The rise in the average temperature of Earth's atmosphere and oceans is what we called “global warming”. Since the time immemorial, Global Warming has always been a great issue of which one of the major cause that is continually to be blame is us, humans. For centuries, this environmental issue continue to exist and worsen. Alarming as it is as the earth is now gradually deteriorating as shown in the unusual climate patterns, news all over the places and some documentations presented by the concern citizens.

Global warming is changing our economy, health and communities in diverse ways. When it comes to connecting the dots between climate change, extreme weather and health, the lines are clear. The earth is saying something with record heat, drought, storms and fire. Scientists are telling us this is what climate change looks like.

Scientists project global warming to continue at a rate that is unprecedented in hundreds of thousands or even millions of years of Earth’s history. They predict considerably more warming in the 21st century, depending on the level of future greenhouse gas emissions. For a scenario (possible situation) assuming higher emissions—in which emissions continue to increase significantly during the century—scientists project further warming of 2.4 to 6.4 Celsius degrees (4.3 to 11.5 Fahrenheit degrees) by the year 2100. For a scenario assuming lower emissions—in which emissions grow slowly, peak around the year 2050, and then fall—scientists project further warming of 1.1 to 2.9 Celsius degrees (1.9 to 5.2 Fahrenheit degrees) by the year 2100. Melting polar ice and glaciers, as well as warming of the oceans, expands ocean volume and raises sea level, which will eventually flood some coastal regions and even entire islands. Patterns of rainfall are expected to change, with higher latitudes (closer to the poles) projected to receive more rainfall, and...
