President Donald Trump withdrew the U.S. from the Paris Climate Agreement this past week. It is a sad time for U.S. leadership in the world. We should remain in the Agreement that we faithfully signed for important environmental, political, and economic reasons.
Climate change is already here — even in Iowa — and it is going to get much worse if we do not reduce our greenhouse gas emissions that are accumulating in the atmosphere and heating the planet. We recognize climate change in the Cedar Rapids flood of 2008, from which we are still recovering, and the (extremely unusual) Cedar River Basin flood of September last year. Temperatures are warmer, especially at night and in the winter. Intense precipitation is more severe and frequent. It is a wetter/warmer Iowa with more humidity in the air and greater runoff in our rivers.
At the global scale, ice is breaking and melting — in the Arctic, Greenland, Antarctica and land-based continental glaciers everywhere. Animals, which depend on the ice for fishing and hunting, like polar bears, are in trouble. Oceans are 30 percent more acidic than 50 years ago due to carbon dioxide from burning fossil fuels, subsequently bleaching coral reefs and undermining fisheries. More frequent droughts and floods affect agriculture and food supplies. Sea level is rising and already influencing real estate prices and the number of days with “clear sky” flooding in the streets in Miami. Impacts on human health, heat stroke, air quality, pollen, emphysema and asthma, and the migration of mosquitoes and ticks as vectors of disease are especially worrisome.
Politically, the U.S. is losing its credibility in the world as a stable partner whether one speaks of the Paris Climate Agreement, NAFTA, the Trans-Pacific Partnership, or NATO. Once broken, trust is hard to restore. America First means everyone else be damned, and friends can be difficult to find in times of need. Moral and ethical reasons would dictate that the richest country, which dumped more greenhouse gases into the atmosphere than any other nation, should be the first to act. I stood in Paris with representatives from the most vulnerable nations like the Marshall Islands, Kiribati, and the Maldives, who are already losing whole islands to sea level rise and abandoning ancestral homes. I listened in Paris to coastal nations like Bangladesh, Senegal, Mozambique, and the Philippines, embattled by improbable storm surge and increasingly powerful storms. And my heart cries for the children of drought and famine in South Sudan, Somalia, and Ethiopia. These vulnerable countries profited the least from the fossil fuel age, but they suffer the most.
It is not often when 194 countries agree on anything. What makes the Paris Climate Agreement unique is that for the first time, nearly every nation (rich and poor alike) agreed on an equitable “bottom-up” plan to decrease emissions and to fund the most vulnerable nations. It is certainly not a perfect agreement, and it does not go far enough to stem the tide of climate change. More will be needed.
But the U.S. will not be a party to the agreement, and that is a major economic mistake. It is quite possible that China and President Xi Jinping will step into the limelight and lead the world forward. After all, China is already the world’s leading producer of solar photovoltaic panels and wind power. Interestingly, the Chinese written word for “crisis” has two characters. One character means “danger”, and there is certainly danger in the effects of climate change, both now and in the future. The other character stands for “opportunity”. It is the economic opportunity that the U.S. will miss, which China realizes fully. Transitioning from the fossil fuel age represents a great opportunity to create jobs, wealth, and prosperity for our children and for future generations. Iowa has already benefited tremendously from wind power, turbine manufacturing, and energy efficiency. We stand to profit as well from solar photovoltaics, if we can but understand the crisis of climate change.
