Global Warming

Global Warming is the century-scale rise in the average temperature of the Earth's surface, oceans, and atmosphere due to an increase in the greenhouse effect. Greenhouse gases such as carbon dioxide from burning fossil fuels or from deforestation trap heat that would otherwise escape from Earth. This warming is causing climate patterns to change.

Asked in Global Warming, Pollution, Climatology and Climate Changes, Green Living

What are the predicted results of global warming?

The United Nations Inter-Governmental Panel for Climate Change (IPCC), 2007: Summary for Policymakers suggests that: Continued greenhouse gas emissions at or above current rates would cause further warming and induce many changes in the global climate system during the 21st century, with warming expected to be greatest over land and at most high northern latitudes, Snow cover is projected to contract. Widespread increases in thaw depth are projected over most permafrost regions. Sea ice is projected to shrink in both the Arctic and...

What are the main greenhouse gases causing global warming?

There are many gases which contribute to global warming. Some have a more potent effect than others. The number after the name indicates the equivalent greenhouse gas effect compared to carbon dioxide (the principal man-made greenhouse gas): Water vapour (H2O) = ? Carbon dioxide (CO2) = 1 Methane (CH4) = 21 Nitrous oxide (N2O) = 298 Sulfur Hexafluoride (SF6) = 22,200 Chlorinated fluorocarbons (CFC's) = 1000 to 9000 Water vapor is an odd one in the list. It contributes to global warming because as the atmosphere...

Asked in Global Warming, Ozone Layer

Does the ozone layer have anything to do with global warming?

No, Global Climate Change has very little to do with the Depletion of the Ozone Layer. Recent global climate change or global warming is now considered by most climate scientists to be the likely result of increases in man-made greenhouse gas concentrations such as carbon Dioxide (CO2) in the atmosphere. These gases absorb strongly in the Infra red part of the electromagnetic spectrum. This has the effect of trapping heat and raising the temperature of the lower atmosphere. The depletion of the ozone (O3)...

Asked in Global Warming, Planet Venus, Air Pollution

What planet is very hot due to its runaway greenhouse effect?

Venus, the second planet from the sun, is covered in clouds and has a very high surface temperature due to its greenhouse effect. Due to an excess amount of carbon dioxide (CO2), its temperature is 460 degrees Celsius or 850 Fahrenheit or 735 Kelvin. It is the hottest planet. It has a very thick atmosphere of Carbon dioxide that is considered a runaway greenhouse effect. Its average surface pressure due to the thick atmosphere is 93 bar, or 93 times that of Earth's. It...

Asked in Global Warming, Antarctica, Climatology and Climate Changes

How is climate change affecting Antarctica?

Antarctica is the coldest place on our planet, far colder than the Arctic, so changes from global warming will be slower to happen and difficult to measure. However, there are changes happening. Ice is melting at the edges and snow is building up in the centre! Warmer air means more moisture in the atmosphere, and this is falling as snow on the centre of the continent. This snow doesn't melt, but builds up as ice. Approximately 100 cubic kilometers (24 cubic miles) of ice...

Asked in Global Warming, Green Living, Al Gore

What does Al Gore say about global warming?

Al Gore says that global warming is happening, we CAN stop it, and we have to stop putting greenhouse gases into the air and conserve energy and resources. Al Gore believes strongly that global warming is a very serious and dangerous effect that man is causing. He is a outspoken leader on our need to curb our greenhouse emissions. His comments and leadership is unquestionably for serious action. In April 2014, speaking at the University of Hawaii, he warned, "the future of civilization...

How many trees are killed a year from pollution?

Thousands, probably millions. It's impossible to say. Pollution happens in many ways, air and water, and some effects take some time. ...

Asked in Global Warming, Fossil Fuels, Fossils

How can fossil fuels harm the environment?

Burning fossil fuels creates pollution and pollution is bad for the environment. they produce harmful greenhouse gasses Burning fossil fuels releases carbon dioxide emissions that add to the greenhouse effect. This is causing global warming and climate change. Fossil Fuels are fuels formed by natural resources. It harms the environment because every time we use it, carbon dioxide goes into the air. A: What is the environmental impact of the extraction, transport and use of fossil fuels? The major fossil fuels we use are oil, natural gas...

What is the importance of green revolution?

The Green Revolution was the notable increase in cereal-grains production in Mexico, India, Pakistan, the Philippines, and other developing countries in the 1960s and 1970s. This trend resulted from the introduction of hybrid strains of wheat, rice, and corn (maize) and the adoption of modern agricultural technologies, including irrigation and heavy doses of chemical fertilizer. The Green Revolution was launched by research establishments in Mexico and the Philippines that were funded by the governments of those nations, international donor organizations, and the U.S. government....

What country has the smallest carbon footprint?

Kiribati, a small island nation in the Pacific Ocean, has the smallest carbon footprint. It is particularly vulnerable to sea-level rise from global warming, and its President signed the Bandos Island declaration on 10 November 2009. This was a promise by Kiribati and nine other countries to show moral leadership and start greening their economies by voluntarily committing to carbon neutrality. ...

What are green house gases?

A greenhouse gas is an atmospheric gas that absorbs and retains energy from infrared radiation. Greenhouse gases must have at least three atoms, to vibrate and turn the radiation into heat. Energy from the sun heats the earth's surface and atmosphere, which drives the earth's weather and climate. The earth's surface radiates some of this solar energy back into space. Certain atmospheric gases are called greenhouse gases (GHGs) because they help trap some of the outgoing energy, retaining heat somewhat like the glass...

Asked in Astronomy, Global Warming

Could we install giant mirrors in space between earth and sun to divert sunlight?

This might be possible, but before we go to the enormous challenge and expense of doing that it would be much smarter to develop the ability to use the tremendous amount of solar energy that we already receive. If the point is to overcome global warming, rest assured that we already have several effective and practical methods of dealing with it and reversing it that are far easier and cheaper. But even those are generally unpopular, and are widely resisted and maligned. ...

Asked in Global Warming, Energy Conservation, Light Pollution

Why is it important to reduce reuse and recycle?

Recycling helps the Earth by not producing more waste onto our planet. We are throwing away far too much rubbish. Our landfills are filling up. Many towns and cities have trouble finding new holes to dump rubbish in. All sorts of paper and be recycled and turned into fresh paper and card. This uses far less energy than making new paper from trees. All glass bottles and steel and aluminum cans can be recycled as well as all other metals, again saving energy....

Do plants emit carbon dioxide?

Yes, plants emit carbon dioxide at night and when they die. Plants emit carbon dioxide and they also capture it again. Plants, along with forests and other kind of vegetation and the world's oceans, emit 97% of the global carbon dioxide emissions. But not only do they emit carbon dioxide, they also capture it. This natural process is called the Carbon Cycle. ...

Does watching TV cause global warming?

Home use is responsible for more than half of the total output of carbon dioxide. Appliances (A/C, heat, water heaters) account for 70% of home electricity use, and another 10% by incandescent lighting. Televisions actually account for about 3% of the typical home's energy use. Pinpointing television use as a significant cause of global warming is therefore contraindicated. ...
