What is the dominant greenhouse gas in your atmosphere?
Ranking the greenhouse gases in the atmosphere by name and contribution gives us the following table:
Gas /Formula /Contribution(%)
Water vapour /H2O /36 - 72%
Carbon dioxide/CO2 /9 - 26%
Methane / CH4 /4 - 9%
Ozone /O3 /3 - 7%
Of these carbon dioxide and methane have experiences significant changes in their rates of generation by human activities.
The impact of water vapour is very significant and is part of a feedback loop with global warming. As the oceans warm more water vapour is present in the atmosphere and the significance of its impact grows. In the same way the warming air releases more methane from previously contained deposits such as permafrost increasing its impact.
Why are some areas of the world more affected by climate change than others?
Firstly, you should define what you mean by affected and in which respect. The world becomes more and more a global village, hence a drought in a country with high agricultural exports will affect importing countries likewise.
In any case, areas where the climate is already alarming for nature and agricultural production (Sahel, Mediterranean area, Loess plateau China) will experience more problems due to increased droughts, storms. For example in the Mediterranean basin prolonged dry spells increase the sensitivity for fire.
And of course we know about the low-lying areas of the world which will be primarly affected by sea level rise.
What processes on earth are driven by the sun?
Some of the processes on Earth driven by the sun include photosynthesis in plants converting sunlight into energy, the water cycle driven by solar radiation evaporating water, and the heating of the atmosphere which creates wind patterns and weather systems.
Why are water vapor and aerosols important constituents in our atmosphere?
They are both gases whose molecules contain 3 atoms. This means that they can absorb heat. They are greenhouse gases.
They both absorb energy from the earth's surface, thereby heating the atmosphere.
What climatic effects do heat islands have on large cities?
1. Large cities affect local climate by tending increase the warmth. They clear forests and put in heat absorbing concrete and asphalt. They're the physical heat put out by air conditioners and other machinery. Concrete and asphalt in large masses create what is called a heat island effect. This can create a false drought condition because the rain and storm activity will go around the false high.
Is climate change forcing people to migrate and how?
Yes there is a great possibility that is happening due to people's different lifestyles such as:
I don't know how true my answer is or maybe so I wouldn't actually put great emphasis on it as if it were true.
Why does food cause global warming?
Food production contributes to global warming through processes like deforestation, transportation emissions, and methane release from livestock. Clearing land for agriculture reduces carbon sinks, while transportation of food over long distances increases greenhouse gas emissions. Livestock farming, particularly cows, produce methane which is a potent greenhouse gas.
What is the physical and chemical breakdown of rocks?
Im not sure but I do know how mechanical weathering breaks down rocks. By frost action or water going inside the rocks and breaking it apart Gravity an example is a rock falling down a hill for and breaking a part into peaces.
What is the difference in melting a glacier and iceberg?
They are both ice and they may both be melting. But the iceberg is already displacing water, so by melting does little to raise the sea level. When a glacier melts, the additional water does raise the sea level somewhat. This would be particularly true when major ice caps such as the Greenland ice cap, melt.
What is happening now with Climate change?
There are alot of catatrophies happening because 2010 is about to happend. We had alot of earthquakes and earth tilted already. In 2010 earth is supposed to tilt of its axis and alot of bad things happen. But don't get scared they said that earth was going to an end in 2002.
----------------------------
ACTUALLY the predicted date for tilt of the earths axis is 21st December 2012.
And of course this is a theory...
Burning which fossil fuel - coal oil and natural gas - contributes least to global warming?
Burning natural gas contributes least to global warming compared to coal and oil. Natural gas produces fewer greenhouse gas emissions, such as carbon dioxide and methane, per unit of energy generated.
What plants help in weathering of rocks?
Plants like mosses, lichens, and ferns are known to help in the weathering of rocks through a process known as biological weathering. These plants release acids that break down the minerals in rocks, leading to their physical breakdown over time. Additionally, plant roots can grow into cracks in rocks, exerting pressure and causing them to break apart.
The level of water will remain the same because the cork displaces its weight in water, keeping it afloat when the ice melts. When the ice melts, the water that was previously frozen in the ice block will turn into liquid water, maintaining the overall water level.
Is straw a natural or man made material?
Straw is a natural material, typically made from dried grasses such as wheat, rice, or barley. It is a renewable resource that has been used for centuries in various applications, including as a building material, for animal bedding, and as a component in making hats and baskets.
What are the world efforts to fight global warming?
There are many efforts world-wide to reduce the green house gases that are theoretically linked to Global Warming. GW leaders like Al Gore suggest that GW is caused by industrial out pouring of Carbon Dioxide gas.
How much carbon dioxide does a computer produce?
Assuming you mean "how much carbon dioxide is generated by the electricity consumption of a computer", you are actually asking a very complicated question.
In the first instance, you need to know what the energy consumption of your/the average computer is. This depends on a huge number of factors such as: how powerful the processor and graphics cards are, how many hard drives and optical drives it has and what kind of monitor it has and what size that is. Also, the consumption varies depending on whether the computer is under load (performing calculations and reading from or writing to hard drives or optical media). If you're not interested in accuracy, I would guess about 200W for a modest office machine rough average.
Next, it depends on how much CO2 is produced per unit of electricity from your supplier. This in turn depends on what sources are used to provide your energy. Coal and oil produce more CO2 than gas, nuclear and others. The calculation is likely to be very complex and require a lot of research. The answer could be in the region of 500g per KWh, but this could vary wildly depending on which country you are in.
So taking our two assumptions (0.2KW and 500g/KWh), we can very roughly estimate 100g of CO2 produced per hour of computer usage.
Temperatures generally rise as altitude increases in the?
Stratosphere. This is because the stratosphere is above the troposphere and contains the ozone layer, which absorbs UV radiation from the sun, causing temperatures to increase with altitude.
What are some solutions to global warming that this website can tell you about?
Some solutions to global warming that this website can provide information on include reducing greenhouse gas emissions through renewable energy sources, promoting energy efficiency, implementing sustainable land use practices, supporting carbon capture and storage technologies, and advocating for policies that address climate change.
What is the region of rising air around the equator called?
Intertropical Convergence Zone
----------------------------------------
In the seamen's speech the zone is referred as "The Doldrums" because of its erratic weather patterns with stagnant calms and violent thunderstorms.
What are predictions for climate change based on?
Predictions for climate change are based on scientific research and computer models that analyze historical data, current trends, and future projections of greenhouse gas emissions. These predictions consider factors such as temperature rise, sea level rise, extreme weather events, and impacts on ecosystems and human societies.
Do cactus produce carbon dioxide and take oxygen?
During the day, cacti take in carbon dioxide through their stomata for photosynthesis and release oxygen as a byproduct. At night, they continue to respire like other plants, taking in oxygen and releasing carbon dioxide.
How does marshlands get effected by climate change?
Depending upon the location, climate change is expected to have different relative outcomes. Although temperature increases are largely expected globally (which is going to increase evapotranspiration), changes to rainfall vary considerably between places. Many places are expected to receive less rainfall, which, with increased evapotranspiration, are going to increase the desiccation of marshlands.
What human activities can cause greenhouse gases and what greenhouse gases do they cause?
Burning fossil fuels like coal, oil and natural gas, and deforestation, are the human activities. The first releases carbon dioxide, and the second means the trees are no longer able to absorb the carbon dioxide from the atmosphere.
What gas in the atmosphere will bring about a warming of the lower atmosphere?
Carbon dioxide is the primary gas responsible for warming the lower atmosphere through the greenhouse effect, where it traps heat from the Earth's surface. Other greenhouse gases like methane, water vapor, and nitrous oxide also contribute to this warming effect.
Why is it dangerous to burn carbon-based fuel in a closed space?
Burning carbon-based fuel consumes oxygen and produces carbon monoxide, a toxic gas that can be lethal in high concentrations. In a closed space, the lack of ventilation can lead to a build-up of carbon monoxide, displacing oxygen and causing asphyxiation. It is important to ensure proper ventilation when using carbon-based fuels indoors to prevent this dangerous situation.
