That means that in the entire history of human civilization, CO2 levels have never been this high. I am the founder of Science Trends, a leading source of science news and analysis on everything from climate change to cancer research. The Keeling Curve, showing CO2 concentrations increasing to near 400 ppm in 2013. Credit: NOAA. Reducing carbon dioxide emissions can slow and halt these changes, but it’s yet to be seen how quickly humans will proactively change in the face of a looming climate crisis. Today, in 2019, carbon dioxide concentration levels are around 410ppm. (Photo by Joe Raedle/Getty Images), EY & Citi On The Importance Of Resilience And Innovation, Impact 50: Investors Seeking Profit — And Pushing For Change, Michigan Economic Development Corporation BrandVoice, higher than it has ever been during human history, no records of CO2 rising at the current rate, We’ve seen CO2 levels rise faster in the past century than ever before in natural history. This week the World Meteorological Organization published their yearly report on the “State of Greenhouse Gases in the Atmosphere,” compiling data up to 2018. As the glaciers melt, scientists are also trying to understand how that will impact different parts of the environment from the food chain to the level of the waters in the worlds oceans. How do we put these carbon dioxide concentrations into a historical perspective? The last time the atmospheric carbon dioxide was this high, sea level was 50 to 80 feet higher than it is today and 3.6°–5.4°F warmer than pre-industrial temperatures. Pre industrial levels of ppm were about 280, and since we started burning fossil fuels heavily, they are at current levels 4. The other key concern is that humans have built our world expecting a largely static environment. According to readings from the Scripps Institution of Oceanography and the National Oceanic and Atmospheric Administration (NOAA), the amount of CO2 in the air in May 2020 hit an average … 1. Imagine you’re driving west across the country with no map, no GPS, no smartphone and in the middle of the night. CO2 is not the only driver of climate. Let's connect @trevornace, © 2020 Forbes Media LLC. The highest recorded measurement in 2018 was 415.70 ppm on May 15, 2019, higher than it has ever been during human history. The highest recorded measurement in 2018 was 415.70 ppm on May 15, 2019, higher than it has ever been during human history. Geologists and climate scientists can look at ice cores, tree rings, ocean sediment, etc. “Well-understood physics tells us that the increasing levels of greenhouse gases are heating Earth’s surface, melting ice and accelerating sea-level rise,” said Pieter Tans, senior scientist with NOAA’s Global Monitoring Laboratory. The coronavirus-related lockdowns did cause a temporary drop in CO2 emissions, estimated at 17 percent. The reading of 417 ppm is up from 414.7 ppm in May of 2019. Yale’s Environment 360 reports that … Louis Sass, a physical scientist with the United States Geological Survey, uses a tape to measure ... [+] the depth from where he is taking core samples from the Wolverine Glacier on September 06, 2019 near Primrose, Alaska. Let's connect @trevornace, © 2020 Forbes Media LLC. Carbon dioxide levels are now the highest they’ve been in human history, and likely the highest in 3 million years. On top of that, it is likely the highest concentration seen on Earth in 3 million years. In the early Phanerozoic, solar output was about 4% less than current levels. All Rights Reserved, This is a BETA experience. While volcanic eruptions previously played a significant role in increasing CO2 in the atmosphere and thus warming the planet, we know that the modern rise in CO2 is a response to burning fossil fuels. The reading of 417 ppm is likely the highest it has ever been in the history of humans on Earth. What do we do when cities become increasingly inundated with ocean water from rising sea levels? Figure showing historical CO2 compared to modern CO2. to reconstruct what our climate looked like in the past. “If we do not stop greenhouse gases from rising further, especially CO2, large regions of the planet will become uninhabitable.”. How do we put these carbon dioxide concentrations into a historical perspective? The USGS has has been studying the Wolverine glacier since 1966 and the studies show that the worlds warming climate has resulted in sustained glacial mass loss as melting outpaced the accumulation of new snow and ice. On top of that, it is likely the highest concentration seen on Earth in 3 million years. Updated 10:29 AM ET, Thu April 4, 2019 . (Photo by Joe Raedle/Getty Images). As the glaciers melt, scientists are also trying to understand how that will impact different parts of the environment from the food chain to the level of the waters in the worlds oceans. How does that change epidemiology and the spread of diseases throughout the world. As we can measure and quantify both in historical and geologic records, we can separate the relative contribution of each. The reading of 417 ppm is likely the highest it has ever been in the history of humans on Earth. So what is all the fuss about, really? The USGS has has been studying the Wolverine glacier since 1966 and the studies show that the worlds warming climate has resulted in sustained glacial mass loss as melting outpaced the accumulation of new snow and ice. We notice also that the sea level response is sometimes negative with respect to warming or cooling of the atmosphere. However, the lockdowns were too short-lived and not significant enough to alter the course of CO2 rising each year consistently on Earth. Atmospheric CO2 levels have reached spectacular values in the deep past, possibly topping over 5000 ppm in the late Ordovician around 440 million years ago. That is why scientists are concerned and increasingly sounding the alarm for where we are currently headed. If Earth has seen an order of magnitude higher carbon dioxide levels than present, why are we to worry? Note that there are huge uncertainties associated with these estimates, but the mid-range of the estimates suggests that CO 2 levels were very high during To understand past climate, we need to include other forcings that drive climate. Miami sits just 6.5 feet above sea level. CO2 is at the highest levels ever experienced in human history. I am, I am a geologist passionate about sharing Earth's intricacies with you. I am, I am a geologist passionate about sharing Earth's intricacies with you. Our infrastructure, agriculture, areas of concentrated populations, and energy systems are all built to serve humans in a relatively static environment. However, as the yearly May benchmark was released it appears to have done little to slow the ever-increasing rise in carbon dioxide in the atmosphere. In this graph we notice that higher sea levels generally correspond with periods of warming while lower sea levels marry generally with periods of cooling. I received my PhD from Duke University where I studied the geology and climate of the Amazon. Humans are at their best when we’re able to predict the outcomes of our actions, however, the current rate of CO2 rise leaves scientists worried as there is no blueprint or map of where we’re headed in the coming decades. We are “driving blind” into an unknown climate future.
