One change leads to another, and, like falling dominoes, these changes affect the lives of many plants and animals, including humans.]]> 2017-01-26 15:38:14 UTC https://padlet.com/ketleyj/7dahjxujy5m5/wish/149635763 ketleyj https://padlet.com/ketleyj/7dahjxujy5m5/wish/149640087 When things change, they have trouble adapting. For instance, changes in ocean currents affect fish and other sea creatures whose life cycles depend on the temperatures, movement, and salt content of water.]]> 2017-01-26 15:47:03 UTC https://padlet.com/ketleyj/7dahjxujy5m5/wish/149640087 ketleyj https://padlet.com/ketleyj/7dahjxujy5m5/wish/149640950 On land, global warming will cause forest boundaries to change. As Earth warms, trees will be able to grow farther north into the tundra and higher up the mountains. But it will take time for these new forests to mature so that they can support the animals that depend on them.]]> 2017-01-26 15:48:44 UTC https://padlet.com/ketleyj/7dahjxujy5m5/wish/149640950 ketleyj https://padlet.com/ketleyj/7dahjxujy5m5/wish/149642175 Water from melting snow feeds the rivers and keeps the forests healthy.

warming, changing our ways can slow down
the warming trend. But can we keep up with
the speed of climate change? That’s another
reason scientists are worried.]]> 2017-01-26 15:56:42 UTC https://padlet.com/ketleyj/7dahjxujy5m5/wish/149644661 ketleyj https://padlet.com/ketleyj/7dahjxujy5m5/wish/150250893 2017-01-30 15:02:36 UTC https://padlet.com/ketleyj/7dahjxujy5m5/wish/150250893 ketleyj https://padlet.com/ketleyj/7dahjxujy5m5/wish/150256905
The Earth's climate has changed throughout history. Just in the last 650,000 years there have been seven cycles of glacial advance and retreat, with the abrupt end of the last ice age about 7,000 years ago marking the beginning of the modern climate era — and of human civilization. ]]> 2017-01-30 15:14:39 UTC https://padlet.com/ketleyj/7dahjxujy5m5/wish/150256905 ketleyj https://padlet.com/ketleyj/7dahjxujy5m5/wish/150267407 The number of record high temperature events in the United States has been increasing, while the number of record low temperature events has been decreasing, since 1950.

Mass coral bleaching results in the starvation, shrinkage and death of the corals that support the thousands of species that live on coral reefs.
