release during the PETM was determined to be much smaller than the current input of carbon to the atmosphere from human activities.

That's greater than the warming rate of either the ocean or the atmosphere, and it can have profound effects, the scientists say.

On the long term (longer than a few decades) the transient methane concentration is determined by the chronic rate of methane emission to the atmosphere.

New data from the Pluto flyby of the New Horizons spacecraft showed that nitrogen is escaping from the dwarf planet and into space at a much lower rate than expected due to a cooling effect in the atmosphere.

The study found that the rate of increase of pCO2 in coral reef waters is increasing faster than in the atmosphere, likely due to other human - caused impacts on water quality, with higher values during the wet seasons.

The coastal ecosystems of mangroves, seagrass meadows and tidal marshes mitigate climate change by sequestering carbon dioxide (CO2) from the atmosphere and oceans at significantly higher rates, per unit area, than terrestrial forests (Figure 1).

As long as there is more carbon dioxide in the atmosphere than before, it will reduce the percentage of thermal radiation which is able to leave the atmosphere, which means that the climate system must heat up if the rate at which energy leaves the climate system is to equal the rate an which energy enters the climate system.

Now, if you have all this very cold, nearly freezing water surrounding these ice caps, sucking up carbon dioxide out of the polar atmosphere, at nearly the highest possible rate, 30 times faster than oxygen, and 70 times faster than nitrogen, doesn't it stand to reason that the air that remains might just have a lot less carbon dioxide in it than the atmosphere across the rest of the planet?

On the long term (longer than a few decades) the transient methane concentration is determined by the chronic rate of methane emission to the atmosphere.

Climate change is quite possibly the most important thing humans have ever done — I mean, we're altering our planet's atmosphere perhaps at a faster rate than at any point in Earth's entire history.

Unfortunately, I believe that the rest of the world on average will have higher methane leakage rates from the hydrofracking and transmission operations than for those in the USA; which I believe, will significantly increase methane concentrations in the atmosphere over the next several decades.

If this occurs, we will start to see an acceleration in the increase in concentration of CO2 and it could even start to rise at a rate greater than the amount we ourselves are directly adding to the atmosphere.

Temperature tends to respond so that, depending on optical properties, LW emission will tend to reduce the vertical differential heating by cooling warmer parts more than cooler parts (for the surface and atmosphere); also (not significant within the atmosphere and ocean in general, but significant at the interface betwen the surface and the air, and also significant (in part due to the small heat fluxes involved, viscosity in the crust and somewhat in the mantle (where there are thick boundary layers with superadiabatic lapse rates) and thermal conductivity of the core) in parts of the Earth's interior) temperature changes will cause conduction / diffusion of heat that partly balances the differential heating.

@ 48 If your speculation is correct, I assume that another consequence would be that, if / when concentrations of greenhouse gases start to drop, corresponding reductions in surface ocean / land temperatures would take place at a much slower rate than would otherwise be the case: the surplus heat stored in the deep ocean will gradually make its way to the ocean surface, and continue to warm the atmosphere for decades, if not longer.

At the point where there is so much H2O vapor in the atmosphere that there is very little solar heating of the surface (very very far from happenning), there will also tend to be almost no net LW cooling at the surface, so a tropospheric - type lapse rate could still tend to extend down to the surface (as long as the net LW cooling is smaller than the SW heating, there will be some non-radiative flux from the surface for equilibrium conditions).

Under this scenario, most of the clathrate deposits in the arctic (both tundra and shallow continental shelf deposits) could be released into the atmosphere in a fairly short period of time (less than a century), implying a rate of outgassing that makes 100 times present estimated levels a vast underforecast.

3 claims that the GHG human emission rate is approximately 2 times larger than the observed rate during the last decades, so if the Sun drives a little bit the CO2 and CH4 cycle mechanisms (which in this case are absorbing large amount of CO2 and CH4 from the atmosphere) it might leave a signal in the CO2 and CH4 record as well.

Actually, the concentration goes up somewhat faster than a constant times the emission rate, because the lifetime in the atmosphere gets longer (IPCC TAR).

Current HCV rates of carbon emission into the atmosphere is estimated to be 100 - 150 greater than even those massive PETM eruptions 55 million years ago.

CO2 levels in the atmosphere are increasing at much faster rates than any time in the last 600,000 years.

Since the source of anthropogenic global warming is ostensibly increasing concentration of CO2 in the atmosphere, it makes no sense to posit that over time the oceans will warm at a faster rate than the atmosphere above them.

me warming of the earth's temperature, but that the observed rate of warming (both at the earth's surface and throughout the lower atmosphere) is considerably less than has been anticipated by the collection of climate models upon whose projections climate alarm (i.e., justification for strict restrictions on the use of fossil fuels) is built.

There is not the slightest influence of any natural cycle, as long as the inflows are equal to the outflows, which is nearly the case: the variation in net sink rate (0.5 - 3.5 GtC) over a year is less than the increase measured in the atmosphere...

The current rate of burning fossil fuels adds about 2 ppm per year to the atmosphere, so that getting from the current level to 1000 ppm would take about 300 years — and 1000 ppm is still less than what most plants would prefer, and much less than either the nasa or the Navy limit for human beings.»

This makes sense because it takes time to equilibrate an excess of CO2 in the atmosphere with the ocean, and the shallow ocean responds faster than intermediate or deep water, so the ratio of the land to marine signals is therefore proportional to the carbon emissions rate.

What's lost in a lot of the discussion about human - caused climate change is not that the sum of human activities is leading to some warming of the earth's temperature, but that the observed rate of warming (both at the earth's surface and throughout the lower atmosphere) is considerably less than has been anticipated by the collection of climate models upon whose projections climate alarm (i.e., justification for strict restrictions on the use of fossil fuels) is built.

Rainfall from resolved rather than parameterized processes better represents the present ‐ day and climate change response of moderate rates in the community atmosphere model.

By measuring changes in winds, rather than relying upon problematic temperature measurements, Robert J. Allen and Steven C. Sherwood of the Department of Geology and Geophysics at Yale estimated the atmospheric temperatures near 10 km in the Tropics rose about 0.65 degrees Celsius per decade since 1970 — probably the fastest warming rate anywhere in Earth's atmosphere.

The lower atmosphere is mixed sufficiently so that air warms and cools at a rate of about 5 degrees F / 1000 feet, or slightly less steep than the dry adiabatic lapse rate (of 5.4 degrees F / 1000 feet).

They report that stopping deforestation and allowing young secondary forests to grow back could establish a «forest sink» — an area that absorbs carbon dioxide rather than releasing it into the atmosphere — which by 2100 could grow by over 100 billion metric tons of carbon, about ten times the current annual rate of global fossil fuel emissions.

Heated by condensation on the rise, the descending dry air would adiabatically heat up at 9.8 deg C per 1000 meters and so that it would rapidly become warmer than surrounding atmosphere having a standard lapse rate of 6.5 deg C per 1000 meters.

Actually, the atmosphere doesn't even delay cooling at the surface overnight either — we found that the surface temperature dropped ten times more than if it simply cooled at a direct rate without delay in cooling, and so therefore, it is not delaying cooling at the surface at all, but enhancing it.

Yes it can: if in one year all land vegetation on earth burns down or 1000 volcanoes emit 1000 times more than today in one year, the increase in the atmosphere will increase the sinks far beyond the «normal» exchange rate.

As a result of the build - up of heat - trapping greenhouse gases in the atmosphere — due to our burning of fossil fuels, cutting down trees and other activities — global average temperature is now changing at a faster rate than at least over the past 1,000 years.

In the real world, things are more complicated, as indeed some inflows are increasing or decreasing, due to the increase in the atmosphere, but the main point is that decay rate and exchange rate have nothing to do with each other, and that the 14C tracer shows more the exchange rate than the decay rate.

If the actual lapse rate of the atmosphere is less than the DALR, then the atmosphere is stable and convective mixing does not occur unless there is external forcing (like a hot sun).

Yet on all datasets, the atmosphere is warming at less than half the rate originally predicted by their fellow - activists at the error - prone Intergovernmental Panel on Climate Change — who have a vested interest in overstating the supposed extent of our influence on climate.
