  • See It, Say It:  Climate Change - Washington Post Editorial

    Climate Change News Oct 22, 2017 | 04:15 am

    See It, Say It:  Climate Change - Washington Post Editorial “Nothing More than ash and bones.”  That grim description of how some victims were found underscores the horror of the wildfires that swept through and devastated Northern California.  At least 38 people were killed, including a 14-year-old boy found dead in the driveway of the home he was trying to flee, a 28-year-woman confined to a wheelchair and a couple who recently had celebrated their 75th anniversary.  In addition to the lives lost, approximately 5,700 homes and businesses were destroyed, including entire neighborhoods turned into smoldering ruins. Some 220,000 acres, including prized vineyards, have been scorched, and the danger is not over, as some fires are still burning and officials fear the return of winds could spread more catastrophe.  Fire season is part of life in California, something that residents know and prepare for after the hot, dry summer months.  But the events that began last Sunday have been unprecedented, and so the question that must be confronted is what caused the deadliest week of wildfires in the state’s history. Gov. Jerry Brown (D) pointed the finger at climate change.  “With a warming climate, dry weather, and reducing moisture, these kinds of catastrophes have happened and will continue to happen and we have to be ready to mitigate, and it’s going to cost a lot of money,” he said last week. No single fire can be specifically linked to climate change, and certainly other factors, such as increased development or logging and grazing activities, are involved.  But scientists say there[…]

  • Innovative Satellite Launched for Monitoring Global Methane and Air Quality

    Climate Change News Oct 21, 2017 | 18:33 pm

    Innovative Satellite Launched for Monitoring Global Methane and Air Quality Last Friday, the European Space Agency Sentinel-5p satellite went into orbit above the earth.  Onboard is an imaging spectrometer instrument called TROPOMI, led by SRON (Dutch Space Agency) and KNMI (Royal Netherlands Meteorological Institute) to monitor the amount of methane, ozone and other air quality-related pollutants in the atmosphere. There has been quite a buzz around this unique advancement in space, and the valuable data it will provide on methane, a powerful greenhouse gas that accounts for a quarter of the warming our planet is experiencing today.  Curbing anthropogenic methane emissions is one of the most efficient and economical options available to slow the rate of warming over the next few decades, while efforts continue to reduce CO2 emissions worldwide. Detecting methane from spaceMethane sources include both natural and manmade emissions from livestock, agriculture, oil & gas operations, and landfills.  These sources are distributed around the world and vary widely at local, regional and temporal scales—which makes it challenging to quantify emissions from diverse sources. This is where satellites come into play.  They bring together the unique capability of continuously monitoring the entire planet, measuring critical geophysical variables, and mapping change by collecting long-term datasets. The TROPOMI satellite sensor brings significant advances in the monitoring of air pollution in terms of better resolving methane, and other major pollutants affecting air quality (e.g. NO2, SO2, formaldehyde, aerosols).  For instance, data from TROPOMI will be available at 7 km x 7 km grids around the world, on a daily basis—which has never[…]

  • The Connecticut Green Bank:  Innovation in Finance Sparks New Model for Public/Private Investment in Clean Energy

    Climate Change News Oct 21, 2017 | 06:35 am

    The Connecticut Green Bank:  Innovation in Finance Sparks New Model for Public/Private Investment in Clean Energy The Harvard Kennedy School’s Ash Center for Democratic Governance and Innovation announced in July that the Connecticut Green Bank had won this year’s Innovations in American Government Award.  The Ash Center award recognizes excellence and creativity across a wide range of government initiatives, from technology and public health programs to conservation and education.  That Connecticut’s pioneering clean energy financing model won this prestigious award, selected from among thousands of entries, speaks to the important role of states in accelerating the renewable energy transition. Connecticut first established the Green Bank in 2011 through Public Act 11-80 as a key part of the state’s strategy for achieving its energy and climate goals.  The main objective was to have cleaner, cheaper, more reliable sources of energy while also creating jobs and spurring local economic development.  Leveraging private investment dollars with limited public funds is at the heart of the green bank’s operation. Since its inception, the Connecticut Green Bank has attracted over $6 of private capital for every $1 of public funds committed.  Overall, the Connecticut Green Bank has achieved nearly $1.1 billion in clean energy investment across the state.  This investment has supported almost 25,000 projects and more than 230 megawatts of clean energy, resulting in greenhouse gas emissions reduction of 3.7 million tons.  Over 13,000 jobs have been created, translating to an estimated 7.5 to 20 percent of total job creation in Connecticut, and clean energy prices have declined by about 20 to 30 percent. Among the Green Bank’s most successful[…]

  • Delaware Researchers Discover How to Cut Offshore Wind Construction Costs by $1.6B

    Climate Change News Oct 21, 2017 | 06:35 am

    Delaware Researchers Discover How to Cut Offshore Wind Construction Costs by $1.6B Working closely with industry partners, University of Delaware researchers have developed a new method for constructing offshore wind farms and proven that it is cheaper, faster, and could make possible offshore wind deployment at a scale and pace able to keep up with the region’s scheduled retirements of nuclear and coal-fired power plants. The researchers calculated that their innovative process will cost up to $1.6 billion less per project than conventional approaches and take half the construction time. “In planning for offshore wind power, the big question is how we generate electricity cost-competitively, and at a scale that is both a relevant replacement for aging power plants and also applicable to climate change,” said the project’s principal investigator, Willett Kempton, professor in the College of Earth, Ocean, and Environment (CEOE).  “We’re the first people who have shown the engineering details, step-by-step, how to achieve that.” FindingsThe key insight that allowed Kempton’s team to make such considerable optimizations in cost and deployment speed was that the entire structure, from seafloor mounting to the top of the turbine, can be assembled in one piece in port, moved as a unit, and in one step placed into the sea floor.  It may seem like a simple idea, but it was by no means obvious that it would work with existing equipment until completing the detailed engineering and cost analysis. The reference design used 10-megawatt turbines with support structures, together standing twice as tall as the Statue of Liberty and weighing 2500 metric tons,[…]

  • CliFi – A New Way to Talk About Climate Change - by John Abraham

    Climate Change News Oct 21, 2017 | 05:46 am

    CliFi – A New Way to Talk About Climate Change - by John Abraham Cli-Fi refers to “climate fiction;” it is a term coined by journalist Dan Bloom.  These are fictional books that somehow or someway bring real climate change science to the reader.  What is really interesting is that Cli-Fi books often present real science in a credible way.  They become fun teaching tools.  There are some really well known authors such as Paolo Bacigalupi and Margaret Atwood among others.  A list of other candidate Cli-Fi novels was provided by Sarah Holding in the Guardian. What makes a Cli-Fi novel good?  Well in my opinion, it has to have some real science in it.  And it has to get the science right.  Second, it has to be fun to read.  When done correctly, Cli-Fi can connect people to their world; it can help us understand what future climate may be like, or what current climate effects are. As I write this, we are getting a steady stream of stories out of Puerto Rico the island was devastated by Hurricane Maria.  It is hard to imagine the devastation, what life is like without electricity, food, or water.  What is life like on an island of 3 million people, each fending for themselves, just trying to survive. Another thing that is hard to imagine is the future.  What will the world be like decades from now when Earth temperatures have continued to rise?  What will agriculture be like?  What will coastal communities be like?  What will international relations and armed conflict be like? It is[…]

  • Daimler Shows Off New Self-Driving Snow Removal Trucks

    Climate Change News Oct 21, 2017 | 04:14 am

    Daimler Shows Off New Self-Driving Snow Removal Trucks Following its successful demonstration of the Highway Pilot and Highway Pilot Connect systems (earlier post)—the latter making truck platooning possible—Daimler has demonstrated automated snow removal operations on the site of the former Pferdsfeld airbase.  This application of autonomous commercial vehicle operation was based on a specific customer requirement. Under the project name “Automated Airfield Ground Maintenance” (AAGM), four Mercedes-Benz Arocs tractor units demonstrated automated airfield clearing in a remote-controlled convoy.  The benefits are obvious:  Airfield clearances are hard to predict and thus difficult to plan, especially in winter.  This makes snow removal units operated with pinpoint precision by a single vehicle operator to remove snow from runways especially crucial when extreme weather strikes without warning during the winter months, and they require no additional vehicle and staff scheduling.

  • 4 Questions About Climate Change and the California Fires

    Climate Change News Oct 20, 2017 | 02:57 am

    4 Questions About Climate Change and the California Fires Rising temperatures can make the U.S. West dangerously combustible.  We saw it this year in California wine country. The deadly fires that swept through California's wine country made one of the state's most destructive fire seasons on record even worse.  As global temperatures continue to rise, scientists say the risk of extreme fire seasons across the West is rising, too. Wildfires are hugely complex events, complicated by human activity, including rampant development and decades of fire suppression strategies that left too much dry timber and underbrush for fires to burn.   Add the effects of climate change to the mix, and California's already fire-prone landscape grows increasingly combustible. What's the link between fires & climate change?An increasing body of research finds that the hot and dry conditions that created the California drought were brought on in part by human-caused warming.   Higher temperatures pull moisture out of soil and vegetation, leaving parched landscapes that can go up in flames with the slightest spark from a downed utility wire, backfiring car or embers from a campfire. California's average temperature has risen about 2 degrees Fahrenheit during the second half of the 20th century.  Altogether this has led to more "fuel aridity"—drier tree canopies, grasses and brush that can burn. "There's a clear climate signal in these fires because of the drought conditions connected to climate change," said Daniel Swain, a climate scientist at UCLA. Hot, Dry Years Becoming More Common in California"As long as there's fuel to burn, your chances of having large[…]
