At this point, there is little doubt that climate change has occurred as the result of human activity--over 97 percent of scientific experts agree that this is the case. However, there is debate about the best way to deal with climate change now that its impacts are becoming apparent through issues such as extreme weather and a loss of habitable land. One potential approach is through mitigating climate change, which involves reducing greenhouse gas emissions and stabilizing their levels in the atmosphere. While many support this approach, questions exist about how effective this plan will be at reducing or even reversing the impacts of climate change and who should be responsible for paying for and implementing these efforts. This title examines these pressing questions from a range of perspectives, including those of scientists and experts in global finance and politics.
