Are farmers responding to the right signals? - WWF Climate Prep Blog feature

I've been remiss in updating this little blog o' mine lately, but I do have something to show for it-- a guest-author article on the WWF Climate Prep blog! I decided to write about some recent research done in California and Europe on the choices farmers are making around climate change adaptation. Read my article here:

Farmland in Flux - July 8, 2014 - WWF Climate Prep blog

I promise my readers I will get back in the groove with this blog now that the summer doldrums are upon us.

Stanford Researcher: Windmills Slow Hurricanes

This blows my mind, no pun intended.

From the March 1, 2014, Economist: Hurricane protection: The windmills of your mind: A madcap idea to protect America's coasts from storms

Here's a hyperlinked Feb. 26 Stanford newsletter item about Dr. Mark Jacobson's computer simulations of wind farms lessening hurricane strength:  Offshore wind farms could tame hurricanes before they reach land, Stanford-led study says

Read Dr. Jacobson's paper (with C. Archer and W. Kempton) as published in Nature Climate Change (online Feb. 26, 2014):

Taming Hurricanes With Arrays of Offshore Wind Turbines

 I think I'm going to have to read all of these articles several times to wrap my brain around this.

Climate Readiness Institute launch at UC Berkeley today

I am tweeting as @stripeygirlcat at the launch of the Climate Readiness Institute at the Brower Center at UC Berkeley today-- follow me! (I only use that account for climate change-related posts, no live-tweeting the Oscars will ever occur there.)

There is quite a brain trust here today. Inspiring.

It was Peaceful on Zero Allocation Day - California Water Law Symposium Report-Back

I've been in and out of one climate change-related stakeholder meeting, conference, workshop, symposium, training or another since mid-January, it seems-- I haven't had time to catch my breath and update this blog. There's been much afoot, with the new iteration of the California Climate Adaptation Strategy out in draft format for comment,and the official onset of drought in California Jan. 17, and the related gnashing of teeth and rending of clothes. Not to make light of it, but the fact that California has a water problem is not very new news. We haven't had serious precip here since December 2012. In fact, one scientist says it may be the driest water year in 500 years (per a Jan. 21 article based on an interview with paleoclimatologist B. Lynn Ingram at UC Berkeley).

Yesterday was a highlight of the recent onslaught of climate change-related gatherings-- the California Water Law Symposium

Some notes:

ZERO ALLOCATION DAY, a Friday, was a quiet day. Fish and farms have nothing to fight over. Finally these interests have something (no water) in common.

John Leshy: Looking back, California used to have 150 yr-long droughts; it was settled in an unusually wet period; all our distribution systems were designed for a larger volume of water than we can expect in the future.

Forrest Melton: NASA Ames is using satellites (2 landsats, 2 MODIS) and ground data (CIMIS -- the California Irrigation Management Information System) to calculate how much to irrigate given evapotranspiration-- super efficient use of water!

Jay Lund: Everyone thinks the solution to drought is to build reservoirs. But it's not Field of Dreams-- build a basin and it will fill with water-- we are losing snowmelt as a source, we shouldn't invest in new infrastructure that is dependent on historical conditions. Repurpose old, smaller reservoirs? Manage groundwater better!

Cliff Lee: The Endangered Species Act (ESA) is potentially going to be rendered irrelevant by climate change (which will make many historic salmon streams too shallow/warm for spawning--> some populations are doomed, ESA can't save them) 

Lester Snow: GROUNDWATER GROUNDWATER GROUNDWATER; innovation; diversification; learn to manage resources as well as we manage crises (reacting to symptoms, not problem); need to reach out to find new leadership among Latinos, Millennials-- demographic shift is salient to water planning

Desalination-- Carlsbad Project-- desal is either a totally reasonable, do-able thing or the devil's work, bound to poison the ocean at brine discharge site and tie ratepayers to high-priced, energy-intensive water

Fresh water flow into the San Francisco Bay Delta is either critical to estuary health or not, apparently evidence is disputed; a good source on the Delta is Aquafornia

That's all, pray for rain

News from the Human Rights/Climate Change Nexus: +Heat = +Native Cultural Losses, +Conflict

The Dec. 18, 2013, Al-Jazeera article "How climate change destroys human rights" by Jon Letman offers an interesting sampler plate of five recent studies and organizing efforts to illustrate the human rights/climate change nexus.


The Letman article was brought to my attention by a friend and former colleague, now at Tebtebba, because another friend and former colleague, Rodion Syulandziga from the Russian indigenous rights network RAIPON, contributed to it. (Click here for info on RAIPON in English, from the Arctic Council's website.)

Rodion points out to Letman that "[i]ncreasingly unpredictable weather and unreliable sea ice directly impacts animal migration, which affects subsistence hunting for traditional food sources like reindeer and sea mammals. Warmer temperatures ... also hasten the introduction of plant and animal diseases as southern species of fish and birds move north." And, "[i]n addition to a warming Arctic, Russia’s indigenous peoples also face the rush to exploit vast energy and mineral resources. Oil, gas, coal, nickel, iron ore, platinum and other minerals draw multi-national corporations to Russia’s most remote regions where highly restricted access makes monitoring health and safety practices, damage and pollution mitigation and other conditions difficult or impossible."

Rodion also touches on how RAIPON is being subjected to increasing threats from the Russian government. In 2012-2013 this involved using technicalities of the law to suspend the group's activities during a critical period of time (when a national RAIPON gathering was supposed to happen), ordering the arrest of a staff member on specious grounds when he was abroad at a conference, and using political pressure to increase the influence of Kremlin-friendly indigenous representatives in the organization. Indigenous communities whose cultures are predicated on the existence of permafrost and sea ice are existentially threatened by climate change, and in Russia, also by the government's repression of civil society.


I see another familiar reference in this article-- a link to a study of how heat correlates with aggression in Kenya, led by Solomon Hsiang, now a professor at UC Berkeley's Goldman School of Public Policy, my alma mater. He did the study with Ted Miguel of the UC Berkeley-based Center for Effective Global Action (CEGA), which analyzes the impact of development projects, and Marshall Burke, also at UC Berkeley (in Ag and Resource Economics). The study supports the idea demonstrated in other studies "that climatic events which produce temporary warming are associated with a temporary increase in violent intergroup conflict..." (p. 2). Sol Hsiang has a fascinating body of work on the social implications of climate threats.
Some highlights of Sol's work:

Losing your glacier? Make your own!

This is amazing. Do-it-yourself glaciers: The iceman cometh: If climate change takes your local glacier away, why not build another? (July 13, 2013, the Economist)

This doesn't solve every problem related to the loss of the glaciers, but it gets at one aspect that hurts a vulnerable population-- farmers who depend on snowmelt to irrigate crops in high altitude (short-growing-season) climates.

"[S]ome farms are better-off now than they used to be in the days before the natural glaciers vanished."

Hats off.

Even hardy blue oaks have their limits- KQED coverage of Bay Area climate change

Yesterday KQED's Lauren Sommer aired this 5 min. piece about SF Bay Area climate change impacts, focusing on the plight of the blue oaks of Mount Hamilton and other California live oak species featuring the work of some of my colleague adaptation experts at the Nature Conservancy (TNC), UC Berkeley, and the Pepperwood Preserve in Sonoma County. Follow that link for maps and other links.

"It could be these oaks are already living at their limit, says [TNC's] Sasha Gennet."

Talking to David Ackerly (UCB) and Pepperwood's Lisa Micheli, the reporter comments: "Think of it as an acorn-by-acorn race with climate change."
