He has not really addressed the fact that the notion of climate, as distinct from the notion of
weather, is not concerned with particular features of a single trajectory or history, but with the fact that there are some general features about certain kinds of time and system
averages over many trajectories - and that these
average features tend to show certain kinds of regularity or slow secular variation that are not apparent in a single trajectory (the
term secular here has a technical meaning, not the common one of «not religious»).

weather measured over a period of several decades.

weather is always changing, especially over the short
term, climate is the
average of
weather patterns over a longer period of time (usually 30 or more years).
Because
weather patterns vary, causing temperatures to be higher or lower than
average from time to time due to factors like ocean processes, cloud variability, volcanic activity, and other natural cycles, scientists take a longer -
term view in order to consider all of the year - to - year changes.
Short
term fluctuations in the
weather such as North Atlantic high or an El Nino will affect climate figures for a year or two — but not
averages over the 10 - 15 year scale.
Climate change (as the
term implies) is a change to the climate, which is really a change to the
average of the
weather.
Climate - Climate in a narrow sense is usually defined as the
average weather, or more rigorously, as the statistical description in
terms of the mean and variability of relevant quantities over a period of time ranging from months to thousands or millions of years.

term average of
weather, over many years.

terms of
weather, environmental health, extreme events, snow, rain drought and flood, the impact of a global
average is trivial or less.
Water vapor, which is a greenhouse gas, albeit short lived, and a component of and response to
weather conditions — but not, being so ephemeral, a driver of much longer
term weather patterns (or climate)-- and due to it's heavy prevalence the greenhouse gas that is on
average responsible for more re ra - radiated heat than any other, in fact is not warming, but cooling.
