Solar radiation from the Sun reaches the Earth’s atmosphere The surface of the Earth absorbs most of the short-rayed insolation and later releases this heat in the form of infrared radiation into the atmosphere. Some of the heat is absorbed by particles known as “greenhouse gases.” The heat retained by the gases acts as a “heat blanket.”
Burning of fossil fuels
The burning of fossil fuels releases Carbon dioxide in the atmosphere. In
the past 150 years, burning fossil fuels has caused a 25 % increase in Carbon
dioxide emissions.

The Ties Between Sardines & Global Warming
The over-hunting of sardines has caused higher levels of phytoplankton in
the ocean.While living, phytoplankton release oxygen into the atmosphere and
use Carbon for photosynthesis
When they die, their decay releases large amounts of methane and the poisonous
gas, hydrogen sulfide. It also uses large amounts of oxygen.
Sardines & Global Warming
Methane is 21 times more effective than carbon dioxide in maintaining heat
in the atmosphere. This results in the deaths of numerous marine animals.
Effects of global warming
More carbon dioxide increase in plant growth. The increase in temperature rise in sea level from melting glaciers and polar ice caps (adds 0.2 mm annually)Rising temperatures will also cause drier conditions in many important agricultural regions.
GLOBAL WARMING: Sea Life
GLOBAL WARMING’S NEGATIVE IMPACT ON SEA LIFE
Change in temperature and elevated sea level cause loss of algae in the coral.
Coral appears white, or “bleached.” Result is mass death of sea
animals, which are dependent on the coral reef. The penguin population near
Antarctica has been declining as the distance between them and their food
has increased.
