NEELIX: It's getting awfully hot in here.
JANEWAY: When environmental controls fail, heat from the warp plasma conduits can't be vented. Expect a heat wave before long.
NEELIX: No problem, I'm used to it. I grew up near the Rinax marshlands. Our summers were the hottest in the sector. Fifty degrees Celsius, ninety percent humidity, and the most vicious lavaflies you've ever seen.
JANEWAY: Summers in Indiana were pretty similar when I was growing up.
Macrocosm
50 degrees Celsius is 122 Fahrenheit.
The average maximum temperature in Indiana is 85.1F for July and 83.2F for August, or in the scale that Janeway uses 29.5C in July and 28.4C in August. The hottest it has ever been in Indiana was 116F/46.6C in July in 1936 and 111F/43.8 in August of the same year.
And yet for Janeway 50 degrees Celsius, a temperature I have never experienced myself though I live in extreme heat is "pretty similar" to Indiana.
Clearly the earth ended up quite scorched and even though they managed to stop it they could not reverse it back to the levels Indiana would be in today. I'd imagine my own country will be quite uninhabitable if the rise in temperature was similar across the globe.
