    The mission is maintaining our sovereignty not climate change.
    They do a little weather modification from time to time. Boom.
    Weather is 9° in New Mexico with blizzard warnings but if it's a heat wave in New Mexico then it's not weather but a climate crisis that can only be fixed by surrendering your freedom and prosperity to tyranny?
    No deal.
    Stay warm.

    The existing energy system, that some of you so passionately defend, has its own share of often-ignored problems. Time to grow up, boys, or get left behind. Your choice.

    'Invisible killer': fossil fuels caused 8.7m deaths globally in 2018, research finds
    • Air pollution caused by the burning of fossil fuels was responsible for 8.7m deaths globally in 2018
    • That is one in five of all people who died that year
    • One in 10 deaths in both the US and Europe were caused by the resulting pollution
    • And nearly a third of deaths in eastern Asia
    • The death toll exceeds the number of people who die each year from smoking tobacco plus malaria

    The study was published in Environmental Research

    There is so much wrong with that article, In surprised someone as intelligent and learned as you, IN, would show it to us, except to laugh at it.
    I don't have time, right now to go into its problems, but...
    "Scientists have established links between pervasive air pollution from burning fossil fuels and cases of heart disease, respiratory ailments and even the loss of eyesight. Without fossil fuel emissions, the average life expectancy of the world’s population would increase by more than a year, while global economic and health costs would fall by about $2.9tn."
    People's average life span has increased significantly since industrialisation.

    Fossil fuels saved 100's of millions of people during that same period of time, who would have surely perished without the ability to heat their homes, their food, light their way, communicate by radio, sterilize their surgical instruments, arrive at fires and accident scenes, centrifuge blood samples and grow food.

    It is not new information that atmospherically suspended paticulate matter lowers temperatures on the surface of the Earth below.
    More record cold is projected to hit us in early March.
    It brings this to mind:
    Year Without a Summer - Wikipedia https://en.m.wikipedia.org/wiki/Year_Without_a_Summer

    "These eruptions had built up a substantial amount of atmospheric dust. As is common after a massive volcanic eruption, temperatures fell worldwide because less sunlight passed through the stratosphere."

    It begins with diesel fuel, which has an exceptional quality. It is not generally known but gallon for gallon and dollar for dollar, diesel fuel is the absolute best source of stored energy available. It is safe to handle and cheap to manufacture. It is the ideal fuel for the load-hauling industry.

    For example, one gallon of diesel fuel stores 38 kilowatt hours of energy. Diesel has 113% the energy density of gasoline and 140% the energy density of propane. It has 27 times the energy density of lithium ion batteries. Diesel fuel weighs only 6 lbs./gallon and that single gallon stores 38 kilowatt (kwh) hours of energy. Diesel stores over 6 kwh of energy per pound. In the Wikipedia table below, lithium ion batteries scored dead last in energy density and diesel scores first, among fuels.

    While I am flattered that you hold my intelligence in high esteem, I hope that you can find time between your snorkeling and sunbathing sessions to amplify your response.
    I don't understand why you think Statement 1 and Statement 2 are mutually exclusive. To my way of thinking, the use of fossil fuels has greatly contributed to our standard of living, but their use also comes with drawbacks. CO2 emissions is one; air pollution is another.

    I agree with you that diesel fuel, along with jet fuel, and bunker fuel, have very high energy densities. And I agree with you that they will be hard to replace. But the writing is on the wall, and innovative companies are exploring other options.

    Kenworth Launches K270E and K370E Electric Trucks
    Kenworth announced that its first two all-electric trucks, the Class 6 K270E (shown at 2020 CES) and Class 7 K370E are now available for orders in the U.S. and Canada.

    The trucks, equipped with Dana tech, are offered with two battery options - 141 kWh or 282 kWh - for two ranges - 100 miles (160 km) or 200 miles (320 km).

    For charging, the manufacturer envisioned DC fast charging (J1772 combo aka CCS Combo 1) in one hour or overnight AC charging.

    There are also two electric motor options: 355 hp or 469 hp, so customers will be able to configure the right solution for their needs. According to the manufacturer, the trucks are able to start the load from a stop on a 20 percent grade and have the power to maintain 40 mph on a 6 percent grade while fully loaded.

    There are also three wheelbase options: 206 inches (24-foot box bodies), 218 inches (26-foot box bodies) and 274 inches (30-foot box bodies).

    The first electric trucks from Kenworth to be delivered to customers before the end of 2020.​

    Tesla Semi
    Acceleration 0-60 mph with 80k lb -- 20 sec
    Speed up a 5% Grade -- 60 mph
    Mile Range -- 300 or 500 miles
    Powertrain -- 4 Independent Motors on Rear Axles
    Energy Consumption -- Less than 2 kWh per mile
    Drag coefficient -- 0.36
    Fuel Savings -- $200,000+
    Expected Base Price (300 mile range) -- $150,000
    Expected Base Price (500 mile range) -- $180,000
    Base Reservation -- $20,000

    United Airlines Carbon neutral by 2050
    We recognize the role we play as an airline in contributing to climate change and therefore our responsibility in solving it. To meet our goal of going 100% green by reducing 100% of our greenhouse gas emissions by 2050, we want to lead our industry toward real solutions and lasting change.

    Our path to decarbonization
    True sustainability is about taking on the biggest culprit in our industry — the emissions generated by our aircraft. Unlike other airlines, we’re looking beyond using carbon offsets. We believe carbon offsets simply don’t go far enough to address the emissions caused by our operations. To achieve carbon neutrality by 2050, we’ll aim to tackle emissions at their source by continuing and accelerating development and investment in:

    Sustainable fuel
    Sustainable fuel is made from renewable resources and waste byproducts — and sustainable fuel has up to 80% fewer carbon emissions than conventional jet fuel, making it the fastest and most effective way United is reducing its emissions across its fleet. We have been investing heavily in sustainable fuel for more than a decade now, using half the world’s committed volumes alone.

    Direct Air Capture

    Carbon capture and sequestration has been widely viewed by scientists as a necessary step to limit climate change and one of the most scalable options is Direct Air Capture technology. We intend to make a multimillion-dollar investment in a startup that will help fund the first Direct Air Capture plant in the U.S. A Direct Air Capture plant is planned to capture, remove and store 1 million metric tons of CO2 — which is like the work of 40 million trees.


    Retrofit highlights use of LPG as a marine fuel

    The world’s first LPG-fuelled vessel successfully set sail in October 2020. Powered with Wärtsilä’s customised and reliable Fuel Supply System, the vessel represents a major breakthrough in the search for new ways to reduce marine emissions.

    G.M. Will Sell Only Zero-Emission Vehicles by 2035

    The move, one of the most ambitious in the auto industry, is a piece of a broader plan by the company to become carbon neutral by 2040.

    Good luck. I'd love to see batteries thirty seven times more energy capacity than the best present technology offers. Good for my boats, but I doubt I'll see it in my lifetime, and I expect to live a long time. At least to a hundred.end of 2048.

    The writing is on the wall? Well you know walls can be torn down and what then becomes of the writing? It goes the way of fallen wind generators.
    Batteries don't work in subzero temperatures.
    Advice: Don't get between us and our fossil based heating fuels. More wars start during cold years than warm ones.

    Some people prefer to look backwards rather than forwards, and then wonder why they keep bumping their heads. <laugh>

    Some people prefer to freeze to death in their battery heated homes.
