I think the major action occurs with the opening up of ocean basins? were we to wait a few odd lifetimes we'd see the African Rift valley opening into a new ocean and that would involve a little uptick in volcanic activity in the region as the crust collapsed into the earth and molten rock filled the fissure.... or something along those lines.
I think what these guys are looking for is an event like that which filled the Deccan traps with km's of lava back in the day???
I somehow think we'd notice a change on that scale....don't you?
Aye, a flood basalt eruption - now that, I concur, would certainly affect climate. But yes, I think we'd notice if that happened.And a shorter term change due to a supervolcano eruption would also, I think, also be noticed. Though I've not heard any reports from Yellowstone today .... :oOn that subject, Greenland ice cores suggest that the very coldest period of the last ice age occurred around the same time as te Toba eruption ~72ka, and was followed by a very rapid, massive, warming. I think evidence of an initial 'nuclear winter' followed by the effects of CO2 induced global warming (CO2 staying in the atmopshere longer than the initial dust and sulphur etc).

Nearly all UK wildlife looks cuddly in comparison to what you get in Aus...Our most dangerous creature is probably the mighty badger.
Our most dangerous creature is the deadly Highland midge! :DAnyway, the picture does look like a false widow, nothing like any of the many spiders I share my house with (many of which this time of year are a lot bigger and hairier!)Watch out though if it spins a web by the front door, you may not get any post .....

Well, lots of things come to mind, but first I thought it would be useful to deconstruct the 'sceptic' line. As there are several lines of attack, so there are variations and additions, but this as I understand it is the main line of reasoning:
1. Volcanoes are hot. Very hot.
2. There are volcanoes under the sea.
3. Heat transfers from hot to cold.
4. Therefore volcanoes are heating the sea.
Add to this the 'science is worthless' meme:
5. Volcanoes are heating the sea.
6. We (including scientists) don't know how many volcanoes there are under the sea.
7. Therefore nobody knows how much the sea is being heated by volcanoes.
Incorporate this into AGW:
8. Nobody knows how much volcanoes are heating the sea.
9. GWers are saying the sea is getting hotter.
10. We know that it isn't us.
11. Therefore It must be the volcanoes.
Did I miss anything?
A point I have made before with regards the "oceans warming due to more underwater volcanoes" argument is: how do we know that current underwater vulcanicity isn't unusually low?
Just because we keep finding new underwater volcanoes doesn't mean that 1,000, 10,000 or 100,000 years ago there was not much greater underwater activity.

I very rarely watch TV weather forecasts these days - not now I can see the models on which they're based myself .....

Which explains why I find them to warm as do a few other people. Downstairs is a nice 16.4C to 17C mission control at 18.6C with a nice breeze going through.
Room temperature used to be ~16
This is why you should put red wine (serve at room temperature) in the fridge before serving it - otherwise it's too warm .....

Central heating has turned us into a nation of wimps. We should all go back to living in castles

essan if you are going to quote my posts can you read the question properly
Sorry. I thought the question was why was there a week of colder then normal weather in S America this winter?To which the answer is: weather. With the added note of reference that much of the S Hemisphere has experience overall record warmth this winter. Which does not of course preclude spells of colder than normal weather as well.

Don't be so offensive, people can believe what they like and can you blame them for being skeptical when we are fed lies and deceit right left and centre from all the so called 'experts' in every field.
I would hardly call David Rose an expert! But yes,folk have the right to believe him if they like, just as they have the right to believe the Nigerian asking them to assist in the transfer of $20m ..... Personally though I would urge folk to stick to the actual science and not what the media tell them. And in that respect, even the BBC cannot be trusted. ALWAYS check the source. Not the media spin.

I've always found temps 19-20c in the house actually feels better when naturally occurring than they do if you choose to heat to that level. If it were 0c out and I heated to 19.5c it'd still feel chilly whereas it doesn't feel too bad at the moment.
I find 'natural' temps of 18-20c in the house as quite tolerable, whereas if it were -10c outside and the house was heated to 20c I'd find it much too warm and need to open the windows ......

Yes it appears there is a certain censoring of anything which could damage future funding.
Aye, like the warmest August on record at the South Pole?
And, indeed, warmest winter on record in Australia?
Meanwhile, the fact that, as nearly everyone expected, Arctic sea ice has not melted as much as last year (but still more than most previous years) is being trumpeted by some media buffoons as proof of gobal cooling!
-
anyway my question was to you how do you explain the bitter cold in south america then
Weather,Just because the world is getting colder and entering a catastrophic ice age, doesn't mean every part of the world wil be colder every year, nor that one part of the world might, for a week or so, see warmer than usual conditions. Does it?

I fear for the future - my missus feels the cold easily, and her mother's thermostat is permanently set at 30C. She walks around exhibiting occasional shivers at the height of a July heatwave, muttering that it's dropped cold, has someone been fiddling with the thermostat etc. If it's a hereditary thing, I'm screwed.
Sounds like she's Scottish. I hate going to Scotland in winter - every single (public) building (shops, pubs, hostels etc) is stifflingly hot, regardless of the outside temp. I'm sure Scots think that if exposed to temps below 25c in winter they'll drop dead ....

Given my thermostat is set at 15-16c there really wouldn't be much point in putting my heating on yet!As I rule, I wait until I feel cold whilst sat around wearing just a fleece top. So ~12c That normally only occurs after a run of air frosts. And then usually only for an hour or two in the morning before I get dressed .....

Where are they going to hide the Roswell craft no then!
Same place it's been for the past 3 decades - at the Kennedy Space Port.
On the far side of the Moon ......

I was getting up to 2 dozen starlings in my garden until I stopped putting out suet balls (which they were demolishing in a matter of minutes!) and making a right racket in the process as they squabbled over whose turn it was to feed. Still plenty of sparrows on the seed feeder - most adults seem to have raised 2 broods this year thanks to that feeder!

Actually, just to confuse things, although it starts off getting colder as you climb higher, it then gets warmer for a time ......and then gets colder once more before it then then warms up even more: such that the warmest part of the atmosphere is actually the thermosphere, over 100km up, where it gets much hotter than it does on the Earth's surface..... Only out into the exosphere does it then finally cool off again as you move out into space .....
For a good explanation , see:

9/10A bit dry, I suppose but after ave rainfall in May not a big issue.Lots of warm, dry & sunny weather, Not too hot.

Back in the 70's prior to the current alleged consensus of AGW climate scientist were adamant of an ice age being around the corner,
No they weren't.
Based on our understanding of ice ages at the time, it was thought that interglacials normally lasted only around 10,000 years and with the current one having started around 10,000 years ago it suggested the next one was imminent. Recent cooling (now known to be due to 'global dimming') supported this conjecture.
However, many climate scientists believed that carbon emission derived AGW would prevent such an new ice age starting (even Nigel Calder in his book The Weather Machine, which, as a result of a BBC documentary, popularised the idea of a sudden, imminent, catastrophic new ice age, accepted this) and since then we're learned much more about glacial cycles and now know that a new ice age isn't due to even start for thousands of years (and it takes tens of thousands of years for ice sheets to advance on temperate zones). Notwithstanding which, there has been a slow decline in temps, especially in Arctic regions, for the past 4-5,000 years (the neoglacial) due to reduced axial tilt: a trend which we would expect, all else being equal, to continue through the 21st century.
As an aside, carbon emission derived AGW isn't the only form of AGW

Since when did 1868 be recognized as being in the middle of the Little Ice Age ? And as for a random example .. the hottest spell in hundreds of years !?
The problem with the LIA is that when it started and when it ended depends on what you're studying. But whilst the start date varies, most authorities date the end to c1850 (although some do extend it to c1900) Hence reference to 150 years of warming.
Of course there have always been cold winters and warm summers and mild winters and cool summers. In themselves they prove nothing. Which is why pollen and glaciers are better indicators than subjective weather reports,

Light snow in Evesham - more like snizzle, but it still counts
-
Nationally, a very remarkable month.
For me though it was mostly cold and grey with only one snow fall that actually settled - and that only very briefly. Some good frosts though, making up a little for the poor winter.
-
Cant believe you dont have any snow - Im only 25 mins from you
We had a slushy covering first thing yesterday morning, but that had gone by lunchtime. Been green and muddy ever since!
As you can imagine, I find it a tad frustrating!

Commnents from 2006 and 2007 , wikipedia a 2000 study + a USA study ? Talking about now and going forward, not then. Not talking about events this year or new 'ice age' but trends to colder winters wetter cooler summers. Studies suggest these changes can happen in as little as 10 years.
Have you forgotten last Spring? Or the warm spring and autumn in 2011 (which here was an entirely snowless year, and the first autumn frosts didn't arrive until mid December) .

Where's the evidence from Britain that the growing season is getting shorter and/or spring starting later?
One year does not change a multi-decadal trend

A question .Do we have the same meandering Jetstream in the southern hemisphere and if we do what are the main drivers causing it there?
Not that I'm aware of. However, the southern jet has moved closer to the pole and it's believed that this may be linked to ozone depletion
Have you turned your central heating on yet ?

No.
But I have closed the back door this evening :o
