Global Warming

In the exosphere, temperature increases with altitude. This is because the particles in the exosphere are far apart, so there is no transfer of heat through conduction or convection. Instead, the few particles present gain energy from solar radiation, causing an increase in temperature as altitude increases.

A careful examination of the data clearly indicates that yes, human activity has indeed contributed significantly to global warming and hence climate change over the past century.

Normal background variations in atmospheric CO2 ranged from 250 to 280 ppm for the past 800,000 years. But beginning with the industrial revolution around 1700, CO2 shot up rapidly from 280 to 290 ppm in just 200 years, about ten times faster than the historical rate of change.

From 1900 to 1950 CO2 rose another 10 ppm, an increase in half a century of the same magnitude in times past took 20 centuries. That is a 40 fold increase over the natural background rate of change.

Within the next two years CO2 will pass 400 ppm, and it will reach 500 ppm before 2050. Earth's temperature is expected to climb 2° to 4° degrees C (4° to 8° Fahrenheit) by 2100.

No. Enhanced global warming is the current slang for this situation.

Man induced global warming is another term used.

We'll find out.

Earth is fairly large, its diameter is about 8000 miles. Such a big world requires time to adjust to certain changes we have introduced. One of those changes is the substantial increase in atmospheric carbon dioxide levels over the past two hundred years.

Climate scientists anticipate the earth will continue adjusting to current increased levels for centuries to come. Increasing the level will simply make these anticipated changes occur faster. Glacial melt water will increase ocean levels. We expect an increase in the strength of storms, though not necessarily an increase in storm frequency. May low lying coastal areas are expected to flood. Many areas will suffer greater, more prolonged periods of drought. A few will see increased rainfall over historic norms.

Climate is always changing a little bit from one place to another over time. The big question is whether human activity has accelerated the rate of change. Most scientists are confident the data indicates that we have.

Breathing in too much polluted air can lead to various health issues, such as respiratory infections, asthma exacerbation, chronic obstructive pulmonary disease (COPD), and heart problems. Prolonged exposure to polluted air is associated with an increased risk of lung cancer and other serious health conditions.

Yes. They can and they do. Any increase in the level of carbon dioxide or methane in the atmosphere will result in an increase in average global temperatures. This typically results in evaporation of additional water vapour, creating a slight amplifier effect, to further increase surface temperatures.

Not necessarily. While areas at high altitudes generally experience cooler temperatures than low-lying areas, latitude still plays a significant role in determining the overall climate. For example, a high-altitude area near the equator will be warmer than a high-altitude area near the poles.

A warming room in a home is a space typically close to a kitchen where food can be kept warm before serving. It often features built-in cabinets or drawers with heating elements to maintain food temperature. Warming rooms were more common in older homes and mansions, but are less commonly found in modern homes.

No. The global warming affect only involves the atmosphere. Earth's mantle generates it's own heart via the slow decay of radioisotopes, and is well insulated from the cooler atmosphere by earth's oceans and crustal rock. In general, heat dissipates, so the mantle would not gain heat from the much cooler atmosphere.

Zebras are dependent on the grasslands of Africa for their habitat. If the climate changes, as scientists are predicting, then the already warm African countries will be most at risk. If the grasslands dry up then there will be no food for the zebras and they will likely die out.

Energy is renewable if it comes from a renewable source. Wave power, capturing the movement of the tides and ocean waves is renewable, because using it today does not mean it stops tomorrow. There are many experimental stations around the world for wave energy, but no large and successful results yet.

Natural sources that contribute to ozone depletion include volcanic eruptions, which release sulfur dioxide and ash into the atmosphere. These substances can react with ozone in the stratosphere, leading to its destruction. Additionally, certain types of bacteria in soil and oceans can produce nitrogen oxides, which can also contribute to ozone depletion.

Carbon dioxide and methane are two greenhouse gases. They trap infrared heat rising from the earth's surface and help to keep the earth warm enough for life. If they were not around, the earth would be too cold for life.

The hydrosphere is most directly affected by the melting of the ice caps, as this process leads to an increase in global sea levels and affects ocean salinity and currents. Additionally, the cryosphere is impacted by the loss of ice cover, which in turn affects climate patterns and the Earth's energy balance.

Volcanic activity releases carbon dioxide into the atmosphere, contributing to the greenhouse effect and global warming. However, the amount of carbon dioxide released from volcanic eruptions is much lower compared to human activities like burning fossil fuels.

This phenomenon is called convection. As warm air rises, it cools down and becomes denser, causing it to sink back down. This continuous cycle is responsible for many weather patterns and is essential for distributing heat around the Earth.

Not necessarily. Some areas will experience severe flooding from time to time, but other areas will suffer more prolonged droughts. Excessive flooding is unlikely to result in productive storage of water.

Yes they both absorb infrared heat rising fron the surface of the earth, keeping the planet warm.

Water vapour can not build up in the atmosphere. When the air can't hold any more, it falls as precipitation (rain) of some kind. Carbon dioxide, on the other hand can, and is building up in the atmosphere because of human activity. This is leading to global warming and climate change.

The US National Climate Report 2013 predicts more frequent and more intense Midwest heat waves in the next ten or twenty years. Degrading air and water quality will threaten public health. Serious rainstorms and floods will be more common, and existing risks to the waters of the Great Lakes will be increased.

The three human solutions for limiting global warming are transitioning to renewable energy sources, implementing energy efficiency measures, and promoting sustainable practices such as reforestation and promoting green transportation.

Global warming can cause a rise in sea levels, which can lead to higher high tides and an increased risk of coastal flooding. The warming also affects ocean currents and can alter tidal patterns in some regions.

Global Warming is the cause of a lot of things and erosion may be increased in certain areas from global warming. As we know global warming will increase the planets temperature. Down in Antarctica, where it is all ice this is not good. So the ice melts as it does in plenty of other polar regions where the water has warmed. The water levels rise and begin to erode the beaches and land very slowly, but none the less it does increase. That's why dredging must be done to keep the beaches there, even though they do dredge even if global warming wasn't a problem. This is one way that i know of his global warming affects erosion.

Some buses are electric, and the CO2 emitted by their operation would come from coal fired power plants. West coast electric buses would receive hydrologic power, emitting very little CO2.

Most buses are diesel powered, and average about 6 mpg. Since automobiles get about 20 mpg, a bus needs to carry 4 passengers to break even. More than that and the bus gains in efficiency over the typical passenger automobile. One gallon of fuel emits close to 20 pounds of CO2, even though the fuel itself weighs only 6.25 pounds. This is because the carbon in the fuel combines with oxygen in the air--a LOT of it.

So 20 pounds per gallon times a gallon every six miles equals 3.3 lbs per mile. The US Federal Transit Authority estimates each bus averages 37,000 miles per year. So that amounts to 123,000 lbs (62 tons) of CO2 per bus per year.

For the next part of the question we need to know how many buses there are. There are 450 to 480 thousand school buses in the US (close to half a million). The US probably has fewer buses per capita than most nations on earth, which rely more heavily on public transportation.

Carbon dioxide in the atmosphere is not a concern as long as the amount remains fairly constant, so that it helps sustain life and maintain our temperatue at a comfortable level, suitable for human existence. Because carbon dioxide is a greenhouse gas, the present rapid rise in its atmospheric concentration is a concern because it is leading to global warming and climate change.

A warmer world might even sound desirable, but the long-term global trend to higher average temperatures poses a real risk to our economic and social well-being, as well as to the native creatures with which we share the planet.

Climate change is causing sea levels to rise. Not by much so far, but this is only the start. Higher sea levels, combined with the greater storm surges associated with climate change, will force people to abandon some prestige coastal properties. The inundation of New Orleans should have been a wake-up call, but many see this as a special case with no relevance elsewhere. Rich agricultural coastal flood plains will become salinated and unproductive.

Floods will become more frequent and more severe in some areas, while droughts will similarly become more frequent and more severe in others. Analysis of hurricane activity shows that severe hurricanes are becoming more frequent and more destructive, as a result of increased atmospheric thermal energy. Frequent storm damage to properties will cause insurance premiums to rise until some can no longer even afford to insure their houses.

Wildlife will suffer from loss of appropriate habitat and from heat stress. Some corals will die back as sea levels rise and they no longer receive sufficient sunlight, while others will be bleached by the rising temperatures and acidity.
