Don't worry, berretta - it would probably be after you and I are gone. Current estimates are around +4C-5C by the end of the century if we keep on the current emissions path. But it could be more. Most places would see serious problems by mid-century. The last decade would probably have a sudden sea level rise by some projections, which won't help matters.
BTW - if you ever learn how to follow hyperlinks you could check the secondary source I gave and that source leads to the primary source.
I was mistaken about Australia's commitment being a 5% cut on those of 1990. That applied to most of the rest of the developed world. We got a get out of gaol card and made a commitment to keep emissions below 108% of 1990, as this overview describes:
Australia made an international commitment in December 1997 at Kyoto (Conference of the Parties COP3) to limit its greenhouse gas emissions growth to 108 per cent of its 1990 baseline, which equates to nearly a 30 per cent reduction from its 'business as usual' projections. Australia was one of three countries�the other two being Norway and Iceland�granted an increase of its emission levels on its 1990 base; an argument won on the concept of 'differentiated targets' based on a country's particular economic circumstance. In contrast, this compares to developed countries collectively agreeing to reduce their aggregate emissions of greenhouse gases by at least 5 per cent from 1990 levels in the first commitment period 2008�2012.
The Dept of Climate Change and Energy Efficiency reports that we will remain within that limit on average through to 2012, but without action emissions would grow to 690 Mt CO2-e in 2020, or 24 per cent above 2000 levels.. There's a chart on that page showing the 1990 levels, the level as at 2010 and the projected growth to 2020 in the absence of action. It also shows the projected amounts that will need to be offset.
We and the rest of the world will need to agree to and achieve greater reductions over coming decades.
If anyone is interested in reading more - there is a heap of info around, way too much info to post it all on HC. (A bit like the science that a few people don't want to know about.)
