Nearly 14,000 scientists have signed a new climate emergency document, warning that “immeasurable suffering” awaits humanity if we do not start working on it. global warming From the front, it will be effective immediately.
A new treatise published in the journal on July 28 Bioscience Led by researchers at Oregon State University, 2019 treatise It declared a global “climate emergency” and evaluated the vital signs of the Earth based on 31 variables. Greenhouse gas Emissions, changes in surface temperature, glacier ice block loss, Amazon rainforest loss, as well as various social factors such as global gross domestic product (GDP) and fossil fuel subsidies.
Not surprisingly, the author of a new treatise finds it EarthVital signs have only deteriorated in the last two years, with 18 of the 31 categories in the report recording record highs or lows, the authors write. According to the report, greenhouse gas emissions are the highest ever and glacier ice thickness is the lowest in 71 years of record keeping. The world is richer than ever (measured by global GDP) and the sky is more polluted than ever (measured by global GDP) carbon dioxide, Atmospheric methane and nitrous oxide concentrations).
“The updated planetary vital signs we present reflect, as always, the results of relentless business,” the author writes in a study. “The main lesson from COVID-19 is that even a significant reduction in transportation and consumption is not enough, instead a change in the transformation system is needed and they have to go beyond politics.”
The report includes some positive trends, such as record increases in solar and wind energy use and institutions selling funds from the fossil fuel industry, but floods, Hurricane, Forest fire When heat wave, The author wrote. The planet may also be about to (or have already) passed an important natural turning point. Amazon rainforest becomes a carbon source The team added that it was not a carbon sink and was difficult to recover.
This is all summarized in one conclusion: the future habitability of our planet depends on immediate, large-scale action, the author writes.
To accomplish this task, the team proposes a three-sided short-term policy approach. 1) Implement “significant” global carbon prices to reduce emissions. 2) Gradually abolish and finally ban fossil fuels. 3) Restore and protect major carbon-rich ecosystems such as forests and wetlands to protect the planet’s largest carbon sinks and protect biodiversity.
“Immediate implementation of these three policies will help ensure the long-term sustainability of human civilization and give future generations the opportunity to prosper,” the author writes. “The speed of change is essential and the new climate policy should be part of the COVID-19 recovery plan.”
Researchers will release a “check-in” for another planet in the coming years. Hopefully, as more countries take the seriousness of climate change seriously, their future reports will show more signs of positive change.Or maybe it will be reflected Social collapse.. Time — and political action — will tell you.
