Sulfur dioxide may have warmed Mars, but is being considered for geoengineering on Earth. How is this possible?
So I was reading a title called Terraforming: The Creation of Habitable Worlds and came across mention of the idea that sulfur dioxide was a greenhouse gas on Mars. This can't be a mistake because I saw it elsewhere, like here. And yet at the…

Summer Winter cause
As far as I understand, there are two main reasons for having lower temperatures in winter :
shorter days, so the sun has less time to heat the earth
smaller angle of incidence, so the energy from the sunlight is absorbed in a larger area on the…

Hurricanes and Atmospheric Temperature
EDIT -- It appears that everyone is confused by the question. That's probably my fault. Let me say it another way.
Do hurricanes cool the atmosphere (by taking heat out of the ocean/air and using that energy to essentially power the winds)? Does…

Do greenhouse gasses make the world habitable?
An ageing gent says he does not accept this statement:
It's a fact that greenhouse gases, predominantly water vapour, keep the Earth
from being hostile and cold; that CO2 albeit in trace quantities is also a
greenhouse gas and therefore helps keep…

Thawing of permafrost causes positive feedback loop in greenhouse effect?
This is claimed in my climate change class, which is admittedly pretty sparse in rigorous climate physics. The reason is that there are pretty large carbon deposits in glaciers which will further the greenhouse effect which will expedite thawing…

What is a 'moist greenhouse effect'?
What is a moist greenhouse effect? I've heard that this is where all the water on a planet is quickly driven into space. However, I cannot find much information on this- is it a relatively new (or obsolete) idea and what causes it? Also, any links…

Intensity in rainfall and global warming
Why we should observe an increment on the mean intensity in rainfalls and an increment on mean dry days with global warming?

Why isn't a mirror more effective in preventing global warming than a solar panel?
In many countries, solar panels are heavily subsidized because they replace fossil fuels that apparently cause global warming. A mirror of the same size would - through a completely different effect - also reduce some global warming by reducing the…

Why do ice sheets break into such big pieces?
Another massive chunk of the Antarctic ice sheet broke free. Giant crack frees a massive iceberg in Antarctica. The article has a map that shows more cracks. It looks reasonable that they will lead to future breakup.
What sets the scale of these…

does diluting sea water from iceberg melt raise levels
I'm asking this because I just joined and am not permitted to comment on the question "Does the sea level increase if an iceberg melts?"
According google search, one liter of sea water contains 35 grams of sea salt with a density of 1027…

How much sunlight would need to be blocked to cancel out atmospheric CO2?
Atmospheric CO2 is trapping too much heat from our star's radiation. How much light would need to be blocked/reflected before reaching Earth to cancel out the excess heat being trapped by atmospheric CO2?

Greenhouse or compression?
Convection driven compressional warming is accepted here on Earth by scientists( Chinook winds, Santa Anna winds) when there is such low pressure, 1 bar = 14 psi. Scientists also agree that Jupiter’s lower atmosphere is as hot as the Sun for the…

Endothermic reactions and climate change
I have seen some questions regarding climate change. What I want to know is would generating endothermic reactions in a mass controlled state counter balance global warming and reduce heat effect energies? Therefore by using thermal energies to…

What is the actual definition and meaning of temperature anomaly, and does it make any sense?
Here is a plot of absolute temperatures in the last 2000 years:
It does not seem to show anything alarming.
Climate scientists claim that we should actually look at the temperature anomalies instead, which they claim it measures how fast…
