The World Passes 400 PPM Threshold. Permanently

The World Passes 400 PPM Threshold. Permanently | Développement durable et efficacité énergétique | Scoop.it

Carbon dioxide just hit its annual minimum and failed to dip below 400 ppm. We're unlikely to see a month below that level in our lifetimes.

In the centuries to come, history books will likely look back on September 2016 as a major milestone for the world’s climate. At a time when atmospheric carbon dioxide is usually at its minimum, the monthly value failed to drop below 400 parts per million.

That all but ensures that 2016 will be the year that carbon dioxide officially passed the symbolic 400 ppm mark, never to return below it in our lifetimes, according to scientists.

Stephane Bilodeau's insight:
"Even though there are some hopeful signs that world leaders will take actions to reduce emissions, those actions will have to happen on an accelerating timetable in order to avoid 2°C (3.6°F) of warming. That’s the level outlined by policymakers as a safe threshold for climate change. And even if the world limits warming to that benchmark, it will still likely spell doom for low-lying small island states and have serious repercussions around the world, from more extreme heat waves to droughts, coastal flooding and the extinction of many coral reefs. 

It’s against this backdrop that the measurements on top of Mauna Loa take on added importance. They’re a reminder that with each passing day, we’re moving further from the climate humans have known and thrived in and closer to a more unstable future."

It can't be denied any longer: Sea levels are rising, major droughts are continuing, and record hot summers are being experienced al around the world.

A recent study conducted by Yale University and George Mason University finds that for the first time since the research began in 2008, the majority of Americans believe that global warming is mostly a man-made phenomenon. And as sobering images of catastrophes make headlines, people are recognizing that the effects of their actions are not just an increasing danger to the world but a direct threat to themselves and their families.

Visualizing How New York City Heats Up In The Summertime

Visualizing How New York City Heats Up In The Summertime | Développement durable et efficacité énergétique | Scoop.it

If you find the summer heat hard to take, cities are the worst places to be. Studies show that urban spaces can be up to three degrees hotter than surrounding areas. That's because of the "heat island effect"--which is what you get from paving every available surface with heat-absorbing asphalt and concrete.

 

Using a thermal camera, these graphics by artist-researcher Nickolay Lamm explain how a city gets hot and stays hot.
