Mr. Trump, the Climate Change Loner

President Emmanuel Macron, France, tried this week during the visit of the president of Trump to Paris to reverse his decision to leave the global agreement on the American score on Climate Change, signed in December 2015 and ratified by 153 countries. It was a futile exercise, because he had to know it would be.

And in any case, it is likely to make sense because there is no chance that it reaffirms President Barack Obama’s commitment to significantly reduce US greenhouse gas emissions. Or seeks to restore the leading role that Obama held and M. Trump has abdicated.

Apparently M. Trump had hoped for some support from other major fossil fuel producers such as Russia and Saudi Arabia.

It was not imminent, the encouragement of those who feared (and still fear) that M. Trump’s betrayal of US commitments would ensure that other countries could also relax.

The unresolved question is whether the objectives set out in the Paris agreement can be reached without the participation of the United States.

To summarize briefly, the agreement sought to limit the rise in atmospheric temperatures to 2 degrees Celsius above pre-industrial levels and 1.5 degrees if possible.

To that end, Obama has pledged to reduce greenhouse gas emissions from America from 26 to 28 percent by 2025, largely due to increased fuel consumption for cars and light trucks, Oil in methane and gas emissions and new rules governing news and old coal plants.

These are the same measures that M. Trump, through various orders, instructed his two principal lieutenants of the war against science and mental health – Scott Pruitt to the Environmental Protection Agency and the Department of Ryan Zinke interior – Delay, check or eliminate completely.

Additional instructions were issued to increase the production of fossil fuels – coal, oil, and natural gas – that are the main creators of carbon dioxide. The two men took up this task with rapid and evident pleasure.

One wonders what might change the mind of M. Trump. It seems impervious to the widely accepted science of global warming, and quite impressed by the evidence that jobs promised to his disciples that they are not dying in such industries as coal mining, but in renewable energies such as wind and solar.

Perhaps a giant iceberg that was freed from Antarctica will ring a bell. Paration may or may not be related to climate change, and that does not itself generate sea level, since the platform was already sitting in the water.

But shelves impede terrestrial glaciers, and when shelves go, glaciers tend to follow. In any case, nature has sent a message.

A more promising scenario is that one day M. Trump will awaken to the fact that the leaders of the world, who have often become demonstratively, look at him with astonishment and consternation.

In environmental issues, it transforms the United States into an outcast. That alone in the world seems to be in the White House.

But we can not bet on that either. We can expect, however, that the world will continue to build, and that market forces and the march of technology will arrive at a future of clean energy that M. Trump seems unable to embrace.
