The climate picture worsens
As global warming continues, President Trump wants to burn fossil fuels with an arsonist’s glee.
That means trouble. Glaciers already are melting. The shrinking ice cap could mean an ice-free Arctic in the summertime by the end of the century, a reduction that many scientists believe fuels a feedback loop: The less ice there is, the more solar energy the Arctic absorbs, increasing the water temperature and reducing the amount of ice still farther. That phenomenon, experts warn, will likely skew the path of the jet stream with profound climate impacts across the northern hemisphere.
Worse, the melting of glaciers raises the level of the ocean. The ice sheet covering Greenland has been melting at an increasing rate since 2003, a function, scientists believe, of a change in wind patterns that replaced cold Arctic air in the summer with warm southern air. The current rate of global ice melt will raise the seas by 2 feet over the next 80 years, according to a report earlier this year.
What will all this mean for man and the planet on which he resides? Without a massive global effort to change how we create energy, we can expect worse droughts. Stronger storms. More flooding. In short, extreme weather will become even more extreme, with dramatic potential impacts on the inhabitability of large sections of the world. Low-lying ocean islands will be covered by the sea. Coastal zones worldwide will be forced into retreat. Species will disappear, food chains will become disrupted, wars over water and space and human migration will break out. The more scientists delve into the warming phenomenon, the more they learn — and the more they are surprised by — how fast it’s happening and how much worse the repercussions will be if we go on as we have been.
Under the Paris climate pact, world leaders committed to limiting the rise in global temperature to 2 degrees above the pre-industrial era, but with an aspiration to limit it to 1.5 degrees.
Even the Trump administration, which wants to burn fossil fuels with an arsonist’s glee, has acknowledged the impacts of climate change in official reports, though it defies and occasionally denies the science of climate change in formal policies and statements. Remember, President Trump wants to withdraw the U.S. from the Paris agreement, which would make us the only —
Humanity is spinning pell-mell toward self-inflicted disaster, and the largest economy in the world — the country with the second highest industrial output — has official policies to ignore it. Indeed, the U.S. plans to add to the problem for the sake of short-term energy sector gains. Whether Trump’s policies are bred of ignorance or cynicism, they push the nation, and the planet, into ever-more dangerous territory.
