Greenhouse Gas Levels Hit a New High In 2020, Even With Pandemic Lockdowns (npr.org) 159

Despite a world economy that slowed significantly because of COVID-19, the accumulation of greenhouse gases in the atmosphere reached a new record last year, putting the goal of slowing the rise of global temperatures "way off track," according to the World Meteorological Organization (WMO). NPR reports: The United Nations body said Monday that carbon dioxide had risen by more than the 10-year average in 2020 to 413.2 parts per million, despite a slight decrease in emissions due to the coronavirus pandemic. Methane and nitrous oxide, two other potent greenhouse gases, also showed increases, the WMO said in the latest issue of its Greenhouse Gas Bulletin. "At the current rate of increase in greenhouse gas concentrations, we will see a temperature increase by the end of this century far in excess of the Paris Agreement targets of 1.5 to 2 C above preindustrial levels," WMO Secretary-General Petteri Taalas said. "We are way off track," he said.

Taalas said the last time the Earth had a comparable level of carbon dioxide in the atmosphere was 3 million to 5 million years ago, when the average global temperature was 2 to 3 Celsius hotter and the sea level was 10 to 20 meters (32 to 65 feet) higher than today. The WMO says that only half of human-emitted carbon dioxide is absorbed by oceans and land ecosystems. The other half remains in the atmosphere, and the overall amount in the air is sensitive to climate and land-use changes. Because carbon emissions increased in the last decade, even though there was a decrease last year due to reduced economic activity, atmospheric levels continued to increase progressively from the accumulation.

        I'm going to be modded down again [slashdot.org] by slashdots techno-romantic fission fans for bugging them with basic math, but nuclear fission as we know it isn't cost-effective. It only works if it is cross-funded by large amounts of tax payers money. And that's without pricing in the risk and an epic long-term waste problem we haven't solved yet(!). Given, feasibility of nuke-fission may change once energy prices rise and we can build TW or liquid salt reactors or some other fancy thing, but until that sort of thing is ready, nuclear fission isn't an option. That's a real shame and I wish it were different but that's the cold hard truth.

        I totally get that some people want to try out new fission reactor types and they should get the support they need to do that if the math has a chance of working out. Until then wind and solar and saving energy is the way to go. We'll have to do it anyway because uranium is a limited fossil fuel itself. Let's fill the deserts with solar panels and get this change going. That's a very neat long-term solution right there. It's also Elon Musks prime strategy for solving the energy crisis and he is the smart guy that makes things happen, so I actually do trust his math on solar.

The sawtooth pattern is due to the difference in northern and southern hemisphere foliage growth.

When the input goes down, the dependent variable (atmospheric concentration) turns downward immediately.

    Another Slashdot article about the problem of rising CO2 emissions without mention of solutions. We were told how to solve this problem, we only need to listen to the people that took the time to study what will work and what will not. We should probably listen to Dr. David MacKay, he was appointed Chief Scientific Advisor to the Department of Energy and Climate Change, he was a professor of physics and engineering, and knew a few things about how to process data. He told the UK government that they need to build nuclear fission power plants and sequester carbon. He told the government this in very simple arithmetic, and backing up his claims with real world data.

    I can hear it now, but what about the money it takes to build these nuclear fission power plants? And the time they take to build? Would not windmills and solar power be cheaper and easier? Dr. MacKay told the UK government that if they don't build nuclear power plants then they will fail to meet their energy needs and fail to lower CO2 emissions.

    I expect people to still protest. They will bring up concerns about weapon proliferation, radiation leaks, terrorists attacks on nuclear power plants. These do not factor in to the decision to use nuclear power or not because the UK needs nuclear power or they will not have the energy to sustain their economy.

    Still people will not get the message, they will talk of an intercontinental "smart grid", with windmills out in the North Atlantic, solar PV and solar thermal projects in North Africa, hydroelectric dams, pumped hydro storage, grid scale batteries, rooftop PV, "agri-voltaics", biomass fuels, and electric vehicles. Electric cars, electric planes, electric ferries, electric trains, electric farm and constriction equipment, electric mining trucks that make more energy than they consume by hauling materials down form the mountain top mine. They talk of storing energy as heat, compressed air, hydrogen, and weights that are spun or lifted. That might be helpful but it does not rid the UK of the need for nuclear power.

    If the UK does not produce nuclear fission power domestically then they will have to import it from nations like France, Spain, and Germany. There is no future in which the UK meets their energy supply needs without nuclear power. Because of the politics and economics of importing energy there will be a preference for this nuclear power to be produced domestically. Large undersea power cables into and out of the UK may for a while provide plenty of energy from wind and solar power into the UK but in time that flow of electricity will reverse. These North African nations will take on the wealth from selling energy to build schools, factories, homes, farms, hospitals, and more. These nations will find this energy more valuable to keep than sell. They will likely use this to produce products for export. This can be a varieties of foods, clothing, metals, fertilizers, synthesized fuels, carbon free steels and aluminum alloys. These nations will then become dependent on nuclear power from UK or have to develop the technology domestically.

    What Dr. David MacKay discovered was not just an energy plan for UK but for every nation on the planet. He showed that while some nations may not need nuclear fission power as desperately as UK they will need nuclear fission power. Some nations will need nuclear fission power far more than UK. Nuclear power will be part of a mix of energy sources. These nations will find wind power is optional. solar power is optional. Hydro power is optional. But nuclear fission power is not optional. Safe, sustainable, clean, low CO2, reliable energy means nuclear fission. Any objections to this only means that some issues will have to be addressed as nuclear power comes to these nations, not that they can be barred from having nuclear power. Some nations may need safeguards to prevent weaponizing the nuclear reactors. Denying them nuclear power means they will fail to meet the nation's energy needs and/or fail to meet the n

              When making steel, the big CO2 output is from smelting the ore. The ore is iron oxide, and you have to use chemistry to pull the oxygen off the iron. That usually involves heating iron ore with coke,

  • We've passed the tipping point and hit feedback loop, the planet is releasing it's own trapped greenhouse gasses. Gigantic methane reserves beneath the Siberian Tundra and at the bottom of the oceans have begun to belch into the atmosphere with the heat levels already achieved. Greatly reduced ice caps, warmer oceans, are already here. We now exceed 413 PPM C02. The last time the Earth exceed 400 ppm was Pliocene Era (between 5.3 million and 2.6 million years ago). At that time the Earth was 3 degrees
  • Just because you decided not to drive during the pandemic doesn't mean someone else didn't have to drive for you, to deliver the things you ordinarily would have gotten for yourself.
  • We have on record, even if they don't tell you, that China Russia and Saudi Arabia intend to cheat and increase both fossil fuel use and export at record levels, and that Australia will help them.

    The same goes for Canada - look at the internal announcements for pipelines and LNG exports in addition to tar sands (bitumen).

    All HEAVILY subsidized by taxpayers.

    All paying ZERO or close to zero taxes.

    The fix is in.

    They don't care that 80 percent of their own citizens disagree with these actions, they depend on th

  • For decades, the FUD crowd has been spouting off about how human activity is the cause of greenhouse gas emissions. Now, when there has been a lot less human activity, the gas levels are higher than ever. This just proves that correlation isn't causation and the climate is so much more complicated than any journalist or politician would have us believe. Beyond this, why is it that Americans have to fund other countries' climate change efforts? If Americans really cause the majority of greenhouse gas emi
