Evapotranspiration is cooling. It is well understood too much CO2 will warm the planet, but an overlooked phenomena known as "evapotranspiration" is cooling.


Professor Wilhelm Ripl of the Technical University of Berlin,
"What is overlooked is the fact that intact vegetation 'actively' helps manage the small water cycle, and keep the earth cool by converting sensible heat to the latent heat of evaporation".


Amazon "raining upwards".

I like to think of evapotranspiration as raining upwards, in the Amazon rain forest, a single large tree can transpire up to 1,180 liters of water per day, which adds up to trillions raining upwards every day. Evapotranspiration is occuring all the time in varying degrees across the planet, it's the amazing water cycle and it's cooling... when there's water to evaporate.

We understand that greenhouse gases warm the planet,
but do we know what cools the planet.


The Thermoregulator of heat is water - water is cooling - "lack of water" is warming.

Land stores both water (aquifers) and heat (mass). When aquifers are low the land warms. Warmth stored in land mass accumulates, and unless water is present to evaporate and dissipate the heat - the heat increases the ambient temperature of the air - increasing air movement fuelling winds that dry the land - further drying and warming. GET IT!

This pattern continues until water returns - whether by nature or by man.

Knowledge about what cools the planet is vital
if we are to manage warming.

Both the carbon and water cycles are inexplicably linked - from a holistic view it is all interconnected - water, heat, soil, CO2, sun, land, sea, wind - everything is interconnected - holistic.

Suffice to say, the magnitude and the dimension of heat generated by desertification could be sufficient enough driver of warming that may be included in a climate change world.


Why is there so much talk about warming and climate change and nothing about HEAT ACCUMULATION. So why is there Heat Accumulation? In a word, "ploughing".

After Mother Earth has given life to some dust, sown her little seeds, delicately nurtured her microbes and meticulously woven her web of life, WE PLOUGH IT!

Ploughing cuts the soil, destroys the network of roots and the microbes and insects and all life is disrupted, sounds like war, divide and conquer. Ploughing turns the soil exposing it's nutrients to the sun, draining nutrients rapidly instead of progressively. The soil loses its' life force in a few seasons, after which we have to expensively prop up with artificial fertilisers.

Think about it. How thick is your skin? Not very, but it affords absolute protection. It's the same for land and soil.

The precious top inches of soil is known as the topsoil. Lose your top soil (your skin) and you will only last hours. We turn over the layers of soil, somewhat reversing millennia of Nature's weaving. In our ignorance WE PLOUGH IT without recognising that it was teaming with life, and a working system.


Do we?

Now that we have ploughed and ploughed,
taken the bumps, made flat the land,
sown mono-culture, added artificial fertilisers,
the soil will eventually warm.

We have as much water today as we have ever had. No more no less. More people will mean we will need to conserve water better... not flush it into the sea. Who's idea was it to direct good rain water into the sea anyway? Well, it was okay at the time, but things change and we must adapt.


In point form:

  1. Ploughing the soil destroys the infrastructure of soil - and tractors and fuel are expensive.
  2. Everyone leaves (life forms, water and CO2) - planting mono-culture further depletes nutrients - soil then requires artificial help which is expensive.
  3. Water and CO2 can't settle in the soil anymore - so CO2 hangs around the atmosphere which adds to climate change and water rolls off (flooding) instead of being absorbed into water sinks to refill aquifers.
  4. The less water the more heat - the more heat the less water.
  5. No water means no trees - so there are no roots to hold the land together.
  6. Keep this up and eventually it blows away (desertification) becoming a desert.
  7. We must change how we do things.
  8. First stop ploughing.

What has so much ecology got to do with technology?

  • The lessons learned from natures' methodology can be applied to technology. It's not an autonomous engine - but an engine within an eco system - that's what sustainability is - technology must fit within the structure of Earth. Biomimicry is such a technology.
