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.

Is bio energy an example of non renewable resource?
No, bio energy is considered a renewable resource because it is derived from organic materials like plants and waste that can be replenished or grown again. It is a sustainable source of energy that can be continually produced without the risk of depletion.
What do you know about greenhouse gases?
Emissions means "what comes out", or "what is released".
When we talk about greenhouse gas emissions we are usually referring to carbon dioxide, which is emitted when we burn fossil fuels. It can also refer to methane, another greenhouse gas, which is emitted from cattle and from melting tundra.
its is emissions from cars , fridges, factory's it goes into the atmosphere and coats things such as tree's and they cut the trees down and then it is less oxygen
What has happened to average global temperatures during the 20th century?
When we started this century, the world was in a period climatologists refer to as the mini ice age. Temperatures were already 0.1 degrees below normal as we enetered the period and dropped to almosy 0.5 degrees cooler then normal. After 1913, temperatures gradually rose until 1944. From 1944 until the late 70's we saw a decline in temperatures globally (on average). After 1979 we saw an increase in temperature once again. Temps finally reached the 1944 high points again in 1998 (and surpassed that temp by 0.1 degrees.) Since this time we have seen temps stay at this higher temp and vary slightly (as of late slight declines). 2010 tied, or possibly exceed 1998 by 0.01 of a degree (accuracy 0.16). This makes the past decade the warmest decade on record despite the lack of additional long term warming this decade. We should never view single years when referring to climate. Five or ten year averages make far more sense. The longer periods show that the planet has, on average warmed an additional 0.25 since the temps of 1944. The current trend is downward, although we are still near peak temps for the past hundred years.
If we view the 1901 temps and compare to 2001 (the twentieth century), we see about 0.414 degrees of total warming from the global average for the century. This compares with the past ten thousand years of warming (11 degrees total or 0.11 degrees per century average).
It is important to remember though that accurate temperatures on a global scale were impossible until 1979. The error factor gets much larger as we go back in time and before 1979 temperatures carry higher inaccuracies. The averages also ignore periods of warmer and cooler climate then present, such as the medieval warm period. Another significant factor is that we had a mini ice age period in the late 1800's. This caused our 1900 temp to be lower then the averages of the historical past. There is attached a great NOAA link showing temperatures from 1880 until present which graphically shows the temps. Notice how they show a very regular sine wave pattern and direction of current trends. (see attached)
Another answer:
The best way to view climate detail is not day to day but more of a five year running average. With this view, global temperatures declined 0.2°C from 1900 to 1910, then climbed 0.4°C until 1940. From 1940 to 1980 they staggered a tenth of a degree, but have risen another 0.4°C since. All indications are the temperature should continue rising at least as dramatically through the 21st century.
How are humans impacting on red wolfs?
When Europeans first settled in the Americas, many large predatory animals were considered a threat, and became targets for elimination. Among these was the red wolf, Canis Rufus, which roamed from Pennyslvania to Texas. The settlers did their job well, and the last 14 purebred red wolves were captured in the 1970's and placed into a captive breeding program.
Various areas were picked for re-introduction, and red wolves were placed on mainly island habitats for re-wilding, to teach them how to survive on their own.
Most of these failed, but one site, North Carolina's Alligator River Refuge, proved to be a major success. Eight wolves were released there in the 1980's, and after several setbacks (including some hybridization with coyotes), the red wolf population in the eastern NC reserve now numbers over 110 animals, the last of their kind in the wild today, although plans are to release others in their former range in suitable locations.
How can you use renewable energy resources without affecting neighbors?
To use renewable energy resources without affecting neighbors, consider installing solar panels on your own property to generate electricity without producing noise or emissions. You can also use geothermal energy by installing a heat pump system, which is quiet and underground. Additionally, wind turbines can be placed strategically to minimize noise and visual impact on neighboring properties.
What causes the most damage of the ozone layer?
Chlorofluorocarbons (CFCs) and other ozone-depleting chemicals released into the atmosphere are the main cause of damage to the ozone layer. These chemicals break down ozone molecules in the stratosphere, leading to ozone depletion and thinning of the ozone layer. UV radiation from the sun can then reach the Earth's surface, posing risks to human health and the environment.
Why does the earth have ice caps?
In the latest ice age almost the whole world was covered with ice (almost as far as the equator), most of that ice has now retreated as the earth's temperature increased but what is left is still at the coldest parts of the world i.e. the poles. The ice was created from water freezing at the low temperatures and then covered with snow.
The major climate change that is believed to have affected the distribution of living things on Earth the most is the last ice age, known as the Pleistocene epoch. During this time, large continental ice sheets covered much of North America, Europe, and Asia, leading to dramatic shifts in habitat and causing species to migrate and adapt to new environments.
What do greenhouse gases in earth's atmosphere do?
Greenhouse gases trap heat in Earth's atmosphere, acting like a blanket to keep the planet warm. This process is known as the greenhouse effect. However, an increase in greenhouse gases, such as carbon dioxide and methane, is contributing to global warming and climate change.
When farming practices such as overgrazing, climate change, and seasonal drought lead to degradation of land to the point where it cannot support plant life, it is called desertification. This process results in the transformation of productive land into desert-like conditions, leading to a loss of biodiversity and ecosystem services.
What are 6 possible effects of global climate change?
the six possible effects are
1)glaciers cease to exist
2)mountain peaks will no more be covered with snow
3) the temperature changes drastically in higher regions
4)due to such drastic climatic change mass extinction might occur
5)rivers start flooding hence the sea level rises,as the sea level rises it starts to engulf land
6 all creatures including us would be forced to evolve to the ever changing climate
What would happen to the land buried under the ice sheet if the ice melted?
If the ice sheet melted, the land underneath would be exposed. This could lead to the release of stored carbon and nutrients, affecting ecosystems and potentially contributing to climate change. It may also unveil geological features that have been hidden for thousands of years.
How can improved agriculture and forestry help reduce greenhouse gas emissions?
Cattle belch out a lot of methane (CH4), which is also emitted from rice paddy fields. Scientists are working to improve both these practices with the aim of reducing the amount of methane emitted. Reforestation and afforestation will also remove more carbon dioxide (CO2) from the atmosphere.
How have different conditions on earth contributed to global climate change?
Various conditions on Earth, including the burning of fossil fuels, deforestation, industrial activities, and agriculture practices, have increased greenhouse gas emissions, leading to global climate change. These activities trap heat in the Earth's atmosphere, causing temperatures to rise and disrupting weather patterns worldwide. Additionally, human activities have altered natural ecosystems, leading to further impacts on climate systems.
How do wind farms not contribute to global warming?
Wind farms do not contribute to global warming because they generate electricity by harnessing the kinetic energy of the wind, which is a renewable energy source that does not produce greenhouse gas emissions. This contrasts with fossil fuel power plants, which release large amounts of carbon dioxide and other greenhouse gases when burned to produce electricity.
What company is the largest contributor of greenhouse gases into the atmosphere?
The largest contributor of greenhouse gases into the atmosphere is the oil and gas company Saudi Aramco. They have consistently been identified as one of the biggest emitters of carbon dioxide globally.
Why is Co2 is a greenhouse gas?
CO2 is a greenhouse gas because it absorbs and traps heat in the Earth's atmosphere. When sunlight hits the Earth's surface, some of the heat is reflected back into space as infrared radiation. CO2 molecules in the atmosphere absorb this infrared radiation, preventing it from escaping into space and thus leading to a warming effect.
How does green house rise the sea levels?
Greenhouse gases trap heat in the Earth's atmosphere, causing global temperatures to rise. As a result, ice caps and glaciers melt, contributing to the overall rise in sea levels. This is because the melted ice adds more water to the oceans, leading to an increase in sea level.
What is global warming and why does it matter to the US?
Global warming is the warming of the earth since humans discovered fossil fuels (coal, oil and natural gas), and especially the rapid warming since 1980.
It matters to the US (and to the world) because if the earth continues to warm
- People will die from famines, flooding and heat waves.
- Countries (Pacific Islands) will disappear or have their coastal plains submerged by rising sea levels.
- Millions of people will have to move, and most of these will be extremely poor, with no support from their economically troubled governments.
- Animal, birds and fish species will disappear as their habitats go.
What are 4 ways the atmosphere effects life on Earth?
The atmosphere of planet Earth is a key factor behind the existence of life, and human survival. Layers such as ozone helps shield against ultraviolet (UV) radiation. The percent composition of oxygen also serves as critical to breathing. Lastly the natural greenhouse effect caused by the atmosphere has helped keep temperatures habitable.
A tungsten-halogen light bulb is most likely to cause a plant to wilt because it generates heat that can damage the plant cells and dry out the soil. Fluorescent light bulbs, whether red or blue, are generally better options for plant growth as they produce less heat and provide a spectrum of light that is beneficial for photosynthesis.
When a warm air mass and a cold air mass meet and neither can move the other the result is?
When a warm air mass and a cold air mass meet and neither can move the other, it results in a stationary front. This can lead to prolonged periods of clouds and precipitation as the contrasting air masses interact along the boundary.
How can local councils help to reduce carbon emissions?
Local councils can reduce carbon emissions by implementing policies that promote sustainable transportation options like biking and public transit, investing in renewable energy sources for local government operations, and launching awareness campaigns to educate residents on energy-saving practices. Additionally, councils can support initiatives to increase green spaces and promote energy-efficient building practices within the community.
What do people think global warming is?
Global warming is the wake up call for people to become more concerned about the environment and it has resulted to the modifications on the way people usually live their lives. People are more conscious when it comes to the usual choices in life like choosing energy saving appliances or using refurnished toner and inkjet cartridges.
What are global issues for uranium?
Uranium must be used as nuclear fuel for nuclear reactors, to produce electricity and heat. Nuclear energy is the most serious alternative to fossil fuels. But, attention: also uranium is a not a renewable resource ! Problems with nuclear energy are possible pollution and disposal of radioactive wastes; but these questions are now to the greatest extent solved.
