We'll look at ocean warming.

Excess carbon dioxide is not only driving global warming, it's also changing ocean chemistry, making the sea more acidic.

Beyond warming, we have the problem of the oceans getting more acidified and already measurably so, and already affecting animals.

As the surface of the ocean gets warmer, the water is lighter when it's warmer, it becomes harder and harder to turn the ocean over.

In late September, the Intergovernmental Panel on Climate Change reported that the oceans are warming, seawater is acidifying, and oxygen concentrations are dropping. Last week, another initiative, the International Program on the State of the Ocean, outlined the toll that these and other factors, such as destructive fishing and pollution, are having on marine life.

As a result of global warming, a number of island states in the Pacific Ocean have seen their land and water resources that residents depend on for survival engulfed by rising sea levels.

Even a small warming of the Southern Ocean seems likely to initiate major changes in species survival.

Now, in this slide the white is chalk, and this chalk was deposited in a warm ocean.

As global warming increases, sea levels get higher and higher.

The total amount of heat contained in oceans responds to changes in emissions, and is therefore a better metric for measuring such responses. Indeed, it has continued to warm as expected, even as the surface temperature has stopped rising.

And now I mainly write books about how the ocean is changing, and the ocean is certainly changing very rapidly.

Sea levels are rising, and Kiribati, along with 42 other nations in the world, will be under water within 50 to 100 years due to climate change and the associated sea level rise from thermal expansion and the melting of freshwater into the ocean.

So, global warming, sea level rise, it's a real serious issue.

But the reason it has occurred is not that our greenhouse gas emissions are no longer changing the earth s climate it is that surface temperature is a poor metric for human induced warming. Indeed, what scientists have figured out is that, instead of warming the surface, the excess heat that is being generated has gone to the deeper oceans.

But there goes salmon sharks with this meter level resolution on an ocean of temperature warm colors are warmer.

(b) The emerging issues examined in the Global Environment Outlook Yearbook 2006, which are the environmental effects of the practice of farming of marine species and the overall impacts of global warming on food production.

Expressing its concern over the projected adverse effects of anthropogenic and natural climate change and ocean acidification on the marine environment and marine biodiversity,

Given the oceans massive heat storage capacity, determining how much of the warming remains at the surface over the course of decades is a very difficult task. Though the challenge is beginning to be appreciated, current projections of the dreaded two degree warming have yet to take into account variable ocean cycles.

So anything that influences how ocean surface waters mix with the deep water changes the ocean of the planet.

The rising concentration of carbon dioxide and other greenhouse gases is leading to more extreme storms, higher intensity hurricanes, rising ocean levels, melting glaciers and ice sheets, droughts, floods and other climate changes. Even the chemistry of the land and ocean is changing, with the ocean becoming more acidic thus threatening coral reefs as a result of higher carbon dioxide.

There are emerging technologies throughout the field around oceanography, which we will incorporate into oceanography, and through that convergence, we will transform oceanography into something even more magical.

As Earth warms, now because of extra CO2 we put in the atmosphere, ice will melt, and CO2 and methane will be released by warming ocean and melting permafrost.

And, at the same time, water from the surface, which is rich in oxygen, doesn't make it down and the ocean turns into a desert.

If you are scared by global warming, wait until we learn about local warming.

It's an oceanographic phenomenon that shifts in time and space on a seasonal basis.

All right, what's the consequence? The oceans probably turn purple.

Global warming fun.

Global warming is a great example.

The weather suddenly got warmer.
