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.

Do humans absorb gases?

Yes, humans can absorb gases through the respiratory system when they breathe in gases present in the air. The gases pass through the lungs and are diffused into the bloodstream where they can be transported to different parts of the body.

How does carbon dioxide leave the atmosphere and end up in living things?

One big way it leaves the atmosphere is by being consumed by living plants in the process of photosynthesis that results in sugars and other carbon-containing compounds like cellulose. Herbivores (plant-eaters) then consume these and integrate the carbon matter, so to speak, into their own systems.

What are the artificial sources of carbon dioxide in nature?

Artificial sources of carbon dioxide in nature come from human activities, such as burning fossil fuels like coal, oil, and gas for energy, industrial processes, deforestation, and land-use changes. These activities release excess carbon dioxide into the atmosphere, contributing to the greenhouse effect and global warming.

How much CO2 is put in the atmosphere each year?

Approximately 40 billion tons of CO2 are emitted into the atmosphere each year from human activities, such as burning fossil fuels, deforestation, and industrial processes. This has led to an increase in the concentration of CO2 in the atmosphere, contributing to global warming and climate change.

How much carbon in metric tons is stored in the atmosphere?

Most of carbon in the atmosphere is in the form of CO2. At nearly 400 ppm, that pencils out to 3 trillion tonnes (metric tons).

To single out how much of that is carbon we need to multiply by 12 (molecular weight of carbon) and divide by 32 (molecular weight of O2). That works out to 1.1 trillion tonnes.

There is additional carbon in the atmosphere in the form of methane (CH4), carbon monoxide (CO), chlorofluorocarbons (CFC), and a few other carbon compounds. If you count pollen, wind born leaves, birds, and other things occasionally swept aloft, the atmosphere temporarily suspends much more carbon yet.

What are the word equations for processes that release or store carbon doixide?

Some of the process that fix carbon dioxide are limewater + carbon dioxide equals calcium carbonate + water. Another is calcium carbonate + water + carbon dioxide = aqueous calcium bicarbonate. These equations work in reverse to release carbon dioxide.

When is world global warming day is celebrated?

World Global Warming Day is not an officially recognized global event, but Earth Day on April 22 is often used as an opportunity to raise awareness about climate change and global warming.

Carbon dioxide is heavier then air how can it be a greenhouse gas?

Carbon Dioxide (CO2) does not form a lower layer because it mixes easily with the other gases in the atmosphere, even though it is heavier than air.

You may be getting the gases confused though. All carbon dioxide, except aircraft exhaust and bird expiration is formed in the lower atmosphere. Carbon dioxide normally stays in the lower atmosphere also. If not, the gas would build up fairly quickly. Billions of tons of carbon dioxide are removed very year by the oceans and our planet life when it comes in contact with them. If we did not have this contact, they would be unable to remove the carbon dioxide from the air. Ozone on the other hand is formed high in the atmosphere when sunlight hits oxygen. This gas is found mainly at higher altitudes.

Does physical weathering inhibit chemical weathering?

Physical weathering can enhance chemical weathering by increasing the surface area available for chemical reactions to occur. This is because physical weathering breaks down rocks into smaller pieces, exposing more surface area to chemical processes like oxidation and hydrolysis. So, physical weathering does not inhibit chemical weathering; instead, it can actually facilitate it.

What heat is caused by the greenhouse effect?

Global warming in the atmosphere is the heat caused by the greenhouse effect.

Carbon dioxide, methane and other greenhouse gases produced by industrial factories are the main causes of greenhouse effects.

What form of heat transfer is caused by the greenhouse effect?

There are three types of heat transfers: conduction, convection and radiation. The heat transfer caused by the greenhouse effect is radiation.

Is the air cleaner today or was it 20 years ago?

In the USA, the air is much cleaner now - as anyone who was alive 40-50 years ago will tell you, especially around some of the bigger cities. This is due to several major environmental laws passed in the 1970's.

Elsewhere in the world, particularly in the developing world and especially China and India, the air is much dirtier than it was 20 and 30 years ago. Some of the cheapest energy and manufacturing techniques are also the dirtiest. These countries are just now beginning to deal with their air pollution simply out of necessity. Poor air quality takes a tremendous toll on human health when it is so severe, and you can attach a monetary value to these damages.

What is A biological community's productivity measured of?

A biological community's productivity is measured by the amount of energy captured through photosynthesis by primary producers, such as plants, and transferred to higher trophic levels. This can be quantified by measuring the rate of biomass production or carbon fixation within the community. The productivity reflects the overall efficiency and health of the ecosystem.

Can gases in the atmosphere gain energy from the land and water?

Yes, gases in the atmosphere can gain energy from the land and water through processes like conduction, convection, and radiation. Heat from the Earth's surface is transferred to the air by these mechanisms, which leads to the warming of the atmosphere.

Do global companies do more harm than good?

Global companies can have both positive and negative impacts. While they can bring economic growth, job opportunities, and technological advancements, they can also exploit resources, contribute to environmental degradation, and perpetuate social inequality. It is important to balance the benefits with the potential harm and hold companies accountable for their actions.

What is an example of a physical weathering and what is weathered?

An example of physical weathering is freeze-thaw weathering, where water seeps into cracks in rocks, freezes, expands, and causes the rock to break apart. The rock is weathered in this process, as the repeated freezing and thawing weakens and eventually breaks it apart.

What does a scientist do with the data collected?

What a Scientist Does

"Scientist" is a very broad term. There are many different jobs and fields of expertise here. The following page has some good information on the subject.

Science and technology have continually modified human existence. As a profession, the scientist of today is widely recognized. Scientists include theoreticians who mainly develop new models to explain existing data and predict new results, and experimentalists who mainly test models by making measurements - though in practice the division between these activities is not clear-cut, and many scientists perform both tasks

Sample of informative speech about global warming?

A reaction paper about global warming should include scientific data, as well as personal reaction and opinions. Additionally, it should include paragraphs supporting the overall personal reaction.

Why is the earth neither warming up nor cooling down?

The Earth's temperature is influenced by many factors, including greenhouse gas emissions, solar radiation, and natural climate cycles. Currently, the increase in greenhouse gases from human activities is causing the Earth to warm at an accelerated rate, offsetting potential cooling influences. However, natural variations can still cause short-term fluctuations in temperature.

What is the source of warming the upper stratosphere?

The source of warming in the upper stratosphere is primarily the absorption of high-energy solar radiation by ozone molecules. This absorption leads to an increase in temperature as the ozone molecules absorb the energy and heat up the surrounding stratospheric air.

What are the advantages and disadvantages of doing something now to slow global warming?

The evidence for global warming is now considered "exceptionally strong and beyond doubt" and actions this decade will determine the impact of climate change for the rest of the century .

Greenhouse gas emissions must peak and then begin to fall rapidly within the next few years if the world is to avoid dangerous warming of up to 7 degrees and beyond in his century. "If you leave the peaking year until 2020 you are going to have to reduce emissions at 9 per cent a year after that," Professor Will Steffen said. "I think this is almost impossible to do unless you put the economy on a war footing." This provides us with a clear incentive and advantage in doing something now to slow global warming while it is still possible without social and economic upheaval.

The only real disadvantage in doing something now to slow global warming is political. Politicians hate taking action that may have a short-term cost to anyone, but for which the greatest benefits will accrue after they have retired from political office.

Why did the amount of carbon dioxide in the atmosphere stay constant for thousands of years?

The levels of carbon dioxide in the atmosphere stayed constant for thousands of years because of the carbon cycle, which moves carbon throughout the air, oceans and land. There was also no burning of fossil fuels (coal, oil and natural gas), and nobody had cut down the great forests of the world.

What are earths main climate zone and how does latitude effect the climate zones?

There are three major climate zones on earth. These are the polar zone, temperate zone, and tropical zone. Latitude plays a huge role because the polar zones are higher latitudes while those zones extremely close to the middle of the earth is tropical.

What are the features of Global Warming?

Global warming refers to the long-term increase in Earth's average surface temperature due to human activities like burning fossil fuels and deforestation. Its main features include rising temperatures, melting ice caps, sea-level rise, extreme weather events, and biodiversity loss. These changes have significant impacts on ecosystems, weather patterns, and human societies worldwide.
