Trees may sequester CO2, but older and rotting trees also are primary emitters of N2O (296X more GHG potential than CO2) and CH4 (28X more). Imagine two identical stacks of timber, one is left to rot in the forest, and the other is efficiently burned. The first emits a dramatically larger global warming effect with its CH4 and N2O, than the second stack, which converts mostly into CO2. To remove forests from being productive timberlands only ensures more overall global warming effect occurs. This problem is only recently being discussed. From Yale University, "After water vapor and carbon dioxide, methane is the most important greenhouse gas. In fact, molecule for molecule, it is a much more potent planet-warmer than CO2. Human sources – most prominently rotting landfills... – have raised atmospheric concentrations by around 250 percent. They are reckoned to be responsible for around a fifth of global warming. But there are many natural sources, too, including microbial activity in wetlands, termites, the guts of ruminants, and, it now turns out, most of the world’s trees." https://e360.yale.edu/features/scientists-probe-the-surprising-role-of-trees-in-methane-emissions .
Numerous other studies show the truer emissions. https://www.nature.com/articles/srep23410; "We show for the first time that mature Scots pine (Pinus sylvestris L.) trees consistently emit N2O and CH4 from both stems and shoots. The shoot fluxes of N2O and CH4 exceeded the stem flux rates by 16 and 41 times, respectively. Moreover, higher stem N2O and CH4 fluxes were observed from wet than from dry areas of the forest. The N2O release from boreal pine forests may thus be underestimated and the uptake of CH4 may be overestimated when ecosystem flux calculations are based solely on forest floor measurements. The contribution of pine trees to the N2O and CH4 exchange of the boreal pine forest seems to increase considerably under high soil water content, thus highlighting the urgent need to include tree-emissions in greenhouse gas emission inventories." https://pubmed.ncbi.nlm.nih.gov/26997421/

'tall legs' require more steel and concrete, and more cost, with a resultant higher build-out emissions.

SMRs (small modular reactors) are the solution.

Depends upon conditions. EVs are stealthy, but heavier. EVs can control each individual wheel which improves traction. New graphene batteries will greatly extend range over current LiOn batteries. And hopefully batteries will be swappable in the field.

Incorporate Coil Driver and watch the EVs outperform the ICE vehicles while also reducing overall vehicle weight.

You're not paying attention if you think Putin waved the white flag. He's a pathological liar who still won't relinquish claiming the five oblasts in Ukraine. Reagan would have fully supported Ukraine, and it's a small price to pay to help Ukraine dismantle the false Russian military superiority image they've perpetrated for 70+ years.

In my ecopolitical thriller novel, The Carbon Trap, geneticists modify some species (including a phytoplankton) to increase CO2 absorption and, when dying, NOT be recycled into the ocean ecosystem, thus decreasing atmospheric CO2. Of course, it gets out of control and threatens all life on Earth.

What if you incorporated diffused platelet graphene into the cement? Likely you could further reduce carbon, weight, and overall cost. https://firstgraphene.net/a...

Incorporate Exro's Coil Driver and the Bushmaster will have a longer range, higher torque, faster speed, and be lighter. Switch over to upcoming G+Al batteries and the range will be greatly extended and you won't be enriching China via their LiOn batteries.

Re: Rolls-Royce enters hydrogen production market

Randy Dutton — Wed, 20 Jul 2022 14:19:01 -0000

"Recently it's been found that the hydrogen economy will also increase global warming because free-hydrogen reacts with the hydroxyls (-0H) that otherwise would react with CH4 and some other GW gases. Thus, hydrogen is now rated as 11 times worse than CO2, and hydrogen is very difficult to contain, having a high leakage rate. "...a new UK Government study has determined that hydrogen's Global Warming Potential (GWP) is about twice as bad as previously understood; over a 100-year time period, a tonne of hydrogen in the atmosphere will warm the Earth some 11 times more than a tonne of CO2, with an uncertainty of ± 5." https://newatlas.com/enviro...

Critical point missing from the article. Free hydrogen is 11X more damaging to global warming than CO2 because hydrogen reacts with -OH hydroxyls that otherwise would remove methane and N2O.

Re: What you should know if you get covid on a Royal Caribbean cruise ship

Randy Dutton — Thu, 07 Jul 2022 12:17:36 -0000

Our experience was quite different. As a family of four in two staterooms, we embarked on the RC Voyager of the Seas 26 June 2022 on a Baltic cruise. We all had tested negative on the antigen test within 24 hours before boarding, but on day 2, one of my adult children was tested by RC medical, which decided AFTER the sailing, that his submitted Vax card photo didn't show his more recent booster shot. So they tested him and this time he tested positive on both the antigen and PCR. Next thing we knew, he 'disappeared', with a letter left in his cabin saying he and his luggage had been moved to medical. No one in the RC staff bothered to tell us, his parents, where he had been taken or how to contact him. I was the primary account holder and one would think RC would tell us, then or at some time in the remaining 5 days of the cruise. Nope. I found my son by calling Customer Service and tracking down his telephone number, which then became the only means of checking his welfare. His brother, who shared the stateroom, was tested and was negative, but had to wear a mask and not eat in the dining room. My afflicted son did not get any medical care by RC staff, got no means for sunlight or physical activity, and his food almost always was cold. Of all the RC staff, only the dining room waiter expressed concern for our son, and it was fortunate that he was one of the staff delivering food to our 'Covid jailed' son. We implored the waiter to ensure the food was hot, and to additionally provide a basket of fruit, and another of bread. Our son was put on the pier BEFORE even all the mooring lines were tight. No options were given for hotels, airfare changing fees, per diem, etc. as mentioned in the original blog. Not once did any RC administrative staff talk to us. Oh, and when I went to the front desk to find where my son had been taken, and why RC didn't convey BEFORE the cruise, that his submitted paperwork wasn't current enough when we could have rectified the issue, the staff said it wasn't their responsibility.

I would add, that our afflicted son was the only one of us four who had not gotten a booster shot in the month prior to the cruise ... as I had asked him to do. He got Covid, the rest of us did not, or at least, our viral load was too low for the antigen testing to pick up. For the most part, he was asymptomatic the entire time.

So glad to see some commonsense finally considered. 45 seconds is enough for many to grab what then need, turn off gas or electricity, grab their cell phone, open the garage door and get the car out, or just get onto the front lawn. Along the coast a tsunami could be racing forward, and if several minutes of the 15 are spend under furniture, that's less time to get to high ground.

Re: These were the top 5 biggest electric bike news stories of 2021

Randy Dutton — Mon, 20 Dec 2021 13:47:33 -0000

For 2022: 1. Coil Driver electronic motor switching will provide more torque, climability, speed, and range to eBikes (see EXROF at 2022 CES show)
2. And new Graphene Aluminum batteries will start replacing LiOn batteries because they're safer, 70X faster charging, have higher power density, last 3X longer, can deep discharge without damage; are recyclable; don't require rare earth elements, lithium, or other exotic materials. (See GMGMF).
