Can u give me a paragraph definition of global warming. not the causes or effects, just the basic meaning of?

Question

global warming?

Answer 1

Global warming is a natural phnomena occure in our planet due to human activities.this includes industerial activities.

In fact, Global warming and climat changes are two main factors in causing cyclons to happen.

Answer 2

Global Warming is any increase in average air temperature at the Earth's surface over a period of decades or more.

Answer 3

Humans and nature have put stuff in space-the atmosphere- that causes harm-destroyers the ozone layer and /or heats the planet-but sometimes it cools it. That is where you have to do the study to learn what is going on. Take a geography class. Have fun

Global warming

Global mean surface temperature anomaly 1850 to 2007 relative to 1961–1990



Mean surface temperature anomalies during the period 1995 to 2004 with respect to the average temperatures from 1940 to 1980

Global warming is the increase in the average temperature of the Earth's near-surface air and oceans in recent decades and its projected continuation.

The global average air temperature near the Earth's surface rose 0.74 ± 0.18 °C (1.33 ± 0.32 °F) during the 100 years ending in 2005.[1] The Intergovernmental Panel on Climate Change (IPCC) concludes "most of the observed increase in globally averaged temperatures since the mid-20th century is very likely due to the observed increase in anthropogenic greenhouse gas concentrations"[1] via the greenhouse effect. Natural phenomena such as solar variation combined with volcanoes probably had a small warming effect from pre-industrial times to 1950 and a small cooling effect from 1950 onward.[2][3] These basic conclusions have been endorsed by at least 30 scientific societies and academies of science,[4] including all of the national academies of science of the major industrialized countries.[5][6][7] While individual scientists have voiced disagreement with some findings of the IPCC,[8] the overwhelming majority of scientists working on climate change agree with the IPCC's main conclusions.[9][10]

Climate model projections summarized by the IPCC indicate that average global surface temperature will likely rise a further 1.1 to 6.4 °C (2.0 to 11.5 °F) during the 21st century.[1] The range of values results from the use of differing scenarios of future greenhouse gas emissions as well as models with differing climate sensitivity. Although most studies focus on the period up to 2100, warming and sea level rise are expected to continue for more than a thousand years even if greenhouse gas levels are stabilized. The delay in reaching equilibrium is a result of the large heat capacity of the oceans.[1]

Increasing global temperature will cause sea level to rise, and is expected to increase the intensity of extreme weather events and to change the amount and pattern of precipitation. Other effects of global warming include changes in agricultural yields, trade routes, glacier retreat, species extinctions and increases in the ranges of disease vectors.

Remaining scientific uncertainties include the amount of warming expected in the future, and how warming and related changes will vary from region to region around the globe. Most national governments have signed and ratified the Kyoto Protocol aimed at reducing greenhouse gas emissions, but there is ongoing political and public debate worldwide regarding what, if any, action should be taken to reduce or reverse future warming or to adapt to its expected consequences.

Answer 5

No because just the opposite has been proved.The earth does not heat or cool simultaneously in the two Hemispheres.One side cools the other warms.There are however studies being done to disprove this but no success has been reached.Maybe one day they will actually find a connection but it doesn't seem hopeful.

Answer 6

Global warming is when the average temperature of the planet increases. This is happening because the earth is capturing more of the suns energy than before. The reason that the planet is capturing more of the suns energy is because the earth is radiating less of the suns energy away than before. This is because the makeup of the atmosphere is changing in a way that it insulates better while still allowing sunshine in. Think of a hot car with its windows rolled up versus that same car with its windows rolled down. By adding greenhouse gases to our atmosphere we are effectively rolling up the car windows with the sun shining into the car. It's going to get warmer inside because we aren't letting the heat to escape.

Answer 7

global warming (n.) - a scam designed by margaret thatcher to redistribute wealth to the third world countries, while causing alarm and spreading doomsday nonsense.

Answer 8

Global warming is caused by the greenhouse effect, which is gases which are released into our atmosphere but do not leave it and are bounced back to the earth. These gases heat up our atmosphere and therefore 'warm up' the earth.

Ex an green-house gases is Co2

Answer 9

Global warming is the world wide rise in temperatures compared to the 30 year average temperature from 1961-1990.
