Why don’t we do anything about climate change?

News: Our climate–Earth’s climate–is changing. It’s a fact, not a theory, not a guess. Overall, our climate is getting warmer; we will see fewer periods of “normal weather”, there will be longer stretches of extreme temperatures (hot and cold), longer periods of drought interspersed with sporadic episodes of torrential rain or heavy snow. Ice at the Poles is melting rapidly; sea levels are rising. We will see more frequent and more powerful storms, more and larger wildfires, more climate refugees fleeing areas that will become virtually uninhabitable. The areas of the Earth without enough fresh water will grow, large numbers of animal and plant species are declining or becoming extinct, the impacts of climate stress on people will grow including a likely increase in the number of suicides … all of this and more is happening right now and will continue. Our children, our children’s children, and future generations will pay the price of our collective inaction, greed, and folly.

So, why don’t we do something about it? Why didn’t we do something about it? There was research back in the 1970’s and 1980’s that pointed clearly at what was going to happen if we did not act. But, we–collectively–have done almost nothing.

Why?

Because, humans are strange creatures. Psychologically, “humans are naturally prone to making short-term decisions as opposed to pursuing longer-term collective interests.” Short-termism may be one of the greatest threats today to humankind. People are impacted much more by the concrete rather than the abstract. And, climate change is often presented in a very abstract way. Charts, graphs, text–it will impact us but we don’t know exactly how much and only sometime in the hazy future. In contrast, “concrete information tends to convey greater urgency, triggering the belief that we need to act now.” Concrete information is also more likely to trigger strong emotions. “And, concrete experiences can have powerful effects.”

For example, watching unprecedented spring flooding in the midwestern U.S. on TV or your computer from the comfort of your (dry) living room makes the event seem abstract. It’s happening over there, somewhere else; it’s not happening to me or in my town. But, having your own house flooded, your possessions destroyed, your town submerged, your life upended–that is very concrete and may cause you to move away from the river and start a new life, or at least to buy flood insurance, etc.; it may cause you to take immediate, real action.

So, what does this mean for climate change? Is there a lesson here that can assist long-term beneficial collective action to reduce, mitigate, and adapt to climate change?

Make climate change concrete, make it personal, show the impact on children, our children, especially. Make it real enough that we extend our default, selfish human self-interest from the short-term to the future, even extend it to a concern for other species … that may drive action and make us collectively more mindful of our impact on the future.

Microplastics now found in the mountains

Microplastics now found in the mountains

News: Microplastics–tiny fragments of plastic waste–can be “ingested and inhaled by humans.” There are many news reports and studies that have shown that microplastics can now be found in all areas of the oceans–with severe impact on ocean life and increasing impact on people that live near the oceans. New research confirms that microplastics can now also be found in mountainous areas remote from cities. Specifically, researchers discovered microplastics “falling from the sky in dust, rain, and snow” in the Pyrenees mountains in southwestern France over 60 miles from the nearest city.

When analyzed, it was found that these microplastics mostly came from the single-use plastic packaging used in shipping. When swept up into the atmosphere, these tiny bits of plastic may float well over 60 miles before “falling back to Earth.” Extrapolating from the amount of plastics collected in the Pyrenees, the researchers estimate that some 2,000 tons of microplastics fall from the atmosphere over France each year.

Microplastics of this size “are virtually impossible to clean up.” The only solution “is to produce less in the first place.”

Good carbs and high fiber

Just as with fats, there are “bad carbs” and “good carbs” (and conflicting dietary claims and sometimes controversy). Importantly, good carbs are high in fiber but not high in sugar. Good carbs include fiber-rich whole grains, legumes, fruits, and vegetables.

Despite the proponents of low-carb diets, recent scientific reviews and research indicate that for long-term health (and not just immediate weight loss) people should eat more carbs, not less–but they should consume good carbs rather than bad.

The reviews and research suggest that consuming more good carbs as part of one’s diet (and that’s significantly more than what most people currently eat) can lead to 15-30% decreases in mortality and the incidence of heart disease, stroke, diabetes, and colorectal cancer. Other benefits can include weight loss, lower blood pressure, and lower cholesterol. “The relationship between a high-fiber diet and lower disease risk could be causal.”

Politics and Fear

The fastest way to dumb down a population is to scare them

Whipping up fear is a common tactic in politics. Providing stark, seemingly life or death choices, us versus them, scapegoating, creating a false bogeyman to distract from real problems, using lies and disinformation … fear is used because it often works.

Fear breeds anxiety and stress, and “anxiety increases the attention to negative choice options, the likelihood that ambiguous options will be interpreted negatively, and the tendency to avoid potential negative outcomes, even at the cost of missing potential gains.”

What does this mean? Why does fear work? Fear pushes people to see only the negative, to judge negatively even positive or neutral options, and to even act against their own best interests in order to avoid a suggested calamity.

Fear is corrosive; fear is the friend of dictators and authoritarian/totalitarian governments.

But, fear is also a state that we help create within ourselves. Just as we can allow fear to build and affect our lives, we can also disrupt it (though it is not easy to do that in times of high anxiety). One way to beat fear is through knowledge and understanding. Dig through the slogans and disinformation, get to the facts.

Google tracks the locations of cellphone users across the United States. Law enforcement increasingly uses this database (called “Sensorvault”) as part of trying to solve crimes.

But, innocent people are sometimes targeted–arrested and jailed. Is this collateral damage acceptable? Is it okay to victimize the innocent in the pursuit of the guilty? Would it be okay if it happened to you? Is there any privacy left in America? Do we care?
