Tiny lanternfish is vital to carbon sequestration in ocean.

Though burning fossil fuels is the primary cause of global warming, fossil fuels could also be driving climate change via a completely different mechanism involving ocean plastic debris and tiny, bioluminescent fish living hundreds of meters beneath the ocean’s surface.

Lanternfish (aka myctophids) are only a few inches long typically but so ubiquitous that they account for over half the ocean’s total fish-mass. They are vital to the ocean’s ability to sequester more carbon than all the world’s forests do on land through a daily mass migration that plays out in all seven seas.

By day, lanternfish avoid predators in deep, dimly lit waters, but they ascend nightly to the surface to gorge on carbon-rich plankton before descending back down where they deposit their carbon-rich poop. They also sequester carbon when eaten by larger fish.

Carbon sequestration by lanternfish is central to the overall role of marine environments in reducing human-caused CO2 emissions in the atmosphere – by an estimated 20-35 percent.

Thus, anything harmful to lanternfish could hinder the ocean’s capacity to act as a carbon sink. Alarming evidence that small bits of floating plastic debris resemble the plankton lanternfish feast on could spell trouble for them and, consequently, the climate. Read the rest of this entry »

I fancy myself an environmentalist. I recycle, backyard compost, have rooftop solar, rarely use AC or heat, drive a hybrid, don’t have a lawn and eat vegetarian.

Yet the truth is I am as responsible for climate change as the next guy. Here’s why.

Doing those things definitely makes me feel good about myself, but none of my personal actions move the world measurably closer to solving the climate crisis. My journey to this conclusion started by first looking into my personal carbon footprint using readily available online tools.

The U.S. EPA’s carbon footprint calculator, for example, looks at three sources of greenhouse gas (GHG) emissions: home utilities for heating, cooling and cooking; vehicle fuel efficiency and miles driven; and waste generation. In these areas, my carbon footprint was roughly half that of other people living in my zip code, suggesting my eco-conscious efforts are paying off.

However, it’s eye-opening that roughly two-thirds of Americans’ GHG emissions are embedded in so-called “indirect” emissions released during the production or manufacture of other things we consume, such as food, household supplies, apparel, air travel, and services of all types, according to an in-depth analysis by the Center for Global Development, a non-profit policy research organization. Another way to understand indirect emissions is to think of the money spent on everything not included in the EPA’s more limited carbon footprint calculator.

Though President Trump has withdrawn the U.S. from the 2015 Paris Climate Agreement, this is no time for the 70 percent of Americans who believe climate change is happening to recoil in defeat. Rather, we should feel empowered that a 2016 post-election poll of registered voters found that majorities of Democrats (86%),  Independents (61%) and Republicans (51%) alike wanted the United States to participate in the accord and that two out of three voters said the U.S. should reduce its greenhouse gas emissions regardless of what other countries do.

Thus, it is exactly the time to speak out against the misguided actions of The White House by taking decisive steps well within our reach as individual citizens and communities. After all, the Paris Agreement is only a broad-stroke commitment from participating countries to collectively limit global warming to 1.5 to 2.0 degrees Celsius (°C) compared to preindustrial levels. It has always been true that only Congress and legislative bodies at the state and local level, not the President, can enact laws that can move us from a fossil fuel to a sustainable energy economy.

Here’s what’s happening at various jurisdictions around the nation already.

Irvine: The Little Engine That Could

Irvine led on restoring the ozone layer and should lead now on climate change.

Ozone Depletion: The First Global Environmental Crisis

The depletion of the protective ozone layer in the Earth’s atmosphere by man-made chemicals was the global community’s first environmental crisis.  Today, climate change, largely attributable to greenhouse gas emissions from burning fossil fuels, is the second and far more frightening crisis.

The people of Irvine can be proud that actions taken by the City Council in 1989 were instrumental in creating a blueprint at the local level for carrying out the aspirations set forth in the 1987 Montreal protocol, the international agreement to restore the ozone layer.  It is widely hailed as the most successful global environmental treaty ever.  As the global community today faces the reality that unchecked global warming could unleash catastrophic effects impacting all future generations, Irvine can and should resurrect the same purpose and determination that inspired the City to make a difference back then.

In 1974, scientists at UC Irvine, led by Nobel laureates (1995) F. Sherwood Rowland and Mario J. Molina, predicted that the Earth’s protective ozone layer would be seriously diminished by the rampant use of halogens — chemicals, such as CFCs (chlorofluorocarbons) and other ozone-depleting compounds then used as refrigerants, spray can propellants, and solvents.  The ozone layer acts as a shield, preventing the most harmful ultraviolet radiation in sunlight (UVB) from reaching the Earth’s surface.  Excessive exposure to UVB is known to cause not only sunburn, skin cancers and cataracts but also damage to crops and reduction of plankton populations vital to the ocean food web.

It wasn’t until 1985 that the infamous hole in the ozone layer over Antarctica was discovered, as Rowland and Molina predicted. That triggered the international alarm that led to the Montreal Protocol.  Because action at the federal level was painfully slow in coming, the Irvine City Council, then led by Mayor Larry Agran and City Councilmember Cameron Cosgrove, boldly passed the most far-reaching, legally enforceable measure anywhere to eliminate CFCs and other ozone-depleting substances.  This remarkable ordinance prohibited using CFCs and other targeted halogens in most industrial processes in the City of Irvine.

The City Council, in taking responsible action at the local level, believed that other jurisdictions would be empowered to use Irvine’s ordinance as a model.  That is exactly what happened in many cities and counties across America and throughout the world, and today we know that the hole in the ozone layer is shrinking and we have overcome that global environmental crisis.

Within moments of Donald Trump’s inauguration, the White House web page on climate change was purged, and on March 28 Trump ordered the dismantling of the Clean Power Plan which was designed to cut greenhouse gas emissions from power plants. Many members of Congress are still openly climate change skeptics or deniers.

In a representative democracy such as ours, one might conclude that most Americans don’t believe in or are unconcerned about climate change. Two recent polls reveal how wrong this is.

Seventy percent of Americans believe global warming is happening, according to the Yale Project on Climate Change Communication which used a national survey of over 18,000 adults spanning 2008 to 2016. Fully 75% favor regulating CO2 as a pollutant.

Consistent with this, 62% of Americans responded “no” when asked if President Trump should “remove specific regulation intended to combat climate change” in a nationwide poll just released on March 8 by Quinnipiac University. Furthermore, a Yale Project post-election poll of Trump voters found that more than six in ten support taxing and/or regulating the pollution that causes global warming.

Climate Change: No One is Exempt

1309_consensus-graphic-2015-768pxLuckier Americans are insulated from many everyday worries, like struggling to pay the rent or mortgage on time. Some even enjoy life in gated communities, fine dining and first-class travel. But, just as money is no guarantee of happiness, neither is it assurance of protection against all of the frightening impacts of unchecked global warming.

2016 was the third straight year that the Earth’s temperature was the hottest on record. Contrary to what one might hear in politicized discourse, climate scientists are nearly unanimous in concluding climate change is happening and is the result of burning fossil fuels for energy.

The United Nations and scientific organizations worldwide warn that effects of climate change are already being felt and that the Earth is more than half the way to a temperature increase of 2 degrees Celsius, beyond which runaway global warming will produce irreversible, catastrophic effects. Even worse, if global greenhouse gas emissions remain on their current trajectory, children living today can expect to experience the fallouts of a temperature increase topping 4 degrees Celsius by end of this century.

Despite such dire predictions, Americans, rich and poor, overwhelmingly believe climate change is not a threat to them personally. In a nationwide, county-by-county poll conducted in 2015, in not a single county did the majority of respondents believe climate change will affect them personally, though majorities in 99% of counties felt future generations would be.

The difficulty Americans have in understanding their own vulnerability to climate change stems in part from failing to see beyond the direct effects of climate change – heatwaves, droughts, storms and floods – to appreciate all the indirect effects on health and safety from air pollution, spread of infectious diseases, food and water shortages, population migrations and conflicts.

These indirect effects of climate change place everyone at risk. Read the rest of this entry »


Greening Your Wardrobe

apparel-clothingWhat typically comes to mind when contemplating our personal environmental footprint is the energy efficiency of the car we drive, how religiously we recycle, and maybe whether or not we have a water thirsty lawn. However, everything we do and own has impacts on the environment, and that includes the choices we make in dressing ourselves.

This point was driven home in a smart little book published in 1997 titled, “Stuff: The Secret Lives of Everyday Things,” which describes the planetary impacts of everyday material goods. One chapter details what goes into producing a wardrobe basic, the cotton/polyester blend T-shirt.

A few highlights include the overseas extraction of the crude oil from which polyester is synthesized, the energy and pesticide intensive process of growing and harvesting cotton, and transporting milled fabrics abroad and back again so they can be sewn into T-shirts by cheap foreign labor.

From this T-shirt saga emerges a simple truth: The T-shirts with the least environmental impact are the ones you already own, or maybe ones purchased at a secondhand shop.

Nonetheless, clothes do wear out and wardrobe adjustments become necessary when we take on new jobs or sports, change weight or treat ourselves to the latest fashion. So the question remains how to make apparel selections which better protect both the environment and the people involved in the production process. The good news is that there are already more sustainable clothing options on the market, plus there is game-changing movement within the apparel industry to provide consumers with a point of purchase “index” conveying the environmental footprint of items being offered.
