Views of the natural environment & climate change

If we do nothing we will make our biosphere inhospitable and run out of resources. If we act now, world GDP will have to shrink, dramatically. Black Rock is trying to cut our future losses.

Australia’s leaders put their own interests ahead of those who they represent, even to the extent that much of the country suffers a conflagration.
And the stark reality is that this is just the early stage result of climate warming.

This is one example of how the sixth extinction is playing out. Although this sounds contradictory, the turtles swim further north during the summer, given warmer water temperatures. However, temperatures drop below what the turtles can withstand as winter arrives.
The waters off Cape Cod and the Gulf of Maine are warming twice as fast as the oceans, for reasons not yet understood.

Portland’s air could improve. It’s much dirtier than it was 10 years ago. Too much development. We just can’t have it all.
On Monday, the United Nations Climate Action Summit gets underway in Madrid, Spain. A just released U.N. report found that we are not making very good progress towards keeping global temperature rise below 1.5⁰ C by 2050.
This is because global warming is not a linear process, but rather an exponential one; the planet is warming at faster rates over time. We are reaching what some social scientists have called a “tipping point.”
This can also be applied to the natural sciences. For example, wild fires put particulate in the air which eventually settle on glaciers. Now, in addition to warmer temperatures causing ice melt, there is a second factor, particulate, which absorbs additional heat. Another example is that warmer air not only melts the tundra’s
permafrost, but as it does, methane, a much stronger greenhouse gas, is released, further warming the planet.
The basic cause of climate change is too many people producing too much GDP with fossil fuels. The only very unfortunate solution is to stop using fossil fuels and transition to renewable energies. Since these cannot provide as much energy as fossil fuels in the foreseeable future, post-industrial societies would have to transition to micro-industrial production. This would entail giving up many of our amenities and creature comforts that we have become so used to over the past 100 years. But you and I are not going to do it. Buying a Prius just won’t cut it. The only way this can be done is by inter-governmental cooperation among the G20 countries. What we can do is pressure our political leaders.
Watch any of the business news and what do you see? All the emphasis is on growth; very little attention is paid to environmental issues unless it’s regarding regulations. As I walk down along Commercial Street in Portland, Maine, the renaissance of the last 15 years continues. High-rise buildings proliferate, some of which have condominiums ranging from about $500k to $2.5m. Though a small city, Portland has diversity, it has restaurants that can compete with those in Boston and New York, it has investment houses, and it has an outstanding art museum. All this takes energy to construct and maintain. Sad to say, this is not sustainable, not here, certainly not in London, New York, or Beijing.

There are two theories about the decline of the Easter Island native people. The first is ecocide. They cut down or burned all the trees for farmland and moving the statues they built, thus collapsing their ecosystem. The second being, success, they learned to accept less since rats, inadvertently brought to the island on the original explorers’ canoes, thrived by eating the seeds and seedlings of the island’s trees. As a result, human population declined, but the remaining people survived by eating the rats and fewer vegetables. They were adaptive. Wow, such success!
Fast forward to today and our global ecosystem faces a similar risk. As just one example, a scientific publication, reported in the The Guardian, found a 29% decline in bird populations since 1970. Perhaps this is partially due to the insect apocalypse. Hello, is anybody out there? And just as the Easter Islanders could have saved their ecosystem, regardless of which theory is true, they simply accepted their worsening new “normals.” Not us you say? Well, today the United Nations Climate Action Summit is meeting and the president of the United States is elsewhere pandering to his base. Instead, we have a teenager, Greta Thunberg, addressing the body with stern remarks, She castigated world leaders about doing little to alleviate fossil fuel emissions. Then there is the world climate strike, again with youth at the forefront, taking place around the globe.
Unfortunately for us, it very much looks like humanity will accept and adapt to dramatic population decline and scraping by with less. As I have discussed elsewhere, humanity will indeed have to adapt to less, much less. However, if we were to act now we could minimize the effects of climate change, even though these will worsen. But this is unlikely. Shaming adults will have only minimal effects on industrial production. China and India, among other countries, continue burning coal. Auto and aircraft emissions, while cleaner than in the past, are on the rise, due to larger vehicles and increased traffic. Hello, is anybody out there? (Hmm, they must be on another app.)
Humans are making hurricanes worse, as reported in the New York Times. In fairness to us, just imagine when we figured out how to build furnaces and other machines that could harness all that pent up energy in fossil fuels. Wow! All the stuff we could produce. We built better shelter, increased food production, could move us and freight longer distances in far less time (oh, there are a few labor and social issues, but we don’t need to belabor those here). What’s not to love? Well, there are downsides. Human population rapidly increased requiring more fossil fuel energy. Along with this was an increase in our wants, requiring more, you guess it, fossil fuel energy. The results are warming temperatures, expanding landfills, ocean and (somewhat less) air pollution, sea-level rise, more extreme weather, and the sixth extinction of species.
Today we are faced with a choice. Go to negative carbon emissions (i.e., no fossil fuel use and carbon recapture) by 2050 or so or go on as we are doing and run out of resources within the next hundred years, along with the loss of much humanity. It’s a formidable societal “addiction” requiring policymakers willing to risk their careers. You can read more about this elsewhere on my site.
Either way, the earth will survive just fine (at least for the next 500M years).
Living underground, the iridescent Great Black Wasp pollinates flowers while feeding itself, and removes plant pests while feeding its young making it a great friend to gardens and fields. They keep the grasshopper and cricket
populations under control. This rather unaware grasshopper on the right is feeding in the same bush as the wasps.

Apparently the Praying Mantis thinks so. Or maybe it’s poised to grab an insect (or Humming Bird). Whatever the reason we found one near my sister’s family home in Connecticut. The various Mantis’ are humanity’s friends since
they eat many of those insects that eat our crops. Load your garden up with them. They are members of the cricket/grasshopper family. You can read more about our Mantis friends at It’s Nature.
The IUCN Red list of threatened species shows this dragonfly as of least concern for extinction–one of the lucky ones. However, according to Wikipedia:
The decline [in many insects] has been attributed to habitat destruction caused by intensive farming and urbanisation, pesticide use, introduced species, climate change, and artificial lighting. The use of increased quantities of insecticides and herbicides on crops have affected not only non-target insect species, but also the plants on which they feed. Climate change and the introduction of exotic species that compete with the indigenous ones put the native species under stress, and as a result they are more likely to succumb to pathogens and parasites. While some species such as flies and cockroaches might increase as a result, the total biomass of insects is estimated to be decreasing by about 2.5% per year.
