Ambitious #climate goals are bringing #cities and counties face-to-face with a serious reality: the need for carbon dioxide removal in addition to #decarbonization. As some local governments start to look at carbon removal strategies, experts say the public sector entering the ring could help bring down the cost for everyone. My story for Smart Cities Dive:

One of the things we do at Cipher News is turn a spotlight on quality reporting happening across the climate landscape. Here are a couple of pieces that I called out this week in our "Top Reads/Hot Takes." https://lnkd.in/eg_cHZmm In the pipeline construction business, private inspectors report safety concerns to developers, but there isn't sufficient enforcement that problems get fixed, according to an E&E News investigation. This excellent reporting exposing a "potentially deadly gap in the regulatory apparatus" is especially critical, reporter Mike Soraghan points out, because we're going to need lots more pipelines. https://lnkd.in/e4yj6bAj Salesforce's Marc Benioff and the World Economic Forum launched their goal to plant or conserve one trillion trees by 2030 at Davos in 2020. So far, the project is behind schedule, Sophie Alexander at Bloomberg reports. The number of trees pledged to the effort is less than 15% of the goal and 2.6 billion trees, less than 0.3% of what's needed, has been planted or conserved, according to admittedly imperfect records. Have a scroll through CipherNews.com to see what my other esteemed colleagues — Amy Harder, Amena H. Saiyid, Anca Gurzu and Bill Spindle —are reading and why.

I found Ezra Klein's interview with Hannah Ritchie really thought provoking. Both are self-proclaimed "techno-optimists" who think that meaningful action to mitigate climate change will depend on having viable, agreeable substitutions for the things people want and are accustomed to having--energy, vehicles, meat, etc.--no real behavior change--or god forbid, sacrifice--required. For this reason they are more optimistic about the rapid uptake of renewable energy and less so about en masse shifts in diet (more plants; fewer cows) that could help address the biodiversity crisis. All the more reason to push for policy that well help advance these substitutions. Which depends on electing the right policymakers with the mandate to do so. So...back to the battle for hearts and minds, right? What do you think? #climatechange #climateaction #biodiversity #renewableenergy https://lnkd.in/gmPqR8Zj

A landmark multiyear congressional investigation into the role of fossil fuel companies in obstructing climate action and misleading the public has revealed new findings and insights based on internal industry documents. The findings, detailed in a new joint report released April 30 by Democrats from the House Committee on Oversight and Accountability and the Senate Budget Committee, show how major oil and gas companies continue to dodge responsibility for the climate crisis while disseminating disinformation and deploying duplicitous tactics in attempts to preserve their extractive business model and protect their public image. “Our investigation uncovered public pledges undermined by private memos, public support for climate policies contradicted by private emails, rampant evidence of deception and corporate doublespeak,” Sen. Sheldon Whitehouse (D-RI), chairman of the Senate Budget Committee, said in his opening remarks during a May 1 committee hearing about the new report.

Public service announcement to all those working on enhanced rock weathering: a "dissolution rate constant" is not the same thing as a "dissolution rate". There is an epidemic of this mistake in journal literature, where the mistake gets cited and re-cited over and over. Just today I found this mistake in three journal articles (https://lnkd.in/gTBPJwXu; https://lnkd.in/geUzMbYx; https://lnkd.in/gVV8knWa). While two of them passively made this confusion by just reporting values on a table (but risk having its readers make this confusion), the article that these two other articles cited went as far as to say this: "Anorthite has a Ca content smaller than wollastonite, and dissolves 60 times more quickly" (Manning and Theodoro, 2020). This is incorrect, as clearly shown both mathematically and graphically in one of my papers (https://lnkd.in/gQkHfKXv). A "dissolution rate constant" is a constant. Evidently, a constant is not a rate. Rates are a function of variables like temperature, pH, etc., so they cannot be "constants". These issues stem from researchers not carefully reading the meaning of the data presented by Palandri and Kharaka (2004). In that report, the values and equations are correctly presented, but it takes critical interpretation to know how to use them, not simply copy/pasting values from tables thinking that they are rates. At least AI is not confused (yet). I just asked it which mineral weathers fastest (wollastonite vs. anorthite) and it says that wollastonite "is known to be among the fastest reacting silicates", but it does not conclusively say that anorthite weathers more slowly as it cannot find data. The above-quoted sentence is behind a paywall on Elsevier, so it did not find it. Am I letting the genie out of the bottle by writing it here...? Time will tell.

Now available in e-book and hardcover, "Proven Climate Solutions: Leading Voices on How to Accelerate Change". I was honored to contribute a chapter beside luminaries such as Mark Jacobson, Kate Gaertner, Robert Howarth, Luxmy Begum, Ph.D., P.Eng., PMP and Bill McKibben. "Fifteen climate experts combine forces to present a plan for slowing and ultimately preventing further destruction to our planet. As governments and businesses continue to set climate goals for reducing carbon emissions and slowing global warming, scientists, engineers, and policymakers are using cutting-edge research to introduce new climate technologies and strategies for achieving and potentially surpassing these goals. Presented by world-leading climate scientists and futurists, Proven Climate Solutions offers a dynamic, evidence-based action plan that uncovers the hard work, dedication, and best practices of climate heroes who are accelerating change and winning the battle to protect our environment." https://lnkd.in/gpkvwwvg

Bats! Bat populations are under strain, especially as a result of the "white nose syndrome" that is devastating several species in North America. #Bats are also key beneficiaries of #nativeplants and the #insect populations these support. You can help bats in your area by creating or allowing natural settings that provide food, shelter, and water for these little creatures, the only mammals capable of true flight. Some 70% of bats eat only insects (they are obligate insectivores), so they do a great job of eliminating the insects that ... you help propagate ... with native plants and other habitat features. 🤷♂️ That's perhaps the point of #rewilding -- it's a good idea to let nature win sometimes, in some places. The biologist E.O. Wilson and many others have argued that "nature needs half", and we humans should, if we are to have a hope of staying around for the long term, learn to get by on no more than the other half: “Half the world for humanity, half for the rest of life, to make a planet both self-sustaining and pleasant” (Wilson, _The Future of Life_, 2003). Bats often nest in cavities in old trees, which are something of a rarity in tended urban landscapes. So one way we can help provide habitat is to build a bat box. In Canada, we're still figuring out the best way to make these, and if you have installed one on your home (share a photo!) you can help inform the science: "The Canadian BatBox Project (Wildlife Conservation Society) aims to create ideal conditions for bats by gathering information from individuals who have installed them. The program hopes to discover the optimal box design for bats based on region and species. If you are in Canada and have a bat box (or plan to get one), you can fill out this survey [ink in the article] to support their research."

A new narrative is beginning to take hold around #climate change and the #energy transition, as the push to #decarbonize adapts to the tricky reality that the climate emergency is no longer at the top of the public agenda. Some thoughts on how to connect climate, #housing, and #affordability so that everyone wins.

🗣 Are you a local reporter, TV producer, or meteorologist covering heat in North / Central America this summer? Here are the facts about the last heat wave: * Human-induced warming from burning fossil fuels made the 5-day maximum temperature event about 1.4 degrees hotter and about 35 times more likely. For nighttime temperatures, this is about 1.6 degrees hotter and about 200 times more likely. * The extreme heat in North and Central America has resulted in more than 125 heat-related deaths in Mexico since March, thousands of cases of heat stroke, and power outages. * We likely do not know the full picture of heat-related deaths, since they are usually only confirmed and reported months after the event, if at all. ---- See all the data in this World Weather Attribution report: https://lnkd.in/d6fsdeGQ --- Find tips and story ideas to report on extreme heat in our new newsletter, Locally Sourced, ¡también en español! 👉 https://lnkd.in/dAYsqQS5

Good article. USA Today actually created a decent structure in how they measure the climate resilience of a city. But...like most media outlets, they still don't get the difference between climate adaptation and mitigation. Most of their metrics are related to adaptation, but they have one "Number of renewable energy tax and financial incentives for city residents" that is not adaptation. If it was related to the 'resilience' of the energy grid in a city to the impacts of climate change, then yes, include. This metric simply refers to tax incentives for renewable energy within a given community. That's carbon mitigation. The media still can't get in their heads around the fact that the adaptation sector is an emerging sector, with its own focus areas (please relevant folks, keep mitigating carbon! But adaptation is something different.). Lots of familiar names in the adaptation experts they interview, so that's great. #climatechange #adaptation

If you think about how to cope with climate change, #mapping is probably not the first thought that pops up in your mind. But an accurate and comprehensive map is surprisingly crucial to the success of #adaptation efforts, especially for dwellers of urban #slums. This is what we found from Monrovia, Liberia, and similar slum mapping projects are happening worldwide.

June 18, 2024 - By University of Massachusetts - Amherst, "Native species cannot move fast enough on their own to avoid climate-driven chaos --- An international team of scientists has recently found that non-native species are expanding their ranges many orders of magnitude faster than native ones, in large part due to inadvertent human help. Even seemingly sedentary non-native plants are moving at three times the speed of their native counterparts in a race where, because of the rapid pace of climate change and its effect on habitat, speed matters. To survive, #plants and #animals need to be shifting their ranges by 3.25 kilometers per year just to keep up with the increasing temperatures and associated #climacticshifts—a speed that #nativespecies cannot manage without human help. Led by scientists at the University of Massachusetts Amherst, the team includes researchers from New Jersey, Michigan, Colorado and Hawaii in the U.S., as well as Sevilla and Zaragoza in Spain and was published (https://lnkd.in/d4KKQjaJ) in Annual Reviews of #Ecology, #Evolution and #Systematics. Non-native species (red) are spreading much faster than native species (blue). The dotted line indicates how fast species need to move to keep up with climate change. “We know that the numbers of #invasiveplantspecies are increasing exponentially worldwide,” says Bethany Bradley, professor of environmental conservation at UMass Amherst and the paper’s lead author. “We also know that #plantnurseries are exacerbating the climate-driven spread of #invasives and that confronting invasives is one of the best ways to prepare for climate change. What we wanted to find out is how fast both native and non-native species are moving right now, and how far could they go.” To figure out how fast species are moving, Bradley and her colleagues comprehensively surveyed a vast trove of previously published papers and publicly available datasets on how far and how fast both native and non-native species, representing different taxa and various ecosystems, have been moving. An important subset of this search was to compile data showing how humans are helping to accelerate the spread of non-native species, either accidentally, such as when a particular species finds itself in a shipping container that travels between continents, or intentionally, when a gardener buys an invasive ornamental from a nursery and drives it back to their home. The conclusion that Bradley and colleagues reached is that land-based species—including plants—need to be moving at more than 3.25 kilometers per year if they want to stay ahead of #climatechange, while marine species need to be moving at 2.75 kilometers/year. Unfortunately, native species are only managing to move an average of 1.74 kilometers per year. Non-native species, however, are spreading at about 35 kilometers per year on their own. When the human role in spreading non-native species is taken into account, then the rate jumps.." Continue reading

The RMI team says that in this year or next, we'll have hit peak demand for fossil fuels (a fact that is consistent with NOAA's finding that we're emitting more CO2 than ever). The reason for this is that so much renewable energy is about to come online, and it is so goddamned cheap, that we are about to undergo a huge shift in our energy consumption patterns.
