What are the causes of global cooling?

well, scientists and meteorologists theorise that because of global warming, the ocean's waters are getting warmer and causing more hurricanes and tropical storms to spawn. also, the earth is the warmest it's been in over 2000 years. all you need to know, WE BEAT THE RECORD! :P

There are the reason for that-\n1-High transpiration rate renders tree leaves cool.\n2-High moisture niche near trees,evaporation renders cooling effect.\n3-Wind passing through leaves becomes less warmer.\n4-Green plants not only absorb a significant portion of the sunlight to invest as energy in photosynthesis to produce sugar resulting into fall in temperature.

No.  If the planet were on a cooling trend, and stayed that way for a while, it might be heading towards a periodic Ice Age, as it has done in the past.  We would consume a lot more of outr limited energy resources just to keep ourselves warm.  Also, don't worry so much about Global Warming.  As I said before, nature goes through these cycles of warming and cooling.  Yes. humans have an impact, but it is small.

Hi! Global warming causes COLD weather because it makes the ice to melt. Then, the oceanic current slows down, since it's a difference of salt and "sweet" water that makes it run. So, if "sweet" water from the melted ice comes into the current, it's less salty, so it will stop to function. If the current stops, then the continents get colder, because the current is that kept them warm. I hope this helps! Daniel from Romania (sorry for my bad writing skills, but I hope you understand)

it is a little of both. yes the earth has heated but weather goes in circular movement. so there are periods of time when the earth heats up and then cools down. yes we are polluting the air and are loosing ozone, but the biggest factor is from methane gas produced by farm animals. we (Christians) are suppose to be good Stewart's of Gods gifts to us. so we need to learn to recycle, conserve and use the planet wisely. one of the things that would help the most is just planting trees. have an cooling effect on earth.

global warming is cause by greenhouse gases being trapped near earths atmosphere, which causes heat to be trapped nearer to earths surface which increases the temperature on earth slightly which melts the polar ice caps which makes water levels rise which means islands will be flooded and shores will advance into the land making living space smaller in an already overpopulated world.

The previous answer is incorrect that there is no relation between the two problems. UNEP reports that global climate change may be slowing the healing process of the ozone layer. Warming of the atmosphere near the earth's surface actually causes cooling of the stratosphere and the cooler temperatures accelerate the chemical reactions that destroy ozone molecules.  Further, the US EPA reports that increased levels of ultraviolet-B radiation can be expected to worsen global warming by reduction of plant and phytoplankton populations. The two problems are tied in complex ways that involve feedback from both systems affecting the other. \nHere is the US EPA booklet:\nhttp://www.epa.gov/ORD/WebPubs/stratoz.pdf\n\nThe UN formed the UN Framework Convention on Climate Change that resulted in the controversial Kyoto Protocol in 1997.  The UN has an excellent website that gives details on the history, the text of the protocol, some of the science, and status. \nhttp://unfccc.int/2860.php\n\nThe UN is also involved in trying to solve ozone depletion. In 1987 the Montreal Protocol was signed by international parties. They agreed to phase out chlorofluorocarbons (CFCs), halons, carbon tetrachloride, and methyl chloroform usage which all cause ozone depletion in the atmosphere. These chemicals are used in dry cleaning, fire extinguishers, and in refrigeration. Many of these chemicals had begun phase out in the United States prior to the protocol due to EPA regulations. The UN's World Meteoroligal Organization and UNEP sponsor assessments of the ozone hole regularly. \n\n\n\nWhile the Montreal Protocol produced positive results during the late 1990's the problem has recently gotten worse- and then improved again!. Here is a NOAA graph showing that:\nhttp://www.cpc.ncep.noaa.gov/products/stratosphere/sbuv2to/gif_files/ozone_hole_plot.png\n\nThe US EPA has an impressive list of links to ozone depletion information. \nhttp://www.epa.gov/ozone/science/#specinfo

There are always different feedbacks in the system, positive and negative. At some point, too large of an increase in temperature triggers a strong negative feedback mechanism, so it won't get extremely hot. In earth, one simple feedback mechanism is through short wave reflection: as it is hotter, there is more evaporation, more clouds, more short wave is reflected back to space, leaving less on earth. With less radiation it gets colder.\nOther, more significant negative feedback mechanisms work on longer timescales. A very discussed one (though not firmly established) regards the thermohaline circulation that ecycles water from the deep ocean. Currently, the gulf stream warms Europe and the North Atlantic because it sinks near Greenland and Labrador. However if it gets too warm, excess river discharge and precipitation at high latitudes decrease the water salinity there, so that the water no longer sinks and the whole circulation stops. With no gulf stream, a large part of the world cools. This process is believed to be the responsible for the triggering of ice ages in the past.

Changes in temperature caused by the expansion (cooling) or compression (warming) of a body of air as it rises or descends in the atmosphere, with no exchange of heat with the surrounding air.

the green house effect is one of the cause of global worming. the global worming means the increase of temp of the earth, the green house effect is the traping of heat by the green house gasses like co2 H2S CFC

Newton's law of cooling deviates when there is a large temperature difference between the body and the surrounding (about 30 + degrees) .

The ozone layer protects the earth from ultraviolet radiation from the sun.  Some does (and is supposed to) get through in order to keep us from freezing.  But too much UV radiation heats the earth more than necessary (and causes sunburns.  Global warming is caused by greenhouse gases (Carbon dioxide being the most prevalent) which trap the heat inside the atmosphere, causing the earth to get warmer and warmer.

Natural warming/cooling of the earth as it progresses through it's life cycle.  Effects of civilization on global warming may be measurable, but it is hardly signifigant when compared to the forces of nature and the tendency of our planet's temperature to fluctuate through ice ages and periods of warmer climes.

Air masses are formed by uneven heating and cooling of the Earth by the sun. This causes pressure differences in different areas of the globe. The movement of air masses is just the flow of high pressure air masses to low pressure areas.

Saw an interesting program on this on the Science channel recently.  Basically scientists think it was because of a mega volcano that erupted that cause the first stage of the extintion.  Then world wide temperature rised 5 degrees and the methane in the bottom of the ocean evaporated and contributed to a super global warming and that raised the Earth's temperature another 5 degrees.  That was the most devastating extintion the planet saw and most of life on Earth and the Ocean died.

hun.. this is a geology question  \n\n\nclimate change... temperature, co2 levels. \nmany dinasoars were to specialized and could not adapt to the new enviroments\nchange in water levels of world... can be due to temperature \nchange in temperature can lead to more extreem weather conditions of floods and draught\nmore precipitation can change salinity changes of oceans \nAsteroid\ndisease\nVolcanic eruptions.. poison gases into atmosphere.. hence the \nCo2 hypothesis\nCo2 (carbon dioxide) is also a greenhouse gas trapping heat
