“Sustainability creates and maintains the conditions under which people can exist in harmony with nature, that permit fulfilling the social, economic and other requirements for our lives in the present, and for future generations.”
Where is global warming going?
Atmosphere 2.3%, Continents 2.1%, etc…
Fisheries:
54% fully exploited
20% moderately exploited
17% overexploited
7% under exploited
Biodiversity Under Climate Change
By 2050, 15-37% of species, depending on the part of the world, will be committed to extinction because of climate change alone.
The Tipping Point
Many studies in the last 25-years suggested that the tipping point of 400 ppm of atmospheric carbon dioxide would be reached by around 2050.
We passed 400 ppm, in late March 2014 for the first time.
