Scientists cannot predict what human related emissions will be like in the future. Will they continue to grow or finally be scaled back? Scientists cannot predict any nuclear war that could affect the climate

There exist many positive feedback loops, so increases in temperature will lead to further increases such as the snow-albedo effect. Since human consumption and emission rates are rising and the population is also growing, this magnifies emissions

a) Clean energy sources are often renewable energy sources that do not create any wastes or pollutants

b) Ontario uses solar panels and wind turbines to harvest the sun’s energy as well as that from the wind

a) Clean energy sources are often renewable energy sources that do not create any wastes or pollutants

Three separate models may be created for dealing with human uncertainty where one assumes current trends of increased emission to hold, one assumes the trends to decrease, and one assumes that current rates stay exactly the same.

a) hydroelectric dams may harm fish that swim through the turbines.

b) Nuclear power stations can be very dangerous if not managed properly and release radioactive waste.

c) if corn-based biofuels became the norm, some regions would be unable to grow properly due to climate, putting them at a severe trade disadvantage

a) hydroelectric dams may harm fish that swim through the turbines.

Installing solar panels on the roof for electricity, start collecting our own water using rain-barrel gutter systems, and potentially building a windmill in the backyard in rural locations
