INTRODUCTIONThis time we present global warming as several animals in the world have lost their habitat it happens more often in antartica and forests

That is global warming

Global warming is primarily a problem of too much carbon dioxide (CO2) in the atmospherewhich acts as a blanket, trapping heat and warming the planet. As burn fossil fuels like coal, oil and natural gas for energy or cut down and burn forests to create pastures and plantations, carbon accumulates and overloads our atmosphere. The Consequences of a Warming World

The only way to explain the pattern is to include the effect of greenhouse gases (GHGs) emitted by humans.Human influence has been detected in warming of the atmosphere and the ocean, in changes in the global water cycle, in reductions in snow and ice, in global mean sea level rise, and in changes in some climate extremes

The ranges of these estimates arise from the use of models with differing sensitivity to greenhouse gas concentrations.
