Called World3, this computer model was cutting edge. Colorado being at the geographical nexus of much of the extremely risky testing that is conducted in this regard has received the brunt of the boomerang effect.
It reads something like this: A pessimistic scenario considers qualitatively the possible consequences of climatic changes and ground-level ultraviolet radiation increase that could depress crop yields, coupled with the high UN population growth projection, leading to nearly 13 billion people in We do not consider here the considerable challenge that this provides When drought and wildfires alternate with deluges and floodsit means that the weather patterns have been profoundly disrupted.

Green House Effect: This is a phenomenon characterized by warming of. Global Climate Change does not accurately describe the planetary predicament; an ongoing worldwide atmospheric apocalypse does.
This global phenomenon is manifesting as localized weather cataclysms, which are directly caused by a radical trend toward global warming, NOT global cooling. In fact. Exposing the climate geoengineering cover-up. Though the official ozone layer “recovery” lie is still being propagated, some sources are acknowledging reality as the truth becomes ever more difficult to hide.
Much more geoengineering / ozone destruction supporting data is listed below. Read National Geographic's latest stories about the environment. Ozone Layer Depletion and Global Warming Essay OZONE LAYER DEPLETION AND GLOBAL WARMING OZONE LAYER DEPLETION AND GLOBAL WARMING.
The ozone layer acts as a giant sunshade, protecting plants and animals from much of the sun’s harmful ultraviolet radiations. The impact of ozone depletion.
