How do gases cause global warming?

Question

Any info you can give me on global warming would be great...

Answer 1

Certain gases don't let the heat escape from the Earth's surface -- just like putting on an extra blanket or an extra sweater. If you put on a sweater, the sweater does not actually make any heat. It just makes it so that the heat from your body does not escape as easily.

Greenhouse gases just make it so that the heat from the Earth does not escape as easily. While the sun shines, the Earth absorbs some of the light and heats up as a result. Usually, the heat escapes through the atmosphere out into space. Greenhouse gases prevent the escape of some of this heat. Over time, this may result in the retention of enough heat to cause climate change and some real problems.

The main greenhouse gases are carbon dioxide, water vapor, and methane.

Answer 2

The greenhouse effect is unquestionably real and helps to regulate the temperature of our planet. It is essential for life on Earth and is one of Earth's natural processes. It is the result of heat absorption by certain gases in the atmosphere (called greenhouse gases because they effectively 'trap' heat in the lower atmosphere) and re-radiation downward of some of that heat. Water vapor is the most abundant greenhouse gas, followed by carbon dioxide and other trace gases. Without a natural greenhouse effect, the temperature of the Earth would be about zero degrees F (-18°C) instead of its present 57°F (14°C). So, the concern is not with the fact that we have a greenhouse effect, but whether human activities are leading to an enhancement of the greenhouse effect. Human activity has been increasing the concentration of greenhouse gases in the atmosphere (mostly carbon dioxide from combustion of coal, oil, and gas; plus a few other trace gases). There is no scientific debate on this point. Pre-industrial levels of carbon dioxide (prior to the start of the Industrial Revolution) were about 280 parts per million by volume (ppmv), and current levels are about 370 ppmv. The concentration of CO2 in our atmosphere today, has not been exceeded in the last 420,000 years, and likely not in the last 20 million years. According to the IPCC Special Report on Emission Scenarios (SRES), by the end of the 21st century, we could expect to see carbon dioxide concentrations of anywhere from 490 to 1260 ppm (75-350% above the pre-industrial concentration).

Millions of tons of crap DAILY into the atmosphere is nothing to sneeze at. Pun intended.

We are screwing ourselves over for a buck.
Shooting ourselves in the herd.
Stepping on our own ducks.
Cutting off our nose to spite our finch.
Kicking ourselves in the aardvark.

We're ruining it for everybody and everything, and people who can't accept it are three fries short of a Happy Meal.
Have a nice day.

Answer 4

It is well known that carbon dioxide and particulates tend to absorb sunlight rather than let some it reflect into space. That warms the planet

Global warming is the observed increase in the average temperature of the Earth's atmosphere and oceans in recent decades and its projected continuation into the future.

Global average near-surface atmospheric temperature rose 0.6 ± 0.2 °Celsius (1.1 ± 0.4 °Fahrenheit) in the 20th century. The prevailing scientific opinion on climate change is that "most of the warming observed over the last 50 years is attributable to human activities."[1] The main cause of the human-induced component of warming is the increased atmospheric concentration of greenhouse gases (GHGs) such as carbon dioxide (CO2), which leads to warming of the surface and lower atmosphere by increasing the greenhouse effect. Greenhouse gases are released by activities such as the burning of fossil fuels, land clearing, and agriculture.

Models referenced by the Intergovernmental Panel on Climate Change (IPCC) predict that global temperatures may increase by 1.4 to 5.8 °C (2.5 to 10.5 °F) between 1990 and 2100. The uncertainty in this range results from both the difficulty of predicting the volume of future greenhouse gas emissions and uncertainty about climate sensitivity.

An increase in global temperatures can in turn cause other changes, including a rising sea level and changes in the amount and pattern of precipitation. These changes may increase the frequency and intensity of extreme weather events, such as floods, droughts, heat waves, hurricanes, and tornados. Other consequences include higher or lower agricultural yields, glacier retreat, reduced summer streamflows, species extinctions and increases in the ranges of disease vectors. Warming is expected to affect the number and magnitude of these events; however, it is difficult to connect particular events to global warming. Although most studies focus on the period up to 2100, warming (and sea level rise) is expected to continue past then, since CO2 has a long average atmospheric lifetime.

Remaining scientific uncertainties include the exact degree of climate change expected in the future, and especially how changes will vary from region to region across the globe. A hotly contested political and public debate has yet to be resolved, regarding whether anything should be done, and what could be cost-effectively done to reduce or reverse future warming, or to deal with the expected consequences. Most national governments have signed and ratified the Kyoto Protocol aimed at combatting global warming. (See List of Kyoto Protocol signatories.)

Answer 5

suppossedly, the gases cannot pass through our o-zone into space (gravity and various other elements hold them down) this build-up acts like insulation on the Earth cause the core temperature to slowly increase, melting polar ice caps and causing armeggedon......its all a croc.

Answer 6

dont listen to the hype. the theory and it is a theory is co2 hold heat inside of the planet. heres a question, why did the ice age end?

Answer 7

hahahahahahahaha
