IPCC climate change report – what it means
The IPCC is a team of scientists – more than 2,000 of them – that the United Nations asks for unbiased updates on climate change.
After slogging away for more than 2 years, they've just released their latest work. In a nutshell, climate change is looking bad. Like no-more-coral-reefs bad. But we can still get out of this mess.
What's the worst-case scenario?
The report is frank. We can't let the planet warm by more than 1.5°C. Even an extra half a degree puts millions more people at risk of flooding. The risks to nature become very high too. Insects that pollinate our food are almost twice as likely to lose their habitat at 2°C. And we can all but say goodbye to the coral reefs at that temperature.
Is the 2°C warning new information?
We already know that limiting global warming to 1.5°C is the best chance we have of stopping disastrous changes to the climate. The new revelation, is the shocking amount of change that just half a degree more can cause.
How are we doing – are we on track to beat this?
Bluntly, no. We’ve already hit around 1°C of warming and are currently on course for a devastating rise of more than 3°C.
It doesn't help that governments are promising one thing and doing another. Like our government: it's fuelling climate change by supporting fracking, Heathrow expansion, road building and other polluting projects.
What's the good news?
We can still keep global warming below 1.5°C and stop runaway climate change. Right now it's difficult but not impossible to achieve – but we've got a small window of opportunity. Consider this the final call for serious action.
Success will mean cleaner air, lower sea levels, less flooding, fewer people forced from their homes and countries because of extreme weather, more access to water and more nature.
There are bonuses too. For example, schemes to reduce energy waste will lead to warmer homes and lower utility bills.
What do we need to do?
The report lays out several pathways of avoiding warming above 1.5°C. Essentially we need to produce much less planet-warming carbon pollution.
All of the paths require a much faster transition to electric cars. Reforestation is essential to them all too – trees suck carbon pollution out of the air. We need to double the area of forests in the UK.
And governments need to stop funding climate change. They're currently supporting planet-warming industries that dig up and burn coal, oil and gas. We need to ditch these fossil fuels as soon as possible and invest more in clean, renewable energy.
What can I do?
One simple but really important thing you can do now – is sign our petition against fracking. Fracking contributes to climate change, and the government is trying to force it on communities.
