Cutting emissions, ramping up renewable energy,
adapting to a new way of life and sucking carbon dioxide out of the
air: recent reports from the Intergovernmental Panel on Climate
Change (IPCC) appear to offer a number of ways to limit the scale
and seriousness of climate change.
Which are the real climate solutions, and which are
pretty risky bets? Here's what the IPCC says about what will and
won't work when it comes to fixing the climate.
The two degree target
What we can do to curb the
impacts of climate change is the topic of the
third in a series of recent reports from the IPCC. But
when we talk about limiting climate change, what do we really
The idea that we should avoid "dangerous" interference
with the climate has been around for
a while. But at the UN climate summit in
Cancun in 2010, governments made the goal of keeping
warming to no more two degrees Celsius above pre-industrial levels
an official target.
The world has already warmed by 0.85 degrees over the
industrial period and if emissions stay high, we're on course for
more like three to five degrees by 2100, the IPCC
noted in its September report.
In other words, without efforts to reduce warming,
we're set to fall a long way short of the target.
