Scientists believe we are experiencing a dramatic change in the overall climate system, verified by the 10;15 cm rise in sea levels over the last 100 years and the increases in severe weather conditions. Although climate change occurs naturally, scientists believe human activities have led to increased carbon dioxide, methane and nitrous oxide concentrations, leading to climate changes and, in turn, observed increases in sea levels, atmospheric temperatures, and erratic weather systems. This means that todays climate shift differs dramatically from previous shifts in climates in both magnitude and rate. Scientific research suggests that advancing sea levels, rising temperatures and severe weather conditions caused by climate change will result in a host of negative consequences such as a threat to international trade patterns, an increase in themovement of tropical disease, and an increased risk of forest fires and landslides.
