Grassroots lobbying From Wikipedia, the free encyclopedia. Grassroots lobbying (also indirect lobbying) is a form of lobbying that focuses on raising awareness of a particular cause at the local level, with the intention of reaching thelegislature and making a difference in the decision-making process.
A heatwave is caused by a system of higher atmospheric pressure. In a high pressure system, air from upper levels of the atmosphere descends and rotates outward. As it comes down, it becomes compressed, which increases its temperature and dries it out.
Global Warming Causes Less Hurricanes. It is not just warm water which causes hurricanes. It is the temperature difference between the ocean surface and the upper atmosphere. The higher that temperature difference, the more hurricanes will form, and the stronger they will be. Global warming models all agree that the temperatures will rise more in the upper atmosphere than at the surface.
