    Since electric cells are limited to low voltage, multiple cells in series are used for more powerful batteries. your telve volt car battery is a multi-cell battery.

    could painting alternating stripes of hydrophobic and hydrophilic coatings on a boat hull, result in a multi-cell battery?

    Busy Atlantic hurricane season predicted for 2020

    May 21, 2020 An above-normal 2020 Atlantic hurricane season is expected, according to forecasters with NOAA’s Climate Prediction Center, a division of the National Weather Service. The outlook predicts a 60% chance of an above-normal season, a 30% chance of a near-normal season and only a 10% chance of a below-normal season. The Atlantic hurricane season runs from June 1 through November 30.

    NOAA’s Climate Prediction Center is forecasting a likely range of 13 to 19 named storms (winds of 39 mph or higher), of which 6 to 10 could become hurricanes (winds of 74 mph or higher), including 3 to 6 major hurricanes (category 3, 4 or 5; with winds of 111 mph or higher). NOAA provides these ranges with a 70% confidence. An average hurricane season produces 12 named storms, of which 6 become hurricanes, including 3 major hurricanes.

    The combination of several climate factors is driving the strong likelihood for above-normal activity in the Atlantic this year. El Nino Southern Oscillation (ENSO) conditions are expected to either remain neutral or to trend toward La Nina, meaning there will not be an El Nino present to suppress hurricane activity. Also, warmer-than-average sea surface temperatures in the tropical Atlantic Ocean and Caribbean Sea, coupled with reduced vertical wind shear, weaker tropical Atlantic trade winds, and an enhanced west African monsoon all increase the likelihood for an above-normal Atlantic hurricane season. Similar conditions have been producing more active seasons since the current high-activity era began in 1995.

    NOAA believes its hurricane season forecasts to be about 70% accurate, he added. Scientists say that global warming is making hurricanes more deadly- in part because warmer air can hold more water.May 23, 2019

    Forecasts today can get hurricane tracks wrong by hundreds of miles and wind speeds by tens of miles per hour. As a result, Majumdar says, "people often return after an evacuation to find nothing really happened." The solution, he says, is to improve forecasting through better science.Apr 25, 2020

    Are AGW forecasts of future climate better or worse than 70% accurate? Guess we'll find out, won't we.

    of course simply flipping a coin augurs 50% accuracy

    We view the world and events through the lenses of bias. Bias can also be defined as a dearly held premise. You tend to see what you want to see. even if the premise is false and your eyes deluded.by your expectations. what is the underlying premise of AGW?

    The initial premise is humans MUST be influencing climate.

    What happens to the premise humans Must, if humans COULDN'T?
    That's my own premise. We're tiny, the world is huge and the human contribution to CO2 is .0016 of one percent. Not significant.
    Of course, those who believe fervently are outraged i dismiss their cherished beliefs so cavalierly. Okay, it's okay to be offended!

    Not all credible scientists agree with AGW

    Are facts determined by a majority or a consensus? Of course not. is the majority more often than not, at least on the right track? NO!

    Study shows wetter climate is likely to intensify climate change

    A new study published in the journal Nature indicates that the increase in rainfall forecast by global climate models is likely to hasten the release of carbon dioxide from tropical soils. That release would further intensify global warming by adding emissions of the greenhouse gas into Earth's atmosphere.

    "We found that shifts toward a warmer and wetter climate in the drainage basin of the Ganges and Brahmaputra rivers over the last 18,000 years enhanced rates of soil respiration and decreased stocks of soil carbon," says Hein. "This has direct implications for Earth's future, as climate change is likely to increase rainfall in tropical regions, further accelerating respiration of soil carbon and adding even more CO2 to the atmosphere than that directly added by humans."

    Thank goodness we can all relax. Global warming causes rain and now it's discovered rain causes release of CO2 into the atmosphere. Dovetails nicely with ice core records. Warming precipitates , leads, causes increases in CO2. We are fortunate there appears no real evidence CO2 causes global warming.
    otherwise we'd have a self sustaining, self perpetuating, self aggrandizing cycle that could snowball into a fireball!

    Rivers flowing into the sky?
    The magnitude of the water that goes into the sky from irrigation and landscaping is enormous. The Colorado River which used to flow into the Gulf of California but is now so diminished that it disappears into the desert carries more gallons of water than all the gallons of gasoline consumed throughout the U.S. An average annual flow rate for the Colorado River upstream is about 10,000 cubic feet per second. That translates into 864 million cubic feet per day, which is about 6.5 billion gallons per day. The total gasoline usage in the U.S. amounts to 378 million gallons per day, only about 6 percent of the disappearance of water from the Colorado.

    Though they don't talk about feedback loops very much now (embarrassed I imagine) AGWers basically ignore water vapor as the prime mover greenhouse gas. Instead they myopically concentrate on CO2.

    Why?

    As I pointed out earlier, as credible scientists Like Dr. Curry have pointed out, the premise that humans are causing warming pre-existed any evidence. Treaties were signed between some member nations of the UN prior to there being supporting evidence. Then the UN created committees to investigate. Were they investigating causes of global warming?
    NO!
    Their mission was to find evidence HUMANS caused global warming.

    Water vapor doesn't fit in with their agenda, so they accord tiny CO2 the credit for the entire warming. Of course, they also ignore that total human produced CO2 is insignificantly minuscule, about 12 ppm compared to the 400ppm of CO2 in the atmosphere.

    Water vapor produces 95% of warming. If governments could determine a way to tax it, they would be interested in water vapor. Meanwhile CO2 and fossil fuels are where governments steer their scientists.

    Yes! They are STEERED to CO2!

    So, the majority used to believe in a flat earth and that the sun revolved around the earth, and many more ignorant things we have outgrown. I know the earth is an oblate spheroid. I have navigated around it using spherical trigonometry. Are you claiming YOU are a flat earther?
