It does kind of put piffling issues like Brexit into perspective.

I wonder what they'll say in 13yrs time?

Oh shit?

I can remember when they were griping about Acid rain. They said that in 10 years time, the forest areas in New York State would halve. They spent 10 years producing a report that found that not only it didn't happen, but that most acid rain came from natural sources.

The problem is not really the scientists per se but rather the media who pick up a snippet and blow it all out of proportion.

Let's face it in the past just look at all the bad things for health alone that have been subsequently debunked, the biggest being the MMR vacine.

The media has a lot to answer for.

It is mostly the media that take one study, even a dodgy one, and treat it as gospel. So one study from one place says item 'x' is bad and everyone loses their mind. Some things like red and processed meats, do eventually get enough evidence to show they're bad but that's why something like the NHS or the World Health Organisation are better sources for that info.

Global warming though doesn't really have any serious scientific detractors.

Windy lately, isn't it ? And the snow thread has been quiet ....

When the weather is excessively hot or cold, it is because the heat or coldness has come from somewhere else. That "somewhere else" will be cooler or warmer as a result. It is just moving around. Eg When there is a heatwave originating from the Sahara, what is the temperature in the Sahara as a result?


I can remember in the early 80s, there was a lot of talk about another ice age coming.


Evidence has been found that in the relatively recent past, they were growing grape vines to make wine in Norway. Nowadays with selective breeding of vines, we can grow grape vines in Southern England, but not much further north. Things must have cooled down since that time in Norway.

Climate, not weather...

And in the past, the climate in Norway was conducive to growing grape vines. It takes 7 years to get them to the point of producing grapes. In the past Greenland had a climate where there was little snow or ice, hence the "Green" in Greenland.


The snow and ice in the Arctic and Anarctic has created from water sucked out of the atmosphere. Could that carry on indefinitely without any effect?

Sort of I guess. Heat is slowly moving around the world but I don't think the temperatures 'drop' so much as they just don't increase but the atmosphere is constantly moving heat out of the Sahara and around.

But temperatures globally are increasing and one of the problem with climate change is the mechanisms which allow these transfers of heat and cold can break down.

Show me an era where and when the climate hasn’t changed.

Most climate change in history took a very long time, geological ages and millions of years, not big increases within the lifespan of a single human being. The few times there were sudden changes due to some sort of geological event, i.e loads of volcanos going off, it saw lots of life of earth dying. This time there is no geological event other than human activity.

Since the dawn of civilisation we have had climate change from warm to the ice age and so on and so on.

Yes, but it took tens of thousands of years, not hundreds...
