The One Degree Factor Group 2: Regime Change in the Pacific
“Detectives usually break mysterious cases when they first see the connections among seemingly unrelated clues. Consider these: Dust clouds are building high over the Atlantic. An entire population of caribou is declining, their numbers dwindling, while in the oceans, other species are being pushed to the limits of their physical survival. A respiratory illness, once uncommon among children in Trinidad, is now widespread. Amazingly, many scientists now believe these disparate phenomena may be linked to global climate change.”
Each group will explain what happened in their section of the video.
· What was the event that was occurring?
· How did it link to global climate change?
· What will be the impact of this?
Did you know 70% of the Earths surface is water? Also half of the water is the Pacific Ocean. Well both of these statements are true. Over time climate change has been getting worse so the number of organisms living in water are decreasing. For example the krill's and zooplankton populations are crashing.

Every two to three decades, the pacific ocean does a temperature change technically like a flip flop between cold temperatures and hot temperatures. Scientists have discovered this news recently. Pacific Decadal Oscillation is what scientists call this pattern. Scientists also call warm water positive water, and cold water negative water. Warm water surfaces have thickened between the 1970s and the 1990s.

When the water near the coastline gets warmer, organisms such as zooplankton die. Also when water gets warmer further off the coast, more organisms die. This is called Regime Change in the Pacific.

Regime Changes in the Pacific are temperature changes that effect habitats and hurt the food web. This changes the temperature in water dramatically. Sea organisms are endangered by this. Many animals will go extinct, and many will not. Animal life will not go on if many kinds of animals die. An example is if zoo plankton go extinct krill's will die of starvation and soon fish will die. When fish die many animals that live on fish will die and so on.

Climate change is getting worse. Crabs are so sensitive to temperature change that even a 2 degree temperature change will kill them. Marine Biologists have latched crabs up to heart rate monitors and placed then in water. Slowly water gradually rises in temperature. After about a 2 degree water change, crabs started to crash. This proves that some organisms are already at their max. The Marine Biologist that experimented on the crabs' name was Bill Peterson. What inspired Bill to become a Biologist was when he was a kid he was so interested in animal life. Climate change has also effected sea coral. The sea coral used to be very colorful and full of life, but now it is dieing from African dust coming traveling to the Americas and getting into the water causing sea coral to loose its color. The organisms that live in the sea coral are starting to die off.

Good Job explaining the Pacific Decadal Oscillation.
