Climate change is our grand narrative now

There is the story of our personal lives: our family, our friends, our jobs, our hobbies. There is the story of our communities: our civic, religious, business, artistic and recreational lives. There is the story of our nations: their internal political struggles and their struggles with each other.

But now, there is one grand narrative which ties us all together, whether we want to be connected or not, whether we are preoccupied with our personal, community or national narratives or not. That is the narrative of our changing climate and the resulting threat to the continuity of our world civilization. The climate talks in Paris are but one expression of this new reality.

Even people who oppose doing anything about climate change are forced to talk about it. Even people who somehow have convinced themselves that climate change is not happening and oddly, in the same breath, claim that humans have nothing to do with this thing that is not happening--even those people confirm by their very framing of the issue that they are firmly situated inside this narrative.

Genetically engineered salmon: What could possibly go wrong?

As U.S. regulators cleared genetically engineered salmon for sale in the United States last week, they opened the door to what many scientists already feel is inevitable: The escape and reproduction of GE salmon in the wild and the possible destruction of competing wild species.

Under the U.S. Food and Drug Administration-approved application, the company behind the so-called AquAdvantage Salmon, Aqua Bounty, can only raise such salmon in land-based tanks with "multiple and redundant levels of physical barriers to prevent eggs and fish from escaping." These barriers are described in detail and suggest that it will be very difficult for any eggs or fish to escape into waterways.

The FDA said it considered four interrelated questions about confinement of the fish:

1. What is the likelihood that AquAdvantage Salmon will escape the conditions of confinement?
2. What is the likelihood that AquAdvantage Salmon will survive and disperse if they escape the conditions of confinement?
3. What is the likelihood that AquAdvantage Salmon will reproduce and establish if they escape the conditions of confinement?
4. What are the likely consequences to, or effects on, the environment of the United States should AquAdvantage Salmon escape the conditions of confinement?
   

Syria, climate change and the horror in Paris

As the world mourns those who died in Paris last week in a killing spree for which the Islamic State in Iraq and Syria (ISIS) has claimed responsibility, reporters and commentators have been discussing the motivations behind the attacks. I'm not sure that any so far has considered whether one can draw a straight line from a severe drought in Syria to these mass killings. My own answer is that if the line is there--and I think it is--then it has taken many twists and turns before arriving in Paris.

Even so, it might be worthwhile for those who will soon be gathering in this bereaved city in order to negotiate a new worldwide climate treaty to understand any such connection. For in the background behind these events, there is a Syria starved of water almost surely because of climate change.

A study released earlier this year suggested that the first link in the causal chain that led to the current conflict in Syria was a severe drought lasting from 2006 through 2009, a drought that yielded some of the strongest evidence yet for the link between climate change and increasingly extreme droughts.

Getting it wrong on recycling

Let's see what those disparaging America's rate of recycling as "too high" either get completely wrong or fail to understand. You can read recent commentary suggesting that the recycling rate is too high here, here and here.

The number one complaint is that it costs more to recycle some categories of waste than to put them into a landfill. What the critics fail to comprehend is that unlike a couple of generations ago when most landfills were owned and run by local governments, today most are run by profit-making enterprises such as Waste Management Inc. and Republic Services Inc. which haul some 80 percent of the nation's refuse. Those enterprises developed their large centralized landfills for the purpose of keeping down their disposal costs.

Since the private waste disposal industry has organized its infrastructure around cheap landfill disposal, it's no wonder that landfilling seems like the most cost-effective option. It follows that if we Americans had built a waste infrastructure with the goal of zero waste as Germany did, our infrastructure would naturally have delivered lower costs for recycling than it does.

Exxon: We knew climate change was a real threat (but we didn't want you to)

One of the big complaints about climate change deniers is that they don't fund any genuine primary scientific research into climate change.

We are used to deniers extracting out-of-context passages from existing legitimate climate research and pretending those passages support the denialist position. But wait...we now know, thanks to recent coverage by Inside Climate News and the Los Angeles Times, that at least one climate change denier did fund a great deal of legitimate climate research.

And, what did that research show? It showed that climate change is real, is caused in great measure by human activities and has the potential to disrupt human society significantly. To be fair, when Exxon Corp. (now Exxon Mobil Corp., the world's largest publicly traded oil company) engaged in this research in the 1970s and 1980s, it was genuinely trying to understand the relationship between carbon dioxide emissions and climate change. During that time Exxon scientists collaborated openly with prominent academic and government researchers and were even praised for their commitment and professionalism.
