Climate change is already underway and is predicted to worsen. Human industrial activities, most notably those that involve the use of fossil fuels, are partly responsible for the accumulation of excess greenhouse gases in Earth’s atmosphere. The resultant increased rate of warming promotes droughts, wildfires, sea level rise, and other hazardous outcomes for people, crops, wildlife, and infrastructure.
The impacts of climate change could cost $1.9 trillion per year (in today’s dollars) by 2100 according to Frank Ackerman and Elizabeth A. Stanton of the Global Development and Environment Institute and Stockholm Environment Institute-US Center. Their analysis is based on just four symptoms of global warming: hurricane damages, real estate losses, energy costs, and water costs. They go on to state that immediate greenhouse emissions reductions are necessary to prevent most of global warming’s damages.
Other problems associated with climate change like declining biodiversity and decreased agriculture production will likely lower economic output in countries that rely on agriculture for total productivity. Jobs in agriculture, fishing, logging, and aquaculture require specific climate conditions and predictable weather patterns so that food, medicine, and material demands for human populations can be met.
