climate change

1. The California Drought Becomes an Emergency
California’s multi-year drought grew dire enough in 2014 to prompt Governor Jerry Brown to declare a drought emergency in January. By the end of the year, California had experienced the driest and hottest 36 months in its 119-year instrumental record. Some researchers described the drought as 1) the worst in over 1200 years and 2) evidence of rising temperatures globally as climate changes accelerate. As of mid-January, the drought is continuing.
As the California and western…
pgleick | January 13, 2015The California drought continues.
While we do not know yet what the rest of the wet season will bring – and while we hope for the major storms needed to recharge our rivers, groundwater and reservoirs – it seems increasingly likely that California will not see enough precipitation to get out of the very deep deficit that three years of drought (so far) have produced.
There is, however, some misleading and confusing information out there. Some are already arguing that California’s rainfall is nearly back to normal or that because there may have been more serious droughts in the past we needn’t…
kkrisberg | December 17, 2014When compared with gasoline-powered cars, vehicles fueled with electricity from renewable sources could cut air pollution-related deaths by 70 percent, according to a new study, which noted that air pollution is the country’s greatest environmental health threat.
Published this week in the Proceedings of the National Academy of Sciences, the study’s researchers examined the impact of various vehicle energy sources on the concentrations of two types of air pollutants known to affect human health: particulate matter and ground-level ozone. Previous research has found that air pollution causes…
pgleick | December 8, 2014Over the past three years (and indeed, for 10 of the past 14 years) California has experienced a particularly deep drought. How bad is the drought? Is it the worst in the instrumental record? The worst in over a century? The worst in 1200 years? The worst “ever”? And why has it been so bad?
There is no single definition of “drought.” Drought, most simply defined, is the mismatch between (1) the amounts of water nature provides and (2) the amounts of water that humans and the environment demand. As the National Drought Mitigation Center puts it:
“In the most general sense, drought originates…
dr. dolittle | November 5, 2014 Siberian sturgeon in captivity
Drs. Thomas Eliot Haworth and Holly Shiels (University of Manchester) teamed up with Drs. Jaakko Haverinen and Matti Vornanen (University of Eastern Finland) to explore how electrical signaling in the hearts of fish have evolved by comparing Teleost fish with sturgeons. Their findings were published this month in the American Journal of Physiology - Regulatory, Integrative and Comparative Physiology.
According to the study authors, there are currently approximately 27,000 species of ray-finned fishes which make up 99% of all fishes existing today. Teleost…
pgleick | October 18, 2014In a new study just published by the journal Sustainability Science (Springer), analysis from the Pacific Institute (with lead author Dr. Juliet Christian-Smith, now at the Union of Concerned Scientists) shows that many of the fundamental responses of California water users to severe drought actually make the state’s overall water conditions worse – that in the end, many of these actions are “maladaptations.”
Water is a complex resource; and water problems are an equally complex mix of natural resource, technology, social, economic, and political conditions. When water is limited, such as in…
gregladen | October 14, 2014This is an endorsement by Climate Hawks Vote, which I support.
Climate Hawks Vote is delighted to endorse in four California Congressional elections, joining our prior endorsement of Scott Peters (CA-52, San Diego). In order purely alphabetical, they're Lois Capps, Heidi Hall, Mike Honda, and Ted Lieu.
Lois Capps (CA-24, Santa Barbara) has earned our endorsement by being a tireless advocate for action on climate. She has the second-highest score among all Democrats in the House of Representatives on our scorecard measuring leadership. Her climate resilience ideas, in particular, have been…
gregladen | October 12, 2014This is an endorsement by Climate Hawks Vote, which I support.
Climate Hawks Vote is delighted to endorse Scott Peters in California’s 52d Congressional District of San Diego for his strong climate leadership and for taking first place in our August 2014 survey. And his approach just may break partisan gridlock in Congress.
Scott Peters has a reputation as a problem solver. Climate hawks tend to fly on the left wing of the Democratic Party, but Peters has demonstrated that climate transcends political partisanship. He’s spoken out onsuper-pollutants, national security, and resiliency, all…

Wednesday was the last day of the meeting that culminated in a closing banquet with an awards session to honor students who had exceptional presentations. What an impressive group of young comparative physiologists! The plenary lecture was given by Dr. Steven Chown (Monash Univ, Australia). He spoke about climate change forecasts and continuing environmental changes and how important it is to understand how animals adapt to changing conditions in order to make…

Climate Hawks Vote announces endorsements of two Michigan Democrats: Paul Clements for Congress in Michigan’s Sixth District, and Gary Peters for Senate, because the Koch brothers and Big Oil need to stop using Michigan’s shores as a dumping ground for their pollution and Michigan’s politicians for their agenda.
Paul Clements is challenging none other than Fred Upton, chair of the House Energy & Commerce Committee - these days, the House Big Oil Lackey Committee. As the face of Big Oil, Upton was named the number one enemy of…

Tuesday was no less exciting than Monday!
Here are some highlights:
I thoroughly enjoyed a session called "Overcoming a Major Physiological Barrier: Adaptation from Saline to Freshwater Habitats" which highlighted the need for several species to shift how they regulate ion balance when they migrate between fresh water (ion absorption from the water) and salt water (ion secretion to the water).
Clements K, Bojarski L, Johnson K, McMillan S, White L, Angert E (Univ…

We’re working our way through scoring Senate Democrats on climate leadership, using the same lodestar that we’ve used on House Democrats: who’s leading on climate by engaging the public? It’s slow going - results might not be final until mid-October or later. However, given the intense interest in certain races, we’re releasing a few scores early. Jeanne Shaheen has earned a high score, and thus our endorsement, for her deep commitment to energy efficiency.
Jeanne Shaheen, New Hampshire Senator, has earned a very high score on our…

We’re endorsing climate hawk Shenna Bellows to be the next Senator from Maine because business as usual is no longer good enough in the face of a local and worldwide crisis. Long-time incumbent Susan Collins admits the existence of a problem, to her credit; but far from proposing credible solutions, her actions range from policy homeopathy to delay to active hindrance.
While working on our sophisticated scorecard measuring leadership - not just votes - on climate for Senate Democrats, we are also tracking four Senate Republicans…

gregladen | September 28, 2014The Arctic Sea is covered with ice during the winter, and some of it melts off every summer. Over recent years the amount of melt has been increasing. This is the time of year we may want to look at Arctic Sea ice because by late September it has reached its annual minimum and is starting to reform.
Looking at JUST surface area, which is one indicator of how warm the Arctic has become with Global Warming, we can see (above) that this years march of melting has been extreme, hugging the two standard deviation limit for all of the data from 1979 to 2010 (almost the present).
Here you can…
pgleick | September 26, 2014In the 20th century, society was either ignorant of, or ignored, the consequences of bad water management. The goal was economic development at all costs. Over the past few decades, we've learned about the ecological and social implications of the misuse of water, and some efforts have been made to protect natural ecosystems, restore a modicum of flows, bring local communities into the discussion about water policy and infrastructure. These are steps in the right direction.
But sometimes our failures have been monumental -- and uncorrected.
Perhaps the best, or worst, example, is the complete…

gregladen | September 11, 2014Ken Cuccinelli posted a highly offensive cartoon on his facebook page in which Hillary Clinton is depicted in a position where she is about to be beheaded by a caricature of a Middle Eastern terrorist. That was posted on the even of the anniversary of 9/11.
You will know of Ken Cuccinelli as the anit-climate-science activist, who was involved in the fake scandal known as "Climategate."
Lowkell at Blue Virginia writes:
...this is appalling even by Ken Cuccinelli standards. First off, he links to a climate science "skeptic" website. Then, he channels Rand Paul's insane criticism of Hillary…
gregladen | July 18, 2014Governor Mark Dayton has called for the elimination of coal as a source of energy in Minnesota. Doing so is, clearly, essential. Having a governor call for it is a new thing; we are only seeing this sort of policy being developed recently.
From MPR News, Dayton said to a group of energy policy ad business leaders:
"Tell us what a timeline would look like, what has to happen for that timeline to be met and what kind of incentives or inducements do we need to provide to make that happen," ...
Dayton's comments came during the state's first-ever Clean Energy Economy Summit. He said…
illconsidered | July 15, 2014Aside from the climate blogosphere, Paul Krugman's "Conscience of a Liberal" is my most regular blog visit. He does not usually have a lot to say on climate change (which is mildly disappointing) and I have seen only very shallow and casual dismissals of the, to me compelling, notion that perpetual growth as a requirement for economic prosperity is problematic (which is very disappointing). It is however, usually very interesting and I have learned a lot about economics, something very apropos given the ongoing global crisis. I do enjoy the political snark as well, as long as it is reality…
