The Paris agreement was a sop in Paris even as it was taking place. James Hansen said so, so did I, if that's of any significance . The Paris agreement was stillborn. . We are at 1.5 deg already, the idea being put out that you have to wait 20 years to prove this is delusional. And the northern hemisphere is warming at twice that rate.

The world is heading for 2+ deg rise by 2050, (it's presently a quarter of a degree/decade) and probably 4+ deg by 2100 as the planets warming is obviously accelerating as it's losing its capacity to absorb the CO2 and methane and the oceans' surfaces the heat.

We need to reduced CO 2 emissions by 9% per annum, says Guterres. Covid reduced CO2 emissions by 5.4% now rebounded to highest ever. So we need a permanent state of recurrent pandemics killing perhaps 60 million people every year and restricting movement and economic activity, to get our 9% reduction.

If ordinary folk like you and me are still driving an ICE car (I don't), or taking diesel buses or trains, heating your home with gas, or pretty well buying or using anything with a fossil fuel energy input, or worse still, flying, then we are the problem.

But nothing will happen. The Amazon will turn to dust, the ice caps will melt and in the lifetime of our children, the world will become a hostile place where survival is a matter of chance and not choice.

How long do the tires last on your Nissan Leaf? Just curious.

Microparticles from road tyres are “high concern” pollutants, research shows

Plastic microparticles released into the environment from common road tyres should be treated as a “high concern” pollutant, that may exceed chronic safety limits in some heavily contaminated environments, new research has shown.

A team of researchers, including experts from the University of Plymouth and the University of Exeter, looked at the chronic toxicity of particles and chemical leachates found on a series of popular tyre brands.

They then looked at the effect these particles and chemicals would have on small planktonic crustaceans, the water flea (Daphnia magna).

They discovered that the plastic pollutants from the tyres showed a distinct effect on both the reproduction and development of the water flea – which also displayed visible particle uptake within the.ir digestive tract.

When looking at the leachates – liquid that has passed through the tyre material, taking some of the harmful chemicals with it – they found a strong presence of zinc, titanium and strontium as well as many organic chemicals.

Overall, of the numerous organic chemicals present during the test, more than 50 were found across all five tyre brands, with a significant number of those chemicals classified as very toxic.

This new research shows that tyre particles are hazardous pollutants, and should be treated as a particular concern close, to or possibly above, chronic environmental safety limits in some locations, researchers say.

The research, published in the Journal of Hazardous Materials, is part of the
TYRE-LOSS: Lost at Sea – where are all the tyre particles? project being led by the University of Plymouth with funding from the Natural Environment Research Council.

Where the rubber meets the road: Emerging environmental impacts of tire wear particles and their chemical cocktails

Abstract

About 3 billion new tires are produced each year and about 800 million tires become waste annually. Global dependence upon tires produced from natural rubber and petroleum-based compounds represents a persistent and complex environmental problem with only partial and often-times, ineffective solutions. Tire emissions may be in the form of whole tires, tire particles, and chemical compounds, each of which is transported through various atmospheric, terrestrial, and aquatic routes in the natural and built environments. Production and use of tires generates multiple heavy metals, plastics, PAH's, and other compounds that can be toxic alone or as chemical cocktails. Used tires require storage space, are energy intensive to recycle, and generally have few post-wear uses that are not also potential sources of pollutants (e.g., crumb rubber, pavements, burning). Tire particles emitted during use are a major component of microplastics in urban runoff and a source of unique and highly potent toxic substances. Thus, tires represent a ubiquitous and complex pollutant that requires a comprehensive examination to develop effective management and remediation. We approach the issue of tire pollution holistically by examining the life cycle of tires across production, emissions, recycling, and disposal. In this paper, we synthesize recent research and data about the environmental and human health risks associated with the production, use, and disposal of tires and discuss gaps in our knowledge about fate and transport, as well as the toxicology of tire particles and chemical leachates. We examine potential management and remediation approaches for addressing exposure risks across the life cycle of tires. We consider tires as pollutants across three levels: tires in their whole state, as particulates, and as a mixture of chemical cocktails. Finally, we discuss information gaps in our understanding of tires as a pollutant and outline key questions to improve our knowledge and ability to manage and remediate tire pollution.

Re: Your Leaf.. re tyres, a bit of a red herring, methinks.

I know exactly - 50,000 kms or six years. I've just changed them. Tyres are polluting, ok, but irrelevant for the most part in dealing with global warming - though a tonne of tyres is responsible for around 700kg CO2 emission. There are about 30 kg of tyres on a medium car. So one tonne represents about 30 changes of tyres or 1.5 million miles, A petrol car will produce around around 4.6 tonnes CO2 per year, say 12,000 miles. So 1.5 million miles will produce 500 tonnes of CO2 or more, conservatively. Makes the tyre CO2 rather pale in comparison. And the petrol and diesel emissions are likely just as detrimental to health. So don't go on about tyres please - a red herring.

Re: Have you driven a petrol car or perhaps been in an aircraft recently?.......

HI folks, I'm not getting at any of you specifically. I drive a Leaf. Yes, there are tyre particles, a health hazard but no CO2 emissions (well a small amount as NZ power is about 87% renewables) and I've flown UK/NZ. I said "we". But don't go on about them, it's not relevant to global warming. And driving a Leaf with a renewable power supply is actually "better than" driving an ICEV, but worse than walking or cycling or public transport, if available. I agree.

I was merely putting Guterre's report in context, I thought. Merely pointing out the impossible job humanity has set itself. Monbiot's deal with the devil. A debt to be painfully repaid.

We all live a life style that pollutes - plastic, tyres, fossil fuels, concrete, asphalt, chemicals, non-stick pans, bricks, doesn't matter, .

Just pointing out we all have and do these things, and we won't do without them, even environmentally concerned folk like me, we are all involved. It's not hypocrisy, that's something different, a lie to yourself and others. But it is a failure to live up to what you know what you should do. I'm not lying to myself, merely being an inadequate human being to my own precepts. .

**Exclusive: Lifeboat News calls for the 'killing' of 60m people per year and destroying the economy to 'reduce CO2 emissions'**

(Not disagreeing that the stated reduction of emissions needs to happen if the worst effects of climate change are to be avoided, just that you may want to be a little more careful with your wording! There are thousands of people out there just waiting to pounce on evidence that the elites are pushing an agenda of depopulation and economic sabotage so that 'you will own nothing and be free', using climate change as an excuse now that covid is no longer serving the purpose. Language like the above will merely confirm their suspicions and make it even less likely that they will support measures to transition away from fossil fuels. Just sayin'... Oh, and taking personal responsibility for systemic problems is a recipe for frustration & failure IMHO. I)

That levity aside, I am not at all well read on this topic (so thanks to the people in this thread, and others, who post stuff on it here as that's my main source) but I think we are screwed. When the people who have the ability to change things at the scale needed are in the pocket of the people who have most to make from NOT changing anything we are just going to ride over the cliff and then all best are off.

On the bright side, I might be dead by the time it kicks off

...no amount of cajolery, and no attempts at ethical or social seduction, can eradicate from my heart a deep burning hatred for the Tory Party...So far as I am concerned they are lower than vermin.

Yes, the post-ironic age, I'd forgotten that.
