The Observer, 30 August 2020:
Global warming is worse than portrayed by Robin McKie (“Revealed: Earth loses trillion tonnes of ice in less than 30 years”, News). Nasa’s Goddard Space Flight Center estimates that the world has warmed by just over 1C since 1880, but temperatures are higher over land than water. Thus Europe has warmed by 2C, and the Arctic by more than 3C.
Loss of ice leads to loss of reflectivity, which aggravates the warming, but wildfires in the Arctic are also dirtying the snow, which increases heat absorption. This can only end badly. Melting of the permafrost has the potential to double the amount of methane in the atmosphere. If the Arctic seabed starts to give up the vast amount of methane stored as clathrates, global warming will become irreversible and it is game over for human civilisation. Politicians seem transfixed by this unfolding tragedy. Their latest excuse is the pandemic, but they have done almost nothing over the past 30 years. The Kyoto protocol was designed to reduce carbon emissions but since 1990, the baseline year for Kyoto, annual emissions have increased by 50% globally. The UK is hosting COP26 (the UN Climate Change Conference of the Parties) next year. We can only pray that the government recognises the awesome responsibility it carries.

The failure of the government to protect our rivers extends beyond the Environment Agency (The government is looking the other way while Britain’s rivers die before our eyes, 12 August).
Defra’s Clean Air Strategy 2019 focused on the need to control emissions from agriculture, notably ammonia, which is a precursor for small particulates (PM2.5). Ammonia is released from nitrogen-containing fertilisers, and manure/slurry spread on to fields, particularly during the spring. Releases of ammonia can be reduced significantly by choosing the right sort of fertiliser, and injecting the manure into the soil. This would also protect rivers.
Yet the list of financial incentives offered to farmers in the government’s current agriculture bill does not include air pollution. This is a glaring omission, as the government’s own data shows that the UK is set to breach the EU National Emissions Ceiling Directive for both ammonia and PM2.5.
The government’s solution to this dilemma is to leave the EU and create its own green watchdog, the Office for Environmental Protection, which will doubtless prove as toothless as the Environment Agency, and other similar government-funded organisations.

The problem that needs to be solved by car manufacturers is not so much the 1,800 deaths that occur on our roads each year, but the 64,000 premature deaths that occur annually from air pollution (“Driving may never be the same again. But what a ride it’s been!”, Focus).
This has been given renewed urgency by the realisation that Covid-19 mortality is closely linked to levels of air pollution. Thus city dwellers are between 40% and 80% more likely to die from Covid-19 than their rural counterparts, an observation that would go a long way to explain the higher mortality among members of the BAME community.
