The paper critically looks into the science of climate change. On the same context, the paper discusses using specific examples the climate skeptics’ criticisms of the film Inconvenient Truth starring former U.S. Vice President Al Gore. The massage of the movie is very clear; global warming is entirely caused by humans and the consequences are devastating. Science has been defined as knowledge attained through practice or study covering general truths of the operation of general rules and laws that has been systematically collected, tested via scientific methods and the results can be reproduced. Observation as well as carrying out experiments to attempt to explain and describe natural phenomenon is an integral part of science. Climate change refers to alteration from one climatic condition to another usually beyond the present conditions due natural or manmade effects. The phenomenon has been thought to be the greatest environmental challenges of our time with a higher probability of affecting human as well as other living organisms (Gleick, 2001)
