Each 1 Degree C We Warm the Planet adds an additional 7% Increase in Moisture into the Atmosphere.

For every 1 degree C we increase the temperature on the planet we see 7% more moisture in the atmosphere. We are heading to and beyond the IPCC worst case scenario of  6C minimum which will generate another 40% of moisture in the air. This will lead to a greater number of flooding events and increased number of lightning strikes and Tornadoes.
This is an enormous amount of energy and associated warming as water vapour is in itself a green house gas.


The impact of climate change may be worse than previously thought, a new study suggests”:  As world leaders hold climate talks in Paris, research shows that land surface temperatures may rise by an average of almost 8C by 2100, if significant efforts are not made to counteract climate change.”

Personally I disagree with the suggestion that it will take until the magic 2100 for our locked in 8C temperature rise. Factor in the myriad of feedback loops and we could be there in a few decades,not that humans will survive that long to bare witness.

Such a rise would have a devastating impact on life on Earth:  ‘Climate Outlook May be Worse than Feared.’

The amount of water vapor in the atmosphere exists in direct relation to the temperature. If you increase the temperature, more water evaporates and becomes vapor, and vice versa. So when something else causes a temperature increase (such as extra CO2 from fossil fuels), more water evaporates. Then, since water vapor is a green house gas, this additional water vapor causes the temperature to go up even further—a positive feedback.”

Explaining how the Water Vapor Greenhouse effect works; Sceptical Science.

How much does water vapor amplify CO2 warming? Studies show that water vapor feed back roughly doubles the amount of warming caused by CO2. So if there is a 1°C change caused by CO2, the water vapor will cause the temperature to go up another 1°C. When other feedback loops are included, the total warming from a potential 1°C change caused by CO2 is, in reality, as much as 3°C.

“A warmer atmosphere can hold more moisture, and globally water vapour increases by 7% for every degree centigrade of warming.”

Excellent article and Q & A from The Guardian below:  ‘How Will Climate Change Affect Rainfall?

I'm an anti-imperialist, environmental activist and blue ocean sailor, who is passionate about the earth and all it's inhabitants without favour. Brace for imminent impact as we bare witness to the non-linear unraveling of the biosphere and habitability disappearing for most if not all complex life on the only habitable planet we know of. To quote President Niinistö in North Russia: ‘If We Lose the Arctic, We Lose the World’. Folks we have lost the Arctic.

    More than a years rain in two hours kill 22 and and injures 60 in Macedonia.


  2. Kevin Hester says:

    “It’s worth noting, however, that NOAA model runs have often not captured the full potential peak rainfall totals in some recent severe events. ”
    I reiterate for the hundredth time that the models are always understating the severity and pace of the crisis.

    MOSCOW (AFP) –
    Torrential rains in Moscow on Monday beat a 129-year-old record for the heaviest August downpours, the state weather service said.
    Muscovites splashed through flooded streets after more than 48 millimetres (1.9 inches) of rainfall hit the city, authorities said, nearly double the previous maximum recorded back in 1887.
    “This is a new historical record for mid-August,” the meteorological centre said in a statement.
    “The last record of 25.2 millimetres of precipitation was recorded in 1887.”
    The downpour saw a tributary of the Moskva River break its banks in northeastern Moscow and flooded at least one station in the city’s sprawling subway system.


  4. Kevin Hester says:

    “An incomprehensible amount of rain is falling from the sky over the Carolinas. Radar data suggests a rainfall rate of three to four inches per hour in some locations. Nearly 10 inches of rain has already fallen and the region still has hours to go in this storm.”

    “This might end up being the biggest disaster that Hurricane Matthew unleashes on the Southeast.”

    Torrential rain in Alice Springs of all places too.

    “Meanwhile, Cyclone Cook, similarly engorged with moisture, is in the process of combining with a large trough extending down from the Southern Ocean and over New Zealand. Cook is predicted to track toward New Zealand across ocean waters that are 1-2 C warmer than normal over the next few days. It is expected to feed energy into a long frontal system extending up from the ocean region just north of Antarctica. Present model predictions indicate the potential for extremely high cloud moisture loading in the range of 3.5 kilograms of water per square meter over parts of North Island near Tauranga in the 26-30 hour time-frame. A worrisome potential extreme precipitation hot spot in a mated system that is expected to again blanket New Zealand with flooding rains over the next three days.”

    It is precipitating down in California! Another day, another record.

    “Imagery of the cloud swath stretched across the entire Pacific, along which these rivers are flowing, has stunned meteorologists.”

    “Talk about an atmospheric river!! Wow!” exclaimed the National Weather Service office serving Portland, Ore., in a tweet.”



  10. Now that I’m not on dial-up for the first time since my shop went online in 1998, I can actually HEAR Guy’s voice. Boy does he not sound happy… Rather resigned I think is the word I’m looking for.

    Raining on Greenland. Boiling and burning here along the Canadian Border. Rain ‘events’ going off everywhere, tropical cyclones and Atlantic hurricanes. What evaporates up definitely must come down…but with local weather here only in the 80s this last week there is (hopefully) rain predicted tomorrow through the weekend. That is sorely needed in this forest as conifer needles continue to brown in clumps everywhere I look. So far we haven’t had one of these monster downpours being seen elsewhere.

    Yep, Guy, you most certainly will keep seeing weirder weather nailing our species to the wall as the future unfolds itself on our ignorant heads. You were correct years ago in your thinking that it’s all going to happen so much quicker than expectations. Which, to be honest, I’m assuming isn’t much of a consolation prize for the slime you’ve been splattered with over the years.

    Big sigh. I read a description recently: humans are killer apes with a tinge of rabid wolf thrown in… Fair accurate, that.

Kevin Hester is currently living on Rakino Island, a small island in the Hauraki Gulf near Auckland, New Zealand, monitoring the unravelling of the biosphere and volunteering at the Rakino Island Nursery is currently developing a proposal to create a marine reserve near by. The Island has no grid tied electricity or reticulated water.  I catch my own water from the roof and generate my electricity from the ample solar radiation on the island.
