ANSWER: Climate Engineering
- Most climate engineering efforts can be divided into two categories - the management of carbon and the management of sunlight.
- For management of sunlight, the techniques being considered are marine cloud brightening, cirrus cloud manipulation and stratospheric aerosol injection (SAI).
- Low, warm clouds tend to be highly reflective to sunlight, especially when the cloud is bright due to the presence of smaller droplets (because of the Twomey effect). Therefore, modifying these clouds to make them more reflective cools the climate. This proposed technique is known as 'marine cloud brightening', 'marine sky brightening' or 'cloud whitening' of low cloud.
