For Gardening on a slope sure is difficult, but its definitely not impossible. conditions. Regions with a higher fuel moisture or sparse fuel coverage may present a barrier to fire spread. Since there are 4 degrees of latitude difference between southern and northern Wisconsin, events can be expected to occur about 6 days later up north. How do slope reversals affect fire spread and firefighting operations? As evidence mounts for sustained global warming during the last half of the 20th century and the start of the 21st century, there is increased awareness of the relative importance of methane (CH 4) to greenhouse warming.In the most recent assessment of the Intergovernmental Panel on Climate Change [Intergovernmental Panel on Climate Change (IPCC), 2013], methane (CH 4) was . spread, though spotting associated with high winds can produce spot fires potentially miles away.
