    Also some South African plants and North American plants what has changed is the intensity and frequency of the fires. In some parts of the world fire control measures have allowed the build up of more flammable material on the ground so the fires have more to burn and are more intense. Changes in rainfall mean that the ground is drier, the undergrowth is drier, the trees are drier so they burn more thoroughly.
    I grew up in Lincolnshire and in that part of the country the Fens were drained in the 18th century and the water levels have to be actively managed even today. This was not related to changes in sea level or climate change but more to do with the desire to make more money out of the land. At one time there was extensive areas of marsh around the Humber Estuary reaching as far as York, similar areas were found around many UK Estuaries.

      This predates Greta by a couple of decades at least and yes it is a thing. The Anthropocene mass extinction (6th mass extinction) is largely concerned with our effects on the other species that share this planet with us. Humans have driven many species into oblivion, by over hunting/fishing, by causing habitat loss, by spreading disease from place to place. Many species have become extinct without our even knowing they existed.
      Climate change is yet another factor adding to this extinction.

        From the point of gardening. Yes we learn of the many ways that plant propagation takes place is vast. Yes, Gorse seeds have to pass through fire. Other seeds need to be ingestested by animals and birds and later pooped out.
        Just a thought. Might there be a super human being, power behind all this?

              If you want to see how weird and wonderful plants really are, then have a read of Plant and Planet by Anthony Huxley published in 1974. This is a well written and readable account of plants in all their different aspects. Light on pictures by modern standards, just some sketches. I read it when it first came out (Public Libraries were wonderful) and it is one of the things that got me seriously interested in plants.

                In regards to fact 1: Various scientists have stated that as todays climate is getting warmer, its causing the polar ice caps to melt, and sea levels to rise. These facts seem to be generally accepted. As some people will be aware, there was what is often referred to as a mini ice age that started around the early 1400's. It logical that before an ice age starts, average temperatures must be higher. Therefore, the logical conclusion is that pre-mini ice age average temperatures were higher. Therefore, the ice caps would have been smaller. Accept todays thoughts in regards to this, and the older ones must be accepted. Either both are correct, or both are wrong.

                Fact 2: Sorry, no links. Living in one of the countries that was a big part of the Viking country, all we need to do is go to museums, talk to archaeologists that have carried out the excavations. Danish ones in the case of Greenland.

                    The fact is both of your stated facts are incorrect, and easy to disprove.

                    Some facts, but only for the UK.:smile:

                    2019 record temperatures conclude a decade of records - Met Office

                    Not totally sure how it all adds up, the records only seem to go back to 1910 or thereabouts.

                    Are they trying to make more of it? I dont know, I only go on my personal feelings and to me I've not noticed any real warming, I still think we have the worst of winter this year to come.
                    To me the springs are getting colder and drier, I have noticed that.

                    My rainfall this year has come out at 703mm which is very similar to last year, over 300mm of that came in the last three months of the year.

                      I think the thing is Pete, that it’s easy to look at things locally. Weather/climate is very complex, which means we might see contradictory events. It’s the overall global temperature rise that we should be focusing on, imo. I know you don’t have much time for ‘experts’, but shouldn’t we take notice when most of them are singing from the same hymn sheet? Who do we turn to when we’re ill? The doctor (expert). You made an earlier reference to the ozone layer. It was the experts that identified the problem, and it was the experts that sorted it by identifying the cause, CFC’s. As far as I’m aware, the ozone layer is recovering. It’s good to be sceptical, but as far as I’m concerned, this is something ‘we’ can’t take chances with.

                        You stated (fact 1) “Around the year 100 AD, water levels were higher than they are today”

                        Quote from Past sea level - Wikipedia “The last time the sea level was higher than today was during the Eemian, about 130,000 years ago.”

                        You stated (fact 3) “1000 years ago, Greenland was green”

                        Quote from Greenland ice sheet - Wikipedia “The Greenland ice sheet (Danish: Grønlands indlandsis, Greenlandic: Sermersuaq) is a vast body of ice covering 1,710,000 square kilometres (660,000 sq mi), roughly 80% of the surface of Greenland.”
                        And “The oldest known ice in the current ice sheet is as old as 1,000,000 years old.”

                        Worryingly, “If the entire 2,850,000 cubic kilometres (684,000 cu mi) of ice were to melt, it would lead to a global sea level rise of 7.2 m (24 ft)

                        Yep, experts, I do have time for experts, but as far as I'm, concerned they are a bit late coming up with all this, bearing in mind we dont have much time left, and who are they?

                        No, we get Greta fronting it, in a very aggressive way, blaming all of us that have been around for a few years.

                        I'd just like to point out that when I was a kid we recycled bottles, used newspaper for fish and chips, rarely used much in the way of plastic.... paper carrier bags etc.
                        I could go on but I wont.:smile:

                        Its mostly her generation that throws plastic coke bottles into my garden half full, its her generation that requires taking to school by 4x4 because its far too dangerous for them to be out on their own, its her generation that cant live without a mobile phone, I could go on, but I wont.:smile:

                        I was actually thinking many years ago about the loss of wildlife and habitat on the planet, climate change is just one of the results of over population by human beings, but who is pointing that one out.

                        Greta is not an expert, a respected expert fronting all this, would IMO, be a much better idea.

                          Climate is definitely changing, of that there can be no doubt, and equally there can be no doubt that a lot of human behaviours need to be looked at, as we are clearly not taking care of our environment as much as we could or should.

                          However, the climate of the planet has always changed and will always continue to change. Yes, some of the experts/scientists have theories that back up the current stance that CO2 is the driver, but there are also a large number of experts/scientists that disagree with that entirely - the problem is that the latter group of experts are being de-platformed; surely the whole idea behind science is that it is built up using data interpreted in various ways?
