Time lapse satellite imagery shows the Great Lakes icing over in one of the coldest winters in memory. Climate Progress. What's the target for solving climate change? | Environment. Climate change targets can be highly confusing.
There are various types of targets, and lots of uncertainty about how each target could be met and what would happen if it was. Let's look at the three main types of target in turn. Temperature targets Ultimately, temperature rise is the thing that matters, as warming causes all the other symptoms of climate change. There's no agreement about what constitutes a "safe" temperature rise but in the hope of reducing the risks to an acceptable level – and in particular to try and limit the chance of crossing "tipping points" in the climate system – most of the world's nations have signed up to a non-legally binding target of limiting temperature rise to 2C above pre-industrial levels.
However, this target isn't universally accepted. Temperature targets can refer either to the level at which the global temperature stabilises (e.g. levelling off and remaining at 2C) or to a peak (e.g. reaching 2C and then falling to a lower level). Emissions targets.
