The problem is that they are destroying the forests to make homes. That's a big reason why it is getting so hot. In the 1970s, the highest daytime temperature in SG was 27 deg. Not only Tengah look at the flats along Bt Batok Rd, which used to be a vegetated area. You even feel cooler in the mornings. Why are we building so many buildings when the birth rate is declining?
Air conditioning is human created positive feedback. Vegetation actually has a higher albedo than some concrete because vegetation can absorb more solar radiation than buildings. The primary reason why temperature don't rise much in vegetation is because of evapotranspiration. Water can trap a lot of heat. 1kg of water requires 2260kJ/kg to turn into water vapour but requires only 4.2kJ per kilogram per degree celcius. Evaporation will increase humidity, so wind is important to prevent excessive build up of humidity.
"sustainability shouldn't be a question of why, but how." Are there still people who ask why??? My philosophy is "don't complain that weather so hot when you're still asking for plastic bags" (just an example k I know there's a debate about plastic bags but sustainability in general)
At the end of the day i believe that mankinds destiny is to soar beyond the stars. We will need to find a new home or form colonies as part of a chain of inter galatic species
Make Singapore Cool Again
Well tell that to the superpowers which want business and want money

Tengah: now, we are COOL!
He is there to promote centralised cooling system ie district cooling plants. Which will reduce energy consumption and heat in to the environment.

No leh, now singapore super cool, it's like 25-26 every night
Have you taught about the distribution of the airborne risks? This is the same as if everyone uses the same straw for their tea-milk.
Cool video talking about how to create a cooler environment and all, but the video barely talked about the actual place like the title suggests?

Meaning old estates will go bye bye
I was thinking the coolest place in Singapore was ISD... Guess I was wrong

So make Tesla cheaper ah sia
Everything comes with a cost
The initial cost. In the long run, it not only helps the environment, it's also more cost effective in comparison.
@@andichua9007 yeah maybe just put plants on top of buildings i guess
But no one wants to go to tengah :(
Well tell that to usa and australia the place to get the best for your future😎
