I'm a bit doubtful that it (assuming there is an "it") takes more than 1.5 years? 18 months is 30% of five years. A process that takes X amount of time can't really take Y >> X amount of time to get going. >we are still lagging on the expected heating due to occur due to increased thermal insulation from CO2 released into the troposhere five years ago I thought it's being widely reported - this year - that we seem ahead of the warming trend, breaking all sorts of records, etc. As is mentioned in almost every article about climate change ad nauseum, global temperature increases measured in degrees are small but involve huge amounts of energy, and typically there is said to be a linkage to massive disruptions and suffering. So saying this temporary source of warming is very small and unnoticeable seems rather equivocal. You can say it, but what is it meant to communicate? Small and unnoticeable on your thermometer is literally true of the primary trend from CO2, but if you go around belaboring that, you sound like a denier.

> A process that takes X amount of time can't really take Y >> X amount of time to get going. A fully laden iron ore carrier 1 km in length with 100's of thousands of tonnes of mass can drift slowly toward your ore wharf and take an hour to first touch it. The destruction of that jetty can be over in 20 minutes. There's a lag time of 60 minutes on an event that lasts 20 minutes. > I thought it's being widely reported - this year - that we seem ahead of the warming trend, breaking all sorts of records, etc. Right now the global average tempreture is higher than it's been in recorded history. This is caused by greater insulation in the atmosphere trapping heat that is normally reflected outwards in the thermal band - that insulation is greater CO2. Here's the thing; were we to magically stop ALL CO2 emissions right now today and hold steady .. the global average tempreture would still continue to rise for many many years (smoothed over thhe usual decadal oscillations) until an equilibrium was reached .. that's the lag time. You may be familiar with a similar lag on a cold night when you throw an extra blanket or six on the bed and you're not instantly warm .. it takes some time for your body heat to warm up the area under the blanket. A good starting palce for all this is the heat equations - heat flows like a fluid, it takes time to travel through mediums such as metal bars, it takes to to radiate heat away, etc.
