This week’s segment looks at the influence of carbon dioxide on the record high-temperature levels this year.
Ocean carbon dioxide levels hit a new record early this month, as it was 84 degrees near the Arctic Ocean.
This is the Iowa Environmental Focus.
Temperatures rose to 84 degrees in the northwest of Russian near the entrance of the Arctic Ocean, a rural area in eastern Russia where the average high temperature is around 54 degrees this time of year.
Many locations around Russia set record high temperatures. This particular heat wave, a manifestation of the arrangement of weather systems and fluctuations in the jet stream, fits into what has been an unusually warm year across the Arctic and most of the mid-latitudes.
In the meantime, the carbon dioxide concentration in the atmosphere surpassed 415 parts per million for the first time in recorded history — the highest in at least 800,000 years, and possibly the highest levels in over 3 million years. Carbon dioxide levels have risen by nearly 50 percent since the Industrial Revolution.
These numbers altogether serve as indicators of the damages done by modern civilization to the environment and the contributions humans have made towards climate change.
