Originally published on Legal Planet. To do its part in keeping climate change to tolerable levels, the United States needs to cut its carbon emissions at least 80 percent below 1990 levels by 2050. That’s not just a matter of decarbonizing the electricity sector; it means changes in everything from aviation to steel manufacture, and reducing not […]

Pop quiz: What do marshes, pipelines, forests, and underground parking structures have in common? The answer is they are all infrastructure – part of the "underlying foundation," as my dictionary puts it, "on which the continuance and growth of a community depend." A lot of that foundation, like pipelines and parking structures, is artificial. But […]

In 1956, Texas oil geologist M. King Hubbert predicted that U.S. oil production would peak no later than 1970. Lo and behold, in 1970, oil production topped out at just over 9.6 million barrels a day (mbd) and began its decline. The predicted peak had been reached. Regarding the world oil supply – no worries. […]

Fossil fuels are reaching their consumption peak. By way of example, the United States has a surfeit of coal, but coal use is on the decline as natural gas and renewable resources replace the dirty fuel for generating electricity. Similarly, oil and natural gas are on the same decreasing consumption trajectory as recent data and […]

Originally published by The Conversation. The Trump administration's push to boost fossil fuel extraction has received a major setback. On March 29, Judge Sharon Gleason of the U.S. District Court for Alaska ruled invalid Trump's order lifting a ban on oil and gas drilling in much of the the Arctic Ocean and along parts of […]

The Chesapeake Bay Program has just compiled its annual data assessing progress toward the watershed-wide pollution reduction target under the Bay restoration framework known as the "Bay TMDL." The bottom line is that recent gains in Bay health could soon be eclipsed by the lagging pace of pollution reductions, with the likely result that the region will fall well short of the Bay TMDL 2025 target date to achieve the reductions needed to restore the Bay's health.
