Global warming is when the earth heats up (the temperature rises). It happens when greenhouse gases (carbon dioxide, water vapor, nitrous oxide, and methane) trap heat and light from the sun in the earth’s atmosphere, which increases the temperature.
The greenhouse effect is when the temperature rises because the sun’s heat and light is trapped in the earth’s atmosphere. This is like when heat is trapped in a car.
Greenhouse gasses are gasses are in the earth’s atmosphere that collect heat and light from the sun. With too many greenhouse gasses in the air, the earth’s atmosphere will trap too much heat and the earth will get too hot.
The global warming is not natural. People are causing it.
Water vapor is the most important, abundant greenhouse gas, but to fight global warming nations must focus on controlling CO2.
Humans are pouring carbon dioxide into the atmosphere much faster than plants and oceans can absorb it.
Global warming and the ozone hole are two different problems.
Average temperatures have climbed 0.8 degree Celsius around the world since 1880, much of this in recent decades.
Arctic ice is rapidly disappearing, and the region may have its first completely ice-free summer by 2040 or eaven earlier.
Polar bears and indigenous cultures are already suffering from the sea-ice loss.
Coral reefs are highly sensitive to small changes in water temperature. Some areas seeing bleach rates of 70 percent.
More than a million species face extinction from disappearing habitat, changing ecosystems, and acidifying oceans.
In the future, warming could become uncontrollable by creating a so-called positive feedback effect. Rising temperatures could release additional greenhouse gases by unlocking methane in permafrost and undersea deposits, freeing carbon trapped in sea ice, and causing increased evaporation of water.
Industrialization, deforestation, and pollution have greatly increased atmospheric concentrations of water vapor, carbon dioxide, methane, and nitrous oxide (greenhouse gases). These gases persist in the atmosphere for years, but not in a such hight concentration.
If spose such emissions were eliminated today, it would not immediately stop global warming.
Sea level could rise between 18 to 59 centimeters by century’s end.
Glaciers around the world could melt, causing sea levels to rise.
What can we do to stop global warming?
We can do carpooling. Carpooling is driving with someone to a place that you are both going to. This minimizes the amount of greenhouse gases put into the air by a car an save time, gazoline and money.
We can be more carefully about leaving things turned on like the television, computer, and the lights when we are not useing them. To leave them in sleep mode or snadby regime is not enought. You have to turn them off when you do not need.
It’s much more better and healthy to taking time away from the television and computer, and instead, and spending more time outdoors. This helps us to be healthy and our planet out a lot.
Now, more look after their carbon footprint and even riding busses, walking to school, and riding their bikes to lower the amount of greenhouse gases in the air.
Planting trees and recycling also helps.
Many things, such as hairspray and deodorant, now are made to have less of an impact on the atmosphere. Imported products produce CO2 emission within the delivery process.
The electricity is not as clean as we thought. The electricity we use everyday comes from power plants that still uses fossil fuels. So replace a regular incandescent light bulb with a compact fluorescent light bulb. Replace other electricity consumers with more nergy efficiency.
Use programmable thermostat.
Wrap your water heater in an insulation blanket.
Move your fridge and freezer away from cooker or boiler.
Replace your old single-glazed windows with double-glazed PVC or wood framed.
Get a home energy audit. You can save energy up to 30%.
Insulate and weatherize your home and replace old heating/cooling systems with energy efficiency.
Take a shower instead of a bath. It use less hot water.
