Concept explainers
People tend to be much more attuned to what’s happening right now and less aware of long-term trends. Every time there’s a blast of cold weather in writer or hot weather in summer, opinion polls show lesser or greater concern about global warming. Climatologists, however, take a very long view and look for trends in climate data. Using a ruler, estimate trend lines for the data in Figures 29-14 and E29-2. What do the trend lines predict about the future of atmospheric CO2 concentrations, global temperatures, and Arctic sea ice? If these trends persist, will the Arctic become ice-free in late summer? If so, in what year? When will CO2 concentrations double from preindustrial levels and reach 560 parts per million? Is it reasonable to extrapolate straight (linear) trend lines into the future? Why or why not?

- The current and previous century's global warming trend is attributed to: A Increased volcanism and other natural process that release greenhouse gases B) None of the above. Increase greenhouse gases from fossil fuel consumption. The Earth's orbit becoming closer to the sun.arrow_forwardWhich of the following statements explains why temperature is considered a reliable metric to investigate climate change? Select all that apply: a. changes in other aspects of climate, such as precipitation or sea level, are a response to the temperature change b. there is a long-term global database for temperature c. temperature has been measured directly for millennia d. global temperature measurements include weather variabilityarrow_forwardIN MORE THAN 500 WORDS Aside from the rise in mean temperature and CO2 levels, what are some other pieces of evidence from global warming?

- Please exaplain The current trend in the warming of the planet, particularly since the year 1950, is primarily caused by 1. volcanic eruptions 2. the extent of cloud cover 3. changes in solar energy 4. changes in ocean circulation 5. the steady increase in the amount of greenhouse gases in the atmospherearrow_forwardThe graph shows that the atmosphere is currently warmer than it has been in Global Mean Temperature over Land & Ocean 0.6 0.4 0.2 0.0 -0.2 -0.4 -0.6 L 1 1940 1920 1960 anomaly ("C) relative to 1961-1990 1880 1900 O 100 years O 1,000 years O 120 years O 1,200 years year ↓ L 1980 2000arrow_forwardGlobal warming is dependent on the incoming rate of solar radiation as against the absorption of heat inside the earth. . true or falsearrow_forward
- Which of the following is NOT true about climate change? a. Today’s climatic warming particularly the warming since the mid-20th century is occurring much faster than ever before and cannot be explained by natural causes alone. b. Humans more specifically, the greenhouse gas (GHG) emissions we generate are the leading cause of the earth’s rapidly changing climate. c. The burning of fossil fuels like coal, oil, and gas for electricity, heat, and transportation is the primary source of natural cause of climate change. d. Activities like agriculture and road construction can change the reflectivity of the earth’s surface, leading to local warming or cooling, too.arrow_forwardThe warming trends discussed in the Case Study are most pronounced at the equator, where sunlight is most direct. What would you predict the effect of global warming to be nearer the poles, where temperatures are lower and there is less sunlight?arrow_forwardWhat pieces of evidence are presented that prove or reinforce the connection between climate change and the changing meteorological pattern?
