Document Summary

Since 19th century, average global temperature has increased by: 0. 6 c 0. 2 c. The 19th century until the first half of the 20th century was marked by colder temperature. However, there is a current increase in temperature throughout the 21st century. The rate at which the temperature is increasing is astonishing. Strong consensus that increase in greenhouse gases (ghg) is: from human activities: impact from forestry, methane emissions. What are the implications of climate change on the cryosphere. Melting of ice in the arctic: melting of mountains and glaciers, which could disappear by mid-century, melting of permafrost, which leads to landslides, ice roads. As the temperatures rise, there is an effect on food, water, ecosystems, extreme weather events, and a risk of abrupt and major irreversible changes. As the temperatures increase, there is an impact on human health, communities and infrastructure, resource industries, service industries, and security and trade.
