President Barack Obama didn’t need to be convinced that climate change is an increasingly serious 21st century problem for the Earth and all life on the planet.
But it is good that he went to Alaska and visited Exit Glacier to point out the undeniable global warming problem to the U.S. and the rest of the world. The 2-mile long solid ice has been retreating more rapidly than before.
The damage is evident in polar regions throughout the world. In Obama’s visit, markers along his hike had noted where the glacier once stood. But now only dry land remains. Exit Glacier has receded at an alarming rate of 43 feet a year, the National Park Service reports.
The president hopes to convey a sense of urgency about climate change and the need for the country to take action to reduce human consumption of fossil fuels to decrease the planet’s greenhouse gas problem.
