A NEW PAPER by researchers at UW-Madison paints a stark picture of climate changes taking place. The study said greenhouse gases are at the highest mark in human history.

Levels of heat-trapping greenhouse gases have surpassed those from any point in human history and by 2030, are likely to resemble levels from 3 million years ago, when sea levels were more than 60 feet higher than today, and the Arctic was forested and largely ice-free.

Speaking of the current global warming debate, here’s an astute observation. It may be some time before it’s known how much hot air of the current political environment has contributed to global warming.

Over my 48-year newspaper career, I’ve collected hundreds of interesting bits of wisdom. If that’s true, why am I not a lot wiser? Here are a few that you might enjoy. They never seem to go out of style. Maybe that’s why they persist?

A considerate wife is one who doesn’t laugh out loud when her husband’s lodge names him “illustrious supreme master.”

A long, cold winter is when you retract all the nasty things you said about a summer of record heat and humidity.

You can almost bet the guy who was always late for school will show up at the “open bar” two hours before all others for the class reunion.

Remember back when the star high school athlete’s only compensation was a letter sweater?

Good health is merely the slowest possible rate at which one can die. Health nuts are going to feel stupid someday, lying in the hospital, dying of nothing.

How come the woman who says she has nothing to wear needs the most closet space?

How come they don’t call municipal police department detectives “public eyes?”

You know you’re getting old when nobody tries to talk you into anything except buying extended-care health insurance.

All of us could take a lesson from the weather. It pays no attention to criticism.

Some people have the nerve to drive slightly over the speed limit, thus requiring them to use the slow lane.

How come the first arrivals in church are always those who want to sit at the end of the pew?

Not too happy about the way things are going on the sexual equality front is the guy who sees a young woman driving the pickup truck he’d like to own, but can’t afford the $55,000 sticker price.

I remember back when the only kind of organ donor was a person who gave one to the church.

Give a person a fish and you feed them for a day. Teach a person to use the internet and they won’t bother you for weeks, months, maybe years.

A good neighbor is one who is as generous with his tomatoes as he is with his zucchini.

Horse sense may have been the reason there were few head-on collisions before the invention of the automobile. How will this thought change when there are driverless cars?

How did children (in fact, all of us) ever learn to make decisions in a world with only three ice cream flavors and three TV stations?

As the quest goes on for more mileage-efficient cars, has anyone thought of making one that won’t exceed the speed limit?

Inequities in our judicial system result in petty crooks being sent to jail while bigger ones are sent to Madison, Columbus and Washington.

Here’s a timely one. You have to feel sorry for the person who is trying to provide a college education for his children, while still paying for his own student loans and will likely be forced to assume his grandparents’ college loans.

We could save a lot of tax money by basing congressional pay off productivity.

An efficiency expert is a person brought in at great expense to corroborate what the janitor has always said.

You’re probably sicker than you think if you don’t get ribald “get well” cards.

How come a child who has no problem operating a smartphone and programming a satellite TV remote needs help with homework? Ask Siri that one.

A wise homemaker will save considerable money on food costs by buying only vegetables the children won’t eat. The same theory applies to buying foods that don’t contribute to childhood obesity.

Remember back when you could talk to the telephone operator free of charge? School children today don’t remember a time without cellphones and tablets.

It would be nice to relive those innocent days when the most common substance abuse among kids was chewing gum in class.

I know a few (million) Americans who could learn from this one. The man who does the rowing seldom has time to rock the boat.

We have way too many people riding in the wagon and not enough pulling it.
