Report on Emissions |

| From IPCC SRES: |
|
|
|
|
|
|
|
| “Each storyline was
characterized initially by two |
||||||
| quantitative
‘targets,’ namely global population (15, |
||||||
| 10,
and 7 billion by 2100 in scenarios A2, B2, and |
||||||
| both A1 and B1,
respectively) and global gross |
||||||
| domestic
product (GDP) by 2100 (in 1990 US dollars, |
||||||
| US$550
trillion for A1, US$250 trillion for A2, |
||||||
| US$350
trillion for B1, and US$250 trillion for B2).” |
||||||
|
|
| Compare the above with current population of 6.3 |
|
| billion
and GDP of US$32 trillion. |
