The Beer Lambert Law mentioned by Don Young (Feb. 24) applies to the absorbency of visible light radiation, not heat radiation. Contrary to Young's assertion that Beer Lambert negates climate science, Beer Lambert is actually irrelevant to climate change since climate change involves the trapping of heat; hence the term "global warming." If our planet is to remain healthy, energy we receive from the sun must be in balance with energy emitted back into space.
What Young seems not to understand is that warming is a result of incoming visible radiation passing through the atmosphere (Beer Lambert states it should), its being transformed at the Earth's surface into heat radiation, and then this heat radiation passes back outwards through our atmosphere. When this outwardly radiating heat energy is trapped (doesn't make it back to space) by methane, nitrous oxide, ozone, carbon dioxide and water vapor, we get global warming.
Ms. Shawkat suggested that climate-change deniers check the science. Young failed to heed this advice. The Beer Lambert Law cannot be used to negate climate change. Life on Earth depends on the balance of incoming and outgoing energy radiation. The voices of future generations demand we act. — Paula Perez Costas, Ashland
Good for House Minority leader Nancy Pelosi for standing up for the Affordable Health Care Act. The time is now for serious push-back against the naysayers and Koch brothers' propaganda.
The law makes getting health care more affordable, more accessible, and mandates better coverage. The groups that benefit directly are those young people who can get on their parents' plan, people with pre-existing conditions, women who will no longer have to pay higher premiums, those who are entering or re-entering the individual marketplace, and the poor who now qualify for Medicaid if their state has approved accepting the federal expansion. There are many more people now who are on the bus, not off it.
You won't see the Koch brothers making an ad about the Hispanic couple in Texas who spent two hours filling out paperwork only to be told they earned too little to qualify for a subsidy. And because Texas has declined to accept Medicaid expansion, they will be going to the emergency room for care.
Corrections are being made. The federal website is working and adjustments have been made for special cases. This cup is mostly full, not empty. No reason to turn back. — Steve Haskell, Ashland
With all due respect to Mr. Maddux, lowering the speed limit on Foothill Road will unfortunately not help lower the number of accidents as much as he would like to believe.
What would truly help is if drivers would pay attention. It is astonishing to me how many people continue to text and talk on their phones while driving. I also see people engaging in animated conversations with passengers (as indicated by the silhouette of their arms moving about and their head consistently turning to the right), not using turn signals, failing to turn on headlights and weaving all over the road.
The problem remains that when many people are driving their vehicles they are focused on doing everything but just that. Speed limit changes also do not deter intoxicated or impaired drivers. The bottom line is people need to pay attention and drive as safely as possible, instead of focusing on multi-tasking while behind the wheel. — Andrea Noble, Medford
