The United Nations Climate panel released its report Sept. 25, with lead author French climate scientist Valerie Masson-Delmotte warning "Climate change is already irreversible. Due to the heat uptake in the ocean, we can't go back.” She shared that seas are rising 2.5 times faster than the rate from 1900 to 1990; that from 2006 to 2015, the ice melting from Greenland, Antarctica and the world's mountain glaciers has accelerated and they are now losing 720 billion tons of ice a year; that marine animals are likely to decrease 15%, and catches by fisheries in general are expected to decline 21% to 24% by the end of the century because of climate change.
Villanova’s Stephen M. Strader, Ph.D., a hazards geographer and atmospheric scientist, says because the earth is warming faster than previously thought we have to act now to curb global greenhouse gas emissions. “Unfortunately, there is a momentum to the climate system. Even if we 100% curb global greenhouse gas emissions immediately, we have committed to substantial global warming.”
Strader adds that an interesting note in the UN report is the indication that climate action is inseparable from sustainable development. The report mentions an important aspect of climate change effects, such as the issue of disproportionate impact on the poor and most vulnerable regions of the world. “Building more sustainable communities will not only reduce inequality and vulnerability”, he says, “it will also help fight global climate change. They are hand in hand.”
Climate change is an existential crisis to human beings everywhere, regardless of where you live,” says Strader. “It is affecting and will continue to have consequences related to shelter, food, water, etc., the basic necessities to sustain life. The lack of inaction by politicians, policy makers, and the general public is alarming given the threat all of humanity is facing. The threat is not just 10 or 50 years from now, but today.”
