Areas of the planet home to one-third of humans will become as hot as the hottest parts of the Sahara within 50 years, unless greenhouse gas emissions fall, according to research by scientists from China, USA and Europe published in the journal Proceedings of the National Academy of Sciences this week. The rapid heating would mean that 3.5 billion people would live outside the climate ‘niche’ in which humans have thrived for 6,000 years.
It's not like people hadn't looked into this issue decades ago and tried to warn us or anything. Now it's probably too late to prevent the worst kinds of natural disasters from occurring but hey at least we got to buy and waste a lot of unnecessary stuff whilst expoiting the planet's resources at a record pace just so a few guys could make a lot of money. What future generations?
As the 21st century progresses, rising atmospheric carbon dioxide (CO2) concentrations will cause urban and indoor levels of the gas to increase, and that may significantly reduce our basic decision-making ability and complex strategic thinking, according to a new CU Boulder-led study. By the end of the century, people could be exposed to indoor CO2 levels up to 1400 parts per million -- more than three times today's outdoor levels, and well beyond what humans have ever experienced.
However, according to an international study led by the University of Leeds, unless large-scale, structural interventions — like a significant switch away from fossil fuels — are implemented, these changes will not affect Earth's climate. In fact, the researchers found, even if lockdown measures continue in some fashion around the world until the end of 2021, more than a year and half total, global temperatures will only be roughly 0.018 degrees Fahrenheit (0.01 degrees Celsius) lower than expected by 2030.
Temperatures in the Arctic Ocean between Canada, Russia and Europe are warming faster than researchers' climate models have been able to predict.
Over the past 40 years, temperatures have risen by one degree every decade, and even more so over the Barents Sea and around Norway's Svalbard archipelago, where they have increased by 1.5 degrees per decade throughout the period.

Warming soils in the tropics could cause microbes to release carbon dioxide from storage. One scientist called the finding “another example of why we need to worry more.”
The Trump administration is revoking rules that require oil and gas drillers to detect and fix leaks of methane, a greenhouse gas that heats the planet far faster than carbon dioxide.
