A review study on global warming and climate change

Convincing evidence that the Earth's climate is experiencing substantial and worrisome, changes has gathered quickly in recent years, particularly over the last three decades. Instead, global warming is a reality verified by a large body of observations from many various sources. Indeed, the emphasis of study has now moved from trying to prove the presence of global warming to efforts to identify its causes. Although the precise amount of damage from global warming may be impossible to estimate today, it can be stated with certainty that the negative consequences of global warming on climate will substantially exceed the potential advantages. The likelihood is very strong that human produced greenhouse gases, with carbon dioxide the main culprit, are the primary cause of clearly established global warming and climate change today. This review article will provide convincing evidence that global climate change induced by global warming is already occurring and is need of our urgent attention. The conclusion that there is significant warming of the Earth's surface is not based mainly on theoretical models, although these models do succeed in reproducing the current datasets with increasing success. Much can be done today to minimize the consequences of global warming and the related climate change. Difficulties in resolving the issue are not caused mainly by unavailable technology, but by the absence of adequate incentives to adopt the new technologies more aggressively.
