This winter is shaping up to be a scary one. There has not been a substantial cold snap where the ambient temperature remains below zero for a week or more. We need that to suppress the insects living in the ground that feed on our plant life in the garden and yard when it gets warmer. Cold weather is also the best time to prune fruit trees.
It’s no surprise it’s getting warmer.
Atmospheric CO2 concentration hit 413.95 ppm at the Mauna Loa Observatory in Hawaii in December 2020. In my birth year of 1951 the global average was 311.80. There is a direct correlation between atmospheric CO2 and planetary warming. Our best hope is it’s not too late to mitigate rising CO2 levels.
According to NASA, 2020 tied 2016 as the warmest year on record in global average surface temperature. According to this chart, the rise in global surface temperature is in an accelerating upward trend since the baseline period of 1951-1980.
In the general election of 2020, Americans took a necessary step toward climate action by electing Joe Biden and Kamala Harris, the president and vice president willing to examine and understand the science of climate change and take action. Because Biden served as Barack Obama’s vice president, he knows what to do. It would have been better to elect a stronger majority in the legislative branch of the federal government, yet we didn’t. The majority we have will serve as we can’t wait two years to increase the majority of science believers in the midterms.
The United States rejoined the Paris Agreement within the United Nations Framework Convention on Climate Change. Like the election, it’s a beginning step. The Paris Agreement is flawed, yet it is difficult to see how the world makes progress toward reducing greenhouse gas emissions without the kind of cooperation it envisioned. Our country simply must be part of the discussion.
As a single citizen, or a small family, it is difficult to see how to help. We can and should reduce our personal carbon footprint, especially by doing things that don’t require a lot of capital: use less hot water, set the furnace thermostat lower, run the air conditioner at a higher temperature, use less gasoline and natural gas, eschew air travel and long automobile trips. The coronavirus pandemic kept many of us at home and that had a direct impact on greenhouse gas emissions. Eventually we will learn to live with the coronavirus and when we do, the need to control emissions will remain.
These are scary times. One view is there is nothing to be done about all this. The apocalypse is coming and the best we can do is mitigate its impact on us as individuals. It’s a vision of doomsday preppers, isolated and remote enclaves of the wealthy, and an attitude of preserving self as the catastrophe hits. I reject this view. We are stronger together and together we should remain in mitigating the impact of climate change.
It also seems important to focus on the big picture. Political leadership is required to make progress. For some of us, such leaders won’t be as bold as we want or feel is needed. We can’t relent on our politics.
Iowa has had its recent climate-related difficulties, floods in 1993 and 2008, tornadoes, straight line wind, a derecho, and drought. At the same time row crop yields were decreased due to climate change, as in the 2012 drought, a new, diverse agriculture remains possible because of our growing conditions. Gardeners like me contribute to resolving climate change by growing more of our own food. The process would be scalable if the importance of growing more local food were more generally accepted. We do what we can with local resources and conditions. We could do more.
Scary as it is, we can’t get depressed. It is human nature to be hopeful and hope is one of our most powerful attributes. It is important to be realistic about where we stand on mitigating the effects of greenhouse gases. For the next years, the picture isn’t going to be pretty. We can’t give up. We must persist in the effort to make our communal lives better. That’s what I plan to do.
