OF THE
TIMES
Now, more than at any time in our history, our species needs to work together. We face awesome environmental challenges: climate change, food production, overpopulation, the decimation of other species, epidemic disease, acidification of the oceans. Together, they are a reminder that we are at the most dangerous moment in the development of humanity. We now have the technology to destroy the planet on which we live, but have not yet developed the ability to escape it.There is not a single point here that is inaccurate or hyperbolic. For example, consider that the hottest 17 years on record have all occurred since 2000, with a single exception (namely, 1998), and with 2016 being the hottest ever. Although 2017 probably won't break last year's record, the UK's Met Office projects that it "will still rank among the hottest years on record." Studies also emphasize that there is a rapidly closing window for meaningful action on climate change. As the authors of one peer-reviewed paper put it:
The next few decades offer a brief window of opportunity to minimize large-scale and potentially catastrophic climate change that will extend longer than the entire history of human civilization thus far. Policy decisions made during this window are likely to result in changes to Earth's climate system measured in millennia rather than human lifespans, with associated socioeconomic and ecological impacts that will exacerbate the risks and damages to society and ecosystems that are projected for the twenty-first century and propagate into the future for many thousands of years.
