Thousands Of Scientists Around The World Declared A Climate Emergency And Warned Of "Untold Suffering"
The climate crisis "is more severe than anticipated, threatening natural ecosystems and the fate of humanity," thousands of scientists said in a dire warning.
More than 11,000 scientists from around the world issued a dire warning Tuesday that the world must take immediate action to fundamentally alter a range of human activities to avert "untold suffering due to the climate crisis."
In a statement published in the journal BioScience, the scientists declared that the Earth is facing a "climate emergency" and that, despite continued warnings about "insufficient progress" over the last several decades, greenhouse gas emissions are continuing to increase and posing "increasingly damaging effects on the Earth's climate."
They wrote: "An immense increase of scale in endeavors to conserve our biosphere is needed to avoid untold suffering due to the climate crisis."
The group, which includes experts from 153 countries, cited increases in human and livestock populations, meat production, world gross domestic product, tree cover loss, air travel, fossil fuel consumption, and carbon dioxide emissions as factors that have contributed to the crisis.
The scientists said they were encouraged by decreases in global fertility rates, decelerated forest loss in the Amazon rainforest, and increases in the use of solar and wind power. However, they also noted the decline in fertility rates has slowed in recent years and the rate of deforestation in the Amazon has started to increase again. And, despite increases in consumption of cleaner sources of energy, consumption of solar and wind energy was still 28 times smaller than that of fossil fuels last year.
The new warning comes just a day after President Donald Trump officially notified the UN that he would withdraw the United States from the 2015 Paris climate agreement.
"Despite 40 years of global climate negotiations, with few exceptions, we have generally conducted business as usual and have largely failed to address this predicament," the scientists said, adding that the climate crisis has accelerated faster than most had previously predicted. "It is more severe than anticipated, threatening natural ecosystems and the fate of humanity."
In two reports released earlier this year, the UN's Intergovernmental Panel on Climate Change described how global warming is already altering Earth's climate and ecosystems from magnifying heat waves and droughts to supercharging tropical cyclones.
According to the September report on seas and ice systems, ocean warming will lead to more frequent tropical cyclones and increase flooding risks for low-lying coastal cities and island communities so much so that some small islands could become uninhabitable.
In Tuesday's statement, the scientists called on governments, businesses, and people to take a series of six actions to lessen the effects of climate change:
- Replace fossil fuels with cleaner sources of energy and pursue negative emissions through carbon extraction and capture technologies.
- Reduce emissions of pollutants like methane, soot, and hydrofluorocarbons.
- Protect and restore Earth's coral reefs, forests, savannas, wetlands, and other ecosystems that help store carbon.
- Reduce consumption of meat and other animal products in favor of more plant-based foods.
- Shift economic goals from GDP growth toward sustainability and prioritize reducing inequality.
- Lower fertility rates to lessen the impacts of population growth on emissions.
"Mitigating and adapting to climate change while honoring the diversity of humans entails major transformations in the ways our global society functions and interacts with natural ecosystems," the scientists said. "We believe that the prospects will be greatest if decision-makers and all of humanity promptly respond to this warning and declaration of a climate emergency and act to sustain life on planet Earth, our only home."
