Week 3
This week examined the more recent changes due to anthropogenic actions. According to the American Geophysical Union, climate change observations include increasing air and sea temperatures, sea level rise, decreasing expanse of Arctic sea ice, atmospheric water vapour, and a reduction in mountain glaciers, snow cover and permafrost.
The largest threats from these changes are increased temperatures, increased precipitation and higher coastal high water level, for example the current flooding around Cornwall.
It was interesting to see that carbon emissions have increased in developed and emerging regions due to burning fossil fuels, and some developing countries due to deforestation. However the emissions per capita haven’t increased as dramatically as the overall increase, suggesting that the rapid increase in human population is a cause of this increase.
