1. Obama rejects the Keystone pipeline

Obama has rejected the proposal to build a pipeline to bring tar sands oil south from Canada to refineries in the Gulf Coast.

    Obama said Friday that the State Department, in its final Environmental Impact Statement, found that the pipeline would not be in the country’s national interest. “I agree with that decision,” he said.

1. Hunt stacks Climate Change Authority with Coalition advisors and ex MPs

The Climate Change Authority has been a thorn in the side for the Abbott Government, as we’ve seen over time. The Abbott government tried to kill the Authority, but was thwarted by the Senate.

Now Bernie Fraser, John Quiggin, David Karoly and other good people have been replaced by a bunch who support Direct Action as a policy and seem less than enthusiastic about renewable energy. If the comment by Larissa Waters at the end of the linked piece is correct the Nationals did a “deal with Malcolm Turnbull to keep Tony Abbott’s woeful climate policies in exchange for support.” Continue reading Climate clippings 154

1. Shorten gets solar + storage and the energy revolution

It’s happening, he says, through the action of consumers and industry.

    “This is a consumer revolution, as much as it is an energy transformation empowering Australian households, communities and businesses,” Shorten said. (It is) putting control back in the hands of the user, shifting the balance away from big power companies.”

1. New beaut solar technology from UNSW

PERC technology developed by UNSW is likely to become standard in more than half of all solar cell production across the globe by 2020, ushering in new dramatic falls in the cost of solar technology. Continue reading Climate clippings 147

Renewables roundup: Daniel Andrews winds up wind

From Facebook:

    Victoria continues to be the country’s best location for renewable energy investment, thanks to planning changes which will streamline wind farm project approvals.

    Applications made for new wind farms under the Andrews Labor Government will now be simpler, encouraging investment and jobs growth in regional areas.

    In Victoria, we currently have 19 wind farms that have planning approval but are yet to be commissioned. Continue reading Renewables roundup: Daniel Andrews winds up wind

The future of electricity in Queensland

As noted in Climate Clippings 139 (Item 5) the new Queensland Labor Government has committed to a 50% renewable energy target by 2030 so I was interested to attend a public forum last week on the future of electricity in Queensland, chaired by John Davidson as convenor of the West Brisbane Branch of the Queensland Greens. Speakers were John Foster, Professor of Economics at Queensland University, Murray Craig, Managing Director of Solar Centre and Charles Worringham, spokesperson for the Queensland Greens.

1. Unburnable Carbon: Why we need to leave fossil fuels in the ground

That’s the title of a new report from the Climate Council.

    To have a 75% chance of meeting the 2°C warming limit, at least 77% of the world’s fossil fuels cannot be burned.

1. Mt Everest’s poo problem

Every year climbers of Mt Everest leave behind 26,500 pounds of poo. I make that about 12 tonnes.

Sherpas pick it up, bring it down in blue barrels, dig a hole and dump it. Now the proposal is to build an anaerobic digester in a small village near Everest’s base to create biogas to produce power. Apparently human poo is not the best, but it works.

2. Arctic sea ice record

I think it’s time to call it. The Arctic sea ice winter maximum is the lowest on record. This graph shows 2015 ice against the previous record of 2011 and the 1981-2010 average:

sea ice_Feb 25_cropped_600

Also the maximum extent was reached on February 25, the second earliest on record.

According to a recent survey, thinning has been quite dramatic:

… annual mean ice thickness has decreased from 3.59 meters [11.8 feet] in 1975 to 1.25 m [4.1 feet] in 2012, a 65% reduction. This is nearly double the 36% decline reported by an earlier study….

In September the mean ice thickness has declined from 3.01 to 0.44 m [from 9.9 to 1.4 feet!], an 85 % decline.

Climate Central has a graphic showing the loss of ‘old’ ice. In 1987 it used to be 26% of the ice pack, now it’s down to 10%.

Polar bears will struggle to adapt.

3. Shell looks to drill in Arctic

Shell hopes to drill in the Chukchi Sea in the Arctic this summer. It looks as though Obama’s Department of the Interior will allow it, even though an Environmental Impact Report released by the Bureau of Ocean Energy Management (BOEM) noted a 75% chance of one or more large spills occurring under the current plan. In 1989 the Exxon Valdez disaster spilled nearly 11 million gallons of crude oil into the Alaskan Gulf, polluting over 1300 miles of coastline. It is estimated that only 14% of the oil was cleaned up.

By comparison BP’s Deepwater Horizon oil rig spilled 168 million gallons of oil into the Gulf of Mexico off the Louisiana coast.

Yet Obama himself stresses the need to move early on climate change. More than half of Republican politicians deny or question the science. Voter pressue will change that eventually.

A recent Stanford University poll found that two-thirds of voters were more likely to vote for a candidate that campaigned on a platform of fighting climate change, and were less likely to vote for a candidate that outright denies climate change.

4. Land, ocean carbon sinks are weakening

We are destroying nature’s ability to help us stave off catastrophic climate change. That’s the bombshell conclusion of an under-reported 2014 study, “The declining uptake rate of atmospheric CO2 by land and ocean sinks,”…

Based on actual observations and measurements, the world’s top carbon-cycle experts have determined that the land and ocean are becoming steadily less effective at removing excess carbon dioxide from the atmosphere. This makes it more urgent for us to start cutting carbon pollution ASAP, since it will become progressively harder and harder for us to do so effectively in the coming decades.

Joe Romm calls the study “one of the most consequential recent findings by climatologists”

More than half of emissions are currently absorbed by land and ocean-based carbon sinks. Increasingly these emissions will stay in the air.

5. Reasons the Australian solar market is so interesting

Clean Technica has found 7 reasons the Australian solar market is so interesting republished at RenewEconomy.

One reason is that we have so much sunlight, as shown below:

solar-australia

However, most of us live in the more cloudy parts in big cities and along the south-east edge. A commenter pointed out that for insolation Ney York lies between Melbourne and Sydney.

A second reason is that we are enthusiastic about roof-top solar, with over 20% of houses now with panels installed.

A third is that, along with Germany, Italy and The Netherlands, we reached socket (aka grid) parity in 2013.
