Question 18Tips1 / 1 pts(Q021) This graph shows which of the following?Click to view larger image.  The global climate has warmed by about 1.2°C since 1950.  The global average temperature varies as much as 5°C from year to year.  The Earth's average temperature is currently 1.2°C.  All of the possible answers are correct.

In general, what does this chart show?Group of answer choicesa. Average ocean temperature has not changed since the start of the industrial revolution (mid 1800s).b. The oceans are becoming cooler.c. Ocean temperature is relatively stable.d. Ocean temperature is increasing in both the northern and southern hemispheres.

The mean global surface temperature has increased by about _____ over 1850-2020 values.(Fill in the Blanks with the correct answer)

Since 1975, Earth’s average temperature has risen nearly  . However, this warming has not occurred evenly across the globe. The map below shows how average temperatures have changed in different regions on Earth since the mid-20th century.A map of Earth is shown. A key shows the change in average temperature by color. Dark blue is more than negative 1.0°C, light blue is negative 1.0°C to negative 0.5°C, green is negative 0.5°C to negative 0.2°C, white is negative 0.2°C to positive 0.2°C, yellow is positive 0.2°C to positive 0.5°C, light orange is positive 0.5°C to positive 1.0°C, dark orange is positive 1.0°C to positive 2.0°C, light red is positive 2.0°C to positive 4.0°C, and dark red is more than positive 4.0°C. The continents are mostly dark orange with some areas of light orange. The ocean is mostly yellow and light orange with some areas of white. The high northern latitudes, including the Arctic, are mostly light red with some areas of dark red. The high southern latitudes, including Antarctica, are mostly light and dark orange with some areas of dark blue, light blue, green, and white.According to the map, where have the greatest temperature increases occurred?Choose 1 answer:Choose 1 answer:(Choice A, Checked)   at northern latitudes and over waterAat northern latitudes and over water(Choice B)   at northern latitudes and over landBat northern latitudes and over land(Choice C)   at southern latitudes and over waterCat southern latitudes and over water(Choice D)   at southern latitudes and over landDat southern latitudes and over land

Which of the following is not true of global warming? Global warming:Question 25Select one:a.refers to the recent and ongoing rise in global average temperature near Earth's surface.b.is caused mostly by increasing concentrations of greenhouse gases in the atmosphere.c.is any significant change in the measures of climate lasting for an extended period of time.d.is causing climate patterns to change.

Without the natural greenhouse effect, the average global temperature would be around ______.-18°C18°C-15°C15°C
