According to a report released on Monday by the United Nations, the Earth's climate is becoming so heated that temperatures will likely blow over a level of warming that world leaders have wanted to avoid in about a decade.
Linda Mearns of the National Center for Atmospheric Research, one of the report's co-authors, believes that no place would be immune to climate change. Nonetheless, experts have backed off on the likelihood of the worst climatic disasters.
"This report is a wake-up call," stated Valérie Masson-Delmotte, co-chair of IPCC Working Group I. "Advanced technologies can help us to know the past, present, and future climatic conditions, which is crucial for determining where we're heading, what we can do, and how we can prepare," says the author.
Climate change is certainly human-caused and "unequivocal," according to the authoritative Intergovernmental Panel on Climate Change (IPCC) report, which offers more specific and warmer estimates for the twenty-first century than it did the previous time it was produced in 2013.
Extreme weather occurrences, such as strong heat waves and "flooding from significant precipitation events," will continue to be exacerbated, according to the paper. "Frequent and severe coastal flooding in low-lying areas, as well as coastal erosion," will continue to be a problem for coastal cities.
While certain changes are already irreversible, the research suggests that governments can take steps to prevent tragedy shortly.
In a news release, the IPCC stated, "The evidence is unequivocal that carbon dioxide (CO2) is the dominant driver of climate change, even if other greenhouse gases and air pollution also affect the climate."
"Strong, rapid, and persistent reductions in greenhouse gas emissions, as well as net-zero CO2 emissions, will be required to stabilize the climate," Zhao said, adding that limiting other greenhouse gases and air pollution, particularly methane, could have health and climatic benefits.
While calling the findings "a code red for mankind," UN Secretary-General Antonio Guterres expressed some optimism that world leaders may still prevent 1.5 degrees of warming, which he described as "dangerously close “Anything we can do to minimize, to slow down, will pay off,” Tebaldi said.
If we can’t go 1.5 it will be back-breaking, but it's vital not to give up. According to the reports, the planet can be 3.3 degrees hotter, by the end of the century than it is at the present. But, according to report co-author and climate scientist Zeke Hausfather, climate change director of the Breakthrough Institute, that scenario is becoming increasingly unlikely.
We're a lot less likely to strike it rich and experience less warming than we anticipated. “Without rapid near-term carbon reductions, we will not be able to reach the Paris Agreement goals,” Hausfather warned.
Ultra-catastrophic calamities, often known as "tipping points," such as ice sheet collapses and rapid slowing of ocean currents, are "low possibility" but cannot be ruled out, according to the paper. The much-discussed shutdown of Atlantic ocean currents, which would cause huge weather shifts, is unlikely to occur this century, according to Kopp.
