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

Someone needs to plant some trees on Venus.
Another data point showing that high temperatures lead to an abundance of CO2, not the reverse.
The planet Venus is often referred to as Earths Sister Planet, and rightly so. In addition to being almost the same size, Venus and Earth are similar in mass and have very similar compositions (both being terrestrial planets). As a neighboring planet to Earth, Venus also orbits the Sun within its Goldilocks Zone (aka. habitable zone). But of course, there are many key difference between the planets that make Venus uninhabitable.
For starters, its atmosphere over 90 times thicker than Earths, its average surface temperature is hot enough to melt lead, and the air is a toxic fume consisting of carbon dioxide and sulfuric acid. As such, if humans want to live there, some serious ecological engineering aka. terraforming is needed first. And given its similarities to Earth, many scientists think Venus would be a prime candidate for terraforming, even more so than Mars!
Over the past century, the concept of terraforming Venus has appeared multiple times, both in terms of science fiction and as the subject of scholarly study. Whereas treatments of the subject were largely fantastical in the early 20th century, a transition occurred with the beginning of the Space Age. As our knowledge of Venus improved, so too did the proposals for altering the landscape to be more suitable for human habitation. ...

If I decide on tennis lessons Venus will be my go-to.
Until then leave me alone.
If that was published today, she would be transgendered to a he.
Well clearly the Venusian didn't believe in globull warming and kept driving their SUVs. The fate of non-believers!
Yup!
Nasty place. But it has some natural resources that immediately available unlike Mars.
Global warming alarmists ignore the biggest greenhouse gas of all, water vapor, which holds more heat and is in the air in a much higher percentage than CO2.
Works for me
I heard the Venisians stopped all production, paid the astronomical taxes to their global government, all killed themselves... to no avail... it STILL didnt save them from “CLIMATE CHANGE”!!!!
The average mean temperature on Earth is around 57 degrees F, whereas the average temperature on Venus is 864 degrees F! There is no way to contrast and compare temperatures between the two planets with such discrepancies in their surface temperatures and locations in proximity to the Sun.
So, greenhouse [effect] is all about carbon dioxide, right?
Wrong. The most important players on the greenhouse stage are water vapor and clouds [clouds of course aren't gas, but high level ones do act to trap heat from escaping, while low-lying cumulus clouds tend to reflect sunlight and thereby help cool the planet -etl]. Carbon dioxide has been increased to about 0.038% of the atmosphere (possibly from about 0.028% pre-Industrial Revolution) while water in its various forms ranges from 0% to 4% of the atmosphere and its properties vary by what form it is in and even at what altitude it is found in the atmosphere.
In simple terms the bulk of Earth's greenhouse effect is due to water vapor by virtue of its abundance. Water accounts for about 90% of the Earth's greenhouse effect -- perhaps 70% is due to water vapor and about 20% due to clouds (mostly water droplets), some estimates put water as high as 95% of Earth's total tropospheric greenhouse effect (e.g., Freidenreich and Ramaswamy, 'Solar Radiation Absorption by Carbon Dioxide, Overlap with Water, and a Parameterization for General Circulation Models,' Journal of Geophysical Research 98 (1993):7255-7264).
The remaining portion comes from carbon dioxide, nitrous oxide, methane, ozone and miscellaneous other 'minor greenhouse gases.' As an example of the relative importance of water it should be noted that changes in the relative humidity on the order of 1.3-4% are equivalent to the effect of doubling CO2.

Water Vapor Rules the Greenhouse System
Water vapor constitutes Earth's most significant greenhouse gas, accounting for about 95% of Earth's greenhouse effect (4). Interestingly, many 'facts and figures' regarding global warming completely ignore the powerful effects of water vapor in the greenhouse system, carelessly (perhaps, deliberately) overstating human impacts as much as 20-fold.
Water vapor is 99.999% of natural origin. Other atmospheric greenhouse gases, carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and miscellaneous other gases (CFC's, etc.), are also mostly of natural origin (except for the latter, which is mostly anthropogenic).
Human activities contribute slightly to greenhouse gas concentrations through farming, manufacturing, power generation, and transportation. However, these emissions are so dwarfed in comparison to emissions from natural sources we can do nothing about, that even the most costly efforts to limit human emissions would have a very small-- perhaps undetectable-- effect on global climate.

Water Vapor Confirmed As Major Player In Climate Change
ScienceDaily (Nov. 18, 2008) Water vapor is known to be Earth's most abundant greenhouse gas, but the extent of its contribution to global warming has been debated. Using recent NASA satellite data, researchers have estimated more precisely than ever the heat-trapping effect of water in the air, validating the role of the gas as a critical component of climate change.

How did this woman secure any position of authority, or establish any credibility in the scientific community, with fraudulent garbage like this?
But, but we had visitors from Venus back in the late 1950s! I read a book on it!
Not based on fact, but close enough for gov't 'work'. Thanks ETL.

Venus can be cooled down via the addition of a LOT of water, most of which would eventually disappear (with the heat) into high altitude geysers. But the planet has a retrograde rotation on its axis, and takes more than a Venerian year to make one full rotation. So, unless the rotation rate can be increased (even in a retrograde direction, although that isn't going to work long-term because of the tidal transfer of momentum), the only way Venus can be made workable for Earth life (and probably not for humans) would be the further addition of water, turning the surface into a global ocean. And cooling it down would take centuries, probably thousands of years.
Someone just like her does the hiring.
DUH. Venus is closer to the SUN! More heat to retain. Venus has nothing to teach us.
