Blue Planet: Designer Planet Questions and Answers 100% Correct

Blue Planet: Designer Planet Questions and Answers 100% Correct Based on the information in the images to the right, which of the following areas will be impacted if we reach 2 degrees Celsius of warming? Select all that apply ALL Which of the temperatures below do you think is a good target for maximum warming in the next 100 years? For reference, we were at about +0.6oC from the average in 2014. Next, you'll test scenarios to reach the target you choose. You'll be scored for completing this screen, not any particular response. +2 degrees Celsius What is the level of warming by 2150 8 ^ repeat 8 Let's see just how good we are as a society - if we put in maximum effort on every single possible technology as soon as possible, where would our temperature rise be by 2150? 2 Is your initial target possible with the technologies you tested? Yes What are some of the environmental impacts of your targeted warming level? Use the data at right for reference Increased damage from floods and storms, increased coral bleaching and increased species ranges shifts and wildfire risk What do you think some of the economic impacts of your targeted warming level will be? These could be related to the costs of getting to your target with current technology, or costs from the environmental impacts you identify Complex, localized negative impacts on small holders, subsistence farmers and fishers as well as the increasing burden from malnutrition, diarrhea, cardio-respiratory, and infectious diseases Think back to what you've done so far - what are the factors that affect the temperature of the Earth? Albedo Solar Luminosity Distance from the Sun Atmosphere Which of these factors do you think are areas that could be changed deliberately by human endeavor in the near future? ALL (except distance from the sun) In 1991 an event occurred which changed the Earth's albedo temporarily - what was that event? a massive volcanic eruption If human-made aerosols were introduced into the atmosphere, how could they help reach your warming target? Aerosols reduce the amount of solar energy reaching Earth, reducing its temperature Take a moment to think about the possibility of adding aerosols to Earth's atmosphere deliberately. I think this could be hit or miss. There are risks involved in doing so and in not. The risk of unchecked climate change compared to risks of doing geo-engineering. What would be the impact on Earth's climate of reducing the brightness of the Sun? Less energy would arrive at Earth, and the overall temperature would drop Take a moment to think about the possibility of reducing the brightness of the Sun deliberately. I hate the idea of this, it seems like a cop out instead of fundamentally addressing why humans have made the problems of global warming worse to begin with. If carbon dioxide is behind the warming trend, why not just remove carbon dioxide from the atmosphere? What effect might this idea have on Earth's climate? Carbon dioxide concentrations and temperatures would drop slowly Take a moment to think about the concept of storing carbon dioxide within deep geologic formations. I believe a more productive approach would be addressing human impact and educating people on sustainability and the effects of not caring more Think back to your experiences with photosynthesis - what is a benefit to humans that might come from biomass absorption of carbon dioxide that wouldn't come from factories liquifying and storing it? Select all that apply. More oxygen will be present in the atmosphere Some of the biomass might be able to be eaten or turned into fuel dum I think implementing many sustainable practices at once may cause confusion for humans but I also think it will be worth it in the long run, to keep the earth in livable conditions. While the cost of technologies required may be high, it is worth investing in as no other purchases will matter if humans do not have a planet to exist on.
