Another trip to cloud cuckoo land. How do they plan to accurately measure all the so-called emissions and get all parties to agree with the results anyway? Time to return to reality and stop wasting time and effort on non-existent supposed remedies.

A new paper published in Nature has highlighted a fundamental mismatch in the way greenhouse gas emissions are measured which could mean that Net Zero could be met in one definition up to five years ahead of the other, says the Met Office .
The IPCC report shows that global temperature will stop increasing when we reach ‘net zero’ emissions of CO2. [Talkshop comment -*claims*, not shows].
To achieve this, human activity cannot put more CO2 into the atmosphere than it removes – we need to massively reduce our emissions, with some removal of CO2 to help areas which are really hard to decarbonise.
This sits behind the principle of Net Zero, which countries including the UK hope will be reached by 2050.
The paper by Gidden et al, highlights the differences between the two key greenhouse gas accounting systems: one which underlies the IPCC statement that net zero will halt global warming; and the other from how nations produce a National Greenhouse Gas Inventory (NGHGI) to report to the UNFCCC (United Nations Framework Convention on Climate Change).
Professor Chris Jones, who is the Met Office’s lead on carbon budgets, was asked to write a discussion document alongside the paper.
Jeopardy
Chris Jones said: “Both of the key systems for measuring greenhouse gas emissions work well on their own. But there is a challenge when they have to work together in one view. It’s a little like having a bank account and spending in one currency, while trying to save in another. Both currencies work fine on their own, but merging the two together requires an exchange rate mechanism otherwise you risk financial jeopardy by spending beyond your means.”
