The trees are often scorched and burnt up, as with the most excessive heat, in consequence of the separation of water from the air, which is therefore very drying. In the great frost in 1683, the trunks of oak, ash, walnut, and other trees, were miserably split and cleft, so that they might be seen through, and the cracks often attended with ...

Plants cool when they transpire. Evaporating water and transmitting it through leaf stomata requires a lot of energy. Fred Pearce states that “a single tree transpiring a hundred litres of water a day has a cooling power equivalent to two household air-conditioning units” [7] (p. 29). An individual tree can transpire hundreds of litres of ...
These movements worked to avoid photo-inhibition and keep leaf temperature lower than the air temperature. [12] In sunflowers, we find a different relation involving floral warming. The floral heads of these plants follow the sun from east to west causing increased solar irradiation heating the plant. This resulted in more pollinators being ...
