Chapter 47, Problem 4DAA
Sea Temperature To predict the effect of El Niño or La Niña events in the future, the National Oceanographic and Atmospheric Administration collects information about sea surface temperature (SST) and atmospheric conditions. They compare monthly temperature averages in the eastern equatorial Pacific Ocean to historical data and calculate the difference (the degree of anomaly) to determine if El Niño conditions, La Niña conditions, or neutral conditions are developing. El Niño is a rise in the average SST above 0.5°C. A decline of the same amount is La Niña. FIGURE 47.8 shows data for 42 years.
FIGURE 47.8 Sea surface temperature anomalies (difference from the historical mean) in the eastern equatorial Pacific Ocean. A rise above the dashed red line is an El Niño event, a decline below the blue line is La Niña

Climatologists look for climate change in many components of the climate system. Which of the following statements has the least direct evidence?
A. Global mean surface temperature has increased since 1850.
B. Arctic sea ice, glaciers, and ice sheets have decreased in size over the past 50 years.
C. The length of the growing season in the US has decreased since the 1890s.
D. Global mean sea level has risen significantly since 1880.
Here is some data about sea level rise in the Chesapeake Bay. The data shows the change in sea level over time. Notice that there are four sea level measurements per year because they are done during each season (fall, winter, summer, and spring).

- Climate is the result of a variety of global processes. What of the following is a climatological driver? rotation of Earth hydrosphere properties oceanic currents concertation of sun irradiances all of the abovearrow_forwardPredictions of hydroclimatic change with global warming suggest that precipitation events are becoming/will become more extreme. In other words, heavy/flooding precipitation events will occur with greater frequency. Explain how the capacity of Earth’s atmosphere to hold water vapor changes as the atmosphere warms, such that heavier precipitation events could be triggered.arrow_forwardWhich of the following statements about atmospheric carbon dioxide levels is correct? For about 800,000 years prior to human influence it varied between 180 and 300 ppm and is now above 410 ppm. For about 800,000 years prior to human influence it never exceeded 200 ppm. Its rate of increase in the past century is greater than any seen in the ice core record. Both 1 & 3arrow_forward

- Select the correct terms: (Climate / Weather) is the short-term atmospheric conditions in an area, while (climate / weather) is the average atmospheric conditions in a given area over a long period of time. (Climate change / Global warming) consists of the long-term and largescale changes in atmospheric conditions, which have been brought about by (climate change / global warming), an increase in the average global temperature.arrow_forwardHuman lifestyle choices currently release greenhouse gases into the atmosphere at higher rates than what occurs naturally. When greenhouse gases like carbon dioxide, methane, and nitrous oxide accumulate they trap heat. As a result of this trapped heat, temperatures on Earth's surface are changing Figure 1 - Greenhouse Gas Emissions by Humans Choice and the Greenhouse Gases Emitted as a Result Which of these ideas would be the best course of action for decreasing land temperatures? 1. Phase-out agricultural production, since that sector, produces the largest amounts of methane and nitrous oxide. 2. Decrease land use and biomass burning, because this sector produces all three major greenhouse gases. 3. increase the number of waste disposal and treatment plants because they do not release carbon dioxide 4. Develop alternative energy sources to decrease the amount of carbon dioxide released as a result of power stationsarrow_forwardThe warming trends discussed in the Case Study are most pronounced at the equator, where sunlight is most direct.
