Former Vice President Al Gore’s global-warming speech Saturday night at Mizner Park drew about a thousand attendees, as well as more than 200 loud protesters.

Stationed outside the Mizner Park Amphitheater, the protesters jeered at Gore as he took the podium and at those walking into the open-air venue to listen to the speech.

“This is the most dangerous crisis we’ve ever faced,” Gore said of climate change. He spoke over a chorus of boos from protesters, who were monitored by at least a dozen uniformed city police officers.

Many of the protesters were with the groups Collegians for a Constructive Tomorrow and South Florida Tea Party, the latter of which feels that Gore’s views will eventually lead to increased taxes and flawed business legislation.

The protesters carried drums, bullhorns and posters. One read “Practice what you preach,” accusing Gore of not living a green lifestyle. Another poster read “The masses follow the asses,” depicting the protesters’ opinion that Gore’s message is not backed by scientific evidence.

Lord Smith of Finsbury believes that implementing individual carbon allowances for every person will be the most effective way of meeting the targets for cutting greenhouse gas emissions.

It would involve people being issued with a unique number which they would hand over when purchasing products that contribute to their carbon footprint, such as fuel, airline tickets and electricity.

Like with a bank account, a statement would be sent out each month to help people keep track of what they are using. If their “carbon account” hits zero, they would have to pay to get more credits.

Al Gore has sought to inject fresh momentum into the Copenhagen build-up, saying he is certain Barack Obama will attend and predicting a rise in civil disobedience against fossil-fuel polluters unless drastic action is taken over global warming.

Amid increasing incidents of climate protesters disrupting the operations of fossil-fuel industries and airports in Britain and elsewhere, Gore suggests the scale of the emergency means non-violent lawbreaking is justified. “Civil disobedience has an honourable history, and when the urgency and moral clarity cross a certain threshold, then I think that civil disobedience is quite understandable, and it has a role to play,” he says. “And I expect that it will increase, no question about it.”

In his only UK newspaper interview to mark the publication of his new book, entitled Our Choice, Gore says it is crucial for Obama to attend Copenhagen in person, adding: “I feel certain that he will.”

I’m by no means a man made climate change sceptic, and I fervently believe that dissent is the essence of a democracy, but isn’t Gore essentially calling for revolution? I’m uneasy about this guy’s motives.

Fertility is falling and families are shrinking in places— such as Brazil, Indonesia, and even parts of India—that people think of as teeming with children. As our briefing shows, the fertility rate of half the world is now 2.1 or less—the magic number that is consistent with a stable population and is usually called “the replacement rate of fertility”. Sometime between 2020 and 2050 the world’s fertility rate will fall below the global replacement rate.

At a time when Malthusian worries are resurgent and people fear the consequences for an overcrowded planet, the decline in fertility is surprising and somewhat reassuring. It means that worries about a population explosion are themselves being exploded—and it carries a lesson about how to solve the problems of climate change.

Today’s fall in fertility is both very large and very fast. Poor countries are racing through the same demographic transition as rich ones, starting at an earlier stage of development and moving more quickly. The transition from a rate of five to that of two, which took 130 years to happen in Britain—from 1800 to 1930—took just 20 years—from 1965 to 1985—in South Korea. Mothers in developing countries today can expect to have three children. Their mothers had six. In some countries the speed of decline in the fertility rate has been astonishing. In Iran, it dropped from seven in 1984 to 1.9 in 2006—and to just 1.5 in Tehran. That is about as fast as social change can happen.

On the other hand:

The Malthusians are right that the world’s population is still increasing and can do a lot more environmental damage before it peaks at just over 9 billion in 2050.

On a vaguely related topic, many Chinese never learned how not to get pregnant.

Environmental groups say the oil leak spilling into the Timor Sea should be declared a national emergency, with one expert likening it to a ”disaster movie”.

The situation has worsened in the last 24 hours with a fire breaking out on the deck of the West Atlas rig and Montara well head platform, when the company responsible for its operation began to plug the rig’s leak below the sea bed with mud.

The Toyota flower gets loose

Car maker develops its own flower species – drive.com.au

Toyota has created two flower species that absorb nitrogen oxides and take heat out of the atmosphere.

The flowers, derivatives of the cherry sage plant and the gardenia, were specially developed for the grounds of Toyota’s Prius plant in Toyota City, Japan.

The sage derivative’s leaves have unique characteristics that absorb harmful gases, while the gardenia’s leaves create water vapour in the air, reducing the surface temperature of the factory surrounds and, therefore, reducing the energy needed for cooling, in turn producing less carbon dioxide (CO2).

The two new plants are part of a wide-ranging plan to reduce the impact of Prius manufacture on the environment. Since 1990, the plant has reduced CO2 emissions by 55 per cent.
