So does it really matter that driving a car and using electricity adds more carbon dioxide to the atmosphere? So what is this greenhouse effect?
When we say that the conditions on Earth are conducive for presence of life, the average temperature prevailing on the planet has a crucial role to play.
Their objective of big government robbing us of more of our freedoms and spending trillions of dollars on a made-up problem has been exposed. Heat, just like radio-waves, has different frequencies, and clouds, just like a radio receiver, block certain frequencies of heat and allow other frequencies through.
Carbon dioxide causes global warming because it contributes to the so-called greenhouse effect. Hansen made many other predictions, including stronger hurricanes related to global surface temperatures.
Winter is a good opportunity to observe the greenhouse effect in action. As if to confirm this, climatedepot. There is no doubt about the basic science behind global warming. Some of the most abundant greenhouse gases include water vapor, carbon dioxide, methane, etc.
Facts and Myths Basically, the thermal radiations coming from the Sun are reflected back to the space after they come in contact with the surface of the Earth. That trapped energy, or heat, serves to keep our planet warm. More recently, the concentration of these gases has increased by a significant extent.
However, certain gases in our atmosphere, such as carbon dioxide, methane and water vapor, work like a blanket to retain much of that heat. Scientists have known and understood this for over years, and it has been confirmed in laboratory experiments. The amount of carbon dioxide in the atmosphere has been climbing to where today it is 30 percent greater thanyears ago.
Humans have further increased the levels of greenhouse gases in the air by changing the landscape. Of course, this is a simplified explanation of global warming, but the basic story I have just told you is correct. Simply put, global warming is an abnormal increase in the average near surface temperature of the planet.
Climate researchers and policymakers should adopt the more modest forecasts that are consistent with observed temperatures. The other was that Canadian scientists studying the effect of climate change on Arctic ice from an icebreaker had to suspend their research, when their vessel was called to the aid of other ships trapped in the thickest summer ice seen in Hudson Bay for 20 years.
Plants convert carbon dioxide into oxygen during photosynthesis, the process they use to make their own food. The more clouds there are, the warmer it stays overnight. But there can be too much of a good thing. In my next segment, I will examine why scientists are convinced that if we are not careful, the earth will warm 2 or more degrees, and I will examine what the consequences of this will be.
Overall, the greenhouse effect is a perfectly normal phenomenon, which is necessary for the existence of life on the Earth. Hansen testified before the Senate Committee on Energy and Natural Resources and asserted a "high degree of confidence" in "a cause-and-effect relationship between the greenhouse effect and observed warming.
Scientists refer to these pollutants as greenhouse gases. When there are clouds, some frequencies of heat are blocked from escaping into space, keeping it warmer.Feb 28, · By planting more trees helps in reducing global warming as plants utilize carbon dioxide during the process of photosynthesis, which is the main cause of Global warming.
To learn more about global warming and greenhouse effect, visit BYJU’S. Most scientists agree the main cause of the current global warming trend is human expansion of the "greenhouse effect" -- warming that results when the atmosphere traps heat radiating from Earth toward space.
Explainer: Global warming and the greenhouse effect. Greenhouse gases trap heat on Earth. Agnieszka Biskup. global warming The gradual increase in the overall temperature of Earth’s atmosphere due to the greenhouse effect.
This effect is caused by increased levels of carbon dioxide, chlorofluorocarbons and other gases in the air. The greenhouse effect occurs is often referred to as the greenhouse effect because a greenhouse works in much the same way.
not the cause of global warming, though that goes against the. Guest post by Kevin Judd Climate scientists are telling us that gases like carbon dioxide are causing global warming. Carbon dioxide is produced when petrol is burned in your car engine, or when coal and gas are burned at power-stations to make electricity.
Carbon dioxide causes global warming because it contributes to the so-called greenhouse effect. GREENHOUSE EFFECT & GLOBAL WARMING - The internet as the primary source of information - The internet as a resource - Use “reputable” web sites.Download
