How does Biology affect global warming in?

through trees and the process of photosyntesis..\n\nglobal warming occurs because of the excess of certain gases, CO2 and others, in the atmosphere. photosyntesis can help recycle those gases by turning them into oxygen. By cutting down trees there's less ways to get rid of those gases and so they keep accumulating in the atmosphere causing an increase in global warming.\n\nhope that helps

It is certainly true that there have been periods in history that have been hotter than it is now before the rise of the combustion engine and heavy deforestation that ultimately lead to the greenhouse effect. Let me say that the 1.2 degrees Celsius increase that we have observed since the rise of the machine and the human effect on the environment is really insufficient to prove what effect of global warming really is. Additionally, the most abundant greenhouse gas is water vapor (making up about 95% of the abundance of all the greenhouse gases). These two facts basically say that there is no support EXPERIMENTALLY for the theory. Yet the theory is correct: with  a build up of greenhouse gases in all the strata of the atmosphere causes infrared light to reflect several more times off of the earth's surface than it normally would, causing a net increase in thermal energy over long periods of time. I am very much a pro-environment scientist, so I can say without bias that the theory is definitely correct, yet we do not currently know what factors (global warming or something else entirely) we can attribute heat changes to, and therefore, we do not know how much global warming will affect us. Only time will really tell...

I think it would help in your theory,due to more greenhouse gasses would be assimilated by more trees.\n\npart of the problem with global warming is that much of the planets eco systems are being destroyed without being replendished (south america tree harvesting)

The missing link between air pollution and gobal warming is a concept that you've probably heard of before known as the greenhouse effect.  \n\nThe greenhouse effect is caused by an increase in certain pollutants (known as greenhouse gasses) that are released into the atmosphere.  If enough water vapour, carbon dioxide, methane (and other culprits) are present in the atmosphere, it turns the atmosphere into a "greenhouse" in a way.  Short wavelength infra-red radiation that comes from the sun has enough energy to get through the layer of greenhouse gasses and enter our lower atmosphere, but when these rays contact the Earth, they lose some energy.  \n\nAfter they lose energy, they become longer wavelength infra-red rays, which tend not to have enough energy to break back through the layer of gasses.  These rays are absorbed by the greenhouse gasses, then sent back down to the Earth, further heating the planet.\n\nBasically, if you increase the amount of greenhouse gasses in the atmosphere, you let the same amount of heat in, but not as much heat gets out.  The overall temperature of the Earth rises, polar ice caps melt.  Bad stuff happens.\n\nThe best example of this is Venus, which has a thick layer of carbon dioxide (among other things) in its atmosphere.  Thus, the mean temperature of Venus is around 737K, far hotter than Mercury at 440K, even though Mercury is closer to the sun.  \n\nHope this helps.

What About Global Warming . . . . \n\nThe greenhouse effect refers to the fact that Earth is surrounded by an atmosphere which acts like the transparent cover of a greenhouse, allowing sunlight to filter through while trapping heat.\n\nGreenhouse gases are trace gases of mainly water vapor, carbon dioxide, methane, ozone, and nitrous oxide. The Earth's atmosphere largely consists of nitrogen and oxygen, but these gases do not hold heat so they are not greenhouse gases nor contribute to the greenhouse effect.\n\nDuring the day the Earth absorbs heat from the Sun and re-radiates it back out to space. Normally this heat would escape each night and the temperature would fall rapidly. Instead, gaseous molecules absorb the heat given off by the planet, and re-radiate it out in all directions, reabsorbing it, and redistributing it again and again. This keeps the Earth's surface relatively warm and the average temperature comfortable. The greenhouse effect is key in Earth's ability to stay warm and sustain life.\n\nA look to our neighboring planets of Venus and Mars shows what happens when the greenhouse effect - which is akin to a blanket covering the planet - becomes too thick or too thin. Temperatures on Venus soar because of its very thick blanket or atmosphere. The runaway greenhouse effect here is staggering. Mars on the other hand has such a thin blanket (atmosphere) and a weak greenhouse effect, that the planet is very cold. Nearly all of the heat that reaches Mars escapes. Relative distance from the Sun plays a part in the global temperatures of the inner planets, but a greenhouse effect, or lack thereof, is largely responsible for the climates on all these planets.\n\nScientists started using the term "greenhouse effect" in the 1800's. At that time it had no negative connotation. In the mid 1950's the term "greenhouse effect" began to be associated with global warming and also with the negative effects of our industrial age. This enhanced greenhouse effect, as it's sometimes referred to, is the result of burning fossil fuels. This releases additional carbon dioxide into the atmosphere at the rate of about 3 gigatons (3 billion metric tons) per year. Since carbon dioxide (CO2) absorbs heat, we can expect that significant increases in CO2 will tend to raise the global temperature, possibly contributing to global warming. Simply put, if greenhouse gases act like a blanket to keep our planet warm, we are thickening that blanket.\n\nThe natural greenhouse effect on Earth is responsible for life as we know it. We may, however, need to become better stewards of our greenhouse gases in order to preserve life.

In short, Carbon Dioxide, currently being blamed for global warming is the product of burning Carbon based fuels like methane, and also petrolium based fuels.  \n\nCarbon Dioxide (CO2) is also taken out of the air by plants, algae, and bacteria that perform photosynthesis, and is added to a sugar like molecule to produce glucose (a sugar).  The plant or bacteria then uses the glucose for fuel or stores it as starch.  \n\nWe are producing CO2 so fast that plants and algae are not taking it out of the atmosphere as fast as it is being produced.  The extra gas contributes to global warming and climate change.  The excess CO2 also may result in the future in massive increases of photosynthetic algae and bacteria which also could be bad for the oceans, having side effects such as killing all of the fish in the ocean if we are not lucky.

when light radiations enters earths atmosphere then these rays are trapped by carbon dioxide and water molecules present in the atmosphere. moreover earth release absorbed heat radiations at night then carcarbon dioxide and water molecules again absorb the released heat.thus these molecules increase the temperature of earth's atmosphere. this increase in temperature is green house effect.

Global warming is a term used to describe the trend of increases in the average temperature of the Earth's atmosphere and oceans that has been observed in recent decades. The scientific opinion on climate change, as expressed in the UN Intergovernmental Panel on Climate Change (IPCC) Third Assessment Report in 2001 and explicitly endorsed by the national science academies of the G8 nations in 2005, is that the average global temperature has risen 0.6 ± 0.2 °C since the late 19th century, and that it is likely that "most of the warming observed over the last 50 years is attributable to human activities" [1]. The increased volumes of carbon dioxide and other greenhouse gases released by the burning of fossil fuels, land clearing and agriculture, and other human activities, are the primary sources of the human-induced component of warming. The natural greenhouse effect keeps the Earth about 33 °C warmer than it otherwise would be; adding carbon dioxide to a planet's atmosphere, with no other changes, will make that planet's surface warmer.\n\nObservational sensitivity studies [2] [3] and climate models referenced by the IPCC predict that global temperatures may increase by 1.4 to 5.8 °C between 1990 and 2100.\n\nThe range of uncertainty results in large part from not knowing the volume of future carbon dioxide emissions. In addition, there is uncertainty about the accuracy of the underlying climate models.\n\nThe increase in global temperatures is expected to result in other climate changes including rises in sea level and changes in the amount and pattern of precipitation. Such changes may increase the frequency and intensity of extreme weather events such as floods, droughts, heat waves, and hurricanes, change agricultural yields, cause glacier retreat, reduced summer streamflows, or contribute to biological extinctions. Although warming is expected to affect the number and magnitude of these events, it is difficult to connect any particular event to global warming.\n\nAlthough most studies focus on the period up to 2100, warming would be expected to continue past then, since CO2 has a long average atmospheric lifetime [4]. Also, Climate commitment studies indicate that there is a further warming of perhaps 0.5 °C to 1.0 °C — already committed but not yet realised.There are only a few scientists that contest the view that humanity's actions have played a significant role in increasing recent temperatures. However, uncertainties do exist regarding how much climate change should be expected in the future, and a hotly-contested political and public debate exists over what, if anything, should be done to reduce or reverse future warming, and how to cope with the consequences.

Based on basic science, observational sensitivity studies and the climate models referenced by the IPCC, temperatures may increase by 1.4 to 5.8 °C between 1990 and 2100 [2]. This is expected to result in other climate changes including rises in sea level and changes in the amount and pattern of precipitation. Such changes may increase the frequency and intensity of extreme weather events such as floods, droughts, heat waves, and hurricanes, change agricultural yields, cause glacier retreat, reduced summer streamflows, or contribute to biological extinctions. Although warming is expected to affect the number and magnitude of these events, it is difficult to connect any particular event to global warming. Much of the evidence is statistical; a significant increase in certain events which is correlated with warming.

causes: -The climate system varies both through natural, "internal" processes as well as in response to variations in external "forcing" from both human and non-human causes, including solar activity, volcanic emissions, and greenhouse gases. Climatologists agree that the earth has warmed recently. The detailed causes of this change remain an active field of research, but the scientific consensus identifies greenhouse gases as the primary cause of the recent warming. This conclusion can be controversial, especially outside the scientific community.Adding carbon dioxide (CO2) or methane (CH4) to Earth's atmosphere, with no other changes, will make the planet's surface warmer; greenhouse gases create a natural greenhouse effect without which temperatures on Earth would be an estimated 30  °C (54  °F) lower, and the Earth uninhabitable. It is therefore not correct to say that there is a debate between those who "believe in" and "oppose" the theory that adding carbon dioxide or methane to the Earth's atmosphere will, absent any mitigating actions or effects, result in warmer surface temperatures on Earth. Rather, the debate is about what the net effect of the addition of carbon dioxide and methane will be, when allowing for compounding or mitigating factors.Due to the thermal inertia of the earth's oceans and slow responses of other indirect effects, the Earth's current climate is not in equilibrium with the forcing imposed by increased greenhouse gases. Climate commitment studies indicate that, even if greenhouse gases were stabilized at present day levels, a further warming of perhaps 0.5  °C to 1.0  °C (0.9–1.8 °F) would still occur.\neffects: -The predicted effects of global warming are many and various, both for the environment and for human life. These effects include sea level rise, impacts on agriculture, reductions in the ozone layer, increased intensity and frequency of extreme weather events, and the spread of disease. In some cases, the effects may already be being experienced, although it is difficult to attribute specific natural phenomena to long-term global warming. In particular, the relationship between global warming and hurricanes is still being debated. [21] [22] A draft statement by the World Meteorological Organization acknowledges the differing viewpoints on this issue [23].The extent and likelihood of these consequences is a matter of considerable controversy. A summary of possible effects and recent understanding can be found in the report of the IPCC Working Group II [24]. Some scientists believe global warming is already causing death and disease across the world through flooding, environmental destruction, heat waves and other extreme weather events.

Did you mean Global Warming?\nGlobal warming is an increase in the average temperature of the Earth's atmosphere and oceans. The term is also used for the scientific theory of anthropogenic global warming, which attributes much of the recently observed and projected global warming to a human-induced intensification of the greenhouse effect.\n\nFor more info go to http://en.wikipedia.org/wiki/Global_Warming

The greenhouse effect is a natural process in which gases in the upper atmosphere trap heat in the planet.  greenhouse gases is carbon dioxide.  Scientists are concerend about this because carbon dioxide is increasing, therefore intensifying the greenhouse effect.  This can lead to global warming, which might melt the ice caps at the poles and submerge coastal cities in up to 100 meters of water.

Global warming is an increase in the average temperature of the Earth's atmosphere and oceans. The term is also used for the scientific theory of anthropogenic global warming, which attributes much of the recently observed and projected global warming to a human-induced intensification of the greenhouse effect. On this theory, the increased volumes of carbon dioxide and other greenhouse gases released mainly by the burning of fossil fuels, and, to a lesser extent, land clearing and agriculture, are the primary sources of warming. The natural greenhouse effect keeps the Earth 30 °C warmer than it otherwise would be; adding carbon dioxide to an atmosphere, with no other changes, will make a planet's surface warmer. Current research is attempting to find out more details about the processes and factors that would affect a temperature increase especially about positive and negative feedback mechanisms, to allow a more precise quantification of the effects of global warming.\n\nTemperature change is just one aspect of the broader subject of (human-induced) climate change.

Well, the main reason would be that evolution is a process that take thousands, if not millions, of years to accomplish. Also, because evolution works to allow an organism to compete for a resource better than another organism. At this point, we have no competition so the motivation for evolution is basically zero.\n\n I also think that the main issue with global warming isn't going to be humans being unable to survive the temperatures so much as the environment is going to be destroyed so we'll have less animals and plants to eat.

Definitively a lot of hot air goes up warming the atmosphere.\nAlot comes from certain party and politicians in that party. That definitively aids the  warming phenomena which is due to the changing tilt of the earth.\n\nOn the other hand polution cause the opposite effect . it cause solar diming  wich counteracts the global warming effect.So its a War between those with the hot air and those with particle polutants.\n\nAs far as biological life of animals and plant life it does not go back that far .Because it is the changing tilt of the earth(precession of the poles) that cause either global freezing or cooking.I dont think that evolutionary species like revolutionists could survice these extreme changes.\nThe complete poles precession was calculated by scientist and astronomers to have a cycle of 22,000 years.\n\nAs fAR AS DINOSORS ARE CONCERNED ITS NOT SURVIVAL OF THE FITTEST THAT MAKES THEM SURVIVE. it is the availability of nutritional food that allows them to survive. Besides there was a global flood in the history of the Globe. And that was only a short time ago.(poor Noah).So that anihilated some of the  animals who could not reach higher ground.\nThis bring the question whew did the oil in the ground come into being?\n\nAbout millions of years? there were writing that dated before the flood. and these people also exagerated about Time.The same is the case today . Dont believe those scientists who talk out of the top of their hats.Unless there is positive correct proof.
