Global warming is the temperature of Earth 's surface, oceans and atmosphere going up over tens to thousands of years. Sea level is rising for two reasons. One reason is because of ice on the land, like Greenland , melting into the sea. The other reason is because of water getting bigger when it gets warmer. Many cities will be partly flooded by the ocean in the 21st century. Global warming is mostly because of people burning things, like gasoline to make cars go and natural gas to keep houses warm.

Global Warming - Definition, Facts, Causes and Effects of Global Warming | NRDC
Global Warming is the increase in Earth's mean surface temperature because of the effect of greenhouse gases. These gases absorb longwave radiations and warm the atmosphere, and this process is called a Greenhouse effect. It had led to many changes on the planet, such as a rise in sea level; massive melting of snow and land ice, elevated heat content of the oceans, increased humidity, change in the timings of seasonal events, and many others. For both land and ocean, the global mean surface temperature indicates warming of 0. Hence, it is seen that the rate of warming approximately doubled for the last half of that duration 0. The impact of any GHG is based on the magnitude of the rise in its concentration, its duration in the atmosphere and the wavelength of radiation that is absorbed. Carbon dioxide is the GHG which is present in the largest concentration in the atmosphere.
Global Warming 101
There has been much discussion recently about global warming. Also known as climate change, global warming has become an issue that is a major concern to the world we live in today. With each day that passes, the surface of our earth becomes hotter, and the biggest and most considered cause of global warming is deforestation and greenhouse effect.
Many people across the country have been convinced that global warming is affecting us more and more with each passing day. Because of numerous campaigns by the likes of famous politicians such as Al Gore, the common citizen has been convinced that drastic action needs to be taken in order to stop global warming. However, contrary to popular belief, a large number of distinguished scientists and engineers do not agree that drastic actions on global warming are needed.
