How Are Those Climate Change Resolutions Going?

Back in early January I set some Climate Change New Year’s Resolutions. At the time, I had no idea that the COVID-19 pandemic would occur and that life, in many ways, would be radically changed. However, although COVID-19 has contributed to a global reduction in carbon emissions (relative to 2019), it is clear that there is still much work to do when it comes to making the sorts of emissions …

The unusual relationship between climate and pandemics

Well-documented torrential rains and unusually cold temperatures affected the outcomes of many major battles during World War I from 1914 to 1918. Poet Mary Borden described the cold, muddy landscape of the Western Front as “the liquid grave of our armies” in her poem “The Song of the Mud” about 1916’s Battle of the Somme, during which more than one million soldiers were killed or wounded.

The Story of More, by Hope Jahren

Humanity faces a crisis today, and we struggle to find the right way to deal with it, to solve it, to live meaningfully within the constraints it imposes. You might think I’m referring to coronavirus, but it’s actually climate change that’s on my mind. Hope Jahren, author of the incandescent Lab Girl, has a new volume out, on the unsustainability of modern Western life, and what actions we can take …

Darkness, not cold, likely responsible for dinosaur-killing extinction

New research finds soot from global fires ignited by an asteroid impact could have blocked sunlight long enough to drive the mass extinction that killed most life on Earth, including the dinosaurs, 66 million years ago.

Lake Erie is Nearly Frost-Free

For the past couple of days, we’ve been lucky to have some all-too-infrequent sunny days, giving us some sunshine to lift our spirits and send us searching for our sunglasses. The clear weather is also a good time for an updated MODIS image of the Lake Erie Basin. The image above shows the lake is nearly ice-free except for some narrow shoreline areas in the western basin. The surface water …

Discovering Europe’s History Through its Timbers

An analysis of timber used to construct buildings in Europe hundreds of years ago is giving scientists and historians new insights into the region’s history from the 13th to 17th centuries. Using samples of wood taken from old buildings in Europe, Fredrik Charpentier Ljungqvist, a historian and paleoclimatologist at Stockholm University, and Andrea Seim, a dendrochronologist at the University of Freiburg, figured out when the trees used in the buildings …

E25 – Antarctica’s Oldest Ice

Drilling engineer and ice core scientist Robert Mulvaney has driven thousands of kilometers over Antarctica in the past few years in a snow tractor, creeping slowly over one of the highest points of the ice sheet, near a location known as Dome C. He’s looking for the perfect place to drill one and a half million years into the past.

Climate Change Resolutions

Happy New Year, everyone! This year, I am not worrying about stereotypical New Year’s resolutions, such as trying to exercise more or learn a new language. Instead, I am making some climate change resolutions. That is, I am making some resolutions to lower my environmental (including carbon) footprint. These resolutions are not perfect — there is certainly much more that I could do to lower my footprint. However, I have …

Donate to Help Australia – and I’ll Send You an Aussie Postcard

I moved to Australia last year, and I am very happy and proud to be living in this incredible country. Recently, my heart has been breaking as I hear about the Australian bushfires, which are catastrophic and have grown much worse over the past couple of weeks. The extreme nature of the fires is no doubt due to climate change, as explained, for example, here and here. I live in …

Monitoring conflict and climate could help stop famines before they happen

Deaths due to famine have fallen precipitously in recent decades, but undernutrition, which affects one in five children worldwide, remains rampant. Now, researchers are using satellite imagery and social media to detect food-scarce regions before they become full-blown crises.

Climate change driving expansion of Lyme disease in the US

A new study finds increasing average winter temperatures are driving up reported Lyme disease cases in the Northeast and Midwest, especially near the outer limits of tick habitats where warmer winters boost tick survival rates and ability to find hosts. Public health officials are even seeing the disease spread to parts of Canada, in areas where it has never been seen before.
