As there have been a few few climate related posts in other sections I thought I'd start a thread that can allow discussion without hijacking a thread about Tdi300 exhaust emissions
I used to work in the ludite car industry in a strategic capacity and have seen many presentations and been on courses with CISL and the IET, looked at the positive case for low carbon business models/economies and held a piece of 15,000 year old ice at the British Antarctic Survey. I am highly convinced that man-made climate change is real, we and our grandchildren all over the world are all in real trouble unless action is taken very soon. For starters see attached a couple of links that may allow folks to read up on things, if they want to: https://www-falcon.csx.cam.ac.uk/site/CISL/resources https://climate.nasa.gov/evidence/ https://www.ipcc.ch/sr15/about/ 2015 90 XS SW Bowler 1998 TD5 CSW |

I can't get my head around this warming thingie. Icebergs are melting and sea levels rising , they say. But I can remember an experiment, when at school, where we filled a beaker with ice and water, to a certain level, and the next day the ice had melted but the water level was the same. So if icebergs melt isn't it the same thing? Can someone explain, Greta where are you?

If ice on top of the sea melts it does not raise sea level as the sea was bearing the load and hence being raised by it already. It makes no difference if the water is in a frozen or liquid state. That’s what your experiment proved.
If the ice is on land and slips into the sea or melts and flows into the sea, then sea levels will rise. This is because the land was previously bearing the load so not impacting sea level but now the ice or water is in the sea it is impacting sea levels. http://www.antarcticglaciers.org/glaciers-...-changing/ However sea levels are not the only issue, huge volumes of fresh water joining salty sea water could impact things like the North Atlantic drift which currently ensures the UK and Western Europe does not have as bleak winters as say Canada. https://www.weatheronline.co.uk/reports/wx...Stream.htm Last edited by Ianh on 15th Jun 2021 12:32pm.

In addition to those points, as the temperature of the sea rises it also expands

My understanding is that the problem is not that the climate is changing (as said, it always is in a state of flux). The issue is the rate of change. It is changing too quickly for ecosystems to adapt.
My personal (rather depressing) view is that we probably are slowly wrecking the planet. The way governments, nations and economies are organised we have become beholden to growth in terms of population and industrial output. The planet is only so big. Humans are so selfish and competitive as a species that I can’t see any meaningful action to preserve our resources until it’s too late. Our only hope is Musk and Bezos getting a shift on so at least a few of us can escape the confines of this small rock to continue the human race amongst the stars where resources are practically infinite. 2007 110 TDCi Station Wagon XS |

Take some comfort in that case that the planet will be just fine for millions of years after the human race has annihilated itself. The future of the planet is really not an issue. The future of the human race is an entirely different matter, and on that score the prognosis is not so good.
I am not sure that continuing the human race elsewhere is a very good idea. The analogy of the tenant from hell who is evicted after trashing your house, and then repeats the process in someone else's comes to mind. |

It is undoubtedly true that heating and cooling of the planet has occurred for millions of years. The difference now is that it’s heating up at a much faster rate than previous cycles, and it started at a point co-incident with the industrial revolution and the widespread additional burning of fossil fuels. I blame the Victorians

One extinction-level impact (which is something about which we could do nothing) and the nuclear winter will cool it quickly enough.
There have been many mass extinctions in the past, there'll be many more to come. I reckon the human race's is not far off. |
