I find this terrifying.

There is only one way to reduce emissions, that is to reduce global population, for two reasons.

Population is going to continue to grow for 50yrs

The lifestyle expectations of the increased population is going to increase. They will increase the demand for manufactured goods.

There is no chance whatever of reducing emissions, that does no mean that we should not economize where we can.
We will fail.

Is anthropogenic? My grammar's all over the place, sorry!

Alegrias1 Sat 07-Aug-21 10:41:04

I meant mitigations for the change in climate Esspee, and I just wondered, this being a discussion forum and all. Its just that you seem intent on letting us know that its not the UK's fault and anything we do will be negligible because China/US/whatever are polluting much more than we are. And I still haven't forgotten that you are not entirely convinced its not anthropogenic wink

Seems a sensible position to take Esspee*

Esspee Sat 07-Aug-21 10:06:17

Not sure what you want me to give solutions for Alegrias1 CO2 production? the gulf stream possible reversal? overconsumption of resources? or the overdue polar reversal which will have very severe repercussions in the short term.
I shall leave the solutions to better minds than mine while doing what I can to minimise my personal impact and reminding politicians that they have a duty to make this world a better place.

Esspee, sorry, not "Esspee"!

Alegrias1 Sat 07-Aug-21 08:46:58

So what solution do you suggest "Esspee"?

Animal agriculture is by far the biggest contributor to planet destruction and no one seems to mention that because it will mean changing personal habits which no one wants to do. They just want to bury their heads in the sand and pretend it isn’t happening. Recycling a few yoghurt pots isn’t “doing all we can”.

It is a big contributor, but not the biggest.

And I don’t think you are right about no one talks about it.

It is always mentioned in any discussion of emission.

CO2 emissions by country are even more interesting

Katie59 Fri 06-Aug-21 18:15:46

I’m surprised that Canada and Australia are high on the list no surprises for the rest except China which has a massive population and massive manufacturing energy use.

Esspee Fri 06-Aug-21 16:51:18

Apologies Katie59. I was trying to do too many things at the same time and assumed you were referring to our contribution to CO2 emissions as this thread was on the subject of global warming contributing to possible reversal of the Gulf Stream.

As can be seen on the attached graph the U.K. is not nearly as bad as many countries which have no intention in reducing their reliance on fossil fuels.

Whitewavemark2 Fri 06-Aug-21 15:01:57

Oh I’m not so daft, although it doesn’t seem to have much support?

Alegrias1 Fri 06-Aug-21 14:56:09

Just in time there WWM2 ???

Look up Prof Lovelock and Gaia.

Whitewavemark2 Fri 06-Aug-21 14:54:16

Before the scientists have a melt down, I realise that my post is not based on fact?

Alegrias1 Fri 06-Aug-21 14:52:53

That to Esspee

Alegrias1 Fri 06-Aug-21 14:52:16

Katie59 was talking about consumption of resources per head, your graph is CO2 emissions

Katie59 is correct.

As a species, we may be doomed. We probably won’t survive the planet but the planet will definitely survive us. ?

I do have some sympathy with your sentiments granmarder

I think that Homo sapiens is a pariah species, and perhaps the world is fighting back on behalf of all the species we have destroyed, the climate we are destroying, and the environment we are trashing.

Esspee Fri 06-Aug-21 14:44:43

Katie59

Our consumption of resources per head of population is amongst the highest, possibly the US is higher, China is way down. We have exported much of our manufacturing but we still consume far more than most.

You are incorrect.

I believe it, but I’m another who can’t get too worried over something I can do so very little about. Not that that will stop me doing what I can, but it’s such a minute drop in the global ocean.
Exactly this. As individuals we have very little power or influence. I haven't even heard heard much about Greta Thunberg recently, and she has tried her best to be influential.

I am not a global warming denier. A science based education teaches you to keep an open mind.
While Alok Sharma our climate minister <never heard of him oops> was jetting about to 30 countries in the last seven months (it had to be face to face meetings of course) China was building a new coal fired power station every week to add to their total of something like 1,058.
Meanwhile the U.K., with an abundance of coal, has closed down ALL our coal fired power stations to protect the environment and is buying in wood pellets from Louisiana where the trees are cut down, dried and turned into pellets using American power then transported to the U.K. by ships burning polluting heavy fuel oil, then from the port of entry it is shipped to the Drax power station in Yorkshire which, incidentally, sits upon a huge coalfield.
Germany burns the most polluting coal of all - lignite. Australia and America are also major polluters.
Nothing this country does will make more than a very tiny difference to world pollution.

My science based education means that I can keep an open mind about things without my brain falling out.

But your science based education means you question whether there is enough evidence to say climate change is anthropogenic.

Okey dokey.

What this country can do is use its power, both hard and soft, to influence the major polluters in this world to move in the right direction. We can lead by example. Our power has been affected by the Brexit debacle but the world does look to our scientists and technologists for leadership. This is a chance for us to show if we really are Global Britain, or we just want to hide in our corner of North West Europe shouting "its not our fault" at people.

Why does that happen!!
