Stew you say that thirty years after the first IPCC reports we are still waiting for global warming. But, how can you be so sure? Have you run an experiment with another Earth that has had no human influence upon it's atmosphere?

Why public confidence in science is eroded? Or not.

Thanks for the link Stew, that's (overall) an excellent article from the Independent. It makes the point about a Govt tipping point being crossed, about 400pmm of CO2 (which we are passing, equivalent or not)) that such a level is likely to bring 2C warming and that aerosols might mask that warming. Valid then, just as valid now. Why aren't we seeing rapid warming? Aerosols?

I see New Zealand is now importing our media rubbish on climate change.

From your article.

 

"Despite the arrival of spring, the icy grip of winter still retains a stranglehold on much of the Midwest and Northeast. The 2013-14 winter season is one of the coldest winters in 20 years, according to AccuWeather Senior Meteorologist Dave Dombek.

"It's probably the coldest the Northeast has seen since 1993-94," he said in early March"

 

The 'coldest in twenty years' refers to just part of the US, across the country as a whole an unremarkable winter. 

 

Anyway,  we are all (bar Keith  ) agreed the 'coldest in 105 years' claim is nonsense?

A few graphs regarding the winter. I think you will find in some areas coldest since 1979 but I'll stick in the US minus Alaska as well. Oh and Arizona and California.

Watch Episode 1 of James Cameron's "Years of Living Dangerously"

 

After a long period of development, James Cameron’s terrific and powerful mega-project on climate change, “Years of Living Dangerouslyâ€, opens today on Showtime.  The first hour installment of the 9 part series features glimpses of climate change impacts around the planet through the eyes of well known guides.  The first episode is free online and can be watched above.

 

The series sets a dramatic, powerful urgent tone. The first episode takes the bull by the horns – crisscrossing the planet to take snapshots of climate impacts, and the processes behind them, through the eyes of those impacted.

 

Don Cheadle explores  drought impacts in the US Southwest. Maybe not so surprising – the very people who are being crushed by the impact of climate change, lower class rural folk in Texas, are unable to make a connection between global climate and their problems. They prefer to believe the problems come from God, or natural cycles.  Climate Scientist Katharine Hayhoe is profiled in her battle against entrenched attitudes and scientific ignorance in that part of the world.

 

Tom Friedman looks into the impacts of drought on the drought fueled civil war in Syria, and Harrison Ford journeys into the Borneo rainforest, where mega-corporations and corruption are turning massive forest reserves of carbon, and the wildlife it supports, into smoke and greenhouse gas.

 

If the first installment is any indication, this is a major contribution. The question is how best to spread it beyond the premium cable audience. Taking some time to watch this first hour is a good first step.

The climate community traditionally underestimates the rate of change in the climate system, Columbia University scientist Maureen Raymo cautions, raising questions about where things will stand once everything “comes into equilibrium†with the Pliocene era atmosphere we’re now experiencing.

This blasted pause just won't stop pausing

 

  TempLS global temp up 0.27°C in March

 

TempLS showed a large rise from February to March, more than balancing the large drop to February. The global average anomaly rose from 0.305°C to
0.575°C. The satellite indices showed little movement.

Here is the spherical harmonics plot of the temperature distribution. I've made some changes this month. I used a different and I think better scheme for truncating to a finite basis set. That seems to let me get better resolution, so I have resumed showing the polar regions as well. I have also improved the color matching with GISS.

Take note Stew.

 

 

 

Yes, interesting analysis. Updated to include years to 2010.

 

Here's what it looks like,

 

 

(I reject this, thoroughly, btw; primarily because climate series are derived from 30 year averages, so the minimum dataset for trend analysis should be .... ahem ... 30 years. Also, that's only if you think that least linear squares is worthwhile on a timeseries)

The claim that increasing CO2 levels may be beneficial is wrong.

Hurricanes Likely to Get Stronger & More Frequent: Study

 

Hurricanes are Mother Nature’s largest and most destructive storms. Fed by warm ocean waters and moist atmospheric conditions, about 90 such storms — also known as tropical cyclones — form worldwide each year. With the population of coastal areas growing daily and sea level on the rise, how these monster storms may change as the climate continues to warm is an increasingly urgent question facing climate scientists, insurance companies, and public officials.

'Leslie Woodcock' Who? Never heard of him.

 

Oh, he's "A prominent environmental scientist "? What? A "emeritus professor of chemical thermodynamics" is an environmental scientist? Are you are trying to mislead us Keith, or is the article doing that?

Cities on frontline of climate change struggle

 

Half of the world's population now lives in cities - a proportion that's set to rise to two-thirds by 2050. Yet cities are vulnerable to the worst impacts of climate change precisely because their locations are fixed. As the UN's climate panel meets in Berlin, how are urban centres coping with the test?
