Global warming ... It's back and it's official ..

[pargyle]

Well at the risk of starting world war three on here ... and the thread being relegated to the cupboard under the stairs ...

It would appear that some very eminent American Scientists are now saying that the earth IS getting significantly warmer and that since the year 2000 there has been nearly a half a degree rise in the Earth's average temperature. That doesn't sound a lot does it ?

But then look at the graph in the attached article and consider that the horizontal axis with the time scale on it is NOT LINEAR ... Scary or what ?

So when are they going to be able to control the sun?

On Record, what about not on record, look at the bigger picture

I don't think there is any doubt the World is getting warmer.

The Medieval Warm Period wasn't warmer than today and many studies show that warming is now rising faster than almost anytime in history.

Here's a graph of multiple studies, you'll note this one references its sources.

I think they're too scared to give my dad the remote.

No references on that.

Nothing to do with the increase of hot headed people in the world then

very eminent American Scientists

Hmm Oxymoron?
Of course the world is changing. it's nature, we're probably helping speed it up a little, but we just have to live with it.
Of course the Tesco worshippers will all say the answer is even cheaper food and more foodmiles helped along by pumping chemicals into everything

Whilst I fully accept that there have been global changes in the earth's climate within the times of modern man, what struck me about this was the exponential rise in global temperature that we are facing in the very recent past. There is nothing that compares with this spike in any of the historical fluctuations and the predictions of what this rise will do to the earth's climate, as there is no model upon which to base them, vary wildly.

It's a complicated situation ...the melting icecaps are having an effect on the worlds oceans and the marked increase in temperature measured above the Polar ice caps are affecting the upper atmosphere balance. Ocean currents are not moving in the way they have historically moved and the jetstream (which has a major influence upon our climate) is becoming both weaker and much less predictable in its patterns of movement.

It is likely that we will see more extremes of weather in the short term but what the future will hold is very difficult to predict as we are already in totally uncharted territory - we certainly need the UN to make some strong efforts to curb the continual damage we are doing to our atmosphere as this situation is not going to improve until we make some serious efforts to reduce the amount of CO2 we are generating. The reduction in size of the worlds forested areas is contributing massively to the problem as these areas purged large amounts of CO2 out of the atmosphere, replacing it with oxygen - yet no body seems to be doing anything to retard this destruction.

The incidence of world natural catastrophic events in recent times appears to reflect the graph of climate change - so are we going to see more of those ?

Not slashing my wrists yet ... just a little concerned.

An even more eminent Russian Scientist said some time ago.

Well, some are - the 'size of Wales' project in Uganda sponsored by Welsh Government reached planting the millionth tree last February and has now been increased to a target of ten million (Swmbo helped them with one of their funding bids when she was out there) But when we've got the veggie types and the new fashion of lactose intolerance all demanding more soya and thousands of acres of rain forest being slashed down to supply this it's an uphill struggle.
Maybe we can do a three pronged attack here - reduce our carbon emissions, methane production and reduce the need for more arable land........... don't burn coal - torch a vegetarian instead.

Globalisation and lower energy usage don't really go hand in hand.

At some point the political class will work out it's a great excuse for protectionism.

Not enough fat on them ... takes 20 minutes less to cremate a fat person than a thin one apparently !! Obviously 20 more minutes of gas adds to the CO2 load in the atmosphere .... where's it all going to end ?

Rather ignorant about scientific research then.

There is certainly a link between the Sun's influence in relation to the earth's orbit around it and the shift in the earth's magnetic poles appears also to contribute to the long term fluctuations in the world climate.

But ... NOTHING, apart from man's influence on our planet, can possibly account for the current sudden changes (compared to geological time scales) in climate change.

Even the, so called, Little Ice Age of the middle ages (Between 1550 and 1850) is, in part, attributed to volcanic activity increasing world CO2 levels. But, in those days, the planet was not subjected to the additional influence brought about by the Industrial Revolution and subsequent exploitation of the planet. The world had the chance to recover from natural disasters .... it does not have that luxury now.

Yes and a fantastic job they are doing ... more countries should be taking note,

But ... at the same time estimates are that we are losing rain forests at the rate of nearly 30,000 sq miles per year - that's an area FOUR TIMES the size of Wales every year disappearing and not being replaced.

You are quite correct .. the deforestation of the planet is partly the result of the growing need for food ... but in the countries where it is occurring most it's food not for indigenous consumption but for export to developed countries that throw away more food than they consume. Big business rearing beef cattle and growing crops on a massive scale.....in countries where much of the population live on or below the breadline to feed fat Americans who need their Quad Burgers !! (Ok ... bit of exaggeration but a grain of truth in it ...).

These forests tend to be in the world's poorest regions and the concessions to harvest the timber resource have generated huge amounts of revenue that these poor countries have used to offset the debts they have in world banking terms and to provide cash for infrastructure development ... but it's a once only benefit and at what cost globally ?

There's something gross about this isn't there ?

Some of the figures in this talk might be an eye opener with regard to where a lot of green house gasses as released from, and potential solutions to reducing emissions.

That's an interesting lecture .... some food for thought. Would appear to work in a subsistence society but not sure that Big Business Agro-co would agree - from what I understand, in South America, the forests are cleared, the grass grows, the beef cattle move in, strip the grass and leave the land deplete of goodness and Big Agro Co moves in to the next site ...
