An Inconvenient Truth


The inconvenient truth, is truth that is causing us troubles; truth that if ignored would result into a catastrophe. We need to wake up to the inconvenient truth of global warming before it gets too late.“Al” Gore, is an environmentalist who served the United States of America as the 45th Vice President from 1993-2001 under President Bill Clinton.He’s an author,businessman and former journalist, he also has produced his own documentary titled, “The Inconvenient Truth”.


The majority of the landmass and vegetation today lies above the equator, unfortunately if the world remains as careless, there won’t be much of it at all. 40% of the people in the world today get their water from the oceans, but oceans nowadays are drying up day by day because more heat is absorbing the water ; which is because of global warming. On the other hand, growing population on earth also affect global warming by allowing greenhouse gasses to clog up the atmosphere with carelessness. Population on earth can grow freely without any harm by avoiding any unneeded pollution, such as allowing greenhouse gases to wonder freely affecting our atmosphere which results into global warming.


I’ve personally found this documentary intelligent, humorous and informative. It was well put, it suited different audiences; such as the cartoon scene and then there was the informative graph. Both scenes portrayed the same idea, but in different ways for the different audience. It was perfect!

An Introduction to Global Warming


Global warming is basically classified as the environmental climate change, increasing the temperature on earth because as the earth is getting hotter, disasters like hurricanes, droughts and floods are getting more frequent. One of the main problems of global warming is not how much the world is warming but how fast it is warming. Carbonic emissions and other harmful gases released from fuel exhausts and greenhouse emissions disrupt the ozone layer,

increasing global temperature and causing sea levels to rise due to thermal expansion,melting of glacier sheets,warming of the ocean surface, leading to increased temperature stratification, ravaging crops,flooding coastlines and oceans.

 

The ocean which serves as a sink for carbon dioxide, takes up more than would otherwise remain in the atmosphere; therefore increased levels of CO2 have led to ocean acidification. Furthermore, as the temperature of the oceans increase, they become less able to absorb excess CO2. Global warming is projected to have a number of effects on the oceans.
