An ignorant me growing in knowledge makes me happy. New knowledge that amazes me deserves to be captured.

  • Some parts of Africa ACTUALLY highly regard environmental protection. eg Rwanda's strict stance towards littering. Talk about stereotypes, most of us probably expect Africa to be a doggone Aids-infested place that the state of the environment wouldn't matter to them, right?
  • Water vapour is the most potent GHG. Just as I thought water vapour is all good cos I have only ever recognised it as something I learnt in p3 about the water cycle
  • Feedbacks in the environment are amazing. K though sometimes scary. It is amazing because it really shows how possible it is that one thing leads to another, the ones i know so far are more accurately about how one BAD thing eads to another - thus making it scary. Eg. What we know is CO2 emissions > Global Warming > Temperature rise > Polar ice caps melt > Sea Level Rise.

Yes? But there's many other aspects less mentioned yet also occuring. Higher temp > Ocean waters EXPAND > Sea level rise TOO Higher temp > More water vapour (which is a GHG) Higher temp > ice caps melt and methane within will escape, a more potent GHG than CO2 btw When ice caps (white) melt > Less albedo, just means temp will rise further eventually SCARY?

  • Volcanoes release sulfur particles into the air, which is a negative forcing. Years with certain such volcanic eruptions actually reduce heating effect cos they can reflect solar rays. YET sulfur particles in air could also cause acid rain..
  • A single substance of completely opposite implications at diffent levels of the atmosphere- ozone: bad near ground cos it's a pollutant, yet good as a layer in the stratosphere to protect us from UV. I have always heard about the ozone layer so I always thought ozone was just good and WANTED, but turns out it's undesirable when near us :/
