Current CO2 Level in the Atmosphere


2015 Likely to Be Hottest Year Ever Recorded

As reported in the Science section of the Oct. 21, 2015 New York Times, 2015 is likely to be a record-breaker for global warming.

Global temperatures are running far above last year’s record-setting level, all but guaranteeing that 2015 will be the hottest year in the historical record — and undermining political claims that global warming had somehow stopped.

The National Oceanic and Atmospheric Administration, the American agency that tracks worldwide temperatures, announced Wednesday that last month had been the hottest September on record, and in fact took the biggest leap above the previous September that any month has displayed since 1880, when tracking began at a global scale. The agency also announced that the January-to-September period had been the hottest such span on the books.

For much of the past decade, people who question established climate science have been claiming that global warming had stopped. Their argument depended on picking a particular base year — almost always 1998, the final year of the last strong El Niño — as their starting point.

But mainstream climate scientists said that was a statistically invalid cherry-picking of the data, and their analysis of the entire record showed that global warming never stopped — at most, the rise of surface temperatures slowed somewhat, even as the oceans continued to warm at a brisk pace.

The record-setting warmth of 2014 and 2015 has undermined the idea that the problem of greenhouse emissions had somehow solved itself, though some Washington politicians continue to repeat the claims. Climate scientists have not wavered in their view that the long-term temperature increase poses profound risks and that emissions must be brought under control.

The question is, will world leaders take action before it’s too late, or will they pass the problem on to future generations? Keep your eyes on the Paris global climate conference in early December.

Why is the color of LED lighting so important?

The latest generation of LED (light emitting diode) exterior lighting is significantly more energy efficient than even high pressure sodium fixtures (the orange-tinted street lights that are commonly used).  And what’s made the recent use of LED lights take off is the dramatic decline in prices for all types of LED fixtures. However, especially when considering exterior lighting like parking lot or roadway lights, careful consideration of the color hue of that lighting is important. The following is excerpted from the site of the non-profit International Dark-Sky Association (IDA), the recognized authority on light pollution.

…The price of commercial LED lighting products continues to drop, and capital cost recovery times for new LED street light installations, once 10 years or more, are now typically less than five years and continue to decline. As barriers to implementation fall, LEDs are gaining momentum as a lighting technology of choice in new outdoor installations.

Blue Light Is Bad

New technical capabilities often come with unanticipated challenges. White LED lighting often has significant levels of potentially hazardous blue light. IDA published a report in 2010 detailing the hazards of blue-rich white light sources. In the years since, scientific evidence has solidified around its conclusions.

Outdoor lighting with high blue light content is more likely to contribute to light pollution because it has a significantly larger geographic reach than lighting with less blue light. Blue-rich white light sources are also known to increase glare and compromise human vision, especially in the aging eye. These lights create potential road safety problems for motorists and pedestrians alike. In natural settings, blue light at night has been shown to adversely affect wildlife behavior and reproduction. This is true even in cities, which are often stopover points for migratory species.

The promise of cheaper outdoor lighting based on electricity and maintenance savings from LED conversion should be weighed against other factors, such as the blue light content of white LEDs. Blue-rich sources are the most efficient LEDs in terms of the conversion of electricity to light, and therefore have the lowest electricity cost to produce a given amount of light compared to “warmer,” less efficient white LED lamps. Every effort should be made to diminish or eliminate blue light exposure after dark.


IDA Recommends

There are already many white LED options now available on the outdoor lighting market and that number will only rise in the future. IDA has developed a set of recommendations for those choosing lighting systems. These suggestions will aid in selecting lighting that is energy and cost efficient, yet ensures safety and security, protects wildlife and promotes the goal of dark night skies. These include

  • Always choose fully shielded fixtures that emit no light upward
  • Use “warm-white” or filtered LEDs (CCT < 3,000 K; S/P ratio < 1.2) to minimize blue emission
  • Look for products with adaptive controls like dimmers, timers, and motion sensors
  • Consider dimming or turning off the lights during overnight hours
  • Avoid the temptation to overlight because of the increased luminous efficiency of LEDs
  • Only light the exact space and in the amount required for particular tasks

98-year-old fire station a ‘high-performing energy system’

From the 9/30/15 York Weekly story written by Deborah McDermott:

YORK – There was, literally, energy to spare at the York Beach fire station Saturday afternoon, as a crowd of more than 50 residents and well-wishers from throughout the region came there to learn about how the department reduced its energy bill from $325 to less than $1.52 in a year.

The York Beach Fire Department dedicated a 28-kilowatt solar power system installed on the roof of the station Saturday.

And in the process, they learned that the building has become a model of efficiency and a harbinger for future town building projects.

The station built in 1917 now has a 28,000-kilowatt solar panel array on its roof, new insulation in the walls and roof, all new light-emitting diode, or LED, lights throughout the building, and a heat pump that is providing cooling and heat to the second floor.

“They say timing is everything. Well, the timing was perfect,” Fire Chief Dave Bridges said, because the energy committee approached the chief just as the department was getting ready to renovate the second floor room used as a bingo parlor. “It just all came together. Would I have done it on my own? No. But I commend the committee for approaching us. The summer people commented tremendously on the solar panels.”

York Energy Steering Committee chair Rozanna Patane said the beauty of the collaboration is that “now we can say we can retain the historic function of a 100 year old building while at the same time turning it into a high-performing energy system.”

The savings from the solar array has been “very good, but more importantly we have reduced the amount of carbon dioxide in the atmosphere. The energy saved here is equivalent to taking 50 cars off the road or planting 200 acres of forest,” she said to much applause.

Selectman Torbert Macdonald called himself an “old solar warrior” who was a state planner in Augusta when Jimmy Carter was president and introduced energy efficiency measures. “He was a much maligned enemy of big oil. For 35 years we’ve been listening to the lies of big oil saying what we really care about is cheap energy.” The fire station project should remind everyone that there are those “who care about the planet,” he said

Bridges said the project was such a success, “hopefully this is just the beginning and there will be other departments that will take on the challenge.”

In an Age of Cheap Solar Does Efficiency Still Matter?

An expert from the Rocky Mountain Institute argues that solar energy may be more glamorous, but efficiency, the old workhorse of green buildings, remains a winner, just not in all cases.

“Efficiency first” is the mantra in green and net-zero buildings; you always do energy efficiency first and then cover the remaining balance of energy needs with renewables such as rooftop solar. This is almost a moral code for green buildings. But in today’s world of rapidly falling costs for renewables, the tipping point between cost-effective efficiency and solar is shifting.Solar vs efficiency

The cost of saving energy through efficiency measures has typically been three to five times lower than any of the renewable sources of energy. Efficiency, as a bundle on a project, typically costs $0.00–0.02 per kWh. Solar-generated electricity has come from $0.20 or more per kWh down to $0.07–0.15 per kWh. And costs are expected to drop a further 25 to 50 percent in the coming few years. We have found that the most-expensive efficiency options—adding another pane of glazing to the windows in a mild climate, daylighting basement spaces, using complicated and sometimes unreliable control systems to harvest the last bit of energy—can’t compete with the new lower cost of solar. Inching incrementally toward deeper efficiency gets more expensive per kWh of energy saved. But is piling on more solar always the best solution?

Addressing both environmental destruction and social inequality

Just how dumb do they think we are?

Who would believe that destroying the ecosystems on which all life depends, while dis-employing more and more people, is somehow good for the economy? Whose economy?

But that’s exactly the fiction that has been successfully marketed to us: jobs versus the environment.

The ethics of climate change

As a global and long-term problem, climate change presents a huge ethical challenge. Climate change is the consequence of a huge number of small acts, which individually are not intended to cause harm. Moreover, the main victims of climate change – future generations and people in vulnerable countries – are distant in time and space . . . → Read More: The ethics of climate change
