CLIMATE CHANGE The effects on Plant Species

WHAT IS CLIMATE CHANGE?

As Earth warms, particularly by the expansion of the burning of fossil fuels, causing an increase of the amount of carbon released in the atmosphere, this is something called

CLIMATE CHANGE

EFFECTED PLANT SPECIES
Coral reefs, eel grass, and algae.
WHY IS THIS SO IMPORTANT TO LEARN ABOUT? WHY IS IT SUCH A BIG PROBLEM?

Food Chain Disruption

The impact of climate change on one plant can affect a whole range of other plants and animals. For instance, if coral reefs start to become extinct, the many sea creatures that use coral reefs as their habitats, will start to become extinct, causing the predators of fish to also die out because of the lack of food. This chain will keep on going, and eventually reach to us -- humans.

Range Shifts

As the temperature increases, those (as in plants and animals) that can only live in certain colder climate starts to move north and to higher elevations. While this means a range expansion for some species, for others it means movement into less hospitable habitat, or a decrease in range with some species having nowhere to go because they are already at the top of a mountain or at the northern limit for their suitable lives.

Change in Timing of Seasonal Life Cycle Events

For many species, the key events to life is, such as migration, blooming and reproduction. As winter shortens, the timing of these events in different countries has changed. For example, "In a California study, 16 out of 23 butterfly species shifted their migration timing and arrived earlier." When these migrants arrive, either they are too early or too late for present food sources.

Extinction Risks

Study estimates that 20-30% of the plant and animal species evaluated so far in climate change studies are at a risk of extinction if temperatures continue to rise by the end of this century.

WHAT DO SCIENTIST KNOW/DON't KNOW?

Know

Scientists have strong evidence for, it is that greenhouse gases, including carbon dioxide, warm the planet. The atmospheric CO2 is increasing, which is caused by human activity. The temperature of the oceans are rising as well as the humidity, sea level -- and melting ice.

Don't Know

On the other hand, scientists are still discussing over, what will our future emissions be like? How much temperature will rise from the given emission pathway? And what are the effects of temperature rising?

SOLUTIONS

To give coral reefs a better chance of surviving climate changes, swimmers and divers should treat the ecosystem with care.
