Is climate change human made? There’s been a lot of research and reports about climate change over the years and I don’t blame you if you don’t want to read them all. So here’s in 3 minutes what we know for sure.
It all started in 1998 and an ice drilling project was undertaken in the Russian Vostok station in Antarctica. The project yield at the deepest ice score ever recovered, giving access to ice that was 420,000 years old and a depth with 3,623 meters. It’s supplied data about atmospheric composition and climate from for climate cycles. So here’s how it all works.
The formation of the glaciers results from the transformation of water in the ice. During this process, which can last thousands of years, sediments, air and rocks are stuck into the ice making millions of layers, one above the other in chronological or over the time the glacier becomes a million page history book or the last chapter on the top.
The deeper you drill, the older compounds are. The ice core gave access to climate data including local temperature, precipitation rate, wind strength, et Cetera, but also, and this is what we’re most interested in here, the high score provided direct records of past changes in atmospheric trace gas composition thanks to their and trapped air conclusions. Then it was possible to determine the levels of carbon dioxide or co two and methane ch four and a given time.
So here’s what global temperature and atmospheric concentrations of carbon dioxide and methane looked like over four climate cycles spanning 420,000 years. You can clearly see the for climate cycles and you can also see they have very similar spikes and patterns. There’s clearly a relationship between temperature, carbon dioxide and methane. The upper and lower boundaries of these three variables are tightly constrained, which is typical of a self regulating system.
Body is also a self regulating system and does something similar in a way. When you exercise your body sweats as a way to regulate its temperature well on earth. When concentrations of carbon dioxide and methane go up. Global atmospheric temperature goes up to now, here’s what happened with the concentration of atmospheric CO2 since 1960 it increased by about 70 parts per million. That is more than one parts per million each year and it getting significant human influenced in a self regulating system of earth since the beginning of the industrial revolution as this concentration is now way over the upper boundary noted during the last 420,000 years.
And as the Europe seems to be a self regulating system, well we can expect the global temperature to increase as well. And we are already seeing is worldwide. Since the Vostok researchers published more recent eyes, scores were performed by the European project for ice coring in Antarctica or Epica they provided for the last 800,000 years and confirmed the bindings in Boston. So as the intergovernmental panel on climate change simply puts it in their 2013 report, human influence on the climate system is clear and we can safely say that we human beings are responsible for climate change. And that’s actually really good news because we can cause it. You can also change it. Today we have the knowledge, tools, technology, and resources to address climate change.
We just need to own it and take responsibility. If you enjoy this video, please like share or comment so we can bring more awareness to climate change.
