Global Warming

ever since people start use vast ammount of electricity global warming has gone up. This is when the polar bears started to be affected. If global warming goes up it means the ice caps start melting, and that means the polar bears have nowhere to go.

Hope this has helped

Months, years or even centuries aren't helpful for thinking about earth's long history.

Because the time span of earth's past is so great,geologist use the geologic time scale to show earths history.

:they didn't discover much, but they use fossils,DNA,and reacher many things.:

Any climate scientist understands that the weather goes through cycles of different times scales. Almost all also recognize that we are perturbing the system strongly enough to cause a general warming globally with additional effects to precipitation regimes, for example.

Without greenhouse gases, Earth would be much colder and unable to support life as we know it. Greenhouse gases, like carbon dioxide and methane, trap heat from the sun and keep our planet at a temperature suitable for living organisms to thrive.

Both the atmosphere and ocean play important roles in shaping climate, but the ocean generally has a stronger effect due to its vast heat capacity and ability to store and transport heat. Ocean circulation patterns, such as El Niño and La Niña, can have significant impacts on global climate patterns, while the atmosphere primarily interacts with these oceanic influences to generate weather events.

If global warming continues, then glaciers and ice caps will melt causing rises in sea levels that will destroy island nations and causing flooding around low lying coastal areas of most countries. Rising temperatures will bring climate change, with weather events predicted to become more severe. Frozen land may become suitable for growing crops but large areas of warm countries, like Africa, may become desert and the people will suffer drought and famine. Some of this is already happening.

Greenhouse gases, such as carbon dioxide and methane, help to keep Earth warm by trapping heat in the atmosphere. This natural greenhouse effect is essential for sustaining life on Earth by maintaining a stable temperature. However, human activities have led to an increase in these gases, which has resulted in global warming and climate change.

1. Combustion of fossil fuels: Burning coal, oil, and natural gas for energy production releases carbon dioxide into the atmosphere.
2. Deforestation: Clearing land for agriculture, logging, or urban development reduces the number of trees that can absorb carbon dioxide through photosynthesis.
3. Cement production: The chemical process of making cement releases carbon dioxide as a byproduct, contributing to greenhouse gas emissions.

The stronger, or enhanced greenhouse effect is principally the result of human activities that increase the atmospheric concentrations of carbon dioxide and methane. these activities include burning fossil fuels such as coal, oil and natural gas, manufacturing cement and deforestation.

Coal is considered the worst fossil fuel for the environment due to its high carbon dioxide emissions when burned for energy, contributing significantly to global warming and air pollution. It also generates large amounts of ash and other pollutants that can harm ecosystems and human health.

Yes. This is part of the Milankovich Theory, which describes the collective effects of changes in the earth's movements upon its climate. A cycle of precession lasts 26,000 years and can contribute to climatic changes over periods of thousands of years. The combined effect of precession and other cycles can produce long-term cycles in the amount of warmth received from the sun, thereby triggering changes which, reinforced by changes in greenhouse gas levels, result in the ice ages. For the prediction of climate change in the twenty-first century, these changes are considered far less important than radiative forcing from increased greenhouse gas levels.

Snow storms can still occur in a warmer world due to the increased moisture in the atmosphere. Global warming can lead to more frequent and intense snow storms under certain conditions, but it depends on various factors such as temperature, humidity, and atmospheric patterns.

Greenhouses are designed to control the environment for plant growth by trapping heat and allowing sunlight in. This creates a warm and stable environment that is ideal for growing plants, extending the growing season, and protecting plants from harsh weather conditions. Greenhouses also help to regulate humidity and provide protection from pests and diseases.

The consequences of increased carbon dioxide in the atmosphere include global warming, leading to rising temperatures, sea level rise, melting ice caps, more extreme weather events, and disrupted ecosystems. This can have severe impacts on agriculture, water availability, and human health.

First of all, coal is an efficient and cheap fuel that allows us to generate as much electricity as we wish, as well as providing an easy method of smelting iron ore. There are many good things about coal, but the problems it creates can exceed those benefits, forcing us to look for alternatives.

Coal, and especially brown coal, is quite polluting. It produces particulate pollution, as well as dangerous sulphur dioxide and nitrous oxide gases. These can be filtered out, but traditionally have simply been vented into the atmosphere.

Most importantly, burning coal is bad because it adds large amounts of new carbon dioxide to the atmosphere. As carbon dioxide is a greenhouse gas, that leads to global warming, which is one of the most serious problems facing society in the twenty-first century. We need to replace our usage of coil and oil by alternative energy sources.

You can save water by taking shorter showers, fixing leaks, and only running the dishwasher or washing machine with full loads. To save energy when heating water, consider using a more energy-efficient water heater, insulating your hot water tank and pipes, and lowering the temperature setting on your heater.

Yes. The application of scientific knowledge has proven that global warming is real and has established that it is, amongst other factors, the result of human activities such as burning fossil fuels (coal, oil and natural gas).

No, oxygen is not the main cause of global warming. The main contributors to global warming are greenhouse gases such as carbon dioxide and methane, which trap heat in the Earth's atmosphere. Oxygen makes up about 21% of Earth's atmosphere and is crucial for life, but it does not directly contribute to global warming.

Greenhouse gasses is a gas in the atmosphere That absorbs and emits radiation. The primary greenhouse gasses in the earth's atmosphere are water vapor, carbone dioxide , methane, Nitrous oxide and ozone. Greenhouse gasses affect the earth by keeping the heat at earth making the ice melts which increase the water level. Making floods and many people will be killed.

The climate changes accompanying GHG emission can case droughts, severe weather, changes in growing seasons and changes in fish stocks in the ocean. This will in turn have impacts on human lives with everything from floods, forest fires, crop failure, famine to new diseases spreading more quickly. The effect will be that many people will die.However, you (specifically) may not be in that group.

One possible reason for the rise in the average air temperature at Earth's surface is the increase in greenhouse gas emissions, such as carbon dioxide and methane, trapping more heat in the atmosphere. This enhanced greenhouse effect leads to global warming and overall higher temperatures.
