Agriculture and global warming Hello there! I am currently working on a debate on whether or not humans are causing global warming.

Now I need some help on finding how agriculture is not causing global warming. I know already how it is.

Also if you have time could you please tell me why the Earth%26#039;s cycle and Sun are not to blame...

But agriculture first please and thanks so much!

Earth is now at the peak of one of its passing warm spells. It started in the 17th century when there was no industrial influence on the climate to speak of and no such thing as the hothouse effect. The current warming is evidently a natural process and utterly independent of hothouse gases.

The real reasons for climate changes are uneven solar radiation, terrestrial precession (that is, axis gyration), instability of oceanic currents, regular salinity fluctuations of the Arctic Ocean surface waters, etc. There is another, principal reason—solar activity and luminosity. The greater they are the warmer is our climate.

Plant crops also absorb CO2 in order to grow, but I%26#039;m not sure how much is released at harvesting and it%26#039;s likely that in most conventional agriculture situations any benefit is mitigated by the fossil fuels used to produce the chemicals, ship and process the finished crop, etc. Likewise for organics, minus the chemicals.

Here%26#039;s info on why the sun and/or normal fluctuations in climate are NOT to blame for the current changes:

Well, the plants growing in the field do absorb Co2...not that its even been proven or able to be shown that co2 is a real culprit in the GW trend..but the academic dummies that refuse to even question that premis can at least academically agree with the idea that more plants is a good thing. However, as plants start to decay...they give off S2H4 which i%26#039;m not sure if anyone has actually tied to any specific action.
That%26#039;s one of the many factors people overlook or know nothing about. So, I too agree that for someone to step forward as Al Gore has and to arrogantly claim man is responsible for GW is nothing short (at best) a well meaning idiot. Problem is, History is full of well meaning idiots..and the end result of it has been more taxes, bad policies, screwy laws, Bigger Government, less freedom. When will humans learn this ?
As for not blaming the sun...wow.... I%26#039;ve looked at the models of the planetary system....Don%26#039;t know about you, but the sun is the only heating source i can find....to not blame it for heating trends is like testing out a home-made parachute and expecting gravity not to mess with you as you jump off the roof.
Can anyone predict that mass, energy and heat potential of the earth%26#039;s core ? Can anyone predict what would happen if the sun was simply removed and we had to rely on the planet%26#039;s core to keep things warm ?
These magnitudes of questions are largely unanswerable and haven%26#039;t been touched by mankind since they are nearly incalculable. Best we can attain is an %26#039;estimate%26#039; or a %26#039;guestimation%26#039;.
We can%26#039;t calculate ever effect that the sun%26#039;s magnetic flux interacting with the earths might cause. we can%26#039;t include every detail and factor that cause things to happen the way we do. We are making progress but seems the big GW craze is largely fueled by ignorance of the masses and bad science whom were too presumptive to think the planet is equivalent to thier petri dish. 0% 0 Votes
