The U.S. National Library of Medicine’s TOXNET, an interactive map that tracked pollution, chemical exposure, toxicology and other data, was shut down last month. The move has been criticized in the context of the Trump administration’s rollback of environmental protections, but the NLM insists that the decision was theirs. The data mapped by TOXNET is available from other sources, but, and this is the point, not as easily or centrally accessible. [The Hill, Newsweek]
Google is using its Street View cars, now equipped with air-quality sensors, to measure air pollution in California on a block-by-block level.
Earlier this year, we shared the first results of this effort with pollution levels throughout the city of Oakland.
We’re just beginning to understand what’s possible with this hyper-local information and today, we’re starting to share some of our findings for the three California regions we’ve mapped: the San Francisco Bay Area, Los Angeles, and California’s Central Valley (the Street View cars drove 100,000 miles, over the course of 4,000 hours to collect this data!) Scientists and air quality specialists can use this information to assist local organizations, governments, and regulators in identifying opportunities to achieve greater air quality improvements and solutions.
President Trump’s budget proposes eliminating the EPA’s Great Lakes Restoration Initiative. That fact is no doubt what’s behind two publications posting maps earlier this month, only a couple of days apart, showing the environmental stresses on the Great Lakes basin.
Canadian Geographic reposted a map from their July/August 2013 issue:
And the Washington Post included the following map in an article on the proposed elimination of two EPA programs (including the aforementioned Great Lakes Restoration Initiative):
By cross-referencing public data on energy consumption with georeferenced tax lot data, Jill Hubley has created an interactive map of New York City’s greenhouse gas emissions by property, colour-coded to show the biggest emitters. More on how she did it, and what the data reveal. [via]
