Vacation Time & Climate Change News

 

I am sitting outdoors for the 2^rd evening in a row enjoying the warm air and the sights and sounds of a busy river front at Sault St. Marie, Michigan. We camped here just downstream from the Soo Locks alongside the St. Marys River watching the comings and goings of the large freighters plying the cool and clean water. We have camped many times at the Sault, but never has the weather been this warm.

One of the pleasures in sitting along the river is watching the sun turn from its brilliant yellow afternoon brightness to a muted red color as it moves toward the horizon. However, it is a bit sobering to understand that the red color stems not from some natural occurrence as the sun marks the passage of time, but rather results from the smoke and wildfires that are burning out of control in the western US. The fires are prompted by the unusually dry conditions in California and elsewhere in the west and have nothing to do with forest maintenance and everything to do with climate change.

The forest fires that cover thousands of acres now provokes the smoky air in several parts of the west. The ongoing air pollution has added to the woes of those who have recently contracted Covid 19. As we might have guessed, the pulmonary distress from Covid has been found to be more severe for those who are forced to breathe the polluted air near the firestorm areas. Disasters really do multiply when things go wrong.

The red sun reminds of the recent announcement from the United Nations Committee on Climate Change that things are getting worse, not better. The August 2021 sixth report compiled by an impressive coterie of scientists concluded that time to correct the ills of increasing air pollution is slipping away from us. The report projects that in the coming decades climate changes will increase in all regions.

The report is at its heart a scientific assessment of the earth’s response to the continuously increasing amount of carbon dioxide that humans release to our atmosphere. The data shows that even if we achieve net zero emissions of carbon dioxide soon, we will still have excessive heat and the consequent insults of fire, flooding, drought, storms and so forth in regions all around the world. The amount of air pollution we have already released will cause an increase in temperature of 1.5°C in the next decade.

Here are a number of conclusions from the report and press release.

“Each of the last four decades has been successively warmer than any decade that preceded it since 1850….and there will be increasing heat waves, longer warm seasons and shorter cold seasons.”

“Climate change is intensifying the water cycle. This brings more intense rainfall and associated flooding, as well as more intense drought in many regions. Climate change is also affecting rainfall patterns. In high latitudes, precipitation is likely to increase, while it is projected to decrease over large parts of the subtropics.”

 “Coastal areas will see continued sea level rise throughout the 21st century, contributing to more frequent and severe coastal flooding in low-lying areas and coastal erosion. Extreme sea level events that previously occurred only once every 100 years could happen every year by the end of this century.  Further warming will amplify permafrost thawing, and the loss of seasonal snow cover, melting of glaciers and ice sheets, and loss of summer Arctic sea ice.”

Recently, and for the first time in recorded history, it has rained on the Greenland ice shield instead of snowing.The report provides a terse summary. “This is a code red for humanity.”

Michigan has experienced our share of environmental disasters resulting from climate change and more is expected in the coming months and years. The flooding in Detroit, higher lake levels and decreasing shore lines at our Great Lakes and temperature increases like that in the western Upper Peninsula that has already warmed a whopping 2.7 degrees Fahrenheit since 1951. All the Great Lakes have suffered insults due to climate change. Chief among these has been algal growth that has dire consequences for water quality thereby affecting wildlife and drinking water for humans. Activists have been urging Michigan’s Governor Whitmer to stiffen resistance to the fossil fuel industry by eliminating give-aways sought for pipe lines and to increase the amount of required renewable energy beyond the measly goal of 15% by 2050.

A small measure of optimism can be taken from a close reading of the report. First is the impressive array of human talent that has been brought together for the work. Two hundred thirty-four leading climate experts participated in the conducting the studies and prepared the resulting report. These men and women came from 195 nations and represent humanity’s best thinking on the subject.

 The press release about the report indicates that human actions still have the potential to determine the future course of climate. The evidence is clear that carbon dioxide (CO2) is the main driver of climate change, even as other greenhouse gases and air pollutants also affect the climate. “Stabilizing the climate will require strong, rapid, and sustained reductions in greenhouse gas emissions, and reaching net zero CO2 emissions. Limiting other greenhouse gases and air pollutants, especially methane, could have benefits both for health and the climate.”

So, the future is in our hands. The question is whether we have the will to implement the changes needed to assure the future for our children. Those of us in Michigan should contact both our state and national representatives to let them know that now is the time we want action on climate change remedies.
