Ed’s note: Solar dimming – the answer for global warming?

Smart Energy International

In January a group of scientists from across the globe published an open letter advising against dimming the Sun as a measure to lessening the impact of global warming and calling for an ‘International non-use agreement on solar engineering’.

Should the world ban solar geoengineering? 60 experts say yes.

But the eruption illustrated a question that has been dogging scientific and climate experts for decades: If the world got unbearably hot, should scientists and governments opt to put sulfur dioxide or similar chemicals into the atmosphere to slow the rate of global warming? The first report on global warming that was handed to a U.S.

Graphene-based packaging presented as first truly biodegradeable and compostable alternative to plastic

Envirotec Magazine

In addition, some bioplastics produce methane gas when they decompose, a compound with a global warming potential 25 times that of CO2. For example, in 2019, the BBC found that compostable plastics in Wales were going to landfills rather than being composted because almost all local councils were unable to deal with them.

Alternatively for farms that do not have the ability to produce LNG on site, Bennamann’s patented non-venting cryogenic storage tanks keep the methane as a liquid, from where it can be transported, similar to diesel, to wherever it is required.

Ice rink alternatives and their environmental impact

AGreenLiving

When the 1890s rolled around, the rush to patent ice rink surfaces began and has not abated since. HFCs heighten the greenhouse effect, while carbon dioxide similarly intensifies global warming. Carbon dioxide is a better alternative, though its use still contributes to global warming.

Who gets to decide whether we study solar geoengineering?

Grist

Although reflecting the sun to slow global warming has been discussed for over half a century , precious few experiments have actually taken place. In 2012, for instance, a British project to reflect the sun with water droplets was canceled due to conflict-of-interest concerns over patents.
