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.

What are some human activities that contribute to the worsening effect of global warming?
In our daily activities, whenever we contribute carbon dioxide or methane to the atmosphere we are adding to the greenhouse gas layer and making the world warmer. Carbon dioxide is put into the atmosphere during the production and burning of coal, oil and natural gas (to produce electricity). So in every day we contribute to global warming by: * using electricity in any form (TV, computer, heating and cooling, lights)
* traveling, using vehicles * eating food (it had to be grown, harvested and transported to you, then cooked) * wearing clothes (the material had to be grown, etc... same as food) * washing and drying clothes (all that water and electricity)
* buying a new computer (all the material and the production and transport used energy) * throwing something away into garbage, then into landfill, and buying a new one.
As you can see, just about everything we do contributes to global warming. We can't cut out everything. But we certainly can cut down on a lot of things. Compare your lifestyle with a simple farmer living in a poor country and think how big your global footprint (the amount of energy you use) is compared with his.
If we all did a little more of some of these it would help slow global warming:
* Turn off the lights when you leave a room. * Turn off TVs etc at the wall instead of with the remote. * Hang your clothes out to dry. * Use public transport or bicycle. * Recycle all those cans and plastic bottles. * Buy local food and eat it all. * Wear warmer clothes instead of turning up the heating. * and many more...
Methane is produced when organic matter decomposes anaerobically (without air). This happens in the intestines of some animals, and in landfill (garbage dumps). There are millions of cattle, pigs and sheep all over the world being raised for us to eat. So every time we eat meat some farmer has to buy an extra animal just to make up for it. So, to cut down on the amount of methane being added to the atmosphere we should:
* Eat vegetarian meals more often * Eat white meat (chicken) instead of red (beef, pig, sheep)
* Put food scraps into a worm farm or a compost bin Two products of respiration -- carbon dioxide and water vapor -- are greenhouse gases, so breathing contributes to global warming. Also, methane is a more powerful greenhouse gas than even carbon dioxide, so flatus, gas expelled from the digestive tract, known in the vernacular as farts, also contributes to global warming.
Is global warming more dangerous than resource depletion?
Both global warming and resource depletion pose significant risks to the environment and human civilization. Global warming can lead to more frequent and severe natural disasters, sea level rise, and disruption of ecosystems. Resource depletion, such as dwindling supplies of fresh water and minerals, can lead to resource conflicts and economic instability. Both issues require urgent attention and action to mitigate their impacts.
How is a gardeners greenhouse a miniature version of the greenhouse effect?
The greenhouse effect is called that becouse the earth naturally acts like a greenhouse but with the gases (like CO2) going up into the air, the barrier around the earth that acts like a greenhouse, makes the barrier stronger and that makes the earth get more warmer.
So...The more greenhouse gases we produce the warmer the earths temperture would be
What the 3 renuable energy resources?
Three examples of renewable energy are:
- solar,
- wind,
- hydro (dams, tidal and wave).
Three examples of non-renewable energy are:
- Coal,
- oil and
- natural gas.
What is the climate change in human activity?
Climate change is primarily caused by human activities, such as burning fossil fuels, deforestation, and industrial processes, which release greenhouse gases like carbon dioxide into the atmosphere. These gases trap heat, leading to a rise in global temperatures and disrupting Earth's climate system. The resulting changes include more frequent and severe weather events, rising sea levels, and shifts in ecosystems.
Which nwhat is not a physical injury you can prevent by warming up and cooling down properly?
One example of a non-physical injury that can be prevented by warming up and cooling down properly is muscle fatigue or soreness. A thorough warm-up can help prepare the muscles for exercise and reduce the likelihood of excessive fatigue or soreness post-workout. Cooling down allows for a gradual transition from high-intensity activity to rest, which can facilitate recovery and reduce muscle soreness.
How does aerosol have an effect on global warming?
Many hairsprays contain CFCs witch stands for chrolo flora carbonates. When the spray is sprayed the CFCs escape from the can and in the atmosphere in 20 years. It dissolves the cover of the ozone that the earth has witch stops blocking the sun and creates holes in the ozone layer.
The North Pole and the South Pole are just places. They have a lot of ice, and the ice is melting, faster in some places than in others. So the Polar Regions do melt, but they haven't completely melted yet.
What is energy created when the earth is heated?
The energy created when the Earth is heated comes from within the Earth's core, where heat is generated through the decay of radioactive elements and residual heat from the planet's formation. This heat energy drives processes like tectonic plate movement, volcanic activity, and the circulation of the Earth's molten iron core.
What is the single most important problem that should be addressed in global revision?
Climate change is the single most important problem that needs to be addressed on a global scale. Its impact is far-reaching, affecting ecosystems, economies, and societies worldwide. Addressing climate change requires collective action and cooperation among nations to reduce greenhouse gas emissions and mitigate its effects.
What gases are present in the environment?
The most abundant gases in the Earth's atmosphere are nitrogen (approximately 78%) and oxygen (around 21%). Other important gases include argon, carbon dioxide, and trace gases like methane and ozone. Additionally, water vapor is also an important component of the atmosphere.
How do carbon particles get into the atmosphere?
Carbon particles can enter the atmosphere through natural processes like volcanic eruptions and wildfires. Human activities such as burning fossil fuels, industrial processes, and deforestation also release carbon particles into the air. Once in the atmosphere, these particles can contribute to air pollution and climate change.
What issue is affecting the earth?
Climate change is a major issue affecting the Earth. Human activities such as burning fossil fuels and deforestation are increasing greenhouse gas emissions, leading to global warming, extreme weather events, rising sea levels, and loss of biodiversity. Addressing climate change requires global cooperation and immediate actions to reduce emissions and transition to sustainable practices.
How is global warming affecting the arctic wildlife?
Global warming is melting a lot of ice in the arctic regions and the wild life is getting less and less areas to live, breed, feed themselves and babies
A:The Arctic has warm seasons and cold seasons.During the warm season, snow melts, and grass and plants grow in the arctic tundra.
Ice melts, and areas of the Arctic Ocean opens up.
Many species thrive in the warmer summer months, and have lean times during the winter. Many migratory aquatic species such as narwhals depend on the annual summer ice melt to open patches in the ice.
Arctic foxes even have white coats in the winter, and grey coats in the summer.
Polar Bears, however, are one species that are more effective winter hunters than summer hunters, so the warming weather may be hard on them.
If significant areas of permafrost is lost, then there may be some habitat decrease as plants and animal ranges may shift, but many species will thrive with somewhat warmer temperatures.
Where could you store nuclear waste from power stations?
At present, and in fact since commercial power started, in the US the spent fuel has been stored on the power station sites, in water filled storage ponds. In recent years these have had to be supplemented in some locations with dry cask storage. Since the waste has to be stored for centuries to come this cannot be seen as satisfactory, and some permanent repository will have to be provid ed.This would have to be underground in a very stable geologic area with no risk of flooding. However no federal government has been willing so far to force this issue through against local opinions.
Where does the greenhouse effect occur?
The greenhouse effect occurs in the Earth's atmosphere. Greenhouse gases such as carbon dioxide and methane trap heat from the sun, leading to warming of the Earth's surface. This process is essential for maintaining the planet's temperature suitable for life.
Why should you concerned of rising sea levels?
Rising sea levels can lead to coastal flooding, displacement of communities, loss of habitat, and increased storm surge damage. This can impact infrastructure, agriculture, and economies, making it a serious threat to human life and livelihoods. Understanding and addressing the causes of rising sea levels is crucial for mitigating these risks.
Why global warming is considered as the social problem?
Global warming is a social problem because of many factors. Factors like emissions for example, emissions tests are only in a few states. With more emissions tests on vehicles, this would lessen the global warming, not by leaps and bounds but it would help. If more people recycled, and cleaned up waters this could help.
Does biomass emit greenhouse gases?
Yes, burning plants produce carbon dioxide, after all oxygen is flameable.
>Burning of any hydrocarbon generates carbon dioxide as a by-product. Plants are mainly composed of various glucose and cellulose polymers, which essentially are hydrocarbons, which when burned, release CO2 and leave an ash residue.
A rough example to consider the burning of hay. The black smoke released as a by-product of its incineration, is CO2 (along with other gases).
What happens when there is a lot of carbon dioxide in the Atmosphere?
The Earth would be unable to radiate energy away from itself at a rate, sufficient to maintain an energy balance. Earth would become warmer and warmer until something happened to bring the energy cycle back into balance, like another year without summer or an increase in Earth's CO2 sequester rate.
Increased levels of atmospheric CO2 are already a reality, but the net effect this has on warming is very difficult to quantify. Scientific inquiries, concerning this and other warming issues, are ongoing.
Carbon dioxide absorbs, and releases heat. To over simplify: The CO2 in the air allows heat to radiate from the sun to the earth. However, CO2 interferes with the heat that is radiated by the earth into space. It absorbs this radiation and releases some of it back to the earth.
Over time, if this condition is allowed to continue and to evolve, it results in a warming shift in Earth's energy balance, a net gain in energy (heat) for earth and its atmosphere.
How can individuals slow down climate change?
- Educate your friends about it.
- Ask questions of politicians and big companies about what they are doing to slow climate change.
- Buy green energy for your home.
- Reduce any use of fossil fuels (coal, oil and natural gas).
- This means reduce unnecessary electricity use. Turn off all those lights. Turn your machinery and equipment off at the wall. Machines on stand-by add 10% to your utility bills.
- Plant trees and get others and local councils to do the same.
- Support political parties that have plans to reduce greenhouse gas emissions and carbon dioxide.
- Join or form an environmental organization.
What evidence is there that icebergs are actually melting?
Evidence that icebergs are melting includes measurements showing a decrease in iceberg size over time, satellite images showing changes in the extent and thickness of icebergs, and scientific studies documenting rising sea levels due to the melting of icebergs and glaciers. Additionally, increased water temperatures in polar regions and shifting ecological patterns further support the observation of iceberg melting.
Why is it important to address Our over use of electricity?
Even British Columbia, with all of our extensive existing - [we all need to address micro-Hydro] - Hydro-electric resources, is a Net Importer of Coal Fired Oregon power.
Shanghai City needs seventeen dirty-coal fired Power Plants 24 hours.
Global warming is causing the Earth's average temperature to rise due to an increase in greenhouse gases trapping heat in the atmosphere. While there are natural cycles of cooling and warming over millions of years, the current rate of global warming is much faster due to human activity. The melting of ice caps is a direct consequence of this rapid warming, not a reflection of a long-term cooling trend.
Why is the sun's radiation reflected back into space?
The sun's radiation is reflected back into space by the Earth's atmosphere, clouds, snow, ice, and other reflective surfaces. This reflection helps regulate the Earth's temperature by preventing excessive heating.
