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.

The greenhouse effect is the natural warming in earth's what?
The greenhouse effect is the natural process where certain gases in Earth's atmosphere trap heat from the sun, leading to warming of the planet. This helps regulate Earth's temperature and make it suitable for life.
How can human activity affect the amount of rain?
Human activities such as deforestation, urbanization, and industrialization can lead to changes in land cover and atmospheric composition, which can in turn affect the amount and distribution of rainfall. These activities can alter local climate patterns and disrupt natural water cycles, ultimately influencing the amount of rain that falls in a particular region.
What are four weathering agents on earth?
the main agents of physical weathering would be hail, snow, sleet, and rain (sometimes temp.)
Greenhouses themselves are not inherently dangerous, but certain factors like chemical treatments, poor ventilation, or improper handling of equipment can pose risks. It's important to follow safety guidelines when working in a greenhouse to prevent accidents or exposure to harmful substances.
As the temperature of a given volume of saturated air decreases what happpens tot he condensation?
As the temperature decreases, the ability of saturated air to hold moisture decreases. This can lead to condensation as the air cools below its dew point temperature, causing water vapor to turn into liquid water droplets.
Weathering refers to the group of destructive processes that change the physical and chemical character of rocks at the Earth's surface. It includes processes like mechanical weathering, chemical weathering, and biological weathering that break down rocks into smaller particles or alter their composition.
What relationship between insolation and terrestrial radiation causes temperature to rise?
Insolation (incoming solar radiation) heats the Earth's surface, causing it to warm up. The warm surface then emits terrestrial radiation (heat energy) back into the atmosphere. Greenhouse gases in the atmosphere trap some of this terrestrial radiation, leading to an increase in temperature, known as the greenhouse effect.
Why do you think Carbon dioxide levels have continued to rise during the past 45 years?
Humans continue to burn fossil fuels (coal, oil and natural gas) at a great rate in industry, travel and to generate electricity. This releases extra carbon from millions of years ago.
They also cut down forests all over the world that used to absorb carbon dioxide from the atmosphere.
What era was the ozone layer developed?
The ozone layer developed around 2.4 billion years ago during the Great Oxidation Event in the Earth's history. This event marked a significant increase in oxygen levels in the atmosphere, leading to the formation of the ozone layer.
How might the continued reduction of the polar ice cap influence transportation and shipping?
The continued reduction of the polar ice cap may lead to increased shipping activity through new shorter routes, such as the Northwest and Northeast Passages, potentially reducing transportation costs and voyage times. However, it also presents challenges due to the need for specialized ice-class vessels and concerns about environmental impacts from increased maritime traffic in the region.
Is the amount of air pollution increasing or decreasing?
The air pollution would be constantly increasing unless everyone stopped using any form of electrical appliance etc.
I would think that the increase is less than it was 50-10 years ago though.
Warm air can be described as density and or as humidity. Both which means the same can also make your hair frizzy. It means its not hot nor is it cold its like heat and cold combined. 50/50.
What best exemplifies global collaboration for a sustainable environment?
International agreements like the Paris Agreement, where countries come together to address climate change collectively, exemplify global collaboration for a sustainable environment. These agreements set targets for reducing greenhouse gas emissions and encouraging adoption of renewable energy sources on a global scale. Additionally, initiatives that promote knowledge-sharing, technology transfer, and capacity-building across borders contribute to sustainable environmental practices worldwide.
Advantage and disadvantage of climate change?
Well an advantage of climate change is that we have warmth but there are more disadvantages: Firstly Icebergs and glaciers melt so eskimo's and other land animals like polarbears won't have any land to live on. Climate change causes floods in Bangladesh.
How can you prevent the damage the greenhouse effect causes?
There is a natural greenhouse effect that keeps the planet warm. There is now an accelerated, or enhanced, greenhouse effect that is caused by the overwhelming amounts of extra gases man has released by burning fossil fuels.
- We have to convince our governments to take serious action to slow the amount of greenhouse gases going into the atmosphere.
- We have to cut down our own energy use, as the production of electricity, largely by burning fossil fuels, is responsible for the increasing amounts of greenhouse gases.
- We have to make green transport choices (walk, cycle, car-pool, bus, train, rather than private vehicle and plane).
- We have to replant the great forests of the world, which we destroyed. They can absorb carbon dioxide from the atmosphere, and store the carbon for hundreds of years.
Negative effect of globalization on education?
- increasing crimes
- loss of culture(dress,language,food)
- Corruption
- spreading of diseases
- environmental degradation(pollution,global warming)
- increase in child labor and slavery
- Gap between poor and rich
- Loss of economy(brain drain)
What is the percent of global warming caused by cars?
In 1999, in the US, more than 30 percent of fossil fuel related carbon dioxide emissions were a direct result of transportation. With about two-thirds of this being from petrol consumption by motor vehicles and the remainder coming from diesel and jet fuel use in lorries and aircraft, respectively. Worldwide, motor vehicles currently emit well over 900 million metric tons of CO2 each year. These emissions account for more than 15 percent of global fossil fuel CO2 releases.
The ozone layer is found within the stratosphere, a layer of Earth's atmosphere located approximately 10 to 50 kilometers above the surface. It helps protect living things from excessive ultraviolet radiation by absorbing and filtering out harmful UV rays from the sun.
The warm air will continue to cool and condense, leading to the formation of precipitation. This could result in rain, snow, or other forms of precipitation depending on the temperature and atmospheric conditions.
Why will hydrogen not contribute to global warming?
If we could find an easy and cheap way to obtain hydrogen from water (H2O), then hydrogen is a pure and green fuel with no emissions except water vapor. Water vapor would briefly remain in the atmosphere, but it soon builds into clouds and falls as rain, so it would not contribute to global warming the way carbon dioxide is. Cars and industry could run on hydrogen, as could electricity power stations. So hydrogen would not contribute to global warming.
How do you get the same amount of oxygen to dissolve in plasma as carbon dioxide you would have to?
To get the same amount of oxygen to dissolve in plasma as carbon dioxide, you would need to increase the partial pressure of oxygen in the gas phase. This increase in pressure would drive more oxygen molecules to dissolve into the plasma to reach equilibrium with the gas phase. The solubility of a gas in a liquid is determined by Henry's Law, which states that the amount of gas dissolved is directly proportional to its partial pressure in the gas phase.
What problems does global warming cause for animals and vegetation?
It may or may not because if the global warming is not so bad it will not effect plant and animal communities if global warming is bad it will effect plant and animal communities. If the plant life gets effected by global warming, some animals can be effected to because they eat the plants! Same thing for the plants that eat insects and stuff!
What was the famous earthquake in 1989 california?
That was the Loma Prieta Earthquake of October 17, which struck near Santa Cruz, south of San Francisco. It Killed dozens, injured thousands, caused several billion dollars worth of damage, and disrupted game 3 of the 1989 World Series.
What do scientists believe is the primary cause of earth's climate fluctuations?
If you mean the present climate change, then scientists agree that it is caused by man's deforestation and burning of fossil fuels.
If we are discussing actual major temperature changes though, like the warming trend of the past 11,000 years the answer is far different and the changes far ore profound.
What is known about our long term history of climate change comes primarily from a single source. The glacial samples from Lake Vostok in Antarctica. These samples tell us, with remarkable detail some interesting things:
1. we know the planet goes through cycles. These cycles are regular and the longest is just over 100K years long. We are in the warmest section of this long cycle currently.
This warming is believed to be caused by planetary alignments of the major planets in our solar system. Our orbit around the sun is far from a perfectly circular orbit and the distance our planet is from the sun varies greatly. When all of the larger planets are scattered throughout the solar system we have a far more elliptical orbit the when the larger planets are all on a single side of the sun. This event happens once every 100K years and corresponds to these warm periods. This current cycle has seen an overall warming of about 11 degrees C from this issue. Man's contribution is an unknown portion of a partial contribution of the 0.3 degrees of warming we have seen since 1939. Even if man is the sole contributor, it is nothing compared to this warming.
Other portions of our orbit that influence our climate are listed within the Milankovich effect link below.
2. Solar variation is agreed by climate experts to have assisted in temperature variations, including the current cycle of warming. The problem here is that, according to the IPCC, (the United Nations body that is considered the bible of climate change) that while we know it has caused some portion of the current climate change, what portion and how is still "very poorly" understood.
(see IPCC links)
While there are other issues that have caused the major climate changes of the past few thousand years, these two are in the primary category.
3. It is also likely that a wobble in the Earth's axis of rotation contributes to these ice age cycles we've seen wax and wane over the past 800,000 years (based on ice cores, so may not be globally representative in details, but it is in the big picture). The cycle has been quite regular the last 400,000 years, and seems to be getting more pronounced and longer with time. Five times in the last 400,000 years we've seen a very steep rise in temperatures to come out of an ice age, then the temperatures begin a much slower descent back into ice age conditions. The most recent cycle (before the sharp warming that started about 25,000 years ago) was most pronounced, with Earth's average temperature possibly fluctuating by as much as 15C from the peak ~125,000 years ago to the nadir ~30,000 years ago. Taking anthropomorphic global warming out of the equation, and looking purely at the ice age cycle, we appear to have reached the end of the cycle's sharp temperature increase several thousand years ago, and should be in the early stages of the gradual cool-down toward an ice age.
What process releases carbon into the atmosphere from fossil fuels?
Combustion. Fossil fuels contain carbon, hydrogen, Nitrogen, Oxygen and some other elements. But the largest is Carbon. So when such fuels burn they combine with the Oxygen and Nitrogen in air to form Carbon dioxide, Nitrogen oxides etc. Any form of carbon when burns produces carbon dioxide.
