Forest
A forest is a large area dominated by trees. Hundreds of more precise definitions of forest are used throughout the world, incorporating factors such as tree density, tree height, land use, legal standing and ecological function. According to the widely used Food and Agriculture Organization definition, forests covered 4 billion hectares (9.9×109 acres) (15 million square miles) or approximately 30 percent of the world's land area in 2006.
The brightness of the Sun varies on all time scales and wavelengths. An EU-funded initiative is gathering scattered observations from over 25 instruments to accurately represent how solar irradiance variability influences Earth's climate.
