starting a new book - so far the writing is phenomenal.

it's about how the world operates in terms of #energy (and #CO2), food, and materials, and, from the reviews, it appears to have sparked lots of #debate

Manitoba is ending some of its #hydroelectric #electricity exports to the US and redirecting that energy for domestic ๐Ÿ‡จ๐Ÿ‡ฆ development and to offset reliance on #fossilfuel / diesel power in northern communities.

The amount #electricity being redirected is around 500MW - this is an amount of power roughly equivalent to the power of the upcoming Rolls-Royce small modular #nuclear reactor (SMR).

some days are just like this

Two people walk under umbrellas across a rain-slicked city street, with reflections shimmering on the pavement. Warm light spills from nearby shop windows, contrasting with the cool, gray atmosphere of the overcast sky. Distant trees and buildings line the background, adding depth to the quiet urban scene.

Two days ago, the #pollen count in #Atlanta #Georgia reached a record-breaking high level of 14801 (atlantaallergy.com/pollen_coun) - the highest level the area has ever seen

Record-high CO2 levels amplify pollen production in trees - another clearly visible impact of #ClimateChange ๐Ÿคง๐Ÿ˜ญ

@Undead_Zeratul ya same I recently started getting back into it - I'm currently building a commander deck around this shark pirate guy, which benefits off of cards with discard costs

Captain Howler, Sea Scourge
Legendary Creature โ€” Pirate Shark
Wardโ€”{2}, Pay 2 life. Whenever you discard one or more cards, target creature gets +2/+0 until end of turn for each card discarded this way. Whenever that creature deals combat damage to a player this turn, you draw a card.
