Document Summary
Since the 19th century, the average global temperature has increased by 0. 6 +/- 0. 2 degrees celsius. Warmest years since 1850 have been the recent years. Strong consensus that increase in greenhouse gases is from human activities (forestry and methane emission from livestock) Melting of ice in the arctic: permafrost melting, landslides, safety of ice roads. Food: crop yields decline as temperature increases. Water: melting of mountain glaciers, decreases in water availability, sea level rise. Globally: sea level rise of 0. 1-0. 2m per century during the past 100-200 years. Sandstone is soft rock: potential for severe erosion. Estuaries and marshes are at risk of becoming covered in water. Reduced sea ice cover in the gulf of st. lawrence. More wave action during the winter months that could bring ice chunks up onto the land (ice ride up) Increased storminess and storm surges, increased erosion that may cause damage to the coastline.
