Global Cooling--How does it work?

Question

I know that Global Warming basically is when the sun comes in the Earth and the heat cannot escape do to CO2(carbob dioxide) and some other gases. As a result of the heat, ice melts and some other disasters can occur.

How does global cooling work?

Please explain on a basic level without being to scientific.

Thanks,

Answer 1

One way global cooling can occur is due to the movement of the Earth. The gravity of the other planets in our solar system exert forces on us as well. Depending on their placement, we may be closer or farther away from the sun. These changes in our orbit take 20,000 to 500,000 years to go through a single cycle. It was by studying this cycle, that many were projected a cooling trend for the near future. That is one reason why the warming trend has lots of scientist worrying.

Answer 2

In the short run, changes in ocean currents can bring cold water up from the depths.  Since 3/4 of the earth's surface is covered with water, this can have a temporary effect on global temperatures.  These effect tend to periodically reverse, so their "oscillations" can be seen over time.  

Three identified so far include the El Nino Southern Oscillation (ENSO), the Pacific Decadal Oscillation (PDO) and the Arctic Oscillation (AO).

Unfortunately these act like weather fluctuations, and have no long term effect on the planet's flow of energy in or out, including the physical property of CO2 and other greenhouse gases blocking outgoing heat and causing the earth to warm.  

You can see pauses in our current global warming trend, but you can see that there was no letup in the overall rise in temperatures starting 100+ years ago:

The pauses do appear to coincide with the short term PDO and ENSO influences,

http://jisao.washington.edu/pdo/

but neither can affect the planet's increased tendency to trap more heat as we add greenhouse gases.

For global cooling to occur, the amount of carbon dioxide in the atmosphere must go down.  Full elimination of carbon dioxide from the atmosphere takes hundreds of thousands of years:

"...unlike other greenhouse gases, carbon dioxide does not undergo a simple decline over a single predictable timescale. Instead, the excess carbon is first diluted by the carbon cycle as it mixes into the oceans and biosphere (e.g. plants) over a period of a few hundred years, and then it is slowly removed over hundreds of thousands of years as it is gradually incorporated into carbonate rocks.

The dilution of carbon is such that only 15-30% is expected to remain in the atmosphere after 200 years, with most of the rest being either incorporated into plants or dissolved into the oceans. This leads to a new equilibrium being established; however, the total amount of carbon in the ocean-atmosphere-biosphere system remains elevated."

It is because of this fact, that every bit of carbon that we emit today contributes to a sustained elevated carbon level, that every person on the planet must cooperate to bring our carbon emissions down considerably.

Let me start off by saying we (my family and I) live 100% off of the grid and are completely self-sufficient with a 0% Carbon footprint. I believe this is the first step anyone can make “help the environment”. Once you convert your own life style to a greener more eco friendly route, you can start helping others.

We definitely didn't start global warming, but we definitely do contribute to it now.

Natural gas (or Methane along with other thanes) for example, is completely a natural contributer to global warming and is derived pretty much the same way as oil. ie. Matter (animal, plant etc) decomposes over time resulting in a anaerobic (hope I spelled that right) decay of non-fossil organic material / gas (natural gas or methane).

One problem with global warming is that the concept is so vague in the minds of the people. The critical interpretation is basically how it’s explained in school and the news. However most of the public see global warming connected with the ozone and pollutants which cause harmful greenhouse gasses, etc. therefore investigating and fighting for things like alternative energy (ie. Solar, wind, hydrogen, ethanol, biodiesel, etc)

Greenhouse gases are real and do contribute to global warming. Think of the different gas layers like ozone (o3) that circumference the globe as the clear plastic on a greenhouse. Longer rays of light from the Sun go in and reflect off different thermal masses bouncing back and creating shorter lengths of energy that cannot exist the plastic barrier. These beams then just continue to bounce around inside the green house until they’re finally absorbed completely (some do escape but very few), thereby warming the greenhouse greatly even in cold temperatures.

Basically there are 2 ways that this reaction (or lack of) affects the planet. Global warming and global cooling.

1. as we add to the gases in the stratosphere, where the ozone layer is (Carbon dioxide, carbon monoxide, etc), we add to the plastic of the greenhouse, trapping more short wave length energy and heating the earth more.

2. as we deplete the ozone (with chlorofluorocarbons or CFCs), we allow more long wave length energy, which bounces back out to space without heating any thermal masses on earth, thereby cooling the planet.

It’s pretty easy to see the results..

Melting ice sheets & glaciers

Floods & droughts

Great hurricanes & cyclones

Seasonal extremes

Seasonal phenomena’s

Species extinction

New & resurgent diseases

There are many ways to stop both global warming and cooling from accruing or at least slow them down until we can discover a way to reverse it, but Stop burning fossil fuels is the biggest.

I currently own 2 converted h2 vehicles which run on 100% hydrogen and 1 EV (electric vehicle), not to mention our home is completely off the grid, using alternative energy (solar, wind, etc)

Stop Global Warming!!!

Answer 4

I think anything below 80 degrees temperature is global cooling

Answer 5

There's really no such scientific term as "global cooling".

It often refers to a global warming denier myth claiming that scientists said that the Earth would cool in the 1970s.  That's not really true, it was just a few guys with no data.  They were much like the "skeptics" of today.  More here:

Answer 6

Apparently, if you listen to the GW or AGW crowd.  Or even Al Gore.

Global Warming causes Global Cooling.  Ah, see, it's so simple...  But don't try to think for yourself, because they have all the answers....  Just look back 30 years ago when all the scientists had all the answers....

Indeed. As is the fact that there has been no net warming since 2001. Predictions of environmental doom have been with us for a long time, as the Washington Policy Center reminds us:

•“...civilization will end within 15 or 30 years unless immediate action is taken against problems facing mankind,” biologist George Wald, Harvard University, April 19, 1970.

• By 1995, “...somewhere between 75 and 85 percent of all the species of living animals will be extinct.” Sen. Gaylord Nelson, quoting Dr. S. Dillon Ripley, Look magazine, April 1970.

• Because of increased dust, cloud cover and water vapor “...the planet will cool, the water vapor will fall and freeze, and a new Ice Age will be born,” Newsweek magazine, January 26, 1970.

• The world will be “...eleven degrees colder in the year 2000. This is about twice what it would take to put us into an ice age,” Kenneth Watt, speaking at Swarthmore University, April 19, 1970.

• “We are in an environmental crisis which threatens the survival of this nation, and of the world as a suitable place of human habitation,” biologist Barry Commoner, University of Washington, writing in the journal Environment, April 1970.

• “Man must stop pollution and conserve his resources, not merely to enhance existence but to save the race from the intolerable deteriorations and possible extinction,” The New York Times editorial, April 20, 1970.

• “By 1985, air pollution will have reduced the amount of sunlight reaching earth by one half...” Life magazine, January 1970.

• “Population will inevitably and completely outstrip whatever small increases in food supplies we make,” Paul Ehrlich, interview in Mademoiselle magazine, April 1970.

• “...air pollution...is certainly going to take hundreds of thousands of lives in the next few years alone,” Paul Ehrlich, interview in Mademoiselle magazine, April 1970.

• Ehrlich also predicted that in 1973, 200,000 Americans would die from air pollution, and that by 1980 the life expectancy of Americans would be 42 years.

• “It is already too late to avoid mass starvation,” Earth Day organizer Denis Hayes, The Living Wilderness, Spring 1970.

• “By the year 2000...the entire world, with the exception of Western Europe, North America and Australia, will be in famine,” Peter Gunter, North Texas State University, The Living Wilderness, Spring 1970.

Global warming theory has been around for a while; I learned it as a college student in about 1970. But it didn't get much traction then because the Earth was in a deep freeze. Some years later, environmental hysteria focused on global warming rather than cooling because, coincidentally, the climate started to warm.

Answer 8

well they need to stop cutting down the rainforest. it messes up the natural balance of things,causing it to get off balance and it heats up.
