Study projects substantial declines in large fish and marine species with warming oceans – “There are substantial consequences for marine ecosystems on a global scale”

By Alison Auld 11 June 2019 (Dal News) – Populations of large fish and other marine species will decline steadily if little is done to stem the effects of climate change, according to a study led by Dalhousie University researchers that shows how greenhouse gas emissions could cause widespread global stock losses and habitat shifts. […]

White House tried to stop climate science testimony, documents show – “I have never heard of basic facts being deleted from or blocked from testimony”

By Lisa Friedman 8 June 2019 WASHINGTON (The New York Times) – The White House tried to stop a State Department senior intelligence analyst from discussing climate science in congressional testimony this week, internal emails and documents show. The State Department’s Bureau of Intelligence and Research declined to make changes to the proposed testimony and […]

Video: New York is building a wall to hold back the ocean

10 June 2019 (Vox) – Climate change is leading to increasingly violent storms. Can seawalls hold back floods? Staten Island recently received funding for a nearly 5-mile-long seawall to protect its coast. But the plan raises a lot of questions. We’re living in a dangerously dynamic world: Hurricanes are getting worse, wildfires are rampant in […]

BP Statistical Review of World Energy 2019: “A growing mismatch between hopes and reality”

By Spencer Dale 11 June 2019 (BP) – The Statistical Review of World Energy has been providing timely and objective energy data for the past 68 years. In addition to the raw data, the Statistical Review also provides a record of key energy developments and events through time. My guess is that when our successors […]

Hundreds of barges stalled as record floods hinder Midwest supplies – “Very long duration flooding on the Mississippi River can really start to wear on people”

By Brian K Sullivan , Shruti Singh, and Mario Parker 8 June 2019 (Bloomberg) – Hundreds of barges are stalled on the Mississippi River, clogging the main circulatory system for a farm-belt economy battered by a relentless, record-setting string of snow, rainstorms and flooding. Railways and highways have been closed as well, keeping needed supplies […]

Simultaneous heatwaves caused by anthropogenic climate change – “If in future more and more key agricultural regions and densely populated areas are affected by simultaneous heatwaves, this would have severe consequences”

By Peter Rüegg 9 April 2019 (ETH) – Without the climate change caused by human activity, simultaneous heatwaves would not have hit such a large area as they did last summer. This is the conclusion of researchers at ETH Zurich based on observational and model data. Many people will remember last summer – not only […]

Ninth Circuit judges appear skeptical of role in kids’ climate suit vs. U.S. government – “It may even rise to the level of criminal neglect. But the tough question for me is do we get to act because of that.”

By Karen Savage 4 June 2019 (Climate Liability News) – A three-judge panel of the Ninth Circuit Court of Appeals on Tuesday appeared skeptical of the court’s role in dealing with climate change in the landmark constitutional climate case brought by 21 young people against the U.S. government. But the kids’ attorneys argued in a […]

Graph of the Day: Carbon emissions and human population, 1751-2018

9 June 2019 (Desdemona Despair) – It’s time to update one of Desdemona’s favorite graphs: human carbon emissions per capita. In the last update, four years ago, we had carbon emissions data through the year 2013, and it was clear that per-person emissions growth followed a nearly perfect exponential curve. The curve passed through one ton […]

As oceans warm, microbes could pump more carbon dioxide back into the air

By Kevin Krajick 29 April 2019 (Columbia University) – The world’s oceans soak up about a quarter of the carbon dioxide that humans pump into the air each year — a powerful brake on the greenhouse effect. In addition to purely physical and chemical processes, a large part of this is taken up by photosynthetic plankton as they incorporate carbon into their […]

U.S. schools censoring climate crisis message in graduation speeches – “We are tearing down our home, the Earth, and it should be our Number 1 concern in the world. But it’s not.”

By Oliver Milman 7 June 2019 (The Guardian) – Schools and colleges across the US have been accused of censoring students who have attempted to use their graduation speeches to speak out on the unfolding climate crisis. A youth-led movement called Class of 0000 is encouraging students to read out a prepared text at their graduation ceremonies […]
