Out of Africa: Nigerian environment minister warns of devastating climate impacts

The government in New Zealand may make soothing noises about climate change impacts, but that is not an option for the Minister of Environment in Nigeria, Mrs Laurentia Mallam. She issued this chilling warning about the impacts of sea level rise a few days ago:

“Studies have projected that with an accelerated sea level rise of 0.5 meters, 35 per cent of the Niger Delta land mass will be lost, and with accelerated sea level rise of 1.0 meters, 75 per cent of the Niger Delta will be gone under water.

“Given this scenario, it implies that nearly 32 million people (22.6 per cent of the national population) who live along the coastal zone are at the risk of becoming environmental refugees. Such forced movement could result in social frictions arising from demands of land resources for economic activities by the refugees.”

For good measure she listed the full effects of climate change on her country:

“In Nigeria, the impacts of climate change are manifested by erosion and landslides in the east, drought, and desertification in the north, raising sea levels in the coastal areas and flooding across the nation.”

The adaptation measures required by Nigeria will obviously be of staggering proportions, and add urgency to the need to prevent the problem from getting even worse than it is already going to be.

Taxing Rodney: Hide’s carbon hypocrisy

Untroubled as he is by the responsibilities of public office, or any apparent need to appear consistent, the former leader of the far-right ACT Party, Rodney Hide, attempts to ridicule the Green Party’s new carbon tax policy in his column at the National Business Review this week. You can’t actually read the column, because it’s behind a paywall, but the ever-helpful Cameron Slater at Whale Oil comes to the rescue by copy/pasting all the best bits. Here’s Hide, 2014 style:

We desperately need the Russel-Norman. A tax to deal to a problem bigger than World War II, the Depression and the Plague all at once.

We must go Green, save the planet and get rich. What a plan! What a vision!

Years ago an old man grumbled to me. GST. Bah. He didn’t think taxing food was right. “What’s next? The air we breathe?” Nope. Our new tax is on a trace gas that we all breathe out.

But those of us with functioning memories will recall that back when Rodney was ACT leader and a minister in a National-led government — only six years ago — he was advocating that the Emissions Trading Scheme be dropped and replaced by — wait for it — a carbon tax. Here’s Rodney in 2010, talking to Guyon Espiner on TV1:

We don’t think we should be doing anything, but what we’ve said is, if you were going to do something, it would be far cheaper and far easier just to put a low tax across fossil fuels. That would achieve the same result, you could also subsidise forestry, and we’ve offered that up to the National Party as an alternative that would be easier. Why would it be easier? It would administratively much less costly, because you’d just put a tax across rather than try and operate a trading mechanism…

I think I sort of understand what’s going on in Rodney’s head. When he was trying to be an electable politician, he at least made an effort to make sense. Now that he’s just another libertarian ideologue with a soapbox he can say whatever he wants, and the green-hating rabid right so ably fed and watered at Slater’s blog will lap it up. Meanwhile, out in the real world, perhaps a carbon tax’s time has come…

Antarctica’s melting, seas will rise: here’s why

[youtube=https://www.youtube.com/watch?v=71l9lzLsBRc&w=480]

How is Antarctica melting? Much faster than we hoped, according to the latest research — neatly explained in the latest Peter Sinclair This Is Not Cool video for Yale Climate Connections (formerly the Yale Forum), cunningly titled Meltwater Pulse 2b. Just how fast the West Antarctic Ice Sheet will melt, and how much East Antarctica will contribute to near term sea level rise is open an open question, but the news is not good, as the latest research on the stability of the Antarctic ice sheet at the end of the last ice age suggests.

TDB Today: Put a proper price on carbon

The Green Party’s shift to a carbon tax as their preferred measure to to bring down carbon emissions opens up some interesting possibilities, as I discuss in my Daily Blog post this week: Put a proper price on carbon or we’ll pay a proper price.

As long as governments have a completely free hand, and are backed by vested interests with deep pockets, they’ll screw up carbon policy. They’ll do it at every opportunity. So let’s take some of the levers out of their hands, and give them to someone with a legislated requirement to act in the best interest of all New Zealanders.

We do it for economic policy through the governor of the Reserve Bank of New Zealand. Why not for emissions reductions?

Climate Change and the Course of Global History

The title in the Kindle Store was irresistible: Climate Change and the Course of Global History: A Rough Journey. American historian John L Brooke is the author, and the book is notable for its attempt to integrate climate science with the study of human history. In his acknowledgements the author brackets climate scientists with historians and archaeologists in the long list of people with whom he has corresponded and from whom he has received data and an understanding of scientific culture.

The scope of the book is as wide as human emergence in the evolutionary process, and before. It’s not my purpose to track through the long story the author has to tell or to follow the intricacies of the climate shifts he refers to. The book demands and rewards patient reading in these respects. But I offer a few comments arising from my reading of the book.

An historian making the effort to understand climate science as thoroughly as Brooke does seems to me in itself worth remarking. Often I could have been reading one of the many books by scientists or science writers that I’ve reviewed over past years on Hot Topic. The culture gap between the sciences and the humanities that C P Snow’s famous 1959 lecture lamented was certainly not evident in Brooke’s history. Five years ago I reported the plea of biographer Richard Holmes at the Hay Festival that we reject the notion of two cultures and accept the duty to understand the scientific discoveries of the modern age, a duty of crucial importance in the face of global warming. Brooke has clearly accepted that duty, though I fear many educated in the humanities continue to excuse themselves from it.
