The issue of global warming and the greenhouse effect

Plants convert carbon dioxide into oxygen during photosynthesis, the process they use to make their own food.

short note on greenhouse effect and global warming

Our citizens need to be educated as to likely changes and how best to deal with the changing conditions. As they hit the soil and surface waters, those rays release much of their energy as heat.

greenhouse effect facts

Carbon dioxide is released when we use fossil fuels, such as coal, oil and natural gas. While the dominant gases of the atmosphere nitrogen and oxygen are transparent to infrared, the so-called greenhouse gasses, primarily water vapor H2OCO2, and methane CH4absorb some of the infrared radiation.

Factors influencing these changes probably included fluctuations in the radiation output from the sun, and changes in circulation and overturning in the oceans.

What is global warming

A chance to turn truth into real action and bold solutions. Burning releases CO2 into the atmosphere much the same as respiration does. Higher CO2 allows plants to grow faster more CO2 enhances photosynthesis. Has the climate shifted? Many scientists agree that the damage to the Earth's atmosphere and climate is past the point of no return or that the damage is near the point of no return. But what exactly does it mean? So, the question is: what can you be doing to reduce your impact on the environment? The IPCC produced major assessment reports in , , , and To understand global warming, it's first necessary to become familiar with the greenhouse effect, though. Some of the heat then radiates back out into space. Certain gases in the atmosphere resemble glass in a greenhouse, allowing sunlight to pass into the 'greenhouse,' but blocking Earth's heat from escaping into space. Incoming solar radiation warms the car's interior, but outgoing thermal radiation is trapped inside the car's closed windows. Sea level is expected to rise closer to 3 feet during the coming century. How is the climate expected to change in the future?

Sea level rose about 1 foot during the last century, mostly from thermal expansion of the oceans. Weaker IR radiation, however, has difficulty passing through the glass walls and is trapped inside, thus warming the greenhouse.
