    New, Infectious Coronavirus Is Detected In Malaysia – Possibly Coming From Dogs

    New Coronavirus Detected In Patients and the Source May Be Dogs

    No one wants to hear news about a coronavirus. We are tired of it. But, the more we know the better we can try to live. This news comes from Malaysia where scientists have connected a coronavirus in dogs that might be transmitted to humans.

    In the past 20 years, new coronaviruses have emerged from animals with remarkable regularity. In 2002, SARS-CoV jumped from civets into people. Ten years later, MERS emerged from camels. Then in 2019, SARS-CoV-2 began to spread around the world.

    For many scientists, this pattern points to a disturbing trend: Coronavirus outbreaks aren't rare events and will likely occur every decade or so.

    Wildfires Made California Air Quality Among Worst in the World in 2020

    Wildfires Made California Air Quality Among Worst in the World in 2020

    2020 was a bad year for many reason but most saw air quality improve in much of the world, except California. Pandemic lockdowns helped improve air quality worldwide in 2020, the U.S. saw its air quality worsen — particularly on the West Coast — thanks largely to record-setting wildfires and toxic smoke.

    Southern California dominated the list of most polluted U.S. cities in 2019, the fires of 2020 moved that distinction to Central and Northern California, according to the annual report released Tuesday, March 16, by IQAir, a Swiss company that has partnered with the United Nations to create the world’s largest air-quality data platform.

    Wildfire Smoke is up to 10X More Harmful than Other Air Pollution

    Wildfire Smoke is up to 10X More Harmful than Other Air Pollution

    Thick smoke from record wildfires covered Northern California last summer and fall. It turned the Bay Area skies an alien orange color, raising health concerns over a hazard that is increasing as temperatures continue to climb and poorly managed forests burn out of control each year across the West. more...

    What is the Changing Risk and Burden of Wildfire in the United States?

    What is the Changing Risk and Burden of Wildfire in the United States?

    A new study published by the Proceedings of the National Academy of Sciences of the United States of America (PNAS) is predicting a grim future for wildfires and the resulting toxic smoke. 

    Over the past four decades, burned area from wildfires has roughly quadrupled in the United States. This rapid growth has been driven by a number of factors, including the accumulation of fuels due to a legacy of fire suppression over the last century and a more recent increase in fuel aridity shown for the western United States), a trend which is expected to continue as the climate warms.

    These increases have happened parallel to a substantial rise in the number of houses in the wildland–urban interface (WUI). Using data on the universe of home locations across the United States and updated national land cover maps, we update earlier studies and estimate that there are now ∼49 million residential homes in the WUI, a number that has been increasing by roughly 350,000 houses per year over the last two decades.

    How Does Wildfire Smoke Impact a Dog's Health?

    How Does Wildfire Smoke Impact a Dog's Health?

    Wildfires in the western United States this year have already proved to be massive and stunning. Wildfires burning across California, Oregon, Colorado, and Washington are producing soot, ash, and smoke filling the air amid searing heat. Thick clouds of ash particles are wafting over cities and rural areas turning the Bay Areas’ sky orange? The tiny particles that comprise smoke are scattering the longer light wavelengths of reds and oranges to overwhelm the shorter wavelengths of blue, dimming the...
