Knowing that carbon dioxide can make the atmosphere increase in temperature, can explain what causes many problems like ice melting, water levels rising, more natural disasters, warmer temperatures during the winter, warmer ocean temperatures, and many more things.  Even though all these consequences of climate change are affecting the earth negatively, they led to the Paris Agreement on Climate Change, which can help people, animals, our atmosphere, and the entire planet. ]]> 2021-05-09 15:00:07 UTC https://padlet.com/cklein41_1/8rcls00a559famxd/wish/1506509138 cklein41_1 https://padlet.com/cklein41_1/8rcls00a559famxd/wish/1506509911 Scientists were concerned about how the carbon dioxide levels were in the atmosphere in the 1950’s.  Compared to millennia on the graph, the carbon dioxide levels have never been above the line, but in 1950, it crossed the line.  The line represents the maximum amount of carbon dioxide that should be in the atmosphere.  The x axis shows the years before present day, and it goes back 800,000 years ago.  On the y-axis, it shows the levels of carbon dioxide.  The significance of this data is it shows how bad climate change is right now.  There weren’t any actions taken until the Paris Agreement was created. Some ways to stop climate change are to unplug computers, TVs, and other electronics, buy organic food, fly less, and switch to an electric or plug-in hybrid vehicle.]]> 2021-05-09 15:00:43 UTC https://padlet.com/cklein41_1/8rcls00a559famxd/wish/1506509911 cklein41_1 https://padlet.com/cklein41_1/8rcls00a559famxd/wish/1506511632 Donald Trump decided to withdraw from the Paris Agreement on November 4, 2020.  Trump’s reasons to leave the agreement were that it would cost America 2.7 million lost jobs by 2025.  The World Resources Institute said that calculation isn’t correction.  Another reason is that he thought it was just a small temperature change.  If the Paris Agreement achieved its goals, then the atmosphere’s temperature would decrease nine-tenths of one degree, which according to NASA, is a dramatic change to the planet because it would be 20% of the increase we’ve already seen.  Another reason is it has a negative impact on the economy.  He thought that remaining in the agreement would cost almost 3 trillion dollars.  However, according to the Resources of the Future, the U.S. could reach its goals with a much lower carbon tax rate over less time.  He also thought there would be blackouts and brownouts, which is not true because inclement weather causes blackouts and brownouts, not from a lack of adequate power.  The last reason is he thought it would be billions and billions of dollars.  All the reasons he said why he withdrew from the agreement are answers based on his beliefs, not based on facts.  After the withdrawal, many countries were very disappointed with withdrawing because this shows that Trump doesn’t want to fight climate change and wants to help our planet.  Countries like Canada, France, Spain, Brazil, Japan, and many other countries said that withdrawing from the Paris Agreement can cause negative impacts.]]> 2021-05-09 15:02:12 UTC https://padlet.com/cklein41_1/8rcls00a559famxd/wish/1506511632 cklein41_1 https://padlet.com/cklein41_1/8rcls00a559famxd/wish/1532027084 On December 12, 2015, 196 countries including China and The United States signed the agreement in Paris and 196 parties at COP 21 adopted the Paris Agreement.  The Paris Agreement against Climate Change is an accord that is trying to address climate change and its negative effects.  The plan works on a 5-year cycle to limit climate change and by 2020, countries submit their plans for climate change known as NDCs (Nationally Determined Contributions).  NDC’s are long term goals from each country to limit climate change.  Iran, Turkey, and Iraq did not ratify the Paris Agreement because they had other plans on their own.  The purpose of the agreement is to decrease the atmosphere’s temperature from 2 degrees Celsius, to 1.5 degrees Celsius and to reach greenhouse gas emissions.]]> 2021-05-17 16:20:54 UTC https://padlet.com/cklein41_1/8rcls00a559famxd/wish/1532027084 cklein41_1 https://padlet.com/cklein41_1/8rcls00a559famxd/wish/1532200248 When Joe Biden became president, he and Kamala Harris rejoined the agreement on February 19, 2021.  They wanted to rejoin the agreement again because it shows the world that the United States is addressing climate change again and recognizing that climate change is a serious issue.  The world was very happy that the United States rejoined the agreement, and Dr. M. Sanjayan, chief executive of Conservation International, “President Biden’s action today is certainly a step in the right direction.”  Positive impacts with rejoining the Paris Agreement is that since the United States is the second-largest carbon dioxide emitter, the Biden administration can reduce greenhouse gas emissions under the Paris Agreement and they can do more advanced research and develop more solutions to help protect families.]]> 2021-05-17 16:55:18 UTC https://padlet.com/cklein41_1/8rcls00a559famxd/wish/1532200248
