Global warming is accelerating, and chilly weather in the U.S. in April wasn't enough to reverse the planetwide trend.
Nebraska had its fourth-coldest April on record, Iowa its 13th-coldest, and the lower 48 states experienced their 23rd-coldest April. These records date to 1894.
By contrast, the planet had its 13th-warmest April on record. Globally, monthly temperatures haven't dipped below average since February 1985.
Finally, more discouraging news: Based on records dating to 1880, the Earth is in its eighth-warmest start to the year.
