Painting wind turbines black could help protect birds – as long as it doesn’t disrupt their migration

While wind farms aren’t quite the bird slayers they’re often portrayed to be – one study found that they cause 0.4 deaths per gigawatt hour (GWh) of electricity generated, compared with 5.2 dead birds for every GWh generated by fossil-fuelled power stations – wildlife collisions with turbines and power lines are likely to be an […]

Hydroponics part 1: Growing the food we need without dirt

Hydroponics is a type of aquaculture that uses nutrients and water to grow plants without soil. It is an increasingly popular growing method in urban areas and regions with extreme climates. There are many benefits to hydroponics as an alternative form of agriculture, including fewer chemicals, higher yields and greater water efficiency. By Emily Folk […]

Explainer: What is a tipping point, and why should I care?

Lately, you may have heard someone say that we have reached a “tipping point.” This year alone, with the economic downturn caused by the Covid-19 pandemic and the sustained civil unrest sparked by the killing of George Floyd by a Minneapolis police officer, we have witnessed dramatic shifts in our social and economic states of […]

Sexual harrassment of women in STEM needs to STOP. It’s bad for people, it’s bad for science, it’s bad for business.

In 2018, the National Academies published a consensus report on Sexual Harassment of Women in Science, Engineering and Medicine that explored the fact that while “there are significantly more women entering careers and studying science, engineering, and medicine than ever before,” those women “face biases and barriers and it is not surprising that sexual harassment […]

Extreme glacier loss events officially linked to human-caused climate change for first time

  The rapidly evolving scientific field of “extreme event event attribution” has detected the fingerprint of human-caused climate change on a wide range of extreme weather events, including heatwaves, floods, wildfires and drought. Now, for the first time, scientists have quantified the influence of climate change on specific episodes of extreme ice loss from glaciers. […]

Columbia University’s new model for pricing carbon will help meet net-zero climate change goals

An article released today by researchers at Columbia University’s Center on Global Energy Policy in the journal Nature Climate Change introduces a new approach for pricing carbon — Near-term to Net Zero. As policymakers and advocates increasingly focus on net-zero emissions by midcentury, the Near-term to Net Zero approach is a method of setting carbon prices that could […]

Dr. James Hansen: Why are you optimistic?

Why are you optimistic, I have often been asked since I wrote Young People’s Burden, which describes the steep climate and energy hill that we are leaving for young people to climb. Two weeks ago I noted the Students Government Leaders’ Statement on Carbon Dividends, a bipartisan statement by 350+college student government presidents from all 50 states.  Scroll down […]

New guide to diversity In STEM deals with racism in academia and science

Back in 2017, we discussed why racism matters for science, in 2018 we explored the intersectionality of hate and climate denial, and in January of 2019, pointed you to now-rather-busy Professor Ibram X. Kendi’s anti-racism research. Since then, we’ve explained how racism is driving air pollution, highlighted the NAACP’s report on fossil fuel propaganda, spotlighted Nazis in conservative media and white nationalists in Oregon, reminded the environmental community of its own failings, […]
