Warming could exceed 3.5 C, say climate scientists

The UN's target is a 2 C limit on warming from pre-industrial levels for manageable climate change
Climate researchers said the planet could warm by more than 3.5 degrees Celsius (6.3 degrees Fahrenheit), boosting the risk of drought, flood and rising seas.

Climate researchers said Thursday the planet could warm by more than 3.5 degrees Celsius (6.3 degrees Fahrenheit), boosting the risk of drought, flood and rising seas.

The UN's target is a 2 C (3.6 degree Fahrenheit) limit on warming from pre-industrial levels for manageable climate change.

In a report issued on the penultimate day of new UN talks in Bonn, scientists said Earth's average global temperature rise could exceed the dangerous 3.5 C (6.3 F) warming they had flagged only six months ago.

Marion Vieweg, a policy researcher with German firm Climate Analytics, told AFP the 3.5 C (6.3 F) estimate had been based on the assumption that all countries will meet their pledges, in themselves inadequate, to reduce greenhouse-gas emissions.

New research has found this is not "a realistic assumption," she said, adding that right now "we can't quantify yet how much above" 3.5 C (6.3 F) Earth will warm.

The monitoring tool is called Climate Action Tracker (CAT), a joint project of Climate Analytics, Ecofys and the Potsdam Institute for Impact Research in Germany.

Her colleague, Bill Hare, said the gap between countries' promised interventions and the reality was "getting bigger."

Projections are for greenhouse-gas overshoot of between nine and 11 billion tonnes per year beyond the annual 44-billion-tonne ceiling needed by 2020 to achieve the 2 C (3.6 F) target.

At the moment, the world emits about 48 billion tonnes of these gases, including CO2 and methane.

The United States accounts for six billion tonnes, China seven and the European Union (EU) five, the CAT said.

The 195 parties to the (UNFCCC) are meeting in the former German capital of Bonn for the first time since they agreed in Durban, South Africa, last December to forge a new .

The accord would be completed by 2015 and take effect in 2020.

Could exceed 3.5, love fake science of Man Made Global warming. According to Al Gore, how much more time do we have to reduce co2 levels? If I recall we only have a few years left to save the world.

Drought and flooding?

What a magical unicorn of a gas that CO2 is. It can cause drought in regions that are flooding and flooding in regions what are in drought.

Anyone who takes this hilarious propaganda is as dumb as VD.

VD is like a little foul mouthed child who believes in Unicorns, and Santa Claus and AGW conmen.

Another nail in the coffin of Not-warming-park group. It must be a big coffin; IT SURE DOES HAVE A LOT OF NAILS.

I wonder how much warming it takes for tectonics to reach such a point that it will catalyze volcanic activity.

In the last years we already had 4 eruptions if i remember correctly and that is unusual.

One wonders why ParkerTard has just finished posting that a cherry picked temperature trend from central England which represents 1/16 thousanth of the earth's surface is representative of the world as a whole.


Despite your whiny name calling, I'll answer.

"The monthly series, which begins in 1659, is the longest available instrumental record of temperature in the world. The daily series begins in 1772."

If VD has an alternative thermometer record that occurs in the 1600s, 1700s and 1800s I would graph it for him.

VD is a hateful progressive name calling bully. Don't believe me, just check out his profile.

Anyone who believes someone as hateful and spiteful as VD, deserves to be a progressive.

ParkerTard thinks that his cherry picked temperature series that covers 1/16 thousanth of the earth's surface is in any way applicable as a replacement for a true global average.


1) Its not cherry picking if it is the only 350 year long thermometer series.

2) Feel free to enlighten us with another series that long.

3) If climate derangement is global, then HADCET should be a viable temperature series.

4) As for "1/16 thousanth of the earths surface", the so-called global series such as GISS comprises about 1000 thermometers near airports or large cities and is probably reasonably representative of less than 1/16 thousandth of the earths surface.

Soo... most glaciers are shrinking, spring is coming earlier, rainfall patterns are changing, the permafrost in north Europe and Alaska is thawing out, but the denialbots "know" it is all a big conspiracy, presumably organised by Al Gore in his capacity as head of Opus Dei.
The hundred thousand data sets that support warming are all created by scientists telepathically brainwashed by the alien mind parasites (for the record, that was sarcasm).

Translation: No one buys the AGW lies anymore.

This is a compilation of 31 data sets, which include data from more than 7200 independent stations.


But not current data.

GHCN peaked around 6000 stations in the 1970s. It is down to just over 1000 now.

Nice animated graphics and article here:

And VD, HADCET is the only 350 year thermometer record. Throwing away inconvenient dat is the hallmark of AGW cultists.

Some times I wonder just how much it would take to convince the deniers. It helps that many live in a warm climate, while the effects of warming are first visible in boreal or sub-arctic regions. It is easy to ignore forests invading former tundra if you live a thousand miles further south.

Nevertheless, every citizen has an obligation to seek out information about society, even if that information is unpalatable or downright scary. It is, for instance, irresponsible to build a house on a plot that sits right across the San Andreas fault (but people still do it). It is irresponsible to let your kids go without vaccinations (but people still do it). It is up to the grownups to gather information, and try to alter policies to avoid disaster despite the apathy of deniers.

Only 2 of the stations have data up to 2012. Blaine and Clearbrook.

@Mr Notparker, here is a graph for you. It sure looks like a hockey stick to me.

Wow! Apparently if you don't drink the Algorean Kool-Aid and glom on to the AGW 'movement' you are to be attacked and referred to Wikipedia. So much hate comes from the hempies. Chill. Hit the bong.
That's what Barry Soetoro would do.

What happened to ParkerTard? Has his coal industry funding run out?


Doing research. You shoud try it some day.

"Over the past century, years in Greenland that register as abnormally warm, 1929, 1932, 1941, 1947, and 1960 are outstanding, having temperatures warmer than observed recently. Increases in GrIS melt and runoff during this past century warm period must have been significant and were probably even larger than that of the most recent last decade (1995-2006)."
