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.

    “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.”

    “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.”

  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.

    A spectacularly good article from Jennifer Francis who is my go to scientist specialising in the meandering jet streams. Her conservative perspective not withstanding.
    I’ve been writing about the water vapour feedback loop since 2016.
    This is a huge element in the climate system perilously ignored.


    • And more water is going to fall in every damn storm that blows in and more climate refugees are going to be piling up on the borders and… I’m thinking this is another very conservative outlook:

      By 2050, 200 Million Climate Refugees May Have Fled Their Homes. But International Laws Offer Them Little Protection

      Negotiators at COP26 are unlikely to deal with the challenges posed by climate migration, a failure that some experts say shows “a lack of political will.”



      Weather: more rain fell overnight and has mostly washed the thin snow covering of the last few days off except in very protected places under the conifer canopy. Ground is very wet and muddy because it is not freezing at night with the overcast keeping more daytime warmth trapped. The local ski hill snowcams are showing that it is likely raining at the lodge level and possibly even on the peak. I not only have ground fog with the rain at my 3,400 ft elevation but it’s warm enough to stand on the porch in a tee-shirt and be only a little chilled. Sure isn’t acting like mid-November here. Seems that increased rain and rain temperatures isn’t in the future…

    What a fascinating article, brilliantly ‘penned’.
    “But these are not usual days. As we write, late on Tuesday evening, officials say the pump station may soon be swamped with water,”
    I was involved in building a few pump stations. This one fails on being itself in the flood plane, not adjacent or above.
    Hardly any of the infrastructure is designed for what is falling out of the sky.



    • sealintheselkirks says:

      The Midwest of the US has been getting ‘gorilla hail’ which is the size of tennis balls, baseballs, and up to softball size. Derecho after windstorm after tornado after hail over and over again. And now it’s Hurricane season.

      It’s everywhere, Kev, as I’ve been watching weather reports from all over the world.

      I don’t watch corporate-owned MSM but somehow I doubt any talking head on any channel is connecting these worldwide dots for the general population. Wouldn’t want profit margins to fall by alarming people, eh?

      I’ve also been following the death of the Colorado River. Lake Mead on the Arizona/Nevada border is being drained to keep Lake Powell’s Glen Canyon Dam’s power generation operating. Flaming Gorge dam and other smaller reservoirs upriver are also having the same happen. It’s all about the electricity! The hottest city in the US, Phoenix, needs constant AC operating or everybody there dies. There is what, 4 million in that area now?

      So Hoover Dam is about to stop generating, you can see the foundations coming out of the water

      There’s a reason it’s called the DESERT Southwest. After all, take away the invisible line drawn on maps and what you have left is the Northern Sonora Desert of Mexico stretching up this way…

      It was 109’F/43C (or so) in Phoenix a couple days ago. It hasn’t even gotten hot yet…but the reservoirs are literally dropping daily from some of the youtube vid updates. They are about to become what is called a ‘Dead Pool.’

      When the power goes off…it won’t take long for heat stroke in the US southwest to be happening everywhere.

      My old friend Karin in Utah, lives in SLC (not mormon) has been talking about the toxic chemicals and radioactive fallout in the dust storms that have been blowing off the lake smothering the city this year. Read an article about it and saw a satellite picture yesterday. It is 1/3 the size of what I remember when I was at Utah State University in the late 80s… No wonder it’s blowing poison from the lake bed including fallout from the Nevada bomb tests of the 50s & 60s.

      A ‘glad I don’t live there’ moment except I know people who do…

      Today is 9July and the weather ‘storm chaser’ youtube channels are again going crazy in the Midwest and back East. The weather onslaught continues to spread an ever-larger area of this country.

      But the end of this vid is…extremely anthropocentric and I started snickering about, and I quote: “Human life will be the main value” with that close-up of the baby eyes starting at you on the screen. What an impressive piece of visual propaganda about getting together and building a ‘new world.’ Seems to me that this world has already achieved that quote don’t you think?

    “Five weeks. Five instances of 1,000-year rain events. If it seems like the weather across the Lower 48 as of late has been bonkers, you’re not imagining things. It’s been a maelstrom of weather extremes, a seesaw fluctuating wildly from significantly dry to record wet conditions.”



    • And that’s not counting the multiple 500 year rain events in different parts of this country. There were three of those that hit St. Louis in seven days I remember reading a couple weeks ago. And it just stayed hot and hot and hot here day after day for the last…oh hell I’ve lost track of the over 95’F days at this point. Probably crossed 50 days in a row I think. I just don’t do well in these temps…but for the most part the nighttime temperatures stayed in the upper 50sF to mid-60F range which at least allowed the house to cool down enough to sleep by 3am. There have been a few nights when it didn’t and was 79F at 3am which made for sleepless as the heat in the house just didn’t dissipate.

      Continuing craziness tonight 24Aug with a massive lightning show blowing through from the south. Came up from the south, straight up following the north to south line of the valley below with much more of it in the distance over the mountains on the other side. Literally hours of bolts hitting everywhere, ripping up above the clouds in miles-long fireworks like a never-ending artillery bombardment in a war. Deafening Craaak-SNAP with zero time between the flash & sound wave concussion to huge rumbling on and on from in the valley below up into the ridgelines of the Huckleberry Range to the west. Had a very large bolt hit on the ridge up above me, then another that was between me and the neighbors to the north both somewhere in the trees which means keep an eye out for wisps of smoke the next few days, but those were the only two that I saw on this side of the valley. How strange.

      Not a single drop of rain fell. You could smell the wetness but it never let loose. I unplugged everything as did my neighbors I was chatting with, then sat on the porch with a book light and read while the sky show raged. Dog slept through it all but the cat wasn’t happy. Finally went in and fell asleep in a reading chair up in the office (fans still going, windows open) as the flashes kept coming in the windows. Not having city lights sure does change the perspective on lightning shows! Slept until after 3am which is unusual for me so I’m now wide awake and watching the sliver of a crescent moon coming up behind the ridge out the east office window as I type this.
      Thought this was interesting. As if California isn’t getting blasting with enough radical weather:

      It’s almost 5am Thursday morning and 62F with 74% humidity (I just let the dog out and checked). Guess I get to see a sunrise today since I’m not sleepy at all.

      Back to the book I guess!

  16. But but this site says we should be a little worried about the coming Northern Hemisphere summer because, well, looks like El Nino will be back.

    Three years of La Nina but 2021 was pretty damned radical up here where I live. Don’t think I’ll survive Pakistan’s temps when they come. But then the Met Office isn’t saying that we’re over 2’C already. Wonder what year they start that, eh?

    2023 set to be tenth consecutive year at 1°C or above


    This summer isn’t going to be fun, but then (so far) this winter has absolutely sucked anyway. I’m still digging out and I just got brushed by that slab of Siberian Arctic air that fell off the top of the world by the Jet Stream…

  17. So the US gets temperature drops of 40’F in literally a couple hours with the ‘unprecedented’ frigid Arctic blast, and now Europe gets hit with an ‘
    ‘unprecedented’ heat dome:

    ‘Absolute Madness’: Record-Shattering Heat Dome Hits Europe

    It’s “the most extreme event ever seen in European climatology,” said one climatologist. “Nothing stands close to this.”


    With three feet of snow I’m already starting to really worry about the predicted El Nino that seems to be coming this year. It was 120’F in the 2nd yr of La Nina in 2021, last summer I saw 112’F, but with the Pacific about to heat off I guess I should be enjoying digging this much snow off of shit, eh?



  18. We have a Bomb Cyclone off the West Coast that is so similar to what hit Australia last summer it’s a bit freaky. Mixed with the Pineapple Express ‘atmospheric river,’ I’m getting reports from NorCal people (my younger brother is on the coast in Ft. Bragg) and from what I’m reading, this is all sounding very much like the photos and comments from my OB friend’s forwarded info from her granddaughter & g-grandkids who were in the Brisbane floods.

    I’m too far north, it’s not getting into my area yet but the cyclone off the coast is definitely moving north churning up the coast towards the Northwest. Rain predicted tomorrow here (IN JANUARY?) so I’d best go cut more firewood and get it into the house today. Never a dull moment in a destabilizing climate, eh?

    Lots of info etc online about what’s hitting the coast here so I’m not going to post any links. Besides, the weather ALWAYS changes so it isn’t a big deal, yes?

    It is barely below freezing at night here, barely above during the day, occasional snowflakes from the overcast but nothing that could be considered ‘snowing,’ and a very wet/icy snowpack to walk around on. Slick as frog snot! The dog is really missing chasing the ball she keeps bringing me because it’s too slippery for her to run on as I don’t want her breaking a leg…

    Nothing else from here for now…

    “Sea surface temperatures are a major influence on the world’s weather. Hotter oceans help supercharge extreme weather, leading to more intense hurricanes and typhoons and more moisture in the air, which brings more intense rains and flooding.”


  20. Holy fuck.

    NEGATIVE 108’F on Mt. Washington in New Hampshire. -108’F is…what in C?? I have no fucking clue but this is Antarctic weather on the US East Coast that has NEVER happened before.

    Here it is 34’F at 2am under a clear sky…should be 0’F at this time of year. Shit be REAAALLLLYYYY fucked up, Kev.

    • “And nothing changes.” at the end of paragraph 21. That pretty much concludes the argument for supporting the hopium of ‘adaptation’ that the New Zealand RWNJs are all about I would think.

      Kev, nobody will have the social resilience to handle what we face. The species is going to go insane with the fear when it finally breaks through the denial. And what does primate species do when they get scared badly enough? They get violent. Food runs out? They hunt one another. Back and back the written and unwritten history goes and at the end of each ‘major’ civilization what do the anthropologists find? Human bones cracked in fire-pits for the marrow.

      That George Carlin quote about the intelligence of the ‘average’ person and realizing that 50% of the population is stupider than that is…unnerving to think about in a situation we are talking about.

      And Big Bear in SoCal had 7 feet of snow in less than a wee that has buried them. Tornadoes are roaring through parts of the Deep South and Southeastern US destroying whatever is in the way…in January and February. Derechos dumping enormous amounts of water… TWO major cyclones hit Vanatua in the space of a couple of days, first a Category 3 then TWO major earthquakes hit. A 6.5 and a 5.4 before the next day’s Category 4 slammed in on them.

      This is nuts.

      But then there is this that published 4 days ago:


      The coming El Nino is really starting to…invade my dreams.

    “Recently, researchers calculated that the eruption of Hunga Tonga-Hunga Ha’apa spewed a staggering 50 million tons (45 million metric tons) of water vapor into Earth’s atmosphere, in addition to enormous quantities of ash and volcanic gases. This massive vapor injection increased the amount of moisture in the global stratosphere by about 5%, and could trigger a cycle of stratospheric cooling and surface heating — and these effects may persist for months to come, according to a new study.”
