9 Steps Cities Must Take to Dramatically Cut Carbon Emissions

9 Steps Cities Must Take to Dramatically Cut Carbon Emissions | Ordenación del Territorio | Scoop.it

A very long, very bold to-do list for the next 20 years.

The city of Toronto has already begun to sketch out policies that could reduce the area’s greenhouse gas emissions in the coming decades. Officials have proposed greening the electric grid, banning incandescent light bulbs, promoting green roofs on commercial buildings, retrofitting 1960s-era high-rises and implementing a stricter energy-efficient building code for new construction. With transportation, the city wants to expand bike lanes and transit infrastructure, all while it anticipates that electric vehicles will grow slowly more common.

This is a pretty standard menu of ideas, and according to scientists it will get the city part of the way toward the kind of changes broadly needed to really keep global temperature rise below 2 degrees Celsius.

But to really alter the future prospects for climate change, much more will have to happen in Toronto, and every other city. Researchers used the city as a case study to model what a truly aggressive framework might look like. If Toronto wants to cut emissions by 70 percent by 2031, all of these actions (or others with a similar impact) might be required in tandem...

While the steps being proposed in Toronto may not be as aggressive as those recommending by researchers concerned with reversing the climate changes caused by humanity's activity, they are at least a step in the right direction and far more than what seems likely in most U.S. cities.

Watch 62 Years of Global Warming in 13 Seconds

Watch 62 Years of Global Warming in 13 Seconds | Ordenación del Territorio | Scoop.it

An amazing 13-second NASA animation depicting how the globe has warmed during the period of 1950 to 2012.


From our friends at NASA comes this amazing 13-second animation that depicts how temperatures around the globe have warmed since 1950. You’ll note an acceleration of the temperature trend in the late 1970s as greenhouse gas emissions from energy production increased worldwide and clean air laws reduced emissions of pollutants that had a cooling effect on the climate, and thus were masking some of the global warming signal.

 

The data come from NASA's Goddard Institute for Space Studies in New York (GISS), which monitors global surface temperatures. As NASA notes, “All 10 of the warmest years in the GISS analysis have occurred since 1998, continuing a trend of temperatures well above the mid-20th century average.

Why we should care about global warming. And keep working on solutions (they exist).
