GLOBAL warming is unusual

A common response to AGW warmists is that climate has always changed and always will. It’s natural and humans have nothing to do with it. Now via Climate Progress we learn from a study by Svante Björck of Lund University that apart from general moves into and out of ice ages the hemispheres do not warm or cool in sync. When one hemisphere changes the other stays the same or moves in the opposite direction. For example he found that during the Little Ice Age in Europe there were no corresponding changes in the southern hemisphere.

Last week I posted this graph to show that we are giving the system a helluva jerk. In fact we need to go back 15 million years to find CO2 levels as high as today. (if you are concerned about Antarctic thawing be very afraid.)

However, the following graph shows that the hemispheres are not perfectly in sync now:

Hemispheric land-ocean temperatures

The northern hemisphere is pulling away. The reason, presumably, it has more land, and at higher latitudes. Continue reading Climate clippings 53 →

Sceptical ‘science’

For many in Australia on climate change Bob Carter is the man. Tamino at Open Mind got access to his slides and took a look at how he does temperature trends. Turns out he doesn’t. What we get is the most outrageous and blatant cherry-picking.

See also Deltoid.

John Abraham took a look at how Monckton cites scientific literature on the Mediaeval Warm Period. Abraham emailed a sample of the cited scientists to find Monckton achieved perfect score for misrepresentation.

More at Quiggin’s here and here and some good journalism at Background Briefing. Continue reading Climate clippings 36 →

Hurricane Katrina

Severe weather alert: a busy hurricane season

That’s the forecast for 2011.

The US National Oceanic and Atmospheric Administration (NOAA) is predicting a 70 per cent chance of 12 to 18 named storms, six to 10 of which are likely to reach hurricane force – with wind speeds of at least 119 kilometres per hour.

A normal season would have 11 named storms, six of them hurricanes. During 2005, which brought us Katrina, there were 28 named storms. Continue reading Climate clippings 31 →

Renewables need consistent policy

From Climate Spectator:

Andrew Garrad, the founder of Garrad Hassan, the world’s largest renewable energy consultancy, has an interesting way of describing Australia’s stop-start renewable energy policy. It goes something like this, in binary code, where nought represents a step backwards, and one represents an advance: 100101100101011010010. The point he’s making is that, more than anything, renewables need consistent policy. And in Australia, and elsewhere in the world, that has been clearly lacking.

The rest of the article is worth reading. Greg Hunt shows what it would be like to have a climate change minister who is interested in climate change.

The Koreans show how to pick winners:

he suspects the future may be dominated by the Korean companies who have become household names in electrical appliances. The likes of Samsung and Hyundai are investing huge sums into clean-tech. “They are going to do things, very fast and well.”

Hunt picks algae as a winner “echoing predictions that it could emerge as a $20 billion industry.” Continue reading Climate clippings 26 →

The permafrost giant is stirring

We predict that the PCF [permafrost carbon flux] will change the Arctic from a carbon sink to a source after the mid-2020s and is strong enough to cancel 42–88% of the total global land sink. The thaw and decay of permafrost carbon is irreversible…

California approves first broad US climate plan

California has approved “the most sweeping US plan to reduce greenhouse gas emissions”.

It includes a cap-and-trade plan:

Initially, California will technically not restrict emissions but instead freely allocate “allowances” to businesses covering their carbon output. The state will gradually reduce allowances, forcing firms to go green.

Companies can also earn credit by supporting environmental projects in forests or farms, including through preservation of woods in Mexico’s Chiapas state and Brazil’s Acre state.

Not everyone is happy, as the scheme could involve clear-felling to plant trees.

There’s more at Climate Progress. Continue reading Climate clippings 8 →
