Why California Thirsts for Rain and the East Coast gets Soaked

rain_378x235_1If you think the weather’s acting strange, you’re correct. Extreme weather in the United States is trending upward, and human-caused climate change has already been blamed for much of it – most recently in connection with the California drought.

But along with extreme weather we’re also getting extreme contrasts. What on Earth is going on when New York gets endless rain and San Francisco none, and when one part of the country is freezing while another suffers under record heat?

You guessed it, rising temperatures have something to do with it – and here’s how.

Rain patterns are changing

In the Northeast, the combination of more moisture in the atmosphere from a warmer world and changes in circulation patterns are bringing more rain. In the Southwest, meanwhile, rainfall is suppressed by a northward expansion of high pressure in the subtropics. Read More »

How Scientists Linked the California Drought to Climate Change

calidrought_378x235_2California has officially entered its fourth consecutive year of drought, and is trapped in its worst water shortage situation ever.

Because we know that human-caused climate change can trigger and exacerbate drought conditions, media, public officials, California residents, and scientists have all been wondering for years if rising global temperatures likely caused or contributed to the current drought in California.

The short answer: Yes, they did.

Weather won’t cooperate

Scientists have suspected for some time now that a certain meteorological condition lies behind the long-lasting California drought. The persistence of a stubborn high-pressure system off the coast has been preventing storm systems from reaching California and instead deflecting them to Alaska and elsewhere. Read More »

Strength in Numbers: Linked California-Quebec Market Benefits Environment and Economy

KHK pictureBigger is not always better, but a recent cap-and-trade auction in Quebec gave us one example of why it may be the case for a combined California and Quebec carbon market.

The linkage of Quebec and California’s markets has been watched by many around the world, and the start of joint auctions in November 2014 is the final step in full linkage. Last month, however, both jurisdictions were busy conducting their last solo auctions. While the results of the California-only auction were as anticipated, the Quebec-only auction yielded both expected and less expected results.

What was not a surprise was that not all (83%) allowances offered for sale were purchased. Unlike in the California program, Quebec entities do not have to surrender any allowances this coming November. With their first deadline not until November 2015, Quebec entities have been understandably slow to enter and be active in the market. Another positive and not so surprising takeaway from Quebec’s last auction is high demand for 2017 allowances, a strong sign that Quebec companies are confident in this market’s future health.

More surprising to observers in Quebec’s recent auction, however, was that a higher percentage of 2017 vintage allowances sold than 2014 vintage allowances. Current 2014 vintage allowances can be used for compliance at any time, while 2017 vintage allowances can only be used starting in 2017. This longer useful life should make 2014 allowances more valuable and thus in higher demand, but this did not appear to be the case in the recent auction. Read More »

California Clean Energy Bill Could Open Door for Homeowners and Small Businesses

Governor Brown has the opportunity to make energy-saving upgrades possible for families and small business owners by signing Assembly Bill 1883 (Nancy Skinner- Berkeley). This bill would significantly lower the cost of Property Assessed Clean Energy (PACE), a tool which enables property owners to take advantage of energy efficiency and rooftop solar PV for their homes or buildings with no money down, allowing them to pay off the investment over time through their property tax bill.

AB 1883 would streamline the PACE process and drive down the fixed transactional costs associated with commercial projects. Lowering these transaction costs is especially important for small businesses because high transaction costs can reduce the economic viability of the smaller energy upgrades that small business typically need. AB 1883 also incorporates new options for financing rooftop solar PV through PACE, which will enable a greater number of homeowners and small businesses to qualify for cost-saving solar PV contracts.

As California’s Legislative Session Ends, Key Environmental Protections Begin

A quick look back at California’s 2014 legislative agenda, which closed in the early morning hours of August 30th, shows it certainly was one for the record books. California took up major efforts to cut climate pollution and portion out billions in new investments, modernize the electric grid, and take on other not-so-small issues such as phasing out plastic bags. This activity happened while California led the nation in a remarkable economic rebound, continued to deal with an epic drought, and combatted the worst air quality in the U.S.

Among the many environmental issues in the spotlight this year, climate change, air quality, clean energy, water, and waste lead the pack.

Implementing a climate protection framework worthy of acclaim

On climate, lawmakers turned a corner by affirming the state’s commitment to AB 32 and green-lighting a new era of pollution reducing investments from the state’s world-class cap-and-trade regulation. Keeping transportation fuels within cap and trade starting January 2015 remained a main focus, with lawmakers facing and rebuffing numerous attempts by regulated industries and other legislators to undermine and delay the state’s landmark program. Throughout the session, lawmakers remained strong, demonstrating a commitment to the state’s growing clean economy and the need to capture the huge savings in health and fuel costs AB 32 will provide.

Pollute less, employ more…

jobsaheadBy: Sean Wright, EDF senior analyst, natural gas program, and James Frank, EDF graduate intern

Cleaner air, more American jobs: that’s a potential reality for the U.S. if it acts to curb emissions of methane, a powerful greenhouse gas emitted from oil and gas systems around the country. It’s a significant opportunity, and it’s one California Congresswoman Linda Sánchez encountered first-hand when she toured a Cerritos manufacturing plant last week.

“I am convinced that we can reduce the risks from climate change with American-made products and create more jobs in California while we’re doing it,” the Congresswoman said during her visit.

The energy industry likes to argue that methane controls are expensive, unnecessary, and bad for business, but more and more evidence is surfacing that’s not the case. In actuality, limiting methane emissions from oil and gas operations represents a significant economic opportunity. The manufacturing plant, which produces sealing technologies that help control methane leaks, employs 44 people in California’s 38th district. As a subsidiary of the larger US energy services company John Crane, it is poised to grow even larger if the need for more methane mitigation technologies increases. Read More »
