Can the US political system handle climate change?

It has been said by experts in the climate change field that the more time that passes, the more difficult it will be to make the necessary changes to help our planet.  Are we late in our response to climate change?

Bill McKibben, American environmentalist, discusses the relationship between climate change and the US political system.

This is a debate between humans and physics.  Unfortunately physics is not interested in following the same timetables as humans.  Whether or not gas prices rise, or the coal industry undergoes changes, or pricing carbon will slow the pace of development in China, or agribusiness is less profitable, physics will continue on it’s way.

Physics’ job is to take the carbon dioxide we produce and translate it to heat.  That means melting ice, rising oceans, and gathering storms.  Again, the more time that passes, the harder it will be to handle these changes in our environment.

For example, if we postponed healthcare reform for a decade, the outcome would be terrible.  There would be more suffering in those 10 years. However, when we returned to the problem, it would be about he same size. With climate change, if we don’t act now, the problems will be greater and more difficult to fix.  If you do not understand the distinction between these problems, you do not understand climate change.   It seems those in the government don’t necessarily fully understand climate change.

The response to climate change from those in the government has been slow for a few reasons.  There is resistance in the system to implement necessary changes.  The resistance has been expressed in a number of ways such as President Obama using spies at the NSA to kill global agreements on climate change, the bipartisan popularity of climate change denial in Congress, and the public relations industry and the media.  Even though there has been essentially indisputable scientific evidence, some still are in denial, or disbelief.

The resistance exists in many groups, based on their perceived interests. There are extremely powerful corporations who want to maintain their wealth from fossil fuels and other related industries.  There are individuals who rely on their jobs for security and unfortunately their jobs exist because of the fossil fuel industries. There are people who are simply afraid of economic chaos.  What if that leads to loss of the comforts they are used to?  There are some politicians whose fortunes depend on the money from the fossil fuel industry.  Unfortunately these same politicians are the ones crucial to instigate the changes needed to address climate change.

Politicians are falling short of addressing their problems.

What the World Could be

A recent poll showed that of the top 18 issues that Americans care most about, 10 would be fixed with Public Banks and monetary reform.  Unfortunately climate change and ocean acidification were not even on the list.

Good news is that after talking with dozens of people across the country who work towards Public Banks and monetary system reform, all of them want to use the abundant funds that would be released to the public to build environmentally safe infrastructure.   We could reduce traffic jams, there could be comfortable electric rail systems, solar farms could create abundant clean energy.  Anything is possible.

Improving Solar Panel Output with Optimizers

Solar panels currently cannot communicate, cannot adjust to environmental circumstances, and do not have automatic shutdown capabilities. However, solar panels continue to get more efficient.  Most of the newer solar panels are equipped with optimizers, either built in or separately attached.  Microinverters provide the same basic benefits at similar costs; however, optimizers operate on the DC side are always connected to a central or string inverter.

Optimizers, also referred to as power electronics, provide three basic functions:

  1. They optimize the output of each panel by adjusting the current and voltage generated by each panel. If there is a panel operating at a low current, the optimizer can lower the voltage, which will increase the current and prevent the panel from affecting the current of other panels.
  2. Optimizers are made so that the installer or system owner can see the performance of each individual panel.
  3. Some of the newer optimizers provide code-required automatic DC shutdown capabilities to prevent arcing and fires.

Optimizers may have gotten a slow start, as with many new solar technologies.  New solar technologies tend to have higher initial costs and unproven benefits.  Yet as production increases, prices decrease, operating capabilities improve, and more installers use optimizers for residential and commercial projects.  A big step was when the panel manufacturers began to integrate optimizers into the junction boxes.  This led to reduction of cost of parts and installer labor.

UN Report on Climate Change

A recent study determined that humans are causing irreversible damage to the planet from burning fossil fuels.  Unfortunately not everyone is thoroughly convinced that there is a high risk of widespread harm from rising global temperatures.  This risk could explain recent floods, droughts, and extinction of species and ocean acidification.  If carbon emissions continue to increase, these phenomenons will increase in frequency.  If humans can cut emissions quickly, we may be able to avoid such occurrences and maintain the health of our planet.

“We must act quickly and decisively if we want to avoid increasingly disruptive outcomes, “UN Secretary-General Ban Ki- moon told reporters in Copenhagen. He continued, “If we continue business as-usual, our opportunity to keep temperature rises below the target of 2 degrees Celsius will slip away within the next decades.”

This report of the study is intended to guide policy makers around the world to take the climate change into account when writing laws and regulations.  We need to protect our nation.  Currently 195 nations are working on an international agreement to decrease emission output.  The goal is to reach an agreement by December of 2015.   Another goal is to get to zero emissions by the end of the century, the estimated target number that could keep global warming below dangerous levels.  Ottmar Edenhofer, chief economist at Potsdam Institute for Climate Impact Research Institute, believes that “this requires a huge transformation, but it doesn’t mean we have to sacrifice economic growth.”

Five years of unpaid work by scientists resulted in this report. These scientists have filtered through research in all areas of global warming and comprised one document summarizing the most important findings.  The panel previously won a Nobel prize for their work carried out in 2007.   Now they are even more certain of the dangers of global warming.

“Continue emission of greenhouse gases will cause further warming and long-lasting changes in all components of climate system, increasing the likelihood of severe, pervasive and irreversible impacts for people and ecosystems.  Limiting climate change would require substantial and sustained reductions in greenhouse-gas emissions which, together with adaptation, can limit climate change risks,” it says in the report.

Delegates from 120 nations went through the report in effort to make sure it would be easy to understand.  Sometimes the words in scientific findings can be a bit difficult to interpret.  Countries have been commenting on a draft of the text.  The study aimed to link three earlier reports by the panel.

Youba Sokona, one of the authors of the report said, “It is technically feasible to transition to a low-carbon economy.  What is lacking is appropriate policies and institutions.  The longer we wait to take action, the more it will cost to adapt and mitigate climate change.”

Certain major companies such as Exxon Mobil and Royal Dutch Shell Pic claim they do not see a danger of their assets loosing a need in response to regulations aimed to prevent climate change.  Emissions-reduction measures would cut out 0.06% points off annual economic growth this century. Reduced climate change would also increase human health and standard of living.  Some other findings the panel came up with include:

  • Manmade greenhouse gas emissions have pushed atmospheric concentrations of carbon dioxide, methane and nitrous oxide to levels ‘unprecedented’ in the past 800,000 years.
  • In order to cap the level of warming at 2 degrees Celsius since the 1800 requires no more than 2,900 billion tons of carbon dioxide.  We have already emitted two thirds of that as of 2011.
  • The global average sea level has risen by 19 centimeters since 1901.  It is likely to continue to rise.
  • The global average temperature has risen by 0.85 of a degree Celsius since 1880.  It is predicted to gain 0.3 degrees to 4.8 degrees this century.

As climate change accelerates, we experience economic damage as well.  Increase in temperature above pre-industrial temperatures cuts economic output.  It’s predicted that an increase of 2.5 degrees would cut economic output by about 2%.

The internationally agreed target is a global temperature raise of 2 degrees. Future scenarios with this temperature raise indicate there would be a quadruple of zero-carbon technologies in energy supply. Such energy supplies include wind and solar power, nuclear reactors and fossil fuels equipped with carbon capture.

Samantha Smith, leader of the climate program at environmental group WWF, claims cost reductions and performance improvements in renewables enable governments to decarbonize their economies at a price that is lower than ever.

Secretary of State, John Kerry, said the report sends a strong, important message.  More debate utilizes more resources and only prolongs us fixing anything.  “Those who choose to ignore or dispute the science so clearly laid out in this report do so at great risk for all of us and for our kids and grandkids,” John Kerry remarked in an e-mail.

TransCanada’s Keystone XL pipeline

The proposed route of TransCanada’s Keystone XL pipeline crosses directly through Great Sioux Nation (Oceti Sakowin) Treaty lands as defined by both the 1851 and 1868 Fort Laramie Treaties and within the current exterior boundaries of the Rosebud Sioux Reservation and Cheyenne River Sioux Reservation.

Tribal president Scott articulated the position of his people quite clearly.

“The House has now signed our death warrants and the death warrants of our children and grandchildren,” Scott said. “We are outraged at the lack of intergovernmental cooperation. We are a sovereign nation and we are not being treated as such. We will close our reservation borders to Keystone XL. Authorizing Keystone XL is an act of war against our people,” he said

“The Lakota people have always been stewards of this land. We feel it is imperative that we provide safe and responsible alternative energy resources not only to tribal members but to non-tribal members as well. We need to stop focusing and investing in risky fossil fuel projects like TransCanada’s Keystone XL pipeline. We need to start remembering that the earth is our mother and stop polluting her and start taking steps to preserve the land, water, and our grandchildren’s future.”
