Greenhouse effect
Explanation of greenhouse effect and enhanced greenhouse effect.

The enhanced greenhouse effect (Global warming)
The enhanced greenhouse effect, sometimes referred to as climate change or global warming...
Climate change the enhanced greenhouse effect
Climate change on Earth is not a new phenomenon; there have been many ice ages and warm periods.
Climate change: science and impacts factsheet
Climate change is altering temperature, precipitation, and sea levels, and will adversely impact humans and natural systems, including water resources, human health, human settlements, ecosystems, and biodiversity.

What is coral bleaching?
Warmer water temperatures can result in coral bleaching.
Coral bleaching
The article explains coral bleaching, its causes, effects on the Great Barrier Reef.
Climate change and coral bleaching
Coral bleaching occurs when the zooxanthellae leave the corals—without the nutrients provided by the zooxanthellae, the corals eventually die of starvation and disease.

How are sea levels changing?
The estimated contributions from ocean thermal expansion and a then smaller Greenland Ice Sheet imply a contribution also from Antarctica to this higher sea level.
Sea level rise
...over the past century, the average height of the sea has risen more consistently—less than a centimetre every year, but those small additions add up.
Climate Change: Global Sea Level
Global mean sea level has risen about 8–9 inches (21–24 centimetres) since 1880, with about a third of that coming in just the last two and a half decades.

Currents
Winds drive ocean currents in the upper 100 meters of the ocean’s surface. However, ocean currents also flow thousands of meters below the surface.
Ocean on the Move: Thermohaline Circulation
The currents flowing through the ocean, a process called thermohaline circulation, can have an impact on climate.
The Thermohaline Circulation - The Great Ocean Conveyor Belt
The oceans are mostly composed of warm salty water near the surface over cold, less salty water in the ocean depths.
