Sharp rise in Arctic temperatures now inevitable – UN
Temperatures likely to rise by 3-5C above pre-industrial levels even if Paris goals met
Sharp and potentially devastating temperature rises of 3C to 5C in the Arcticare now inevitable even if the world succeeds in cutting greenhouse gas emissions in line with the Paris agreement, research has found. Winter temperatures at the north pole are likely to rise by at least 3C above pre-industrial levels by mid-century, and there could be further rises to between 5C and 9C above the recent average for the region, according to the UN. Such changes would result in rapidly melting ice and permafrost, leading to sea level rises and potentially to even more destructive levels of warming. Scientists fear Arctic heating could trigger a climate “tipping point” as melting permafrost releases the powerful greenhouse gas methane into the atmosphere, which in turn could create a runaway warming effect.www.theguardian.com/...

Even if all carbon emissions were to be halted immediately, the Arctic region would still warm by more than 5C by the century’s end, compared with the baseline average from 1986 to 2005, according to the study from UN Environment. That is because so much carbon has already been poured into the atmosphere. The oceans also have become vast stores of heat, the effect of which is being gradually revealed by changes at the poles and on global weather systems, and will continue to be felt for decades to come. The findings, presented at the UN Environment assembly in Nairobi on Wednesday, give a stark picture of one of the planet’s most sensitive regions and one that is key to the fate of the world’s climate.www.theguardian.com/...

A manifesto for tackling the climate change crisis
As thousands of pupils strike over the catastrophe facing the planet, we demand a state of emergency be called
The burden for creating the change we need to see in the world has sadly fallen upon us and our peers around the world, unified in our common struggle to address the climate crisis. Failure is not an option, that’s why we’re demanding the following
