It’s so good to see some climate scientists at last starting to speak up about the awful over the top things Extinction Rebellion activists are saying, though I wish more would speak up and speak up more strongly.
Here is a meme that may help with sharing:

Yes XR activists, climate change is a serious issue BUT “Please STOP telling kids they may not grow up”
IPCC author Dr Tamsin Edwards

This is not a high quality paper, it's riddled with errors. It should never have been on mainstream news or on TV. Those 11,000 scientists are not authors - they are just signatories and one of them is the illustrious professor Micky Mouse of the Micky Mouse Institute of the Blind in Namibia. Of course they removed those names once they were discovered, but this shows how easy it was to add signatures to it.
Climate change is a serious issue but it does no good to promote things like this as if they were on a par with the IPCC reports.
The only section number cite to the IPCC is mistaken, says that it says we need carbon taxes much higher than $15.25 - the actual figure in that section for an example carbon tax together with other measures is $7.

This is running with click bait titles suggesting massively more people are at risk of sea level flooding than before. But it’s just better elevation maps. The sea level rise is the same but more people than they thought are already living below sea level protected by dikes, as for Holland.
It makes no difference at all if the elevation data is already good. Example story to debunk:

Rising Seas Will Erase More Cities by 2050, New Research Shows

This is mainly due to an increase in their estimate of the number of people currently below sea level (many people already live below sea level not just Netherlands). They estimate that

This is the first day that countries can give their one year notification to leave the Paris agreement. It's no surprise that the US has given notification. But he is not speaking for the city of Pittsburgh, who have taken strong action on climate change for over a decade, and many others in the US are in support of the agreement. Withdrawal is largely symbolic, and won't change anything, as there is no longer central federal support for climate action in the US as is.

Here I debunk an article in the Financial Times - although by the title it is supposedly about myths about green technology and renewables, it actually perfectly highlights most of the scientific and even financial myths about renewables propagated by some economists who claim that green growth is impossible.

Rupert Read is a philosophy professor. Don’t watch his video if you are like the children and adults I help who get terrified of climate change.
Yes we do need to act on climate change. But we need to be informed by science. He is surely well grounded in philosophy. However, what he says in the video about climate science is mistaken.

We often get scary stories saying that Arctic methane emissions are increasing. Recently many are panicking about a story in NewsWeek which has been widely retweeted. When you drill down to the details is about a tiny patch of Arctic methane bubbles in the sea, four or five square meters in area.

Sea "boiling" with methane discovered in Siberia: "No one has ever recorded anything like this before"

This is the original Russian text, as auto translated:

This is another scary headline that doesn’t mean what it seems to mean from the titles. We do not risk a world without the conker tree and there is no way it can go extinct. After all it is easy to cultivate. Here is an example story to debunk:
'Alarming' extinction threat to Europe's trees (BBC)
They say

Ravaged by moths and disease, the horse chestnut is now classified as vulnerable to extinction.
The tree is among more than 400 native European tree species assessed for their risk of extinction by the International Union for the Conservation of Nature (IUCN).
About half face disappearing from the natural landscape.

As young children worldwide protest over climate change, I thought I'd do a post about Bernie Sanders' Green Climate Change plan.

(click to watch on Youtube)

Bernie Sanders' idea is one of many ideas but one of the ones that promises the most radical action most quickly. He plans to spend $16 trillion on it, and claims that all of this will be recovered, that it will pay for itself.

This is another study that has hit the news, this time scaring people with the idea that the whole of the US may lose all its birds rapidly in the near future.
Short summary - studies like this are hard to do and the 3 billion figure should be treated cautiously - there can be observer effects. If accurate, the reductions are mainly in the most common birds, and some of them nuisance species such as the starlings. There is no possibility of the most common birds in the US going extinct.

This is a story that is scaring some people. New research that is suggesting that perhaps the climate is more sensitive to CO2 than previously thought - but this is way jumping the gun. We get many results like this sometimes running too hot, sometimes too cold. Only the ones that go too hot hit the headlines. But the IPCC will look at all the evidence with their next high level review in 2021. Meanwhile we should use the values for the high level review in 2018 which remains our best estimate to date.

It's only 0.11% of UK greenhouse gas emissions and there are replacements already in use industrially as we ramp down to zero emissions by 2050.
This is a known problem, the technology to solve it has been in development since 2016 and in commercial use since 2016. Although it's only a fraction of a percent of emissions, it is important for the future as we ramp down to zero emissions. There is nothing here to be scared of, and we can still use renewables. This is another click bait article by the BBC that’s being shared widely on twitter today. Dozens of shares.
