Climate-change Peer Review
Even small increases in Earth’s temperature caused by
climate change can have severe effects. The earth’s average temperature has gone up 1.4° F over the past century and is expected to rise as much as 11.5° F over the next. That might not seem like a lot, but the average temperature during the last Ice Age was about 4º F lower than it is today. Rising sea levels due to the melting of the polar ice caps (again, caused by
climate change) contribute to greater storm damage; warming ocean temperatures are associated with stronger and more frequent storms; additional rainfall, particularly during severe weather events, leads to flooding and other damage; an increase in the incidence and severity of wildfires threatens habitats, homes, and lives; and heat waves contribute to human deaths and other consequences. hile consensus among nearly all scientists, scientific organizations, and governments is that
climate change is happening and is caused by human activity, a small minority of voices questions the validity of such assertions and prefers to cast doubt on the preponderance of evidence.
Climate change deniers often claim that recent changes attributed to human activity can be seen as part of the natural variations in Earth’s
climate and temperature, and that it is difficult or impossible to establish a direct connection between
climate change and any single weather event, such as a hurricane
