Human responses to global warming free
Global warming. The largest human influence has been the emission of greenhouse gases such as carbon dioxide, methane, and nitrous oxide. In view of the dominant role of human activity in causing it, the phenomenon is sometimes called anthropogenic global warming or anthropogenic climate change .
4 Human Consequences and Responses. The human consequences of global change could then be defined as the difference between the state of humanity at the end of one grand scenario and the state of humanity at the end of a base case or reference scenario with a

Global warming is the current increase in temperature of the Earth's surface (both land and water) as well as it's atmosphere. Average temperatures around the world have risen by 0. 75C (1. 4F) over the last 100 years about two thirds of this increase has occurred since 1975.
Over the years, the models of attribution science have become more sophisticated, and, in addition to attributing global warming to human caused emissions, they are also able to determine the contributions of global warming to extreme events (like floods, heat waves, storms, etc).
Conclusion. The global warming witnessed over the past 150 years matches nearly perfectly what is expected from greenhouse gas emissions and other human activity, both in the simple model examined here and in more complex climate models. The best estimate of the human contribution to modern warming is around 100.
