Acceleration of Climate Change

Human activity is changing Earth’s climate 170 times faster than natural forces, according to scientists who claim they have devised an equation that shows people are behind global warming.

According to researchers, global temperatures decreased by 0.01C per century over the last 7,000 years—the “baseline” rate. But in the last 45 years it has increased by the equivalent of 1.7C per century, and the 12 warmest years on record have come since 1998, they said.

While “astronomical and geophysical” as well as biospheric forces have driven change in the “Earth system” over its four billion-year existence, human activity has “driven exceptionally rapid rates of change” that the authors of a new study have represented in an “Anthropocene equation”.

Anthropocene is the name given to a proposed new geological era in which the impact of human activity starts having a measurable impact on the environment.

Writing in New Scientist, the study’s co-author Owen Gaffney said: “The rate of carbon emissions to the atmosphere is arguably the highest in 66 million years, when the (non-avian) dinosaurs slipped off this mortal coil.

“The staggering loss of biodiversity in recent decades prompted researchers in 2015 to argue that the Anthropocene marks the third stage in the evolution of Earth’s biosphere, following on from the microbial stage 3.5 billion years ago and the Cambrian explosion 650 million years ago.

“In the equation, astronomical and geophysical forces tend to zero because of their slow nature or rarity, as do internal dynamics, for now. All these forces still exert pressure, but currently on orders of magnitude less than human impact.”

The risks of human impact on the biosphere includes polluted water and soils as well as a warmer climate, Mr Gaffney said.

He added: “While it would seem imprudent to ignore the huge body of evidence pointing to profound risks, it comes at a challenging time geopolitically, when both fact-based world views and even international cooperation are questioned. Nowhere has this been clearer than in the US in recent weeks.”

Taking Space

The HabitatMap & AirCasting Blog have come together for a space to collectively crowdsource live streaming air-quality data. Last November, New York city has even been leveraging AirBeam Data to Inform Policy Decisions!
New York City recently committed to implementing a “zoned” collection system for the commercial waste sector. By dividing the city into zones and having commercial carting companies bid to service each zone, the city’s study found that the number of miles traveled by private collection vehicles will be cut by an astounding 49 to 68 percent!  This is a win for both the private carting companies, which will be able to achieve dramatic efficiencies in operations, and everyday New Yorkers, who will have to contend with less noise and air pollution.

If we are able to optimize the trash zoning over in more mega-cities, this could make a big impact on pollution  worldwide.

AirCasting

AirCasting is an open-source, end-to-end solution for collecting, displaying, and sharing health and environmental data using your smartphone. The platform consists of wearable sensors that detect changes in your environment and physiology, including a palm-sized air quality monitor called the AirBeam, the AirCasting Android app, the AirCasting website, and wearable LED accessories. By documenting and leveraging health and environmental data to inform personal decision-making and public policy, the AirCasting platform empowers citizen scientists and changemakers.
