Have the oceans dissolved water vapour?
7 votes

The answer is no, yes and then, perhaps, no. No: water vapour is not "dissolved" in the oceans, rather it becomes part of the oceans through a phase change from vapour to liquid (possibly via an ...

The effect of CO2 concentration on the pH of the ocean
4 votes

Increasing CO2 concentration in the atmosphere is leading to an increasing concentration of dissolved CO2 in sea-water. The dissolved CO2 then reacts with the water to create carbonic acid, decreasing ...

Hydro-meteorological hazards vs climate extremes
Accepted answer
4 votes

The UN International Strategy for Disaster Reduction gives a good definition of a "hydrometeorological hazard": Natural processes or phenomena of atmospheric, hydrological or oceanographic nature, ...

Why don't dewdrops form on a cloudy night?
2 votes

Clouds absorb thermal radiation and re-emit it, so that some of it comes back towards the Earth (Behind the Forecast: How clouds affect temperatures). During the day this warming effect is balanced by ...

CO2 Storage, it's possible, but what about
2 votes

It is possible and there are several demonstration projects running. In Europe, the carbfix project quotes a price of $24.8/ton for carbon sequestration. Geothermal power is used to pump the CO2 ...

Why are $\small\sf{CH_4}$ and $\small\sf{CO_2}$ levels coupled during the Pleistocene?
Accepted answer
2 votes

This question is addressed in a Nature paper on "Understanding the glacial methane cycle" (Hopcroft et al. 2017). There conclusion is that changes in methane concentrations are driven by changes in ...

Is climate change a vicious circle?
2 votes

The wording of the question suggests that it is asking about what climate scientists refer to as a run-away feedback. There are, and always have been, positive feed-backs in the climate system, but ...

Frost in trees in the middle of summer (of 536)
1 votes

Frost leaves a record by damaging the cell structure, creating a "frost ring". Hadd et al discuss data on frost rings in N. American trees. There is specific discussion of the Fimbul event (...

Has irreversible global warming already begun?
Accepted answer
1 votes

Yes and no. From a pedantic point of view, the question is ill-posed: the concept of reversibility does not make sense in a chaotic system. On the other hand, it is an idea that is widely discussed, ...

Does Earth's rotation cause sea levels to increase from east to west?
Accepted answer
0 votes

The centrifugal effect of the Earth's rotation causes both sea-level and the "solid" Earth to bulge at the Equator, so that the radius at the Equator is about 22km greater than the radius at the pole ...

Derivative of Exner function
0 votes

The mistake is hidden in the identity ${\partial \over \partial z} \log (p) = {1\over p} {\partial p \over \partial z}$. This formula looks harmless and would be correct if $p$ was a real valued ...

Can minimum relative humidity be greater than maximum relative humidity?
0 votes

To calculate the minimum and maximum relative humidity you will need to measure temperature and specific humidity all through the day (the more often you measure, the more accurate it will be), ...

How could humans alter storm intensity or direction other than cloud seeding?
-2 votes

Clap your hands ... this is the human equivalent of a butterfly effect. Storm systems are chaotic, so tiny perturbations to the atmosphere grow rapidly and, eventually, alter the trajectory of future ...
