[00:07] Earth's temperature climbed about one degree Fahrenheit during the last century, and is sure to climb more in this century.

[00:15] As it does, our natural environment will change dramatically. Plants and animals will be forced to adapt, move, or go extinct.

[00:24] Already, the distribution and life cycles of plants, animals and fish, are shifting in response to changes in Earth's climate.

[00:34] In the North Sea, warming water has driven commercially important fish such as cod, farther north to colder and deeper waters. In turn, more exotic, warmer-water fish have pushed into the range being vacated.

[00:47] The northward shift of the boundary coincides with a rise in temperature of nearly 2 degrees in North Sea waters between 1977 and 2001.

[00:57] If the trend continues, Atlantic cod will no longer be able to live in the North Sea by 2080.

[01:03] The heavy pressure our industrialized society puts on Earth drives climate change. Whole ecosystems are modified, forcing species to fight for survival in different surroundings.

[01:14] If we understand the rapid changes our activities force the natural world to respond to, we'll learn to make better decisions today that will determine Earth's climate tomorrow, and in turn, nature's services on which all of us depend.
