We wanted to find out how much carbon and nitrogen is being released from the northern permafrost. Here’s the region’s first full greenhouse gas budget covering CO₂, methane, and nitrous oxide.

‘Breath emissions’ are around 0.05% of the UK’s total methane emissions.
If you own a diesel car with an AdBlue tank, your engine is programmed to not start once you run out of it. But Australia can handle the looming diesel engine additive shortage – if we don’t panic.
Targets for reductions in methane and other greenhouse gases should be guided by science, and set in line with the Paris deal.
Nitrous oxide is a potent greenhouse gas, 300 times more powerful than carbon dioxide. Global emissions of N2O are on the rise as a result of human activities — and their impact on ocean ecosystems.
No-one says reducing emissions from the agriculture sector will be easy. But it must be done, or farmers will suffer the most.
Agriculture is the dominant cause for the increasing N₂O concentrations. Emissions must be reduced if we hope to stabilise Earth’s climate.
Measurements and modelling have found nitrous oxide emissions, a greenhouse gas 265 times more potent than carbon dioxide, are significantly higher than previously reported.
The New Zealand government’s decision to partner the farming sector to encourage voluntary reductions in farm emissions failed to acknowledge that agricultural emissions also affect water quality.
