But scientists have found that if coral is in only 1 degree C higher that the the warmest temperature coral can survive in, it starts becoming stressed. When coral is stressed, it can become bleached from losing algae.]]> 2020-02-17 20:56:56 UTC https://padlet.com/msimpson221/do2orh74tcyy/wish/446520500 By how much have human activities increased amounts of greenhouse gases? msimpson221 https://padlet.com/msimpson221/do2orh74tcyy/wish/446520615 Scientists say that ever since the Industrial Revolution in the 1800s, the oceans have drawn in 525 billion tons of carbon dioxide. When the oceans dissolve this amount of CO2 , the water becomes more acidic by 30% (Bennett). Greenhouse emissions from the US have been decreasing since the mid 2000s. According to the EPA, the amount of greenhouse gases produced by humans is over 35% (Climate).]]> 2020-02-17 20:57:24 UTC https://padlet.com/msimpson221/do2orh74tcyy/wish/446520615 Can we make oceans more basic? msimpson221 https://padlet.com/msimpson221/do2orh74tcyy/wish/446520680 Scientists have thought that the natural buffering of oceans(chemicals from rocks flowing into the oceans from rivers) would be enough to save the oceans. But it turns out that the acidity is dropping too quickly for the buffering to occur (Bennett). In the Netherlands, a scientist has tried using olivine in seawater, but has found that nickel poisoned organisms (Klein).]]> 2020-02-17 20:57:43 UTC https://padlet.com/msimpson221/do2orh74tcyy/wish/446520680 Review of “Acidic Seas: How Carbon Dioxide is Changing the Oceans” msimpson221 https://padlet.com/msimpson221/do2orh74tcyy/wish/446521663 By Mary Simpson]]> 2020-02-17 21:01:31 UTC https://padlet.com/msimpson221/do2orh74tcyy/wish/446521663 Author's Purpose msimpson221 https://padlet.com/msimpson221/do2orh74tcyy/wish/446521887 The author’s purpose is to inform readers about the negative effects of carbon dioxide and other greenhouse gases on the Earth.]]> 2020-02-17 21:01:56 UTC https://padlet.com/msimpson221/do2orh74tcyy/wish/446521887 Major Science Concept msimpson221 https://padlet.com/msimpson221/do2orh74tcyy/wish/446522145 The main concept is that greenhouse gases, like carbon dioxide, change the acidity of oceans. ]]> 2020-02-17 21:02:19 UTC https://padlet.com/msimpson221/do2orh74tcyy/wish/446522145
