In the climate emergency, our aim should be to maximise both the reduction of emissions and the drawing down of carbon dioxide already in the atmosphere. There is no safe level of global heating: every increment kills.

Maximisation is implicit in the Paris agreement

No, it’s to optimise.

Set off all the H Bombs tomorrow after lunch and we’ll have no human caused emissions by March. That would be maximisation. There would also be a certain cost to this. Thus we don;t want to maximise, do we? We want to optimise.

This means growing wood to burn in power stations, then capturing and burying the carbon emissions. It is likely to cause more harm than good. Could the committee’s enthusiasm have anything to do with the fact that one of its members works for Drax, the energy company pioneering this disastrous technology? Throughout the report, business appears to come first; nature and climate last.

Which is why we shouldn’t use bureaucracy or markets to do the optimising. Just reset prices and let the market chew through it.

Pacific Ocean’s rising acidity causes Dungeness crabs’ shells to dissolve

Difficult to understand how the Pacific is making crabs dissolve off Kent but it’s in The Guardian so it must be true.

In Saint-Louis, the consequences of climate crisis are tangible: thousands of people uprooted; houses destroyed; hundreds of children attending classes in the evening instead of in the morning because their school has been swept into the ocean. The World Bank, which recently allotted €24m (£20m) to combat the effects of climate change in Saint-Louis, estimates that 10,000 people in the city are either already displaced or live within 20 metres of the waterline, the high-risk zone.

And this is just the beginning. According to a study commissioned by the Senegalese government, 80% of Saint-Louis territory will be at risk of flooding by 2080, and 150,000 people will have to relocate. Most of west Africa’s coastal cities, home to 105 million people, face a similar threat.

Except, well:

He is referring to an engineering mistake, which contributed to the deterioration of the Langue de Barbarie. In 2003, heavy rainfall caused the Senegal river to rise rapidly, putting Saint-Louis at risk of flooding. As a quick fix, local government dug a four-metre-wide breach, or canal, cutting through the Langue de Barbarie. The effect has been the opposite of the one intended. Although at first the river level dropped, the breach quickly started to expand. It is now 6km wide and has cut off part of the peninsula, turning it into an island – and flooding Doun Baba Dieye.

It’s not actually about climate change, is it? It’s about an engineered change in currents and water flow wiping out a sandbank.

I was a climate change denier:

Our ancestors managed fire country for millennia. We yearn to burn once more
Cultural fire will protect the canopy where the koalas live – regenerating the tree that they eat

When he says it it’s ancient cultural wisdom.

Presumably my real crime was cultural appropriation.

An ideological commitment to free markets – advocated by those at Davos every year for the summit’s 50-year history – has been a consistent block to progress on the climate crisis.

In the absence of free markets who will be the Gauleiter to tell us what we may do?

Climate change could see UK seas filled with hake, anchovies and herring, study by Defra predicts

The evil of climate change is what?

Teen girls took over the climate movement. What happens next?

Umm, dunno really. No one sensible pays any attention until they’ve become women, do they?

The world’s first fully electric commercial aircraft has taken its inaugural test flight, taking off from the Canadian city of Vancouver and flying for 15 minutes.

“This proves that commercial aviation in all-electric form can work,” said Roei Ganzarski, chief executive of Australian engineering firm magniX.

The problem being that it doesn’t scale up. Neither in size of plane nor distance:

Battery power is also a challenge. An aircraft like the one flown on Tuesday could fly only about 160km on lithium battery power, said Ganzarski. While that’s not far, it’s sufficient for the majority of short-haul flights run by Harbour Air.

Blue Planet, Extinction Rebellion and Greta Thunberg are all household names bringing information about serious environmental issues to the masses. They’ve helped green issues shoot up the agenda for this year’s general election, with a poll last month revealing that more than half of voters said that the climate emergency would influence how they cast their vote.

If it wasn’t for the media these scientific messages wouldn’t be heard or understood by millions of people. And Greta Thunberg’s extraordinary global impact demonstrates her mastery of skills that have little to do with what we usually think of as science.

None of the three are telling us the science.

Which is – we’ve already done sufficient to miss the more hair raising predictions of climate change. What’s left to do reveals a chronic problem that will be easy enough to deal with over the next few decades. That’s if we decide we’re going to believe the IPCC reports of course. If we decide we’re not going to then even less needs to be done.

There is no science anywhere which states that we need to cease economic growth and overthrow capitalism and free markets in order to deal with anything at all – other than varied teenage phantasms perhaps.

Climate models have accurately predicted global heating for the past 50 years, a study by climate scientists from the University of California, Berkeley, the Massachusetts Institute of Technology and NASA has found.

It’s building a model that tells us the future, not the past, which is the difficult thing.

Horses should be moved into bare paddocks, vets have said, because an abundance of grass caused by climate change is making them fat.

Gillies Moffat, director of a veterinary centre in Hythe, Hampshire, said the wetter and warmer climate has meant the animal’s staple food has grown more rapidly than in the past.

Apparently the worst that will happen is that the steaks will have a little more marbling in them…..

Sending just one less unnecessary email per day could reduce the UK’s carbon footprint by 16,000 tonnes per year, according to research.

That’s some 0.003% of the country’s emissions. Reporting the story might well have cost more than that.

Yes, this works:

The best thing St Greta can do on her cross Atlantic trip is to become a pirate.

This week’s Arctic blast will be so cold, forecasters expect it to break more than 200 records across US

But that’s just weather, isn’t it, not relevant…….

Brazil had hoped to secure more than $26 billion in fees from oil companies for the rights to exploit fields that the government said may hold 15 billion barrels of oil.

Instead, the country secured about $17 billion, with Petrobras, its own state-run oil company, and Chinese operators making the only bids.

President Bolsonaro wants Brazil to boost its oil production and to join the Opec cartel of leading crude producers.

However, international bidders were said to have been deterred by high fees, as well as the requirement to work with Petrobras, which had exercised rights to become the operator in two of the four blocks up for grabs. The other two licences secured no interest at all.

They’re asking too much rather than there being no interest at any price.

But all the Greens will now praise the oil companies, right?

A majority of the UK public and almost half of Conservative voters support a radical plan to transform the economy and tackle the climate crisis, a poll suggests.

YouGov found that 56% of people back the total decarbonisation of the UK economy by 2030 and just under half support public spending to make large swathes of public transport free to use.

Total decarbonisation in 11 years? They’re mad.

Jacinda Ardern’s landmark climate legislation has passed in New Zealand parliament, with historic cross-party support, committing the nation to reduce its carbon emissions to zero by 2050 and meet its commitments under the Paris climate accords.

But it’s not going to happen, is it? Not because someone’s passed a law at least…..

Petrol from algae. Bit of GM, we know that the chemistry is possible. Atmospheric CO2, seawater, few other bits and bobs, sunshine.

So we can make something akin to oil that way.

Obvs, price is a bit of a handicap. But now think that we get that down. To where we’re actually price competitive. $30 a barrel oil equivalent. Yes, OK, a what if but still.

So, what’s the cheapest way of beating climate change? Run those plants at double volume and pump the new algal oil back into the old fossil reservoirs. That’ll be fun, won’t it?

Labour has indicated it could ban the use of private jets within five years if it wins power, amid claims that billionaires should not be able to “trash the climate”.

Andy McDonald, the shadow transport secretary, has endorsed a report calling for a ban on private flights by 2025.

The report, compiled by the left-wing Common Wealth think tank, claims that private flights from UK airports contribute as much to climate change annually as 450,000 cars.

So, if one flies in can it fly out again?

Further, what’s the definition of a private jet? The Emir of Qatar has a private 747. Ownership? But near all are owned by companies. It’s more difficult than it seems….

Environmental activist Greta Thunberg is a long way from where she needs to be. Since a UN speech in New York in late September, the 16-year-old Swedish campaigner has spent weeks traveling overland en route to the COP25 climate summit in Santiago, Chile. But a last-minute change of location due to that city’s anti-government protests—the event will now be held in Madrid, Spain—has left her scrambling for an eco-friendly lift across the Atlantic.
