What effect does every average earth temperature rising have?
It’s best talking now about “global climate change”… Statistics say the average temperature of the Earth’s surface has increased by 0.74 C over the past century, from 1906 to 2005, and is expected to further rise by 1.1 to 6.4 C by the end of the 21st century. The rise of global average temperatures since the mid-20th century is mainly caused by the increasing atmospheric concentrations of greenhouse gases, chiefly consisting of carbon dioxide, methane and nitrous oxide, due to human activities, such as fossil fuels and land use such as deforestation. Here are some consequences: – During the 20th century, sea level rose about 15 cm (6 inches) due to melting glacier ice and expansion of warmer seawater. Models predict that sea level may rise as much as 59 cm (23 inches) during the 21st Century, threatening coastal communities, wetlands, and coral reefs. – Arctic sea ice is melting. The summer thickness of sea ice is about half of what it was in 1950. Melting ice may lead to changes in
