Global Warming

It's logical. If the earth is warming, and scientists (and our own experiences) tell us that it is, then one of the effects of a warming atmosphere is that it warms things in the atmosphere. Glaciers are exposed to the air, the air is warmer, and so the glaciers melt. Therefore, global warming is responsible for melting the world's glaciers.

They are not the same. Placing limits on water use is a localised regulation to make sure your town doesn't run out of water. The burning of fossil fuels and the cutting down of trees are the two factors that are causing global warming. A much more serious issue!

The most abundant greenhouse gas is water vapor. Although not as potent as other greenhouse gases pound for pound, by sheer volume water vapor is the key greenhouse gas.

Carbon dioxide is the second largest (by volume) greenhouse gas. Methane and nitrous oxide complete the four primary greenhouse gases, but there are only trace amounts of these in our atmosphere. Since water vapor is about 4% of the atmosphere, and CO2 concentrations are 400 parts per million, 0.04/0.0004 = 1%. In other words, CO2 is roughly 1% of the greenhouse gas.

It depends on which greenhouse gas doubled its concentration.

Water vapour is the most plentiful greenhouse gas, but only remains in the atmosphere for a few days and precipitation will prevent its concentration from doubling.

Carbon dioxide levels have indeed increased by 35 per cent since pre-industrial times and the rate of increase in concentration is growing rapidly, so in the absence of any action at all, would certainly double. The present concentration is just over 380 parts per million (ppm), and doubling this to around 760 ppm would be disastrous. Long before this level was reached, the governments of the world would place our global economy on a war footing and mandate a zero-carbon economy no matter what the pain caused by this. Clearly, we never wish to get to the point that this action became necessary.

Methane levels have also increased since pre-industrial times but the rate of increase in concentration is growing more slowly. The disaster that could result from doubling atmospheric methane concentrations means that it could never be allowed to happen.

If greenhouse gas levels reach the point where there is a 'runaway greenhouse effect' because of positive feedback resulting from higher temperatures, then there will no longer be any action that we can take to prevent its continuance. We would simply have to accept the consequences.

In the atmosphere, heat is distributed through processes like convection, conduction, and radiation, with warm air rising and cool air sinking. In the ocean, heat is distributed mainly through ocean currents, which transport warm and cold water around the globe. These processes play a crucial role in regulating Earth's climate system.

Greenhouse gases absorb infra red radiation (heat) coming back up from the warmed earth. They hold this heat, and in turn warm up the air around them, as well as warming the earth's surface again.

1. Stop using fossil fuels (coal, oil and natural gas)
2. Change to renewable energy for everything (solar, wind, hydro and many others)
3. Stop cutting down forests (deforestation)
4. Plant billions of trees to replace the old forests
5. Spread the word, educate people, make a start in your own home. Whenever we can reduce the use of fossil fueled energy the world is a better place.

Yes, tropical air masses tend to be warmer than polar air masses because they originate in regions closer to the equator where temperatures are higher. Polar air masses, on the other hand, come from regions closer to the poles where temperatures are colder.

Scientists can use wolves as 'indicators' to learn more about global warming by their migration patterns and hunting patterns. Depending on what they hunt and when can tell you more about global warming, because of the limited amounts of certain animals that the wolves eat. Also, you can tell by where they are going, like if prey is short in a certain area, they will move, so scientists know then that something is causing the animals to die or go somewhere else, which is often the effect of global warming. This mostly goes for arctic wolves, because the ice is melting, so their prey is dying off because of the habitat loss.

Chances are, global warming is going to get worse, however, we cannot predict exactly how rapidly this will happen or how bad it will get. My guess is that I will not live to see severe global warming, but the next generation after me probably will.

And severe global warming could be very destructive. The immediate threat is that the ice caps will melt, and the sea level will rise a great deal, causing massive flooding of coastal regions. Many other problems are likely to result as well. Things could get very interesting.

The Earth's population is increasing due to factors like improved healthcare leading to lower mortality rates, higher birth rates in some regions, and overall increased longevity. Additionally, access to better nutrition and sanitation has contributed to population growth.

this means that the polar bears habitat is melting because of global warming and climate change.

the ice is melting because of climate change and global warming this means that polar bears are being extinct.

After the sun sets, land typically cools more rapidly than the ocean or sea. As the land cools, the air close to the surface cools, as well. Since cold air is denser than warm air, the cold air tends to sink and compress. The falling and compressing air creates a void at higher altitudes, and the void is then filled with high-altitude air over the oceans or sea. This, in turn, creates an updraft of air over the water, which creates a void at low altitude over the water. Finally, the air near the land's surface tries to fill the void over the water. This produces on offshore breeze or a land breeze. That is, the wind blows away from land and out to sea. The reverse occurs when the sun rises and heats the land faster than the water.

When a warm air mass moves into an area where a cold air mass is located, it is called a warm front. This interaction typically leads to gradual warming of the air and can result in prolonged periods of precipitation.

Global warming is a local issue because the solution has to start with us as individuals and in our communities. We need to reduce our use of electricity and motor fuel, in order to help reduce the world's carbon dioxide emissions. We can take action by, for example, replacing incandescent light bulbs with high efficiency ones, by turning off appliances when not in use and by using air conditioning and home heating more sparingly.

Global warming is an international issue because all governments must get together to identify and agree on urgent action to change to a carbon-neutral world economy. The time is past for free-riding and asking other countries to reduce their emissions "before" we do.

Global warming is a contributing factor to the increase in frequency and intensity of bushfires. Rising temperatures and changing weather patterns create drier conditions that can fuel the spread of wildfires. However, other factors such as land management practices and human activities also play a role in the occurrence of bushfires.

The burning of fossil fuels releases the carbon dioxide removed from the atmosphere hundreds of millions of years ago.

Other carbon dioxide sources include volcanoes, bush fires, . The decaying of dead plants and animals also releases carbon dioxide and methane. Carbon dioxide is released by cellular respiration in plants (at night) and from all living animals. The production of waste CO2 by microscopic animals in the ocean is a substantial amount.

Burning diesel fuel releases carbon dioxide (CO2), a major greenhouse gas. It also produces smaller amounts of other greenhouse gases such as methane (CH4) and nitrous oxide (N2O). Additionally, diesel combustion can emit particulate matter, which contributes to global warming indirectly.

Trees remove carbon dioxide (CO2), a greenhouse gas, from the atmosphere and store the carbon in their trunks and branches. When deforestation happens and the trees are burnt or rot, that carbon dioxide is added to the atmosphere, and because no more trees are planted, there is no longer anything to remove the CO2. This is how deforestation adds to the greenhouse effect.

Yes, Earth's climate has changed over time due to natural variations in the Earth's orbit, solar activity, and volcanic eruptions. However, the current rate of global warming is unprecedented and mainly driven by human activities, such as the burning of fossil fuels and deforestation, leading to an increase in greenhouse gases in the atmosphere.

Greenhouse gases, especially carbon dioxide (CO2) are absorbed by the ocean. This is turning the oceans acidic (carbonic acid). This damages corals (by bleaching) and makes it difficult for shellfish to grow shells that are as strong as before.
