The Methods: Photochemical modeling by a Caltech team indicates that ethane, a hydrocarbon detected on Titan by both of the Voyager spacecraft and the European Infrared Space Observatory, is created when solar ultraviolet light breaks down methane, a minor component of Titan's nitrogen - rich atmosphere, into a stew of organic molecules that form a dense orange - brown smog.

Current climate change models indicate temperatures will increase as long as humans continue to emit greenhouse gases into the atmosphere, but the projections of future precipitation are far less certain.

The model also indicated that the impactor was first compressed by the increasing resistance of the earth's atmosphere.

On Proxima Centauri b, the model indicates that high stellar wind pressure would cause the atmosphere to escape and prevent atmosphere from lasting long enough to give rise to surface - based life as we know it.

Contrary to current geophysical models, ground data indicate that iron meteorites with masses of the order of tens of tons can penetrate the atmosphere without substantial fragmentation.

«Again, this indicates the real atmosphere is less sensitive to CO2 than what has been forecast by climate models.

«We indicated 23 years ago — in our 1994 Nature article — that climate models had the atmosphere's sensitivity to CO2 much too high,» said Christy, the lead author in the study, which has been accepted for publication in the 2017 fourth quarter edition of the Asia - Pacific Journal of Atmospheric Sciences and is available online.

Though this is still a subject of active scientific research, current computer models of the atmosphere indicate that hurricanes are more likely to become less frequent on a global basis, though the hurricanes that do form may be more intense.

My model indicates that about 7 % of carbon released today will still be in the atmosphere in 100,000 years [7].

«We indicated 23 years ago — in our 1994 Nature article — that climate models had the atmosphere's sensitivity to CO2 much too high,» Christy said in a statement.

Their results indicate that the radiocarbon input to the atmosphere from soils and vegetation was 2 to 3 times higher than predicted by their ecosystem model.

Your statement is misleading because the IPCC 2007 report specifically shows model's indicating that GHG's is expected to promote warming in tropical atmosphere (the «hot spot»).

With respect to hurricane intensity, there are observed trends indicating this and model results predicting this, and while there are problems in each (data problems with hurricanes, coarse resolution in global models, etc.), theoretical arguments also make clear that there will be more energy and water vapor available in the atmosphere to cause more intense hurricanes, so a very strong case can be made for this happening.

We'd driving the models with the GHG concentrations, and using carbon cycle models within the climate models to simulate the natural carbon fluxes (atmosphere - land and atmosphere - ocean), which themselves are affected by the simulated climate change, and the residual needed to balance the carbon budget then indicates the anthropogenic emissions that would give the prescribed scenario of CO2 rise.

Despite this significant model shortcoming affecting all climate models, more empirical evidence is being accumulated by both satellites and climate experts that indicate clouds have a much greater impact on temperatures than CO2 levels in the atmosphere than previously understood.

The AMO during the Little Ice Age was characterized by a quasi-periodicity of about 20 years, while the during the Medieval Warm Period the AMO oscillated with a period of about 45 to 65 years... The observed intermittency of these modes over the last 4000 years supports the view that these are internal ocean - atmosphere modes, with little or no external forcing... However, the geographic variability of these periodicities indicated by ice core data is not captured in model simulations.»

Billions of tons of carbon trapped in high - latitude permafrost may be released into the atmosphere by the end of this century as the Earth's climate changes, further accelerating global warming, a new computer modeling study indicates.

«Climate science» as it is used by warmists implies adherence to a set of beliefs: (1) Increasing greenhouse gas concentrations will warm the Earth's surface and atmosphere; (2) Human production of CO2 is producing significant increases in CO2 concentration; (3) The rate of rise of temperature in the 20th and 21st centuries is unprecedented compared to the rates of change of temperature in the previous two millennia and this can only be due to rising greenhouse gas concentrations; (4) The climate of the 19th century was ideal and may be taken as a standard to compare against any current climate; (5) global climate models, while still not perfect, are good enough to indicate that continued use of fossil fuels at projected rates in the 21st century will cause the CO2 concentration to rise to a high level by 2100 (possibly 700 to 900 ppm); (6) The global average temperature under this condition will rise more than 3 °C from the late 19th century ideal; (7) The negative impact on humanity of such a rise will be enormous; (8) The only alternative to such a disaster is to immediately and sharply reduce CO2 emissions (reducing emissions in 2050 by 80 % compared to today's rate) and continue further reductions after 2050; (9) Even with such draconian CO2 reductions, the CO2 concentration is likely to reach at least 450 to 500 ppm by 2100 resulting in significant damage to humanity; (10) Such reductions in CO2 emissions are technically feasible and economically affordable while providing adequate energy to a growing world population that is increasingly industrializing.

With increased loading of greenhouse gases in the atmosphere through the 21st century, the models show an accelerated warming in the Southern Ocean, and indicate that anthropogenic forcing exceeds natural internal variability.

The more complex explanation is even more sobering — carbon cycle models indicate that ~ 25 percent of CO2 from fossil fuel combustion will remain in the atmosphere for thousands of years, and ~ 7 percent longer than one hundred thousand years.

Though this is still a subject of active scientific research, current computer models of the atmosphere indicate that hurricanes are more likely to become less frequent on a global basis, though the hurricanes that do form may be more intense.

(http://blackjay.net/?p=335)(2) The «Bomb Test Curve» of declining 14C in the atmosphere indicates that CO2 has a half - time in the atmosphere of only 10 years, not the hundreds of years of the Bern Model used in numerical climate models.

The increasing acidification of the oceans is another line of evidence indicating the overloading of the atmosphere with CO2, evidence independent of any computer modeling.

-- First we increase the greenhouse gases — then that causes warming in the atmosphere and oceans — as the oceans warm up, they evaporate more H2O — more moisture in the air means more precipitation (rain, snow)-- the southern hemisphere is essentially lots of water and a really big ice cube in the middle called Antarctica — land ice is different than sea ice — climate models indicated that more snowfall would cause increases in the frozen H2O — climate models indicated that there would be initial increases in sea ice extent — observations confirm the indications and expectations that precipitation is increasing, calving rates are accelerating and sea ice extent is increasing.

Climate models indicate that greenhouse gases such as carbon dioxide and methane may enhance the transport of air from the lower atmosphere up into the stratosphere.

And this brings me to my third point: models based on this research indicate that if we continue adding greenhouse gases to the atmosphere as we have, we will eventually face drastic changes in the climate.

However, all models indicate that the ice extent should decrease as greenhouse gases in the atmosphere increase further later in this century.
