Carbon dioxide levels have clearly been a large impact on our planet, especially in regards to global warming. Due to plants developing the ability to photosynthesise about 2.5 million years ago, much of the carbon dioxide was consumed, resulting in the CO2 levels being quite bellow what they are today. Due to the industrial revolution where a mass amount of new technologies were introduced, more and more fossil fuels got burned, increasing the Earth's temperature. The industrial revolution was a world changing event that lead us to be able to have basic systems we have today (just more advanced). Through the excitement of new inventions there was massive greenhouse gas emissions. The Sun's rays are getting trapped in the atmosphere, which continues to slowly warm the planet. Due to big business nowadays wanting to mass produce products to create a profit, the rate of emissions have been constantly increasing alongside the temperature. Although there is clear evidence that CO2 is causing a warming of our planet, we have to remember that climate is complex and unpredictable at points. CO2 emissions are not the only thing effecting the warming of our earth- and knowing that is one step into understanding how to better deal with the warming of our planet. I believe that humans have to take action to become more eco-friendly to ensure that we can live for a substantially long time on this planet. We should not have to resort to living on an entirely new planet because we were too lazy or not willing to take action and make our planet a better place. Though the Paris agreement did not go as planned, I believe that we should continue to plan conferences such as this to get everyone talking about the issue that is climate change in order to protect all of the species on this planet. Bettering our use of renewable energy sources can ensure for a healthier, happier, and safer world.
I agree with your statements in regards to us as a human race having to begin making changes to better our planet, in the means of CO2 emissions. The struggles we have had with making changes I feel is heavily influenced by myths that are heavily valued as facts by a large amount of society. As some myths people focus on may be "the climate has changed in the past before, as this is part of the cycle", it is true the climate has changed in the past, although only when a force was working on changing, as now humans are becoming that changing force. People may also believe that since animals are able to make adaptations that this is not a major issue, although these adaptations usually take a process of hundreds if not thousands of years and at the rate we are heading it is impossible for certain species to survive. These believed myths I personally believe is what is holding back the majority of our society from making steps in the right direction regarding climate change.
I agree with your opinions and statements with regards to the human race having to begin to take initiative with their CO2 consumptions, and taking initiative with keeping them low. Although that does contradict the Paris Accord that some countries have yet to live up to their take of dropping 2.5% by 2020; I do see ways that our own country, Canada is taking initiative. We have a real-life example that goes with your opinion here in Alberta- Our primer had recently stated that Alberta would be taking in a Carbon Tax initiative and hoping to reduce the use of fossil fuel consumption (switching to renewable resources as a source for energy) by 2020. That along with the growing need of environmentalists within the workforce- really help take your opinion into action. We need to guide ourselves away from myths that people have told us (ex: how the ozone layer can never be repaired, which is proven wrong as it is slowly repairing itself), and gear ourselves towards finding our own solutions within our communities (much like Alberta has in the example stated above).
I partially agree to what you are saying, except for the fact that Carbon Dioxide emissions are not entirely responsible for the increase in temperature. Carbon dioxide does not directly effect the ozone, instead it slows down the production of the ozone layer. But, carbon dioxide even though it has its negatives, can be partially helpful in the upper stratosphere where CO2 increases the ozone by preventing nitrogen oxide from breaking the ozone down. But I do agree that all of us here on earth need to take care of our planet to make sure it lasts, and that we do need to take steps of reducing GHG emissions and to move towards eco-friendly resources such as solar powered energy.
Carbon dioxide is an important heat-trapping greenhouse gas, which is released through human activities such as deforestation and burning fossil fuels, as well as natural processes such as respiration and volcanic eruptions. Air bubbles trapped in ice tell us that levels of carbon dioxide in the atmosphere are higher than they have been recently.
