Data! 10 charts show the economic benefits of US climate action

The United States made substantial progress towards a low-carbon economy over the past several years. Low-carbon technologies became more efficient and affordable compared to fossil fuels, while U.S. clean energy investment and deployment grew to new heights, creating millions of jobs. All this progress could be in jeopardy due to the economic impacts of COVID-19 and government […]

Science elicits hope in Americans – its positive brand doesn’t need to be partisan

Harley-Davidson is one of the most iconic brands in the world. Harley-Davidson, however, doesn’t sell motorcycles – it sells a lifestyle. Look at any Harley-Davidson advertisement and you will see someone riding the open road. The Harley-Davidson brand is about freedom. Attitude. Living by your own rules. Todd Newman, University of Wisconsin-Madison The Conversation A […]

A brief (and frustrating) history of the carbon footprint

I’ve long fretted about the personal change/system change debate, worried that the weight was unevenly born by individuals even though I strongly believe the former is a necessary catalyst for the latter. But maybe I’m J.K. Rowling-level wrong. Maybe we can skip the skipping straws and go straight to table-flipping the system. At least, that’s how I […]

Dr James Hansen – Every rock has a story (and The Rock Whisperer)

Children should be introduced to our remarkable planet while young, when their curiosity is easily stoked.  If you have young ones ready to sit still for 6-9 minutes, I heartily recommend the series Every Rock Has a Story by Boston College Prof. Ethan Baxter.  It is wonderful for inspiring wonder and curiosity, and for introducing the scientific method, […]

Companies can employ analytics to generate insights about their output and consumption, then use the information to adapt their practices and meet a higher standard of efficiency. By Emily Folk Big data is the driving force behind the information revolution. According to estimates from […]

Good news: June 2020 was ONLY the 3rd-hottest June on record

After five consecutive months to start the year that were either the warmest or second warmest on record, June 2020 finally broke the streak by becoming only the [drumroll] third-warmest June on record. 2020’s heat has been relentless. The blazing first half of 2020 has made it incredibly likely that 2020 will finish the year as […]

NOAA: July 2020 ENSO update: La Niña Watch!

ENSO is still in neutral, and likely to continue so through the summer. However, the 50-55% chance of La Niña developing in the fall and lasting through winter means NOAA has hoisted a La Niña Watch. By Emily Becker NOAA What’s a Watch? I’ve been writing these blog posts for more than six years now, and the terminology La […]

Dr James Hansen: It’s all hunky-dory, but… Regional climate change and national responsibilities 2

Well-meaning souls, (including my friend Michael Shellenberger) rightfully concerned about the effect of “gloom-and-doom” talk on young people, say that everything is hunky-dory, climate change impacts are exaggerated (they often are) and climate change is not a serious threat (unfortunately, it is). By Dr James Hansen and Makiko Sato Let’s look at reality, real data […]

Cost of extreme weather due to climate change is severely underestimated

Over the past decade, a compelling body of evidence has linked a range of extreme weather events to human-caused climate change.  This area of research – known as “event attribution” – provides a means for climate scientists to examine how the severity and frequency of weather events, such as heatwaves, droughts and storms, are changing as greenhouse […]
