Smoke from Mariposa Detwiler Fire to impact the Valley this weekend

The San Joaquin Valley APCD has issued an advisory related to smoke from the Detwiler Fire near Mariposa.

Because of the build-up of high pressure, lighter winds, and deteriorating dispersion conditions, smoke from the fire may affect air quality in the central and southern San Joaquin Valley through the weekend.

The smoke contains particulate mater (PM2.5) that can cause serious health problems including lung disease, asthma attacks, and may increase the risk for strokes and heart attacks. Those people with existing respiratory conditions, young children, and the elderly may be particularly impacted by these conditions.

The SJVAPCD urges residents to follow their doctor's orders when exposed to PM2.5 and to stay indoors if possible, particularly if they can smell smoke or see ash in the sky.

For more air quality information about current wildfires, please refer to the SJVAPCD's wildfire page.

Three Republican Senators join with Democrats to stop Trump from eliminating an Obama climate change rule

There is hope for the environment yet as the U.S. Senate today defeated an attempt by the Trump administration to overturn a rule that regulates the emissions of methane from certain oil and natural gas production operations.

Republicans John McCain of Arizona, Lindsay Graham of South Carolina, and Susan Collins of Maine joined with their Democratic counterparts to defeat the measure by a vote of 51 - 49. The simple majority vote prevented President* Trump from using Vice-President Pence to break an anticipated 50 - 50 tie that never materialized.

Bakersfield and San Joaquin Valley win again - worst air in the nation

The American Lung Association released its Annual State of the Air 2017 report today and once again, Bakersfield and other cities in the San Joaquin Valley share the dubious "honor" of having the worst air in the country.

The report found that although continued improvement in air quality across the nation has occurred, nearly four in ten Americans - roughly 125 million - live in counties where ozone or particle pollution in the air is at unhealthy levels. The consequences of this are increased risks of developing lung cancer, heart disease, asthma, premature death, and developmental and reproductive harm.

Bakersfield, in particular, has particularly nasty air, earning the distinction of having the number one worst short-term particle pollution (24-hour PM2.5) and the second worst ozone and long-term particle pollution (annual PM2.5).

The report demonstrates that in much of the country, the Clean Air Act has successfully reduced air pollution over the last 50 years. However, as noted by Harold P. Wimmer, National President and CEO of the American Lung Association, the report "...adds to the evidence that the ongoing changes in our climate make it harder to protect human health. As we move into an ever warmer climate, cleaning up these pollutants will become ever more challenging, highlighting the critical importance of protecting the Clean Air Act."

A Nittany Lion in the lion's den, Michael Mann takes on Congressional climate change deniers

The House Committee on Science, Space, and Technology held what was ostensibly a hearing on the scientific basis of climate change today, but, according to several reports, not much happened other than name-calling.

Led by climate change denier Texas Republican Lamar Smith, the committee put noted climate change researcher Dr. Michael Mann of the Pennsylvania State University on a panel with three other scientists, Dr. Judith Curry of the Georgia Institute of Technology, Dr. John Christy of the University of Alabama at Huntsville, and Dr. Roger Pielke Jr. of the University of Colorado.

It is generally safe to say that Dr. Mann represented the overwhelming consensus of world wide climate change experts that human activity is the main driver of climate change. To say he didn't get a lot of support from those convinced that they are right and 97-98% of the world's climate change researchers are wrong may be an understatement.

Today's hearing was entitled "Climate Science: Assumptions, Policy Implications, and the Scientific Method." 

However, various news reports about the hearing referred to it as a "colossal train wreck" and a "shitstorm," a "food fight among scientists," and one where both sides were referring to each other as using tactics similar to "Josef Stalin."
