I think this is the one https://www.energy.gov/sites/default/files/2025-07/DOE_Criti... It is really just a collection of 'skeptic' arguments form the last 20 years or so. Science …

I would say we are largely past the second threshold too (that the warming is human caused). The last IPCC report had as the first statement in the summary for policymakers (from W…

I think part of the IMO2020 compliance is that fines have actually been applied for ships that have broken previous similar regulations. https://www.theguardian.com/world/2018/nov/…

One thing I found really interesting abou the Graphcast paper (I appreciate this is not graphcast, but I think it is still relevant) is that it doesn't understand climate change. T…

I think the one time bump could be a fair description in that is doesn't add to the long term warming rate in the same way GHGs do. The cumulative effect here is pretty much all re…

The wording of the article and the paper are a bit misleading here. It is definitely a one time even (although it plays out over 20 years) The doubling of the rate of warming only …

The mechanism is different from the impact of sulphur in the stratosphere (where there are no clouds), but it is the same as the mechanisms that have caused the majority of the aer…

The numbers in this study need to be interpreted carefully, the way the authors presented them doesn't really help this. The warming rate they quote (0.24K per decade) is the insta…

Water vapour is a very strong infrared absorber, so much so that it is more important for the greenhouse effect than CO2. However, it is usually very difficult to change the amount…

The increase in humidity is actually a different effect - evapotranspiration from trees is included in climate models (along with their response to increasing CO2 concentrations) […

This is related to my reply above, but clouds in general move heat upwards in the atmosphere through latent heating. When you evaporate water from the surface, you cool it (like sw…

Maybe I should describe my job differently...

It heats up the atmosphere and eventually gets emitted back into space! For the Earth's temperature to remain approximately constant, the energy leaving the system (as infra-red) h…

As a "cloud person", I just want to add a few things to the description of how clouds affect the climate (and why high clouds have a wamring effect). All clouds are white, so they …

The PR part also applies to Earth Observation Satellites (ESA and EUMETSAT). (Almost) any time you see a wide area picture of the Earth from Space (particularly around a weather ev…

I thought that aircraft could use much more than 5%, but that the maintenance regime was different - e.g. [1]. Current engines assume a proportion of impurities and are tuned to wo…

I suspect it will at least be publicly available, although there might be some terms attached (I don't know). SEVIRI (the current instrument) has data available through the EUMETSA…

The new imager (FCI) will be fantastic for studying the atmosphere, particularly clouds and aerosols (like desert dust). The older imager (SEVIRI) didn't have a blue channel, so al…

There were a few Earth Observation missions that didn't make orbit about 10-15 years ago. This was due to a failure of the Taurus-XL fairing separation. The orbiting carbon observa…

Organisations aiming to reduce sulpfur in ship fuel are defiitly aware of the cooling impact it has on the climate. However, the health benefits of this reduction are not to be und…

Another way to think about it is in terms of average person years American: ~15 tonnes CO2 per year - 126 years European: ~10 tonnes CO2 per year - 190 years World average: ~5 tonn…

I understand where you are coming from and agree that we need to know more about this to do it properly if required. However, I think some of this reflex is jusified by the known s…

Just to add that the majority of geoengineering methods currently proposed - particularly those that reduce absorbed solar radiation (such as stratospheric sulfate and marine cloud…

Water provides the 'energy' that drives many storms. As a bubble (or parcel) or air rises, it cools. Eventually it gets cold enough to condense water (some of which forms rain). Th…

I am not entirely sure what a cliamte change absolutist is, but have you thought of the possibility they might be right? Obviously we have had extreme weather before, but many of t…
