Discussion of climate, how it is changing, activism around that, the politics, and the energy systems change we need in order to stabilize things.
As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades:
How much each change to the atmosphere has warmed the world:

Anti-science, inactivism, and unsupported conspiracy theories are not ok here.

Until the Atlantic Meridional Overturning Circulation stops, plunging Ireland's temperatures by an average of 15°
It slows down, an effect of cold water from melting ice passing south of greenland, which has a local cooling effect, while the atlantic as a whole gets warmer. Consequence is a greater heat contrast along that front, which may intensify the sequence of low pressures bringing wind and rain, which is what Ireland has just experienced this summer. But the high-resolution models do not show that AMOC stops abruptly, that was a feature of simpler models designed to replicate palaeoclimatic changes at the end of the ice ages, when the amount of ice available to melt was much higher.
As a Canadian with Irish grandparents I look forward to claiming my Irish citizenship.
15° cooler (C or F) would be lovely.
I should have clarified 15°C, which would be a shift of 27°F. It's hard to overstate how devastating that would be to the ecology of Northern Europe, potentially sending Ireland near permafrost territory and ending agriculture and pastoralism as they know it
