The phrase
"temperature trajectory" refers to the path or direction that the temperature is taking over a period of time. It indicates whether the temperature is increasing, decreasing, or staying the same, and helps us understand how it is changing over time.
Full definition
The emission pathway is so large that the yellow emissions floor does not affect it until 2240, and as a result the yellow and
black temperature trajectories are indistinguishable until after temperatures have peaked.
The appropriate frame is that they track * climate * — that is, the «average» warming that results from considering the many
possible temperature trajectories that reality could have taken, and which various model runs evince.
Overvaluing the influence of CH4 emissions on climate could easily result in our «locking» the earth into a
warmer temperature trajectory, one that is temporarily masked by the short - term cooling effects of the CH4 reductions, but then persists for many generations.
Regardless, if we aren't yet warmer now than in the past 125,000 years then our
current temperature trajectory means that we will get there before too long.
Four multi-decadal climate shifts have been identified in the last century coinciding with changes in the surface
temperature trajectory.
the warmest part of a day is usually in the afternoon, and the warmest days occur in the summer, but
the temperature trajectories aren't neat constant amplitude and phase sine waves.
The climate modelers calculated
the temperature trajectory over the 1900 — 2005 period both with and without CO2 and other human - induced factors.
