Climate change causes extinction
Macnamara 23 [10/28/23, Kelly Macnamara is a climate and environment correspondent @AFP, "Life on Earth under 'existential threat': climate scientists," Phys, https://phys.org/…]MZ
Climate change poses an "existential threat" to life on Earth, prominent scientists warned Tuesday, in an assessment on this year's avalanche of heat records and weather extremes that they said are hitting more ferociously than expected. With expectations that 2023 will be the hottest year on record, regions across the planet have been scorched by deadly heat waves.

Their stark assessment: "Life on planet Earth is under siege". They said humanity had made "minimal progress" in curbing its planet-heating emissions, with major greenhouse gases at record levels, and subsidies for fossil fuels soaring last year.

Debaters and coaches who switched to PrepSync — in their own words.

🏆 #1 PF Team in the Country

We won our first tournament using PrepSync. The second, we didn't drop a single ballot and won again. Two tournaments, two championships. PrepSync made the difference.

PrepSync actually totally changed the way I prep. As a small school debater I used to struggle a ton with not having enough cards to keep up with bigger schools. PrepSync has been really helpful for staying competitive while not spending hours trying to find answers to specific DAs or CPs.

PrepSync has completely sped up my prep. The search database pairs perfectly with my own research, and the Contentions feature helps me craft and expand blocks. Combined with the Blocks section, my block doc is unstoppable. CardCut speeds up my evidence research, and even when it doesn't cut exactly how I want, it highlights the key parts so I find what I need faster. The top teams are using PrepSync and having it gives you the edge to beat your opponents in round.

We hit Phil, a position we had zero prep for. In just a few seconds, PrepSync gave us enough responses to fill our rebuttal doc. It's what gave us a path to the ballot.

“I built PrepSync after watching students lose rounds, not because they lacked skill, but because prep time ran out and the right evidence wasn't there.”

PrepSync gives you four tools to fix that: search 5.5M+ cards, cut any article with AI, and browse every contention and block being run on the topic right now — so you walk in covered, every round.
