Reductions In CO2 Are Impossible Without China Getting On Board

Reductions In CO2 Are Impossible Without China Getting On Board

A few years ago China agreed to discuss its runaway greenhouse gas emissions - in 2030. The Obama administration had to try and frame that as a win, noting that China had never even agreed to mention a date before.The worldwide concessions to China on emissions, and the toothless Paris Agreement, where everyone gets to pick their own way to pretend they are helping, have meant nothing is going to change. Western countries will still strive for no emissions, celebrities will buy carbon offsets they think make up for flying their private jets to environmental meetings, and it won't make any difference in the outcome. 

Mosquito Diseases Kill Tens Of Millions Per Year Worldwide But American Parents Worry More About Ticks

Mosquito Diseases Kill Tens Of Millions Per Year Worldwide But American Parents Worry More About Ticks

A few species of mosquitoes are nothing but carriers of disease, so pesticides were used to wipe them out in much of North America. Worldwide they remain a public health problem and while some ecologists claim a mythical (and scientifically debunked) 'balance of nature' and therefore insist Aedes aegypti might have some benefit, if we turned them extinct we'd have nothing but less  yellow fever, dengue fever, and Zika worldwide, the way we do in the U.S.

Xenophobia And Cake Mix

Xenophobia And Cake Mix

I live in California but my pre-Baby Boomer mother is still a Florida girl, ensconced in a nice house courtesy of my brother, with terrific neighbors who care a lot about her and kind people everywhere we go.

Robot Cockroaches Are All We Need To Make 2020 Just Peachy

Robot Cockroaches Are All We Need To Make 2020 Just Peachy

2020 started out being a weird and devastating way to end the decade yet we naively thought those Australian wildfires were as bad as it could get.Now people outside that country barely remember they happened. Because then we got coronavirus. Luckily, we dodged the murder hornets but then went right to race wars. New York, the city, county, and state, has had the worst of both COVID-19(1) and the looting, but fear not Manhattan, June is probably as bad as it gets for 2020. Well, maybe, unless July really has a surprise in store.

American Agriculture Got Us Through Coronavirus, Why Are Academic Activists Still So Down On Farming?

American Agriculture Got Us Through Coronavirus, Why Are Academic Activists Still So Down On Farming?

In November of 2019 The Atlantic asked "experts" what they would change if they could go back in time. The experts had titles like "mythographer" - no scientists invited - so it's no surprise only one response had real-world relevance.(1) A historian at Rutgers wished agriculture had never been invented. Agriculture, that fundamental progressive achievement which made food plentiful so that we no longer spent our days foraging and could learn things and, you know, create universities, had to be undone.

Some Good News: Yellowstone Won't Blow Up This Year

Some Good News: Yellowstone Won't Blow Up This Year

From Australian wildfires to COVID-19 to murder hornets to race wars in Manhattan, 2020 looks to be a challenging year. It could still get worse, but science shows it won't be due to Yellowstone blowing its top. Yellowstone is one of those scenarios doomsday "preppers" worry about. They are right to be concerned if it does happen, but they don't understand hazard (what could happen) and risk (the likelihood of the hazard) any better than environmentalists worrying about weedkillers do. 

Do No Harm? Doctors Are Giving Out 9X As Many Hydroxychloroquine Prescriptions, And That Puts People Who Need It At Risk

Do No Harm? Doctors Are Giving Out 9X As Many Hydroxychloroquine Prescriptions, And That Puts People Who Need It At Risk

The antimalarial drug chloroquine (analogue hydroxychloroquine) is also successfully used to treat lupus, rheumatoid arthritis, and autoimmune diseases said to have similar biological mechanisms as COVID-19 and, lacking any remedies besides what can be done for the flu, in March the U.S. Food and Drug Administration (FDA) granted emergency use authorization for those compounds as treatments.

Business Insider Takes A Trip Down 2019 Chemophobia Lane

Business Insider Takes A Trip Down 2019 Chemophobia Lane

Thanks to COVID-19, the public has gotten a lot more skeptical about claims that chemicals, food, and medicine are corporate conspiracies created to replace natural products that worked just fine. Even more ridiculous has been the belief that millions and millions of people are dying from these newer products even though there are no bodies to be found.Science is back, and that may be why Business Insider published what can perhaps be described as an advertorial for environmental groups who have to be sweating now that their campaigns against the modern world are being laughed at.

New Flu? Coronavirus Might Become Cause Of A Seasonal Illness

New Flu? Coronavirus Might Become Cause Of A Seasonal Illness

The flu kills over 600,000 people each year and in 2020 another virus exploded in public health circles for the third time in 17 years; coronavirus.SARS-CoV-2, which causes the COVID-19 disease, has killed nearly 400,000, and given the risk factors it is hard to say how many would have been killed by any respiratory disease, but one question is not philosophical: is this the new normal? 

Coronavirus Has Caused Democrats To Move Back Toward Trust In Science

Coronavirus Has Caused Democrats To Move Back Toward Trust In Science

A year ago, and for this entire century, the nexus of anti-vaccine beliefs and other denial of science has been Democratic states. While places like Mississippi and Alabama had vaccine rates near 100 percent, an infectious disease crisis that began on the west coast forced politicians in California, where kids without vaccines totaled more than the other 49 states combined, to shuck off their wealthiest constituents and mandate them. (1)Then COVID-19 took the world by storm and  all of that changed.

Extinction: Maybe Cro-Magnon Wiped Out Neanderthals After All

Extinction: Maybe Cro-Magnon Wiped Out Neanderthals After All

Why is Homo neanderthalensis gone while Homo sapiens have bent the world to our will? In recent years, there has been speculation that climate change wiped out Neanderthal people, or interbreeding with us, since many of us have DNA shared by Neanderthals (we also share 60 percent of our DNA with a banana) but a new paper affirms the earliest belief about survival of the fitter, commonly called survival of the fittest; competition between Cro-Magnon and Neanderthal. And Neanderthals lost.
