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 does it mean by global characteristics?

Global characteristics refer to overarching qualities or traits that are common across a wider scope, such as a system, population, or region. These characteristics can include trends, patterns, or features that are pervasive and impactful on a larger scale. Understanding global characteristics can provide insights into broad phenomena or dynamics.

What would make the greenhouse effect stronger?

An increase in greenhouse gas emissions, such as carbon dioxide and methane, would make the greenhouse effect stronger. These gases trap heat in the Earth's atmosphere, leading to the warming of the planet. Deforestation, industrial activities, and burning of fossil fuels are some of the primary sources of these emissions.

What 's known about climate history over the last 10000 years?

The last 10,000 years of climate history are the years immediately following the Ice Age. Over these 10,000 years, the climate has invariably become warmer, as evidenced by the amounts of ice caps melting within the globe.

How has the carbon dioxide in Our Atmosphere changed since 1750?

Levels of carbon dioxide in 1750 were approximately 275 parts per million. Today (2011) concentrations are approximately 392 ppm, an increase of more than 40 percent.

What process adds carbon dioxide the atmosphere?

The burning of fossil fuels in activities such as transportation, electricity generation, and industry is a major process that adds carbon dioxide to the atmosphere. Deforestation also contributes to increased atmospheric carbon dioxide levels by reducing the number of trees that can absorb CO2 during photosynthesis.

What happens when too much heat is trapped into earth?

due to increase in earths temperature we may have global warming which leads to melting of arctic glaciers which may lead to to the flooding of the coastal areas and in short effecting the flora and fauna of the planet.

How do you reduce human impact on climate change?

We have to move to renewable energy for all our power.

The key problem we face is to keep reducing the consumption of non renewable resources as global population increases. Non renewable resources include fossil fuels and rare raw materials. While there are a wide range of technologies, ideas and processes that can address many of these problems the biggest issue we face is resistance to change.

While governments are controlled and influenced by major organisations we cannot positively impact the human race's impact on our planet. Developed economies rely on increasing consumption of resources, both renewable and non renewable.

So we need to influence our governments and organisations.

What is an example of a human activity that contributes to greenhouse gases?

Two things that humans do that contribute to greenhouse gases is

  1. burn fossil fuels (coal, oil and natural gas) in transport and electricity production.
  2. Cut down forests all over the world that used to remove carbon dioxide from the air.

When you burn vegetation how does it affect carbon dioxide levels in the atmosphere?

Burning vegetation adds to the carbon dioxide levels in the atmosphere. However, that carbon dioxide was recently removed from the air when the plants were growing, so burning vegetation is carbon neutral.

Burning fossil fuels (coal, oil and natural gas), of course, releases extra carbon dioxide that has been hidden away for 300 million years.

Who is the British Climate Change Minister?

The current British Secretary of State for Energy and Climate Change is Edward Davey.

Which activity produces the smallest amount of greenhouse gases?

Humans produce greenhouse gases in many ways. Operating a generator or cooking with gas both will produce greenhouses gases. However, riding a bicycle will not.

Why could the melting of permafrost cause a runaway greenhouse?

It is thought that a vast amount of carbon dioxide is held imprisoned within the permafrost. If the permafrost was to melt, the carbon dioxide released would add considerably to the greenhouse affect.

What of these is the most likely result of the polar ice caps melting?

The most likely result of the polar ice caps melting is a rise in sea levels, leading to coastal flooding and the displacement of communities living in low-lying areas. This can also disrupt global weather patterns and accelerate climate change by releasing stored greenhouse gases.

What is global culture?

A dominant global culture is a nation or way of life that tends to cause changes in most cultures. Today, the United States is a good example of a dominant global culture.

If the rate at which we produce CO2 were to stop rising the levels of CO2 in the atmosphere would?

There is no exact answer yet to this question. If we stopped producing carbon dioxide (CO2) now, the extra CO2 we have added to the atmosphere would probably stay there for many many years.

The InterGovernmental Panel on Climate Change (IPCC) in its 2007 report, talking about the increased levels of carbon dioxide, says, "About 50% of a CO2 increase will be removed from the atmosphere within 30 years, and a further 30% will be removed within a few centuries. The remaining 20% may stay in the atmosphere for many thousands of years."

Why does sea level rise and fall during interglacial and glacial periods?

During glacial periods, sea levels drop because water is stored in continental ice sheets. During interglacial periods, ice melts and sea levels rise as water is released back into the oceans. These fluctuations in sea level are part of the Earth's natural climate cycles.

How does solar power contribute to global warming?

The use of solar power (photovoltaic panels [PV], solar hot water, Concentrated Solar Power [CSP]) does not contribute to global warming.

The original heat from the sun, of course, is the source of global warming, because we are trapping more and more of its heat.

It is the heat from the sun (solar power) that warms the earth. The earth then radiates heat back up into the atmosphere which warms the greenhouse gases. Because humans have put extra greenhouse gas up there (mostly carbon dioxide, but also some methane), this also warms up. This makes the planet warmer than it would normally be. This is global warming.

What is the global world and what are the issues in the international community that are most concerning and why?

well people don't really know about this alot but today i will teach

well the issues are that when the sun rises it contains alot of heat out so it really

hit other planets so that why we have cold and heat

Is climate change irreversible?

If humans continue to burn fossil fuels and all other natural resources, continue emitting harmful gases, etc, it will be irreversible. If humans change their ways, yes, Climate Change is fully irreversible. By turning to other methods of obtaining energy, becoming aware of current problems, and acting upon it, yes, Climate Change and Global Warming can be reversed.

Can you reverse the melting of ice?

No, once ice has melted, it cannot be reversed back into its solid state without the application of freezing temperatures or other methods of solidification.

Is rushing water a nuclear source of energy?

No, rushing water is not a nuclear source of energy. It is a renewable energy source known as hydropower, which is generated by harnessing the energy of flowing water to produce electricity through the use of turbines. Nuclear energy, on the other hand, is generated by splitting atoms in a process called nuclear fission.

What causes more carbon dioxide in the atmosphere?

Human activities such as burning fossil fuels (coal, oil, gas), deforestation, and industrial processes are the main sources of increased carbon dioxide in the atmosphere. These activities release carbon that has been stored for millions of years, leading to an imbalance in the carbon cycle and contributing to global warming.

How do you increase amount of carbon dioxide in greenhouse?

Simplest would be to remove any plants from the greenhouse, then spend some time in there yourself. Plants remove CO2 from the air, while your breathing would introduce CO2 into the air.

If you are dead set on keeping your plants in the greenhouse (weird, I know), then most things that burn or decompose will add some form of CO2 to the air.

Out of curiousity; why would you want higher levels of CO2?
