Defending climate in the age of Covid 19.

As Kermit the frog famously said, “It isn’t easy being green.” And, in a world which is, by necessity, now consumed in the battle against a pandemic, it’s even harder. It’s almost as if that other “existential threat,” manmade climate change, has been forgotten, even tho it never really received the attention it deserved in the first place!   It’s both encouraging and bewildering to watch just how this latest, terrible and unprecedented chapter in our history, is playing out;   E ncouraging because so many of us are actually heeding the advice of our best minds in epidemiology by hand-washing, physical-distancing and self-isolating. This is surely saving countless lives from the deadly maw of the “Covid beast.” By contrast, our climatologists - who’ve been warning us for a generation that our planet is on a dangerous trajectory toward “hothouse Earth” if we don’t eliminate or drasticall

Catastrophic changes Planet Earth is undergoing today likely mirror many of those which happened hundreds of millions of years ago. The big difference? Volcanoes - not humans - were likely the main drivers of the changes back then.

NATURE The amount of CO 2  released into the end-Triassic atmosphere from volcanic eruptions was likely comparable to the projected total amount of anthropogenic (manmade) CO 2  that will be emitted during the 21 st  century. The findings are published in  Nature Communications . Such large volumes of volcanic CO 2  likely contributed to end-Triassic global warming, sea level rise, and ocean acidification. The end-Triassic extinction (approximately 201 million years ago) resulted in the demise of large proportions of all marine and terrestrial species. It is thought that this extinction was caused by dramatic climate change and rising sea levels which, are known to have occurred at that time. Volcanic CO 2  released during the large volume Central Atlantic Magmatic Province eruptions has been considered as an important contributor to the process, but this is debated. Manfredo Capriolo and colleagues found evidence of abundant CO 2  in basaltic rocks from the end-Triassic Ce

Climate change poses 'lifelong' child health risk

Phys Org It's feared that a changing climate may be providing improved conditions for the mosquito which spreads the zika virus, sometimes responsible for severe brain conditions in infants like this. Climate change will damage the health of an entire generation unless there are immediate cuts to fossil fuel emissions, from a rise in deadly infectious diseases to surging malnutrition, experts warned Thursday.

--> by Larry Powell This is the Ashcroft Reserve fire in BC in 2017. That was the worst year ever for wildfires in that province - until this year!  Photo by Shawn Cahill. As I write this, human bodies incinerated beyond recognition, are being pulled from the ruins of wildfires in California. More than a thousand people are either missing or confirmed dead, with property damage set to top several billions of dollars. Smoke from the fires has now enveloped San Francisco. President Trump blames "poor forest management,"and, after first threatening to withhold it, finally grants emergency aid. His critics take him to task for his lack of empathy for the victims. After visiting the fire zones, he continues, disgracefully, to deny the role manmade climate change is surely playing here. But what's worse, his absence of a heart (which has been evident for some time), or his actual  policies  which have shown him to be
