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

Sea level risk worsens: Need for greater urgency as Arctic ice melting faster

The ice of Greenland and the rest of the Arctic is melting faster than expected and could help raise global sea levels by as much as one and half metres this century, dramatically higher than earlier projections, an authoritative international assessment says.

The findings ’emphasise the need for greater urgency’ in combating global warming, says the report of the Arctic Monitoring and Assessment Program (AMAP), the scientific arm of the eight-nation Arctic Council.

The melting of Arctic glaciers and ice caps, including Greenland’s massive ice sheet, is projected to help raise global sea levels by 90 to 160 centimeters by 2100, AMAP said, although it noted that estimate was highly uncertain.

Now the AMAP assessment finds that Greenland was losing ice in the 2004-2009 period four times faster than in 1995-2000.

The last bit is interesting, the rest is not news, except that the article appeared in the Courier Mail. Probably just a page-filler grabbed off the wires. Turn over a few pages and there was a column by Jennifer Marohasy. Normal service restored. Continue reading Climate clippings 25

These posts include a brief mention of a number of news items relating to climate change. They don’t preclude treating any of these topics at more length in a separate post.

They can also serve as an open thread so that we can keep each other informed on important climate news.

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…
