NoelEvans here's an interesting little website explaining where it is assumed oxygen comes from. They make an interesting point about deforestation:

[COLOR=left=#000000]Deforestation is another popular concern. Although the destruction of large areas of rainforest has many other serious environmental effects, it is considered unlikely to significantly reduce [/COLOR][COLOR=left=#000000]oxygen[/COLOR][COLOR=left=#000000] levels. In addition to trees and other green plants, rainforests support a whole range of [/COLOR][COLOR=left=#000000]oxygen[/COLOR][COLOR=left=#000000]-breathing life. It seems that these forests contribute very little to atmospheric [/COLOR][COLOR=left=#000000]oxygen[/COLOR][COLOR=left=#000000] levels overall, as they consume almost as much [/COLOR][COLOR=left=#000000]oxygen[/COLOR][COLOR=left=#000000] as they produce.[/COLOR]

As the Scientific American points out nobody really knows!

I've tried to get rid of all the random symbols in the quote above but have failed miserably!

Fixed it for you.

Lazy. Or perhaps you find it too complicated? Separating metal, glass, plastic, paper/cardboard and food waste - blimey, you need a science degree to work all that out! No, best sling it all into landfill and use up more electricity and diesel to extract and refine fresh raw materials

Buster15, have a look here: Climate Change - The Facts and here for Part 2 . Mr Attenborough is simply wrong in a lot of what he says and that's using IPCC and other reputable sources to show what the actual facts are.

Regarding the fabled (and mythical) 97% have a look here , here or here to see how the visually arresting figure of "97.1%" was cunningly arrived at.....

Watching the peaceful Climate Protests in London and thinking it is only a matter of time before the Agents Provocateur are sent in to stir up violence and turn things ugly !

No doubt about that, useless idiot of yesterday just about sums it up to an oil drill T head. In one sense that is. In another way of looking at the same dimorphous scenario, a lifetime of profligacy in energy resources saving has enabled one to construct quite a sensible little portfolio of consumer related items, from tobacco and munitions of war to energy products and indeed, even waste recycling. Such careful investment over the long term, aided by a lifelong addiction to never turning off a light switch, has ensured that the personally related useless idiots of today will have, as their natural inheritance, oodles of politically incorrect investment holdings from which socialistically abhorrent vantage point they can continue the family tradition of wasting a penny to make one, a maxim of life that works well as long as one always wastes slightly less than one makes and in order to make that work perfectly of course, one must make sure that public profligacy continues unabated.

It is important that we have the opportunity to review the information with an open mind.
Couple of points.
There is a difference between climate change and weather. We can all pick out specific years that buck the trend.
However, the data is very clear. Since the industrial revolution the trend of temperature rise is clearly increasing. No one said it had to be a straight line increase.

If the global temperature was not rising why are the ice caps melting. Physics is physics.
Ice only melts when the water and air temperature rises.

Burning fossil fuels made of carbon releases carbon dioxide. That is a fact is it not
CO2 is a greenhouse gas. That is a fact is it not.
The amount of CO2 in the atmosphere has doubled since widescale burning of fossil fuels. That is a fact is it not.

Isn’t the problem that this planet has too many human beings who all want everything that every other human being has?

We will never fix it.

Buster15, to answer your points in order:

1. I am quite aware of the difference between "climate" and "weather" thank you.
2. Individual years were not singled out, trends were as the author was referring to "climate" rather than "weather"
3. The data is indeed very clear, temperatures have been increasing since the Maunder minimum / Little Ice Age in the late 19th, early 20th Century, before CO2 levels increased significantly.
4. Physics is indeed physics and nobody has yet PROVEN a direct link between CO2 production and increased temperature. There is however a direct link to increased growth in an environment with increased CO2.
5. CO2 indeed a greenhouse gas. If it wasn't we would all have died eons ago.
6. CO2 has increased from around 180ppm to the current 410pp when it is below 240ppm ice sheets cover most of the Northern hemisphere. This increase has resulted in a temperature increase of approximately 0.5C

The seas haven't flooded the coasts etc. Move on.

A point of view that is probably not going to be too popular on here. I think the days of cheap flights are drawing to a close. There is little doubt that because high flying jets put the pollution into exactly the wrong place we will see ticket prices rise dramatically over the next few decades. It does seem crazy to me that people go to New York for the weekend. I don't really have a dog in this fight having only one son who at thirty shows no inclination to reproduce, just sayin'

Buster, I notice you didn't address a single item in my post, just told me to go watch TV (not to mention the show you referenced was not broadcast on this side of the pond).
Intelligent debate requires effort - not references to some random TV show.

All very interesting. The most often quoted temperature rise is 0.8C but it is dependent on the start point.
As you accept the temperature is rising and not staying the same and not dropping.
Most important this is a global average. Consequently some areas will be higher others lower.

I am sure that you have seen the graph with CO2 increase and temperature.
They align very well.

Anyway my friend, you have your own views and I respect that as at least you have taken the time to understand the science.
Not sure how old you are but if you are a youngster you will get the opportunity to find out.
I am in my late 60's but do have very young grandchildren and that is why I am passionate about the subject.

These demonstrators are protesting about man-made "climate change".

Much of the damage has been done as world population has increased. If the demonstrators are really concerned, shouldn't they forego having children for the greater good, rather than telling other people how to live their lives?

I see Emma Thompson is now saying that "if she could fly cleanly, she would".
How about this for a radical idea Ms Thompson; stay this side of the pond and make your movies in one of the many studios over here!

I had no idea where you live.
Nevertheless, I am not a climate change specialist so I rely on the experts.
I would be ecstatic if climate change was as Donald Trump says just a hoax.
But in my opinion he is lying when he says that so with respect to him I prefer to listen to actual data and the science behind that data.

It is an inescapable fact that global temperatures are rising.
It is an inescapable fact that CO2 levels are rising.
It is an inescapable fact that we are damaging our planet.
It is an inescapable fact that the ice caps are melting and that sea levels are rising.
These are the fundamentals.
I will look back at your post and read your points again.

it is an inescapable fact that the climate cycles through extremes of temperature.
It is an inescapable fact that, despite his courtiers encouragement, Canute could not hold back the tide.

No they won't, the Americans will never let it happen. Cheap flights are are here until the end of the world. I have four sons ( I settled on two, my wife didn't) and none of them show any inclination to reproduce either.

I was going to make almost exactly the same post! When she was interviewed, she was trying to justify the fact that “I have to fly because of my career and so it’s only several times a year.” Most of us poor peasants usually only get to fly once a year for our main holiday - If we’re privileged enough to afford one!

“Speaking to reporters from the Extinction Rebellion campaign group's pink boat, she said did not fly as much as she used to - and planted a lot of trees.”

I’ve planted a lot of shrubs in my garden - does that count?
