  • Sunshade(BBC link) most expensive way to save eath from global warming. Main idea is reflex sunlight out of world (Dr. Roger Angel(University of arizona) says that 2% reflexion is enough). To do this idea we must create 1.6 trillion sunshades to reflex sunlight(1 million miles from earth). All of sunshades after send to space is wide 100,000 miles in L1 zone(L1 in wiki). Dr Angel estimate sunshades may have 20 million tons(one spaceship may contain 23 tons/trip and $450 million/trip).Total cost to send sunshades to space is about $392,000,000,000,000 (392 trillion us dollars)!!!!!
  • Cloud making(BBC link) use cloud to reflex sunlight. Prof. John Latham and Prof. Stephen Salter think we can use cloud (Marin stratocumilus?) to reflex sunlight by using boat to spin sea water to feed cloud. problem is how can we feed cloud and don’t let cloud to be rain. Boat can send sea water to the air and salt cystal that cannot be evaporate is a glue to hold water molecule together and more reflex power
  • Sulphur screen(BBC link) idea from volcano explosion and it release sulphur dioxide in the air (The Toba volcano explosion 71,000 year ago make 6 years winter and Ice-age 1000 years). Sulphur dioxide cloud can absorb and reflex sunlight. To do that we must send Sulphur dioxide (sulphur dioxide in layer below stratosphere is danger) about 25 million tons to stratosphere. This idea is more dangerous because it may destroy ozone of make a acid rain.
  • Phytoplankton(BBC link) is small plant that can absorb carbondioxide and release oxygen. when phytoplankton die they’ll sink and keep carbon in their cell. Prof. Ian Jones think we can feed phytoplankton by urea. Disadvantage of this idea is more phytoplankton may kill fish.
  • Artificial Trees(BBC link) it may be best alternative to save the world. Key is collect carbondioxide and keep it in underground by build a carbondioxide extractor called Artificial Trees. Artificial Trees collect carbondioxide by soduim hydrocide and extract carbondioxide out later. problem is where we can keep carbon?. Answer is keep it in stone layer under ocean.
