Landmark UN Climate Change Report: Act Now To Avoid Climate Catastrophe | IFLScience

https://www.iflscience.com/environment/landmark-un-climate-change-report-act-now-to-avoid-climate-catastrophe/

The Intergovernmental Panel on Climate Change (IPCC) has unleashed their Special Report on the impact of global warming reaching 1.5°C above pre-industrial levels.
“This IPCC report is set to outline a rescue plan for humanity,”
“1.5°C is the new 2°C,”
If we stick to Paris Climate Agreement commitments, we could still see a global warming of about 3°C by 2100.

    Effects of battery manufacturing on electric vehicle life-cycle greenhouse gas emissions
    https://www.theicct.org/publications/EV-battery-manufacturing-emissions

    This briefing reviews recent research regarding greenhouse gas emissions from the manufacturing of lithium-ion batteries for electric vehicles. We analyze this research in the overall context of life-cycle emissions of electric cars as compared to conventional internal combustion vehicles in Europe.

    Electric cars are much cleaner than internal combustion engine cars over their lifetime. We find that a typical electric car today produces just half of the greenhouse gas emissions of an average European passenger car. Furthermore, an electric car using average European electricity is almost 30% cleaner over its life cycle compared to even the most efficient internal combustion engine vehicle on the market today. Plug-in hybrid vehicles, when driven on electric power for most trips, have lifecycle emissions similar to battery electric vehicles. In markets with very low-carbon electricity, such as Norway or France, electric vehicles produce less than a third of the life-cycle emissions of an average combustion-engine vehicle.

    Truth is the First Casualty of Global Warming
    Dec 18, 2018 BJØRN LOMBORG

    The truth about climate change is nuanced: it is real, and in the long term it will be a problem, but its impact is less than we might believe. And yet we are too eager to believe the problem is far worse than science shows, and – conversely – that our solutions are far easier than reality dictates.

    limate change seems to freeze our capacity for critical thinking: we are too eager to believe the problem is far worse than science shows, and – conversely – that our solutions are far easier than reality dictates.

    Consider weather events: it is second nature now to link these to climate change. Whenever a flood hits, the media blames global warming and warns that floods are increasing.

    Both European forest fires and US hurricanes are blamed on global warming.

    The truth about climate change is nuanced: it is real, and in the long term it will be a problem, but its impact is less than we might believe. According to the IPCC’s last major report, unrestrained climate change would result in an average reduction in income of about 0.2-2% by the 2070s. That is equivalent to the impact of a single economic recession over the next half-century.

    Yet, in a race to the bottom with climate-change deniers, green activists have become hyperbolic. Influential campaigner George Monbiot says “climate change” isn’t alarming enough, so should be replaced with “climate breakdown.”

    Climate is not breaking down.

    Just as activists and the media engender fear by associating every fire, flood, and hurricane with climate change, they generate a false belief that there are simple solutions to the problem, if only politicians and the public would embrace them.

    Take the new argument that becoming vegetarian could fix climate change. The reality is that a Westerner abandoning all meat will cut her greenhouse-gas emissions by only a few percentage points.

    Another common refrain is that solar and wind are ready to outcompete fossil fuels. But alternative energy remains reliant on subsidies to the tune of $160 billion annually. When these are withdrawn, investments in solar and wind typically plummet.

    Globally, solar and wind satisfy less than 1% of our energy needs.

    tackling global warming – like everything else – is a question of finding the right balance

    It would cost about $20 trillion to avoid some climate damages, ensuring a net benefit of $30 trillion over coming centuries.

    to within 2.5°C of preindustrial levels, would drive the cost beyond $130 trillion, leaving us $50 trillion worse off.

    Contrast Nordhaus’s careful work showing that a 2.5°C cap is near impossible, with the excitement being whipped up about keeping the rise in global temperature below the much harder 1.5°C threshold. At current emissions levels, this would require us to end fossil-fuel use in ten years

    The IEA expects that fossil fuels will still meet three-quarters of global energy demand by 2040.

    Fast Trains Are Energy Efficient (And Fast)
    https://spectrum.ieee.org/transportation/mass-transit/fast-trains-are-energy-efficient-and-fast

    Energy intensity is the key. When I’m the only passenger in my Civic, it requires about 2 megajoules per passenger-kilometer in city driving. Add another passenger and that figure drops to 1 MJ/pkm, comparable to a half-empty bus. Jet airliners are surprisingly efficient, commonly requiring around 2 MJ/pkm. With full flights and the latest airplane designs, they can do it at less than 1.5 MJ/pkm. Of course, public-transit trains are far superior: At high passenger loads, the best subways need less than 0.1 MJ/pkm.

    This Incredible Powder Could Help Cut CO2 Emissions
    https://www.iflscience.com/environment/this-incredible-powder-could-help-cut-co2-emissions/

    With the clock ticking to avoid climate catastrophe, every action is important to reduce the amount of carbon dioxide that we release into the atmosphere.

    The scientists developed an extremely porous carbon powder that can capture a large amount of the greenhouse gas. The powder is made of carbon nanospheres

    Carbon dioxide molecules adhere to the surface of the nanospheres

    Once filled with carbon dioxide, the powder would be taken to storage sites and buried, which would have no adverse consequences. Carbon is both abundant and environmentally friendly so this is a great strategic material to use in greenhouse-gas-capturing initiatives.

    Climate Change is Pushing Electrical Engineers to Focus on the Environment
    https://www.eeweb.com/profile/janesandwood/articles/climate-change-is-pushing-electrical-engineers-to-focus-on-the-environment

    Electrical engineers are working with water treatment facilities to help optimize their systems and processes to save time, money, and resources

    Electricity generation is a lead contributor to carbon dioxide emissions that affect the environment; in fact, it is expected to be responsible for 76% of total emissions by 2035.

    Energy consumption of water treatment facilities
    Wastewater systems account for approximately 3% to 4% of energy use in the United States and result in the emission of more than 45 million tons of greenhouse gasses (GHGs) annually.

    A recently released document by the U.S. Environmental Protection Agency noted that saving energy through energy-efficiency improvements can cost less than generating, transmitting, and distributing energy from power plants in order to treat the water. The EPA went on to suggest that wastewater facilities can possibly begin to install anaerobic digesters that generate methane, which can then be burned on-site to power the facility.

    Plugging holes in the water system
    As water treatment facilities play a crucial role in the overall health and safety of millions of people around the world, engineers have an opportunity to enter the discussion before it is too late.

    Do the math on replacing fossil fuels: To move fast enough, the world needs to build lots of reactors

    Climate scientists tell us that the world must drastically cut its fossil fuel use in the next 30 years to stave off a potentially catastrophic tipping point for the planet. Confronting this challenge is a moral issue, but it’s also a math problem—and a big part of the solution has to be nuclear power.

    Today, more than 80% of the world’s energy comes from fossil fuels

    Ranskalaisen klimatologin kehotus tiedemiehille: ottakaa etäisyyttä IPCC:hen

    To date, definitive answers to questions about ultimate causes and effects of global warming remain elusive. In Global Warming – Myth or Reality? . Marcel Leroux seeks to separate fact from fiction and lays out the scientific cause of the sizable sceptical scientific community that challenges the accepted wisdom.

    Lreoux takes a hard and dispassionate look at the reality of the greenhouse effect, the “evidence” from climate models, and the limitations of those models. He then postulates alternative causes of climate change and analyses the trends for global temperatures, rainfall patterns, dynmaics of weather and sea level. He argues that the case for global warming is based on climatology which, with its insufficiencies in the understanding and explanation of weather phenomena do not support this prediction. Leroux highlights a number of priorities that climatologists could consider in order to understand the processes of climate change, integrate them into deterministic climate models, and predict accurately changes of climate of the near future. The most urgent priority for climatology, the author believes , is to leave the IPCC in order that the discipline remains neutral and returns to the pursuit of its proper ends.

    We Can (Maybe) Avoid Climate Change Catastrophe, Says Big New Report
    https://www.iflscience.com/environment/we-can-maybe-avoid-climate-change-catastrophe-says-big-new-report/

    Hope is not lost when it comes to the colossal problem of climate change. According to a massive new report, it is possible to avoid catastrophic levels of climate change, however, it’s going to require some sturdy and immediate action.

    The new research, published in the journal Nature Communications, puts forward a wealth of evidence to show how the world could limit the disastrous effects of climate change if we phase out current fossil fuel infrastructure at the end of its expected lifetime.

    By their workings, if we allow the current generation of fossil fuel infrastructure – such as power plants, industrial facilities, petrol vehicles, and the like – to run their course, then promptly replace them with zero-carbon alternatives, there is a 64 percent chance of keeping global warming below 1.5°C (2.7°F) above pre-industrial levels.

    At the Intergovernmental Panel on Climate Change (IPCC) meeting in October 2018, the world agreed that the rise in global temperatures must be kept below 1.5°C (2.7°F) above pre-industrial levels, otherwise, it will spark cataclysmic changes to our world.

    Make no mistake, this objective will be hard to achieve, but it’s not impossible.

    Greenland’s Ice Is Melting Far Faster Than Thought, And It May Be Too Late To Act
    https://www.iflscience.com/environment/greenlands-ice-is-melting-far-faster-than-thought-and-it-may-be-too-late-to-act/

    Just a few weeks ago, a major report found that Antartica is losing six times as much ice each year than 40 years ago. It turns out, the situation isn’t much better in the farthest stretches of the northern hemisphere either.

    New research has shown that Greenland’s ice is melting far faster than scientists previously thought and could become a major contributor to sea level rise around the world within just two decades.

    Worse of all, it looks like it’s too late to do anything about it.

    “The only thing we can do is adapt and mitigate further global warming – it’s too late for there to be no effect,”

    “These oscillations have been happening forever,” Bevis added. “So why only now are they causing this massive melt? It’s because the atmosphere is, at its baseline, warmer. The transient warming driven by the North Atlantic Oscillation was riding on top of more sustained, global warming.”

    This Dutch Startup Converts Heat Into Cold Via A Stirling Engine, And Could Just Save The Planet

    By 2050, almost six billion air conditioners could eat 37% of global electricity, according to the International Energy Agency. That’s because as India and China get richer — and the planet gets hotter — people around the globe are buying A/C units at levels approaching the United States.

    This is an environmental catastrophe waiting to happen.

    change that via a technological marvel that turns heat into cold without requiring energy itself — or any of the nasty gases that most A/C units use today. The technology, which SoundEnergy unveiled at CES last week in Las Vegas, uses a process similar to a Stirling Engine

    SoundEnergy’s first customer was Dubai, which purchased a unit for cooling in a plant which condenses drinkable water from the air.

    Warming seas may increase frequency of extreme storms
    https://climate.nasa.gov/news/2837/warming-seas-may-increase-frequency-of-extreme-storms/

    A new NASA study shows that warming of the tropical oceans due to climate change could lead to a substantial increase in the frequency of extreme rain storms by the end of the century

    They found that extreme storms – those producing at least 0.12 inches (3 millimeters) of rain per hour over a 16-mile (25-kilometer) area – formed when the sea surface temperature was higher than about 82 degrees Fahrenheit (28 degrees Celsius). They also found that, based on the data, 21 percent more storms form for every 1.8 degrees Fahrenheit (1 degree Celsius) that ocean surface temperatures rise.

    Ice-core records show that climate changes in the past have been large, rapid, and synchronous over broad areas extending into low latitudes, with less variability over historical times. These ice-core records come from high mountain glaciers and the polar regions, including small ice caps and the large ice sheets of Greenland and Antarctica.

    Bottom line truth is they just don’t know enough to determine what, how, and at what rate climate change is happening or will continue to happen.

    Greenhouse gasses causing trapped heat? Possibly, maybe even probably.

    Decreased sun activity causing cooling? Possibly, maybe even probably.

    The cool thing about modeling is that in events like climate change you can make a super minor tweak to any of the postulate assumptions and get any result you want.

    We still have a lot to learn

    The sun may be dimming, temporarily. Don’t panic; Earth is not going to freeze over. But will the resulting cooling put a dent in the global warming trend?

    A periodic solar event called a “grand minimum” could overtake the sun perhaps as soon as 2020 and lasting through 2070, resulting in diminished magnetism, infrequent sunspot production and less ultraviolet (UV) radiation reaching Earth — all bringing a cooler period to the planet that may span 50 years.
