The lake of Zurich as the human, no-infrared eye cannot see

Slightly more than half of the energy from the Sun arrives on Earth in the form of infrared radiation. Water absorbs the infra-red radiation, that explains the black lake and forests under the clouds.
The different pigments in plants reflect, transmit, and absorb different portions of the near-infrared radiation that we cannot see. Some plants can reflect more than others.
The clouds absorb visible and invisible radiation from the sun and re-emit much of the energy as infrared back to the atmosphere. Enjoy the reflecting trees and clouds: can you find the snow reflecting infra-red in the background?
