Unrelenting Warming: The World Economic Forum’s Global Risks Report for 2019 indicates environmental problems are most serious threat to global stability
Mel Gurtov, Peace Voice
The World Economic Forum’s Global Risks Report for 2019 indicates that most experts point to environmental problems as being the most serious threats to global stability—just as they found in the previous two years. That report follows on one in October 2018 by the UN Intergovernmental Panel on Climate Change (IPCC).
It said with “high confidence” that at the current rate of greenhouse gas emissions, “global warming is likely to reach 1.5°C between 2030 and 2052 if it continues to increase at the current rate.”
Avoiding the worst-case consequences would require measures that have “no documented historic precedent.”
As Americans see the evidence of climate-influenced destruction, they’re on edge: Seventy-two percent of those polled late last year considered climate change “important,” a 15-percentage point increase over 2015. Sixty-nine percent were “worried” about it.
So here we are again, facing another round of bad news on the environment. Actually, the news is worse this time around. 2018 was the fourth-hottest year on record; 2015-2017 are the other three. The Arctic experienced its second-warmest year ever. The head of the World Meteorological Organization said: “The 20 warmest years on record have been in the past 22 years. The degree of warming during the past four years has been exceptional, both on land and in the ocean.”
Rising sea levels, according to the IPCC, “will continue beyond 2100 even if global warming is limited to 1.5°C in the 21st century (high confidence). Marine ice sheet instability in Antarctica and/or irreversible loss of the Greenland ice sheet could result in multi-metre rise in sea level over hundreds to thousands of years.”
Greenland’s and Antarctica’s ice loss has recently received extensive media coverage as scientists have discovered just how far off their earlier predictions were. Antarctica’s enormous ice reserves are melting six times faster now than they were between 1979 and 1989. Glacier melting in the Himalayas, on which South Asian agriculture is heavily dependent, is proceeding at a very fast pace—so much so that by the end of this century, two-thirds of the glaciers may be gone at current climate change rates, and one-third under the most optimistic climate change scenarios.
Ocean temperatures are the warmest on record, and the warming is occurring at a terrifying pace: 40 to 50 percent faster than the United Nations had previously estimated. That could spell trouble for marine ecosystems, phytoplankton in particular. These basic food organisms sustain the underwater food chain. If they die off or shift, as is already detectable in changing ocean color, the impact on fisheries will be catastrophic.
Rising seas also threaten water supplies and US island-based military installations. No wonder the Pentagon, in its latest risk assessment, considers climate change a threat to national security. It can wipe countries off the map. Kiribati, the island group in the southwest Pacific, is a case in point. A nation disappearing due to climate change is something that’s never happened before and, so far, is something people seem unable to imagine.
Time for Mega-solutions
Several conclusions are readily apparent from this information.
- First, planet-wide environmental deterioration is happening faster—much faster—than scientists had anticipated.
- Second, the kind of deterioration now taking place, involving oceans and glaciers in particular, tell us that life itself is already endangered in many parts of the globe.
- Third, some consequences of climate change, such as rising seas, are irreversible.
- Fourth, resistance to scientific findings and their implications for political, economic, and social changes constitutes nothing short of criminal negligence.
- Fifth, people are more aware of and concerned about climate change than ever before, if the US poll mentioned above is accurate.
- Sixth, solutions to the problem must be up to the scale of the problem.
Tiny, personal steps to reduce carbon footprints feel good, but it’s panic time, folks.
In the US, the renowned environmentalist Bill McKibben suggests two priority steps: switching immediately away from fossil fuels and protecting cities and coastal areas from ocean inundation. Strict efficiency standards for industry and autos, and a carbon tax such as has been enacted in Europe, would significantly reduce carbon emissions.
Then there’s the Green New Deal resolution introduced in the US Congress by Rep. Alexandria Ocasio-Cortez and Sen. Ed Markey. The resolution calls for a “ten-year national mobilization” to bring carbon emissions down to zero via a combination of renewable energy, infrastructure repairs, and community-level projects.
The next Democratic president should declare a national emergency, identifying climate change as a top-priority national security matter and presenting the Congress with an agenda for climate-change legislation.
As the IPCC report makes clear, mitigating climate change requires across-the-board and multilevel changes, from sustained international cooperation, including funding the most affected developing countries, to addressing poverty and health care deficits.
Political leaders, who always have excuses for ignoring problems that will outlive them, can point to other issues that require their immediate attention. Even the most liberal among them hesitate to embrace the up-front financial costs and social challenges of a serious climate change agenda, though they know full well that the benefits of a green economy—in jobs, energy, reduced waste, and public health, for instance—will outweigh the costs.
That leaves the fight up to this generation of ordinary citizens. How inspiring to learn that all across Europe, tens of thousands of young people are demanding action to save the planet.
They are organizing a “global strike” on March 15. But if their elders won’t act, or even acknowledge the urgency of global warming, it is hard to imagine that all the wonderful grassroots environmental and energy initiatives underway around the world will be enough to save us and future generations.
