If human-induced climate change continues unchecked, 10 percent of the U.S. economy could evaporate by 2100, a 1,656-page federal report the White House slipped out on Black Friday (Nov. 23) warned but a nearby world has an even hotter climate problem than ours, and scientists say we could learn some valuable lessons from it.
That world is Venus, Earth's "evil twin," which was once nice enough until something went wrong and the atmosphere began trapping a little too much heat. Scientists aren't positive precisely how events played out, but the runaway greenhouse effect that resulted is beyond debate: Venus now clocks in at a staggering 880 degrees Fahrenheit (471 degrees Celsius).
"I think Venus is an important warning: Greenhouse atmospheres are not theoretical," Ellen Stofan, director of the Smithsonian's National Air and Space Museum and former chief scientist at NASA, told Space.com. And in fact, Venus has already warned us about a climate threat

"Does not affect climate". You speak with snarky absolute certainty like some pompous, know-it-all liberal. You don't know with absolute certainty how various factors affect climate on Venus. How do you know the upper level winds do not act to help distribute heat around the planet? Or act in some other ways to contribute to climate?

Climate and weather
Winds of about 224 mph (360 kph) keep the clouds of Venus in constant motion.
Though the planet spins slowly, only once every 243 Earth days, the clouds zip around the top of the planet's atmosphere every four days. But wind speeds drop closer to the surface, where they only move a few miles per hour.
On Earth, seasons change based on the planet's tilt: When a hemisphere is closer to the sun, it experiences warmer temperatures. But on Venus, most of the sun's heat fails to make it through the thick atmosphere. As such, the planet not only doesn't experience significant temperature changes over the course of the year, it also keeps things constant from night to day.
The clouds of Venus appear bright white or yellow. Unlike Jupiter or Saturn, there are no discernible bands or storms visible to the naked eye.

"It [Venus] has severe winds that blow at speeds greater than 100 m/s; although, the winds dont reach down to the surface of the planet. It has sulfuric acid clouds which send down torrents of sulfuric acid rain."

"It [Venus] is also the hottest planet in the Solar System, experiencing mean surface temperatures of 735 K (462 °C; 863.6 °F). Above the dense CO² layer, thick clouds consisting mainly of sulfur dioxide and sulfuric acid droplets scatter about 90% of the sunlight back into space.
The planet is also isothermal, which means that there is little variation in Venus surface temperature between day and night, or the equator and the poles.
The planets minute axial tilt less than 3° compared to Earths 23.5° and its very slow rotational period (the planet takes around 243 days to complete a single rotation) also minimizes seasonal temperature variation."
Well duh - How do you know the upper level winds do not act to help distribute heat around the planet?
That was my point - which you countered by claiming that the lower elevation winds had low velocity.
Goodness knows what you were thinking.
Well, duh, dude, you’re still coming across as a snarky little wise ass. Learn how to communicate properly.
Roflol. Try again.
