My Investigation on climate change
ACIDIFICATION
DEFINITION:But overfishing and global warming threaten to leave oceans barren. The ocean is a continuous body of salt water that covers more than 70 percent of the Earth's surface.
What is happening to the oceans?
Carbon dioxide (CO2 ) is produced every day and absorbed by the oceans. As CO2 reacts with seawater, it lowers pH and reduces the concentration of carbonate ions. Motor vehicles and other transportation-related sources produce CO2.The ocean contains about 97% of all the water on Earth. The ocean plays a starring role in whatever happens with the environment. One big part of its role is to soak up energy (heat) and distribute it more evenly around the Earth.
What does this do to shellfish Higher temperatures and lower salinity will result in a habitat favored by microscopic bacteria in the oceans. More bacteria will impact marine species higher up the food chain. ... These can accumulate in shellfish such as mussels and oysters, putting the humans who eat them at risk.
Definition Ocean acidification refers to decreasing levels of pH in the ocean, which makes the sea more acidic. It is the long-term change in seawater chemistry due to the absorption of carbon dioxide from the atmosphere. Roughly 30 percent of human-made CO2 is absorbed by the oceans.

DEFINITION:Trees and forests provide a habitat for many species of animals and plants. Tropical rainforests are among the most biodiverse habitats in the world. Trees provide shade and shelter, timber for construction, fuel for cooking and heating, and fruit for food as well as having many other uses.
What are trees used for? oxygen
HOW DOES DEFORESTATION AFFECT THE CLIMATE?Trees provide them shelter from the weather and from enemies. Trees provide food in the form of fruits, nuts, leaves, bark, and roots. Even dead trees provide shelter and food for many insects.

ICE CAP MELT
DEFINITION:If all the ice melted what would happen?If all the ice covering Antarctica , Greenland, and in mountain glaciers around the world were to melt, sea level would rise about 70 meters (230 feet). The ocean would cover all the coastal cities. And land area would shrink significantly. ... That's because the ice doesn't just melt.
HOW DOES ICE CAP MELT AFFECT CLIMATE CHANGE?The primary cause of this phenomenon is ice-albedo feedback, whereby melting ice uncovers darker land or ocean beneath, which then absorbs more sunlight, causing more heating.

WATER VAPOUR
DEFINITION:Increased water vapor content in the atmosphere is referred to as a feedback process. Warmer air is able to hold more moisture. As the climate warms, air temperatures rise, more evaporation from water sources and land occurs, thus increasing the atmospheric moisture content.Apr 27, 2016
HOW DOES WATER VAPOUR AND EVAPORATION CONTRIBUTE TO CLIMATE CHANGE?
It is known that climate affects the ocean and the ocean affects the climate. Due to climate change, as the ocean gets warmer this too has an effect on the seafloor. Because of greenhouse gases such as carbon dioxide, this warming will have an effect on the bicarbonate buffer of the ocean.
