Till your well runs dry: NZ drought hits record levels

Australia may have had an extraordinary “Angry Summer“, but New Zealand’s been having a bit of a cracker too. Prolonged warm and sunny weather over much of the country has driven North Island soil moisture deficits to levels not seen for at least 70 years (see map at left). Official drought status — which means farmers are eligible for various forms of government assistance — has been declared in Northland, South Auckland, Coromandel, Bay of Plenty, Waikato, and Hawke’s Bay. The Manawatu and Rangitikei regions have also asked government for drought status. Most of the North Island is also subject to total fire bans — another first for this dusty summer. Preliminary estimates of economic losses are already heading towards $1 billion.

Stuff.co.nz noted the obvious climate connection:

Long, dry spells are forecast to double by 2040 as temperatures continue to rise and New Zealand heads towards a more Mediterranean climate.

Experts warn it could spell the end for farming as we know it and may cost the country billions of dollars in drought relief each year before practices are adjusted.

“This is historic,” said climate scientist Jim Salinger, who has calculated that the amount of rain needed for grass growth was the highest since records began. “It’s like comparing your income against expenditure in your cheque book. And we are in deficit.”

The year the earth bit back: top climate stories of 2012

2012Amidst the blizzard of year-end roundups, here’s one you have to read in full — a joint effort put together by a diverse group of bloggers and scientists: Angela Fritz, Eli Rabett, Emilee Pierce, Greg Laden, Joe Romm, John Abraham, Laurence Lewis, Leo Hickman, Michael Mann, Michael Tobis, Paul Douglas, Scott Mandia, Scott Brophy, Stephan Lewandowsky, Tenney Naumer and yours truly. Lead author Greg Laden explains:

A group of us, all interested in climate science, put together a list of the most notable, often, most worrying, climate-related stories of the year, along with a few links that will allow you to explore the stories in more detail. We did not try to make this a “top ten” list, because it is rather silly to fit the news, or the science, or the stuff the Earth does in a given year into an arbitrary number of events. (What if we had 12 fingers, and “10” was equal to 6+6? Then there would always be 12 things, not 10, on everyone’s list. Makes no sense.) We ended up with 18 items, but note that some of these things are related to each other in a way that would allow us to lump them or split them in different ways. See this post by Joe Romm for a more integrated approach to the year’s events. Also, see what Jeff Masters did here. We only included one non-climate (but related) item to illustrate the larger number of social, cultural, and political things that happened this year. For instance, because of some of the things on this list, Americans are more likely than they were in previous years to accept the possibility that science has something to say about the Earth’s climate and the changes we have experienced or that may be in the future; journalists are starting to take a new look at their own misplaced “objective” stance as well. Also, more politicians are starting to run for office on a pro-science pro-environment platform than has been the case for quite some time.

A failing of this list is that although non-US based people contributed, and it is somewhat global in its scope, it is a bit American based. This is partly because a few of the big stories happened here this year, but also, because the underlying theme really is the realisation that climate change is not something of the future, but rather, something of the present, and key lessons learned in that important area of study happened in the American West (fires) the South and Midwest (droughts, crop failures, closing of river ways) and Northeast (Sandy). But many of the items listed here were indeed global, such as extreme heat and extreme cold caused by meteorological changes linked to warming, and of course, drought is widespread.

Welcome to the rest of our lives

Here’s an excellent new video from Peter Sinclair, contrasting the recent weather disasters in the USA with the “we’ll adapt” line recently run by ExxonMobil boss Rex Tillerson. It’s a powerful message, to which I would only add one thought: this is only the beginning.

The Climate Show #20: the boys are back (on Tuvalu)

Battling against rural broadband that resembled digital molasses (or the bunker oil being pumped out of the Rena), Gareth returns to NZ and joins Glenn Williams and John Cook to discuss drought in Tuvalu, the El Niño Southern Oscillation (ENSO), floods and sea level falls, ocean cooling (that isn’t), solar towers of power and much, much more…

Butterfly futures flutter by

James Hansen’s latest discussion paper begins and ends with Monarch butterflies. He watches some on his property in Pennsylvania as they prepare to leave for their migration to Mexico and reflects on the prospects for their survival as a species as global warming takes hold. The Monarchs cross Texas on their way south, a difficult path this year over desolate, baked-out territory. Which leads Hansen to a spirited denunciation of “well-oiled Governors and Senators in Texas and Oklahoma” who assert that global warming is a hoax and help business-as-usual CO2 emissions to continue.

He addresses the question of whether the drought and fires in Texas can be attributed to global warming. The media have remained largely silent this year on possible connections between extreme weather events and human-made climate forcing, and Hansen asks whether scientists should be making more effort to draw public attention to the human role in climate anomalies.
