Warming ocean will drive many commercially important species to new habitats; detailed projections can help coastal communities adapt
Climate change isn’t just heating the surface of the Earth. It’s also warming deep ocean water, and along the coast of the northeastern U.S. bottom-water temperatures are expected to increase by 6.6 to 9 degrees Celsius by 2100.
That means that commercially important marine species will also continue to shift northward, which is important information for fishermen trying to make living in the region. Just how much and when they will move is the subject of new research published this week in the journal Progress in Oceanography.Continue reading “Global warming means major changes for U.S. fisheries”→
EcoDiesel engines on Ram trucks and Jeep Cherokees at issue in civil suit
The EPA may not be beating the climate change drum any more, but it apparently still wants to hold automakers accountable for emissions scams. This week, the agency announced it’s filing a civil complaint against Fiat Chrysler Automobiles, alleging that the company installed cheat software on almost 104,000 light duty diesel vehicles.
According to the EPA, the 3.0 liter EcoDiesel engines are equipped with software functions that were not disclosed to regulators during the certification application process, and that the vehicles contain defeat devices. The complaint alleges that the undisclosed software functions cause the vehicles’ emission control systems to perform less effectively during highway driving than on federal emission tests, resulting in increased emissions of harmful air pollutants.

The world committed to taking action on climate change in Paris, and now, all the countries that signed on to the agreement to cut greenhouse gas emissions and limit global warming to less than 2 degrees Celsius are figuring exactly how that will happen, and how they will hold each other accountable.
U.S. climate policy is in question now, and the political changes definitely featured in the Bonn discussions, but didn’t dominate the proceedings. Some of the international climate negotiators recognized that the world is a dynamic place and that some national policies will come and go. But that won’t stop the world from moving ahead with ambitious climate plans. other experts discussed how the U.S. could hamper the global effort, while others said the U.S. should remain in the agreement, but not at any cost. For the sake of the rest of the world, the agreement should not be weakened. Read more in this report from Bonn.
Some of the most hopeful news from Bonn was that China and India are quickly shifting to a renewable energy economy. That will not only help those countries reduce their significant emissions, but will also drive a global shift by reducing the price for renewable energy to the point where it will quickly become the cheapest option. Even the U.S. reported a drop in greenhouse gas emissions the past few years, primarily because of the switch from coal to natural gas. American envoy Trigg Talley faced polite but insistent and pointed questioning during a disclosure session. Read the details in this story.
It all matters because for the less-developed countries in the global south, climate change is an existential question. There was concern about the Trump administration’s climate stance, but also optimism. Nobody wanted to make a final judgment on U.S. policy, which seems to still be in question, but nevertheless, some of the negotiators from the world’s most vulnerable countries seemed to be responding to Trump’s statements on the Paris climate agreement and on climate policies in general:
“Without increased climate action, no country can ever be great again. We fought hard for the Paris Agreement and the 1.5-degree threshold, the threshold for our survival…. Greatness is most apparent with climate action. Failure is not an option.”
Iceland is the kind of place where you could lose myself for a lifetime between the sea, sky and mountains, not to mention the soft, high-latitude light that sparks nature’s inner light, lending a glow to every scene. A few more galleries here.
Ruling that the U.S. Forest Service violated federal law when it made an arbitrary and capricious decision to approve a land exchange near Wolf Creek Ski Area, U.S. District Court Judge Richard Matsch set aside the agency’s 2015 approval for a land trade that would have enabled large-scale resort development., The decisions says the Forest Service failed to look closely at the environmental impacts of its decision, and failed to listen to the public before making its decision.

Proposed bill would enable desert-killing groundwater exploitation
After failing several times to win approval for a new groundwater depletion scheme via regulatory channels, the Southern Nevada Water Authority is now pursuing a legislative water grab that could devastate fragile desert ecosystems and push some endangered species even closer to extinction.
Most recently, the Nevada Supreme Court rejected the Las Vegas bid for a new pipeline.
Assembly Bill 298 would enable for groundwater export projects that would harm prings and wetlands, degrade air quality with fugitive dust and impact existing water rights holders. During the hearing numerous members of conservation groups and the public spoke to vigorously oppose the bill. Continue reading “Thirsty Las Vegas pushes legislative water grab”→
Basic physics tells us a warmer atmosphere can hold more moisture, and that, at some point, that moisture will condense and fall as rain. That’s why climate scientists are certain that global warming will lead to more extreme rainfall, as has already been documented in various parts of the world the past few decades.
A new study now helps quantify the impact of warming and also reveals regional patterns that will help people prepare. According to the researchers with MIT and the Swiss Federal Institute of Technology, the most extreme rain events in most regions of the world will increase in intensity by 3 to 15 percent, depending on region, for every degree Celsius that the planet warms.
