Chapter 47, Problem 3DAA
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
During a La Niña event, less rain than normal falls in the American West and Southwest. In the time interval shown, what was the longest interval without a La Niña event?

Ocean acidity has been steadily decreasing from 20 million years ago to the present time.arrow_forwardThe Earth's climate has changed throughout history. Just in the last 650,000 years there have been seven cycles of glacial advance ar etreat, with the abrupt end of the last ice age about 7,000 years ago marking the beginning of the modern climate era and of human Civilization. Most of these climate changes are attributed to very small variations in Earth's orbit that change the amount of solar ene our planet receives. The current warming trend is of particular significance because most of it is very likely human-induced and proceeding at a very rapid rate not seen in the past 1,300 years. Earth-orbiting satellites and other technological advances have enabl- scientists to see the big picture, collecting many different types of information about our planet and its climate on a global scale. www.om Warming oceans Carbon dioxide levels continue to rise.
