MIT modeling study finds 52% of projected global population in 2050 will live in water-stressed areas

Green Car Congress

A modeling study by researchers at MIT projects that 5 billion (52%) of the world’s projected 9.7 billion people in 2050 will live in water-stressed areas. The researchers also expect about 1 billion more people to be living in areas where water demand exceeds surface-water supply. billion living in developing countries.

A New Energy-Efficient Hydrogel Pulls Water From Air

Cars That Think

Using a new kind of hydrogel material, researchers at the University of Texas at Austin have pulled water out of thin air at temperatures low enough to be achieved with sunlight. Atmospheric water harvesting draws water from humidity in the air. The material is a hydrogel, a polymer network that naturally retains a lot of water.

MIT and Caltech Study Finds Climate Change Will Result In More Extreme Rainfall

Green Car Congress

A new MIT and Caltech study on the impact that global climate change will have on precipitation patterns concludes that extreme rainfall will increase in the future. The basic underlying reason for the projected increase in precipitation is that warmer air can hold more water vapor.
