Global warming is the overall increase in temperature of the earth's atmosphere. Each year, temperatures are rising mainly from the increase of greenhouse gas emissions (CO2, N2O, O3, etc.). It was reported that out of all the years, 2018 was the warmest year for oceans. This logically implies that we are polluting the environments more and more each year, and that 2018 was a rough year for not just our oceans, but with our land too.
According to this video water vapor keeps the most amount of heat from leaving the atmosphere however since the atmosphere can only hold a limited amount of water vapor before it rains it is not the main cause of global warming. The greenhouse gas that raises the global temperature the most when released is sulphur hexafluoride. Not much sulphur hexafluoride has been emitted yet and does not compose much of the atmosphere and therefore is not the main reason for the rise is temperatures. The greenhouse gas that is the main culprit of the Earth's rising temperature is carbon dioxide as it has raised Earth's temperature the most due to the large amount of CO2 in the atmosphere.
This page outlines The Paris Agreement which outline countries efforts to combat climate change and keep the globe's temperature well below the 2 degree projected increase. To summarize, it is few regulations to make sure countries take responsibility and are responsible for the changes in the climate. Below, I copied a detailed report on what the agreement entails.(copied from the United Nations handbook on the UNFCCC). It also interesting that United States pulled out of the Paris Agreement despite being a primary source of greenhouse gas emissions
Long-term temperature goal (Art. 2) – The Paris Agreement, in seeking to strengthen the global response to climate change, reaffirms the goal of limiting global temperature increase to well below 2 degrees Celsius, while pursuing efforts to limit the increase to 1.5 degrees.
Global peaking (Art. 4) –To achieve this temperature goal, Parties aim to reach global peaking of greenhouse gas emissions (GHGs) as soon as possible, recognizing peaking will take longer for developing country Parties, so as to achieve a balance between anthropogenic emissions by sources and removals by sinks of GHGs in the second half of the century.
Mitigation (Art. 4) – The Paris Agreement establishes binding commitments by all Parties to prepare, communicate and maintain a nationally determined contribution (NDC) and to pursue domestic measures to achieve them. It also prescribes that Parties shall communicate their NDCs every 5 years and provide information necessary for clarity and transparency. To set a firm foundation for higher ambition, each successive NDC will represent a progression beyond the previous one and reflect the highest possible ambition. Developed countries should continue to take the lead by undertaking absolute economy-wide reduction targets, while developing countries should continue enhancing their mitigation efforts, and are encouraged to move toward economy-wide targets over time in the light of different national circumstances.
Sinks and reservoirs (Art.5) –The Paris Agreement also encourages Parties to conserve and enhance, as appropriate, sinks and reservoirs of GHGs as referred to in Article 4, paragraph 1(d) of the Convention, including forests.
Voluntary cooperation/Market- and non-market-based approaches (Art. 6) – The Paris Agreement recognizes the possibility of voluntary cooperation among Parties to allow for higher ambition and sets out principles – including environmental integrity, transparency and robust accounting – for any cooperation that involves internationally transferal of mitigation outcomes. It establishes a mechanism to contribute to the mitigation of GHG emissions and support sustainable development, and defines a framework for non-market approaches to sustainable development.
Adaptation (Art. 7) – The Paris Agreement establishes a global goal on adaptation – of enhancing adaptive capacity, strengthening resilience and reduction of vulnerability to climate change. It aims to significantly strengthen national adaptation efforts, including through support and international cooperation. It also recognizes that adaptation is a global challenge faced by all. All Parties should engage in adaptation planning and are expected to submit and periodically update an adaptation communication on their priorities, implementation and support needs, plans and actions. Developing country Parties will receive enhanced support for adaptation actions.
Loss and damage (Art. 8) – The Paris Agreement significantly enhances the Warsaw International Mechanism on Loss and Damage, which will develop approaches to help vulnerable countries cope with the adverse effects of climate change, including extreme weather events and slow-onset events such as sea-level rise.
In this article, we see 6 different and positive stories about climate change in 2018. One of these is about Chernobyl, one of the worst nuclear accidents to date and how it could’ve been a good thing for the environment. In fact, Forests have reclaimed the entirety of the Chernobyl Exclusion Zone and it is now home to an amazing diversity of wildlife. The ongoing expansion of Chernobyl’s forests means more carbon is becoming incorporated into the trees which takes away from fossil fuels in the atmosphere. Additionally, the central part Chernobyl is now home to a major new solar farm development with the possible development of a wind farm. Thus, turning an atrocity into a positive point for mankind as a whole.
Social media can be used for personal entertainment but what if we use that platform to inform others on what is the green house effect and how we can reduce our carbon footprint. But you must start with yourselves and from there you will be an example for others and they will start to reduce their carbon footprint and person by person we can all help the earth as well as the future generations to come.
As we live on land, it may not seem to concern us, but the ocean covers 70% of the Earth's surface. The ocean plays a huge role regarding the environment. It soaks up energy (heat) and distributes it around the Earth. The top few meters of the ocean stores as much heat as the Earth's entire atmosphere. This is a problem because, if the ocean gets too warm, then the animals and plants that live in it must adapt, or die.
"Effects of Global Warming"
Although this is actually a highly simplified list of cause and effects of both global warming and climate change, it generally talks about the idea of melting ice caps, glaciers, and sheets. It also lists many impacts that scientists have ALREADY DOCUMENTED simply within the past few years. Something that wasn't mentioned in class was how animals may migrate to other regions in order to survive, while other animals (jellyfish, mosquitoes, bark beetles, etc) continue to thrive due to rising temperatures. Bark beetles specifically, are damaging over millions of forested acres.
In this recent news article, it talks about how a coffee researcher said that climate change is making the temperature increase, meaning less rainfall which is said to threaten to extinct coffee species in the near future. It is said that this is important because some Countries such as Ethiopia are the biggest coffee exporter in Africa and around 15 Million people in Ethiopia are involved in coffee production.
This site has a bunch of different climate change comics including one about how coal can’t be burned without creating carbon. The politician says that it doesn’t matter what happens, economic bottom line is more important. This shows how we don’t really care about the environment because we are too focused on money and economy.
