weather

it's been hot.

it's been getting hotter this century, but this year is something else.

Summer just started, and it's too early to crunch the numbers, but the past week's extreme temperatures - including successive broken records for highest ever national average - exceed the predictable variability, indicating a climate factor.

If the dust settles and the statisticians can indeed 'see' a climate change fingerprint in the summer's weather, it suggests that further impacts are already 'locked in'.
