See THIS for a report on the stress being put on deep water corals by the increase in atmospheric CO2. Over half the world's corals are cold and deep water species and they are suffering.

See THIS Guardian report on developments in the Arctic and Siberia....
One doesn't want to be alarmist but on any level of understanding, this perturbation in the fundamental mechanism governing air circulation in the Far North looks serious.
In case you hadn't picked it up the basic problem causing the spell of bad weather we are having at the moment is the disruption of the normal flow of the Jet Stream due to this polar warming, it has been forced South of the Isles leaving us open to the Siberian weather we are getting at the moment. Could this be a harbinger of things to come? Remember also the influence of Arctic temperatures on the flow of the Gulf Stream, the gigantic heat pump that keeps us warmer than anywhere else on the same latitude.
Climate change? What climate change.....?

I read that at the recent Conservative Political Action Conference in the USA - `an annual gathering of conservative activists from around the US that dates back to 1973' - many participants wore T-shirts with `I [heart symbol] CO2' on the front.

Worth keeping an eye on the jet stream. The cold spell is receding but the course of the jet stream is still hundreds of miles south of us in the Mediterranean when it would normally be north of Scotland. This is serious stuff......

Climate deniers like Trump will be running about telling everyone that this proves the climate isn't warming. The truth is that increased snowfall is exactly what you'd expect if Antarctica warms. The warmer air carries more water from the oceans and therefore it drops more snow.

I saw that report Tiz and had exactly the same reaction. The interaction of the wind and currents is complicated stuff and it's the broad picture over time that counts, not individual events.

See THIS BBC report on the news in the journal Nature that a study shows that the ocean currents in the Atlantic are at their weakest for over a thousand years. Exactly what climate watchers expected but no less serious for that. It all reinforces the perception that we have passed a tipping point and are now on a downwards trend. It takes centuries to build up an effect like this and centuries to reverse it. Not good news.

Climate change hasn't gone away.... See THIS for a warning from the environment agency that we are looking at water rationing in the future. I was thinking as I walked across the Green in Barlick this morning that if the present good weather continues we will be hearing warnings about low water stocks. Lo and behold I got back home and heard this on BBC4.

This is interesting but I have a couple of reservations about it. First, would we ever be able to install enough fans to make an impact on the rising CO2 levels? Second, if the harvested CO2 is used to make fuel it simply puts CO2 back into the atmosphere when the fuel is burnt.

Shades of my post in Science Matters. Isn't this the chemical equivalent of perpetual motion?
Meanwhile the world is far more interested in more important matters like Free Trade and Brexit..... The certain extinction of most of the human race is a sideline......

Climate change looks like being the cause of the sudden deaths of baobab trees in Africa, many of them thousands of years old.

"We suspect that the demise of monumental baobabs may be associated at least in part with significant modifications of climate conditions that affect southern Africa in particular," said the team, led by Dr Adrian Patrut of Babes-Bolyai University in Romania. "However, further research is necessary to support or refute this supposition." I was just trying to be a bit more concise. :extrawink:

Nice try - but I'm not convinced. :smile: I read somewhere that it is easier to get funding for any research if it can be linked to 'climate change'. Never heard of that university before or even the city where it resides, but it looks impressive. Babes Bolyai

Three of the paper's authors are Romanian but the other four are at research institutions in South Africa and USA. The journal `Nature Plants' is one of the `Nature' family of British journals. Nature journal itself is one of the most highly respected journals worldwide.

I think that comes close to being one of the logical fallacies they told us about at school.

Since you wrote that you'd never heard of the university or the city where it is situated I thought you would like to know at least that the journal is well-known and respected.

I'll bet there have never been so many posts on baobabs in OG before! :smile:

David, I am all for healthy scepticism but we have to trust someone and Nature have a fine reputation which I am sure they would not endanger so they must thrust the research. I shall do the same until better evidence proves it wrong. That's how science reporting works....

See THIS for a report by ITV on the wildfires in California. Started when a car had a mechanical problem causing a fire. Scientists have said that one of the causes is climate change as this is an exceptionally dry season and very high winds. It's so fierce that in some places it is generating its own weather.

Last year was the fifth warmest since records began. Not a big rise but significant as it adds to the pattern of the last few years. Nine of the ten warmest years recorded have happened since 2002.
Not sure if this is anything to do with climate change but see THIS Guardian report about the decline of King Penguins by 90% in their largest colony.

See THIS Guardian account of research that predicts that climate change is going to seriously affect China by 2070 making large parts of the Northern Plain uninhabitable by reason of drought.

For 20 years or more I've been trying to explain to people that the disappearance of the glaciers and mountain snow will result in more floods in winter and more drought in summer. They act like a `water battery', storing up the water as snow and ice during winter and releasing it gradually as the year progresses. Without the snow and ice forming all the winter rain will immediately rush down the great rivers and flood the plains, including many cities. In summer the rivers will run low or dry up and they won't be there to fill the reservoirs or power HE plants. Governments have been too short-sighted to do much to prevent it and they assume they can leave it to `the private sector'.
