A related and updated discussion of global population and GDP increases and their effects on climate change can be found here.
2020 update: Articles citing credible studies continue to confirm dire conclusions that I previously presented. If we have such a hard time getting people to wear masks in the midst of a pandemic, how are we to address climate change where we need to achieve zero emissions by 2050?
How we live is likely to greatly change.
As I said in my post of 10/16/2018, Wind, Rain, and Climate Change, tropical storm Michael dropped about 1.5 inches of rain overnight in Norfolk, VA when I was at the Association for Applied & Clinical Sociology meeting (AACS). Although this is a significant rainfall, it should not cause flooding in most instances. However, according to Wetlands Watch, sea-level rise in Norfolk is already 1.5 feet higher (twice the global average) than in 1880. As a result, just a little rain or storm surge is a problem. I walked through some of the waterfront area the next day (Saturday, Oct. 13). Many of the low-lying streets were partially flooded, as you can see in the photos.
The following two photos show the same flood area from opposite angles. You can see that the river is over the barrier.
Here are some of the statistical highlights from my presentation. Since 1880:
- average global temperature has increased 0.8° C
- average sea-level has risen 8 inches
- greenhouse gases from fossil fuels comprise 25% of all CO2.
Although world population growth rate has declined from 2.2% in 1962 to 1.1% in 2014, world population continues to grow at a rapid rate.
Global energy demand continues to rise (2017 grew at twice the rate of 2016).
Based on known reserves and if burned at current rates:
- Coal will run out in about 100 years.
- Natural gas will run out in 53 years.
- Oil will run out in 51 years.
While we have made great inroads on infectious disease, a warming climate will reverse this trend. To address this in light of dwindling energy resources, a national health care policy should focus on:
- putting a greater proportion of resources into primary care and public health
- fewer resources on expensive tertiary care (e.g., surgeries)
- developing new generation antibiotics for resistant bacteria.
We are currently undergoing the sixth extinction in earth’s history. If this continues, the earth will see a major transition in life on the planet (possibly without humans), much as happened during the fifth extinction that killed off the dinosaurs, allowing the evolutionary development of mammals and eventually, us.
To minimize the future effects of climate change we need to carry out three multinational policies within the next few years:
- develop/implement carbon capture technologies (i.e., extract CO2 from the atmosphere and store it underground–Watch Nova video)
- dramatically reduce fossil fuel energy (via carbon taxes and other government regulations)
- improve and rapidly deploy renewable energy technologies.
Unfortunately, I do not see how this can happen given current global politics. However, whether or not fossil fuel energy reduction happens, we will be transitioning from predominately manufacturing and post-industrial societies to micro-industrial societies.
What might micro-industrialization look like? It is hard to say since how we will utilize diminished energy resources is as much a political question as it is an engineering one. A New York Times article gives us a glimpse of how micro-industrialization might start.
As much as I think renewable energy is all we can depend on, it is highly unlikely that it can replace the output of fossil fuels, at least in the near future. “Dead dinosaurs” simply produce unsurpassed energy outputs (try flying large aircraft with solar). The mass production of automobiles would end, resulting in soaring prices. We would likely allocate limited resources (not just energy) to the production of public transportation, clothing, food, and housing. Some argue for space mining as a way to increase our resources. However, this is a science fiction fantasy. Think of the costs associated with building just one space station with living quarters not much larger than a school bus. The likely reality is that we will be stuck with the resources on our rock.
Therefore, it appears that as we look back and consider the scientific evidence, large-scale industrialization is to the economy as sugar is to an organism. It provides a short-term energy boost. Unfortunately, fossil fuel energy is not sustainable because of pollution, climate change, and dwindling resources. Our great run of the last 150 years is ending and we need to implement a grand plan, soon.
Yes, this is bleak news; climate change will severely affect our youth. Many will certainly take issue with climate science and what it portends. However, for those who do, they bear the burden of proof. Saying they do not believe prevailing scientific findings is their right, but their opinions or feelings do not a rebuttal make.
