Global warming slowing down? 'Ironic' study finds more CO2 has slightly cooled the planet

GLOBAL WARMING has been "ironically" set back by more carbon dioxide (CO2) in the atmosphere, NASA scientists have astonishingly claimed.

metmike: Astonishing...............because it took them so long to re-discover the law of photosynthesis:

"Climate experts have found has been reduced by 0.2C to 0.25C degrees (0.36F to 0.45F) since the 1980s. The unexpected trend has been linked to carbon dioxide emissions feeding a surge in plant life growth."

The scientists have now established the planet is greener than it has been in the early 1980s. Forecast up until the year 2100 show the planet will likely become even greener.

"The process, known as evapotranspiration, occurs when plants consume the heat-trapping greenhouse gas and release water.

Much like humans sweating on a hot day, evapotranspiration can have a cooling effect on the air.

In other words, with more carbon dioxide feeding plant growth, the planet is slightly cooler than otherwise expected."

metmike: This is what I've been insisting...............using authentic data sources to prove the point.........for 2 decades.

Here's the actual study/paper: You won't find it on most MSM sources, because it doesn't fit the fake climate crisis narrative....... so read it here:

Characteristics, drivers and feedbacks of global greening

Key points

    Long-term satellite records reveal a significant global greening of vegetated areas since the 1980s, which recent data suggest has continued past 2010.                  
    Pronounced greening is observed in China and India due to afforestation and agricultural intensification.                  
    Global vegetation models suggest that CO2 fertilization is the main driver of global vegetation greening.                  
    Warming is the major cause of greening in boreal and Arctic biomes, but has negative effects on greening in the tropics.                  
    Greening was found to mitigate global warming through enhanced land carbon uptake and evaporative cooling, but might also lead to decreased albedo that could potentially cause local warming.                  
    Greening enhances transpiration, a process that reduces soil moisture and runoff locally, but can either amplify or reduce runoff and soil moisture regionally through altering the pattern of precipitation.                  

metmike: As they stated, global greening is likely to continue thru the year 2100(how would it not, based on the irrefutable law of photosynthesis?).

We are in the early stages of a climate Optimum for life on this planet!

Not to sound too sarcastic/cynical, but I'm surprised a paper that doesn't fit the narrative even got published in Nature.

This fact is one of the reasons why the Cornbelt is being protected from more major widespread droughts.

After averaging over 1/decade,  until 4 decades ago, we’ve only had 1 in over 30 can blame climate change.

Not just more rain but farmers are planting corn in tightly packed rows that are twice as dense as 4 decades ago.

This has created a micro climate during the growing season on the Midwest. 

The massive evapotranspiration increase has increased dew points by Over 5 deg. in many situations which provides additional moisture for weather systems to use......and return back as rain that goes back inTo the soils, pulled out by the plants.......evapotranspirates again and the positive moisture cycle/feedback repeats all Summer.

It’s not just corn in the Midwest but as this study showed.....plants around the globe are all flourishing And  this same effect.........also causes cooling.

Drought protection in many areas.

Also, CO2 makes plants more water efficient so droughts that always encompass something like 25% of the planet.......and are constantly moving around.......don’t damage plants/crops as much as they did 40 years ago with the exact same conditions.

This is not to ignore that we’ve had beneficial warming of 1 deg the past century and this increases evaporation that dries things out a bit faster in some places.

An increase in low level moisture at the same time decreases the evaporation rate.

The coldest places on the planet are warming the most during the coldest times of year where evaporation is not that significant to life.
