This edition is somewhat themed around climate policy and planning in China, the US and Australia. It also includes items on puffins in Maine, the Lowy Institute poll and the warm weather we’ve been having in May.

1. Petey Puffin dies on camera

Puffin_maine_500

Puffins were once common on the coast off Maine but were eliminated by overhunting. In recent years there has been a project to repopulate the area, which was proceeding well accompanied by a cam project where children around the world could watch the birds in their habitat. Petey Puffin, a chick being fed by its parents became a popular focus. The only problem was that the parent birds kept bringing him butterfish which were just too large for him to swallow. This went on day after day until the chick died on camera.

The project co-ordinator then checked the 64 other burrows being monitored to find that only 30% of chicks survived.

Problem was that hake and herring normally abundant around Maine had moved north as the water warmed to be replaced by butterfish.

The warmer water brought many other changes to the waters off Maine.

Incidents such as these remind people that they are living in the midst of climate change.

2. President Obama gets serious on climate change

From John Abraham at Climate Consensus – the 97%:

President Obama just announced a major effort to reduce global-warming gases from United States power plants. These new rules, and his prior strong actions on climate change, signify a major shift for the United States. No longer is the U.S. the world laggard on dealing with climate change – we are quickly becoming the leader.

We finally have a president that understands science. We finally have a president that honestly includes scientists as decision makers – rather than effectively muzzle them. We finally have a president that recognizes the social and economic costs of climate change. We finally have a president who is charting a pathway that may lead us to bend the curve of emissions downward so that the most serious climate change consequences are avoided.

Most importantly, we finally have a president who is a world leader.

3. Not everyone is happy

John Podesta before rejoining the White House inner circle in an interview said history will not applaud the measures taken by Obama as it fails to meet what the science demands. It won’t limit us to a 2°C temperature rise, and 2°C is too dangerous.

A 30% reduction by 2030 from 2005 levels shrinks to 7.7% if you use the international baseline of 1990. Moreover, coal will be replaced by gas, where the ‘fugitive’ methane emissions are not counted.

Podesta says that in Obama’s first term his top aides never took climate change seriously. Ironically, Podesta as Obama’s transition director in 2008 helped select those aides.

4. China to cap emission

China will seek to cap fossil fuel emissions for the first time, we are told.

Reading carefully it seems that emissions will still grow, but not as fast as business as usual.

Pointing out that there are 1.6 billion people in the US and China, Amanda McKenzie CEO of Climate Council thinks the decisions are a game changer.

5. Time for Tony Abbott to admit his climate policy is crap

In case you missed it, that is Giles Parkinson’s advice to Abbott.

Parkinson says Australia should be embarrassed by its lack of action compared to the United States and China, which has indicated it will place a cap on its emissions as soon as 2016.

Ironically, Abbott could have a pretty good collection of climate and renewable energy policies just by doing nothing. Everything Labor put in place is still there, apart from Tim Flannery and the Climate Commission, which has morphed into the Climate Council with private money and public donations.

6. Lowy poll

The Lowy Institute Poll 2014 is now available.

The number of Australians now saying global warming is a “serious and pressing problem” and that “we should begin taking steps now even if this involves significant costs” is now 45%.

Some 38% now say the the problem of global warming should be addressed, but its effects will be gradual, so we can deal with the problem gradually by taking steps that are low in cost. 15% think we should leave it until we are sure it’s a problem if costs are involved. Here’s the graph:

Lowy poll 1_cropped_600

63% of people thought the government should be taking a leadership role in reducing emissions.

Lowy poll 2_cropped_600

I guess Abbott would claim that’s what they are doing.

7. Heat wave in May

Will Steffen talks here and here about the unusually warm period in May, which I believe officially rates as a heat wave.

A remarkable, prolonged warm spell occurred over the period 8-26 May, with daytime temperatures 4 to 6°C above normal over much of south-central Australia, extending from South Australia and northwest Victoria into Queensland and the Northern Territory.

The Scientific American noticed.

BOM think we are in for a warm winter:

Tokelau leads the world!

I’ve been looking for some positive stories for Christmas. What can be more positive than Tokelau going almost completely to renewables?

I guess it helps if you’ve got only 1,500 people and three cars.

Harnessing desert sun power

We’ve posted before on Desertec, the plan to generate solar power in North Africa and pipe it to Europe, to supply up to 15% of its energy by 2050. They expect to see the first solar electricity flowing from Morocco to Spain as early as 2014.

This report tells us that Morrocco itself “wants to produce 42% of its electricity from renewable sources – solar, wind and hydro-electric – by 2020.” That’s got to be good.

There are critics, however:

Valentin Hollain of Eurosolar, a German non-profit organisation that promotes renewable energy, queries the entire concept of Desertec.

He argues that big corporations are using large-scale projects like Desertec and Medgrid to retain their position into the next generation, and that a mix of renewable power supplied locally can meet demand while keeping prices down for consumers.

7 billion and counting

With the world’s population passing 7 billion there have been reports and analysis all over the media.

George Monbiot, clear-headed as usual, says the real problem is consumption. He also takes a look at the UN calculations, and is not impressed, but one way or another the graph is going to go up for about four decades.

Fred Pearce is not an economist, but he may have a point in saying that ageing is the trend and with that your economy goes down the tube. Japan has become the land of the setting sun.

Those two are part of The Guardian’s Crowded Planet series. Our ABC has 7 challenges for 7 billion put together by 7 academics. Continue reading Climate clippings 52 →

Greenland ice loss

The rate continues to accelerate, according to Skeptical Science.

It looks ugly, but see comment 24 and the correction @ 27. Doubling the rate each decade will give you 3,200 gt each year by 2050. But that’s still only a bit less than 9mm pa of sea level rise, according to my calculations. Concerning, certainly, but not yet catastrophic. Continue reading Climate clippings 48 →

EV motor racing is about to begin

The article is behind the paywall, but New Scientist reports Federation Internationale d’Automobile (FIA), is calling for proposals for a “Formula E”, an electric vehicle championship it hopes will kick off in 2013. They claim the series will drive EV technology, but hey, let’s have some fun along the way.

Meanwhile at the Mazda Raceway at Laguna Seca, California on 26 November, we will have the EV Cup. In this race all drivers will have the same vehicle, the iRacer (above), built by UK firm Westfield Sportscars. Each car will have 340 kilograms of lithium iron phosphate (LiFePO4) batteries that, for safety, are distributed around the car in eight 50-volt units. That should keep them screaming around the track for 15 to 20 minutes.

And screaming is the operative word. EV cars at speed do make a noise, but the acoustics are being designed to sound like the Pod Racers in Star Wars. Continue reading Climate clippings 47 →

Predicting tipping points

Tim Lenton is now attempting to link the basic theory of climatic “tipping points” with observed early warning signals.

Problem is, these tipping points may not be sudden and dramatic but involve a steady but inevitable increase. When outbreaks of pine beetles first became obvious perhaps the eventual destruction of Canada’s boreal forests was inevitable. But Lenton is making an argument “from almost a mathematical point of view” that there are general properties of tipping points. Continue reading Climate clippings 39 →

Joplin tornado

Link between tornadoes and climate change

Recent bad weather in the US, for example the tornado which mashed Joplin, Missouri, has led to many many stories speculating about the link between the intense tornado season and climate change. Joe Romm at Climate Progress takes a measured view:

1. When discussing extreme weather and climate, tornadoes should not be conflated with the other extreme weather events for which the connection is considerably more straightforward and better documented, including deluges, droughts, and heat waves.

2. Just because the tornado-warming link is more tenuous doesn’t mean that the subject of global warming should be avoided entirely when talking about tornadoes.

Joe Romm’s substantive post Tornadoes, extreme weather, and climate change is well worth a read and has lots of comments and links about extreme weather in general as well as tornadoes. Continue reading Climate clippings 28 →

I’ve been on holidays for a bit. Here are some links that I saved from a few hours spent on my daughter’s computer last week by checking some of the usual sources. In the next few days I’ll check the feeds and see whether there are more links to share.

E10 debacle puts the brakes on biofuels in Germany

German motorists have shown uncommonly good sense by not buying the biofuel mixture E10.

The real reason, though, was confusion over which car models could use the stuff without harm. Meanwhile a study found that:

up to 69,000 square kilometers (about 27,000 square miles) of forest, pasture and wetlands would have to be cultivated as farmland to satisfy the future demand for biofuel in Europe alone. This is an area twice the size of Belgium. One consequence of such cultivation would be the release of up to 56 million tons of CO2 a year, or the equivalent of the emissions of an additional 12 million to 26 million cars on European roads.

Climate change and the Murray Darling Basin

With record rainfall in large parts of Australia in recent months there has been a bit of a tendency to think that normal service has been returned. But record rainfall is by definition exceptional. This is how the last three months look on the BOM maps: Continue reading Climate change and the Murray Darling Basin →

What can save the majestic rainforests of West Kalimantan?

19 Comments

One of the most depressing articles I’ve read in a while is Borneo’s majestic rainforest is being killed by the timber mafia recently in The Guardian. This comes on top TV programs on of what seem like futile attempts to save the Orangutan. Wikipedia tells us:

The total number of Bornean orangutans is estimated to be less than 14 percent of what it was in the recent past (from around 10,000 years ago until the middle of the twentieth century) and this sharp decline has occurred mostly over the past few decades due to human activities and development.

The IPCC AR4 report put the net emissions from forestry at 17.4% of the total:

Coral bleaching hits the Coral Triangle

24 Comments

From the ARC Centre of Excellence for Coral Reef Studies:

International marine scientists say that a huge coral death which has struck Southeast Asian and Indian Ocean reefs over recent months has highlighted the urgency of controlling global carbon emissions.

Many reefs are dead or dying across the Indian Ocean and into the Coral Triangle following a bleaching event that extends from the Seychelles in the west to Sulawesi and the Philippines in the east and include reefs in Sri Lanka, Burma, Thailand, Malaysia, Singapore, and many sites in western and eastern Indonesia.

“It is certainly the worst coral die-off we have seen since 1998. It may prove to be the worst such event known to science,” says Dr Andrew Baird of the ARC Centre of Excellence for Coral Reef Studies and James Cook Universities. “So far around 80 percent of Acropora colonies and 50 per cent of colonies from other species have died since the outbreak began in May this year.”

This means coral cover in the region could drop from an average of 50% to around 10%, and the spatial scale of the event could mean it will take years to recover, striking at local fishing and regional tourism industries, he says.

The bleaching event has also hit the richest marine biodiversity zone on the planet, the ‘Amazon Rainforest’ of the seas, known as the Coral Triangle (CT), which is bounded by Indonesia, Malaysia and the Philippines.
