The climate change ‘tipping point’ has already arrived for these 70 U.S. counties

For years now now, we’ve been hearing warnings about 2 degrees Celsius of warming — the global average cautioned against as part of the 2015 Paris accord. But according to a Washington Post interactive published on Tuesday, that so-called “tipping point” has already arrived in many towns across the country.

The earth is warming at an uneven rate. The Post looked at 100+ years of data from over 3,000 U.S counties and found that over 70 have already exceeded 2 degrees C of warming above pre-industrial levels. That translates to 34 million people (roughly 1 in 10 Americans) living in regions that are heating especially rapidly.

So where are the U.S. hot spots? The counties that have already reached 2 degrees C or warming are spread throughout the U.S., but there are some regional trends. The fastest-warming state in the country is Alaska, which may come as no surprise given its recent spate of heat waves and wildfires. In the Lower 48, Rhode Island’s average temperature increase is the first to pass 2 degrees Celsius, with other parts of the Northeast, including New Jersey, Connecticut, Maine, and Massachusetts, not far behind.

While the east coast has been sizzling this summer, the Post found that most regional increases were driven by warming winter temperatures, not summer heat waves. That’s means lakes can’t freeze (causing algae blooms, in some cases) and pests don’t die as per usual in certain historically cold regions. Less snow and ice also means those regions are less able to reflect solar radiation during winter, further feeding into the warming cycle.

The freezing point “is the most critical threshold among all temperatures,” David A. Robinson, New Jersey state climatologist and professor at Rutgers University’s department of geography, told the Post.

Scientists aren’t yet sure why the Northeast is warming so quickly. But experts say these 2-degree C hotspots are like little pieces of the future here in the present, showing us what’s coming.

Of course, climate catastrophes aren’t just about higher average regional temperatures. Cold, heat, flood, drought, and sea-level rise all pose significant risks to U.S. communities, according to a newly released analysis by the group Clever Real Estate. And bad news: The report found that many of the cities most at risk to the impacts of climate change are also the least prepared for it.

Clever Real Estate

There’s some concerning crossover between the Post’s list of rapidly warming counties and the areas identified by Clever Real Estate’s analysis (which was compiled by Eylul Tekin, a Ph.D. candidate at Washington University in St. Louis’ Memory Lab). Four of the top five cities with the “lowest degree of readiness” are located in Southern California (Anaheim, San Bernardino, Santa Ana, and Riverside). The counties in question have reached between 1.8 degrees C and 2.1 degrees C of warming compared to pre-industrial levels.

Parts of New Jersey also didn’t fare well on either list. Essex County has already hit the 2 degrees C warming mark, and Newark snagged the fifth spot on the list of places with the “largest difference between risk and readiness scores.”

So in short, there’s already a lot to sweat in many parts of the U.S. (which is even more reason to take climate action now). To get a better sense of the way your specific area is being affected, check out the two studies we mentioned here and here.

22 states sue the Trump administration over its climate ‘plan’

Twenty-two states and seven cities sued the Trump administration on Tuesday over the Environmental Protection Agency’s new plan for power plants. The lawsuit alleges that the so-called Affordable Clean Energy rule would accelerate the impacts of the climate crisis and impose health and safety risks on Americans.

The challenge — led by the states of New York, Massachusetts, California, Rhode Island, Hawaii, and the cities of Chicago, Los Angeles, New York, and Philadelphia — comes two months after the EPA finalized the plan. The new rule replaced the Obama-era Clean Power Plan that set ambitious goals aimed at weakening carbon emissions coming from power plants. It gives a bit more elbow room to coal-powered stations and allows older ones to stay open longer.

“The science is indisputable; our climate is changing,” New York Attorney General Letitia James said in a tweet. “Ice caps are melting. Sea levels are rising. Weather is becoming more and more extreme. That’s why we are fighting back.”

A recent Harvard study shows that the EPA’s estimated carbon reductions from power plants under the new rule (which are pretty minor) wouldn’t hold up under changing market conditions. In addition, researchers say that the agency underestimated the health effects the rule would have in some states and overestimated its overall economic benefits.

Not that the EPA’s own projections looked pretty. The administration’s analysis found that the ACE rule, compared to the Clean Power Plan, would lead to 1,400 premature deaths by 2030 and would cost Americans $1.4 billion more per year than it saved.

Carbon dioxide emissions in the U.S. increased by roughly 3.5 percent last year. The Harvard analysis suggests that Trump’s new rule could drive emissions even higher by failing to nail down target reductions. Meanwhile, it may result in more cases of respiratory illness, heart attacks, asthma, and early death due to exposure to particulate matter and toxic air pollutants.

The new lawsuit parallels the Republican-led effort to stop the Clean Power Plan in 2015, when 24 states led by Oklahoma sued the Obama administration over the rule. The Supreme Court hit pause on the plan a year later. Soon after President Trump took office, the EPA started crafting a Trump-friendly alternative to the plan.

If you compare the states that sued over the Obama-era rule in 2015 and those that are suing the Trump administration now, it’s no surprise that you’ll see a partisan divide. Only Colorado, Michigan, and North Carolina were part of both lawsuits.

An EPA spokesperson told the New York Times, “EPA worked diligently to ensure we produced a solid rule, that we believe will be upheld in the courts, unlike the previous Administration’s Clean Power Plan.” Only time will tell — it’s possible that the challenge could go all the way to the Supreme Court.

The Constants of Nature

The Numbers That Encode the Deepest Secrets of the Universe

John Barrow

Genre: Science & Nature

Price: $2.99

Publish Date: March 9, 2004

Publisher: Knopf Doubleday Publishing Group

Seller: Penguin Random House LLC


Reality as we know it is bound by a set of constants—numbers and values that dictate the strengths of forces like gravity, the speed of light, and the masses of elementary particles. In The Constants of Nature , Cambridge Professor and bestselling author John D.Barrow takes us on an exploration of these governing principles. Drawing on physicists such as Einstein and Planck, Barrow illustrates with stunning clarity our dependence on the steadfastness of these principles. But he also suggests that the basic forces may have been radically different during the universe’s infancy, and suggests that they may continue a deeply hidden evolution. Perhaps most tantalizingly, Barrow theorizes about the realities that might one day be found in a universe with different parameters than our own.

Seller: OpenRoad Integrated Media, LLC


A “delightfully astute” and “entertaining” history of the mishaps and meltdowns that have marked the path of scientific progress ( Kirkus Reviews , starred review). Radiation: What could go wrong? In short, plenty. From Marie Curie carrying around a vial of radium salt because she liked the pretty blue glow to the large-scale disasters at Chernobyl and Fukushima, dating back to the late nineteenth century, nuclear science has had a rich history of innovative exploration and discovery, coupled with mistakes, accidents, and downright disasters. In this lively book, long-time advocate of continued nuclear research and nuclear energy James Mahaffey looks at each incident in turn and analyzes what happened and why, often discovering where scientists went wrong when analyzing past meltdowns. Every incident, while taking its toll, has led to new understanding of the mighty atom—and the fascinating frontier of science that still holds both incredible risk and great promise.

The Case Against Reality: Why Evolution Hid the Truth from Our Eyes – Donald Hoffman

The Case Against Reality: Why Evolution Hid the Truth from Our Eyes

Donald Hoffman

Genre: Science & Nature

Price: $14.99

Publish Date: August 13, 2019

Publisher: W. W. Norton & Company

Seller: W.W. Norton & Company, Inc.


Can we trust our senses to tell us the truth? Challenging leading scientific theories that claim that our senses report back objective reality, cognitive scientist Donald Hoffman argues that while we should take our perceptions seriously, we should not take them literally. How can it be possible that the world we see is not objective reality? And how can our senses be useful if they are not communicating the truth? Hoffman grapples with these questions and more over the course of this eye-opening work. Ever since Homo sapiens has walked the earth, natural selection has favored perception that hides the truth and guides us toward useful action, shaping our senses to keep us alive and reproducing. We observe a speeding car and do not walk in front of it; we see mold growing on bread and do not eat it. These impressions, though, are not objective reality. Just like a file icon on a desktop screen is a useful symbol rather than a genuine representation of what a computer file looks like, the objects we see every day are merely icons, allowing us to navigate the world safely and with ease. The real-world implications for this discovery are huge. From examining why fashion designers create clothes that give the illusion of a more “attractive” body shape to studying how companies use color to elicit specific emotions in consumers, and even dismantling the very notion that spacetime is objective reality, The Case Against Reality dares us to question everything we thought we knew about the world we see.

Cutting Down on Lawn — Alternatives to Grass

Lawns are green in color only, and the odds are good that you’re sick of mowing. You could save time by ignoring lawncare myths, and there are ways to reduce the water and energy you waste on your lawn, but even the most eco-friendly lawn is still a lawn.

Here are some tips for reducing the amount of the lawn in your yard even if you’re not an avid gardener.

Shrubbery

There’s a good chance that you have at least a few trees and bushes planted around the edges of your lawn. Add to the existing woody plants in your yard to create deep shrub borders. Plant native species and mulch them all the way to the drip line to reduce the need for water and protect trunks from lawnmower damage. Once established, native shrub borders can survive without supplemental water most years, and need pruning no more than once a year.

Berry Beds

Raised beds create a sense of structure in the landscape that looks tidier than shrub borders. They also keep cane berries like raspberry and blackberry from spreading.

Filled with flowers or vegetables, raised beds can be just as much work as lawn. But filled with berries, all they need is sun and water and you’ll be rewarded with fresh fruit. But don’t be surprised if you get inspired to take up beekeeping to keep those harvests going.

Unmown Grasses

Lawn grass is not the only kind of grass, in fact, it is one of the least interesting or useful forms.

Ornamental grasses can be used to create sophisticated planting designs or to recreate native prairie. If you choose native species, you can free yourself from both watering and mowing, so you’ll have plenty of free time to sit back and enjoy the butterflies and other wildlife attracted to your certified wildlife habitat.

But research horticultural varieties before planting — many ornamental grasses are invasive species. If a grass doesn’t belong in your region, don’t plant it.

Ground Covers

There are probably areas of your lawn that don’t get very much — if any — foot traffic. For those areas, other ground covers may be more appropriate than grass, especially in shady areas. As with grasses, many ground covers can be invasive. Consider native plants like kinnikinnick or wild ginger — find out what grows in your region.

Few ground covers are as hardy as lawn grass. But clover, herbs like creeping thyme, and even moss can tolerate some foot traffic. The benefit, though, is groundcover that requires relatively little water compared to the traditional lawn.

Unplanted Areas

Although permeable pavers can reduce the amount of grass you have to deal with while still allowing rainwater to drain through the gaps, an entirely paved yard is probably too much. Gravel, on the other hand, can be a lawn substitute without making your yard look built over. Combining large areas of gravel broken up with a few drought-tolerant plants is best suited to dry climates and desert landscapes.

There’s no need to rip out your entire lawn if you don’t want to. But you can save time, energy, and water by reducing the area of your lawn. Try one or more of these strategies to chip away at the edges of your lawn. You might find yourself with a prettier yard and more time to enjoy it.
