In three days, #COP30 starts in #Belém, Brazil, let’s remember that climate action isn’t just about climate - it’s also a good way to clean the air we breathe.
Many of the steps we take to tackle #climatechange can also bring immediate air-quality benefits.

Should we start historical climate simulations in 1750 (or 1800) rather than 1850?
Importance of beginning industrial-era climate simulations in the eighteenth century

At a workshop today discussing improving historical weather & climate reconstructions for the British & Irish Isles.
Key questions: if you had a high resolution reanalysis for these islands, what would you want to use it for? What complementary observational datasets should be prioritised?

New study in Nature by Lin et al shows how the sea-level rise from the melting Ice Age ice (a total of 120 meters rise) ended thousands of years ago.
Until our fossil fuel use started a new phase of rising seas.

How would a major hurricane that hit Jamaica in 1903 be different today, in a warmer world?
It would drop more rain. (At least)

STRENGTH: Warmer water is hurricane food
RAINFALL: Warm air holds more water vapor
SURGE: Warmer water expands, warmer ice melts, sea levels rise

As Hurricane #Melissa approaches Jamaica, we look back to a similar event in August 1903.
The rainfall from that storm would have been more intense in today’s warmer climate.
#Melissa will likely drop more rain now than it would have done a century ago.

In August 1903 a cat 3 hurricane hit Jamaica causing significant damage.
Our reanalysis-based approach (esd.copernicus.org/articles/14/...) can examine how that storm would be different in a warmer world like today.
Then & now precipitable water fields show heavier rain would be likely.

Data rescue, often by digitizing old paper records, is one of the ways that climate science research improves our understanding of the recent past.
It's hard to know how much useful data is still hiding in unremarkable paper volumes in a government warehouse somewhere.
