Question

Which of these is an unlikely consequence of a warming climate?

A. Reproductive events will occur earlier in the spring for some organisms
B. Some species will shift their geographic ranges toward the equator
C. Some populations will decrease in size as mortality increases
D. Some fishes will be move to deeper water

Answer 1

B) option is correct

Step-by-step explanation:

• The gradual heating of Earth's surface, oceans and atmosphere, is caused by human activity, primarily the burning of fossil fuels that pump carbon dioxide, methane and other greenhouse gases into the atmosphere
• One of the most immediate and obvious effects of global warming is the increase in temperatures around the world
• The average global temperature has increased by about 1.4 degrees Fahrenheit (0.8 degrees Celsius) over the past 100 years, according to the National Oceanic and Atmospheric Administration (NOAA)
• Changes in climate can cause the polar jet stream — the boundary between the cold North Pole air and the warm equatorial air — to migrate south, bringing with it cold, Arctic air
• Global warming may also lead to extreme weather other than cold or heat extremes
• One of the most dramatic effects of global warming is the reduction in Arctic sea ice
• The melt means there is less thick sea ice that persists for multiple years which means less heat is reflected back into the atmosphere by the shiny surface of the ice and more is absorbed by the comparatively darker ocean, creating a feedback loop that causes even more melt
