Indeed so. Will we be able to walk to continental Europe via Doggerland or will the Scottish raised beaches be actual beaches again ? In other words will our climate revert to where it has been.
PS I will have a walk up a 2000+ ft hill tomorrow the peak of which was once coral under the sea.
Whilst what you say it's true, and or may well be that we are just going through another period where is part of a natural change, what if it's not?
Before you answer that, I'll answer the obvious question which will be out back on me, what of it's not man-made climate change?
Then we'll have, hopefully, removed from the table the theory that the reason for the rises in temperature being linked to rising greenhouse gases.
If that's been achieved then we (as a human race) will be living with a lot less air pollution, are likely fitter (tell me there's not a link between children being driven less than 800m to school and obesity, yes there are other factors & is an over simplification), that we become less wasteful with all resources, we will likely see less wildlife being harmed by our actions and so on.
If after that it's then found that it's natural and nothing we could have done to stop it then that's fine and we'll have tried.
If however it is man-made (which may be that our 20 units added to nature's 90 units means that is more than the 100 units that the planet can cope with, and whilst we can't do anything about that 90, by limiting ours to 10 or less would limit the impact) and we do nothing then we've got no one but ourselves to blame.
Now whilst the UK's emissions are currently about the global average per person, it should be noted that there's several countries which bring that average up by quite a lot and so the global average is also too high to be content to stop at. Especially given that there's likely to be many who don't get down to carbon emissions comparable to where we currently are for quite some time. As such, and this maybe unfair but if it's what needs to happen to limit the impacts of climate change (which are far from fair as they tend to impact those who work the land more than those who live an urban lifestyle, which tends to mean it impacts the West very little and the rest of the world a lot) then it's a small price to pay.
The emissions from the UK could be reduced quite significantly if a fairly small number of people significantly changed the way they did things. For instance 70% of regional flights are made by 15% of the population, with over 25% of region flights being made between London and the Central Belt. Whilst about 1/2 of these are to make connections to international flights there's still 3 million flights which could (with limited delays when you compare city centre to city centre journey times, which what not everybody by a long way there's still quite a few for whom getting to a suitable station will still take quite a bit less time than getting to the airport) use rail instead.
Does that mean that I support people doing stops things to highlight our need to change, no. However do I understand that they are frustrated with people who are willing to put their head in the sand over climate change, to the extent that they aren't willing to consider that it could be an issue and we should at least try to ensure that it's certainly not or fault.
