Tidal locking could render habitable planets inhospitable

Tidally-locked planets - planets with one side perpetually facing their star while the other remains shrouded in darkness - tend to be warmer on one side than the other. The presence of an atmosphere can help distribute the heat across the planet, equalizing the temperatures. But tidal locking could result in wide climate variations, a result that could threaten the evolution of life on the surface of these planets.
