The entire planet sweltered to the unofficial hottest day in human recordkeeping July 3 and then blasted past that with an even hotter day on July 4, according to University of Maine scientists at the Climate Reanalyzer project.
For two straight days, the global average temperature spiked into uncharted territory. After scientists talked about Monday's dramatic heat, Tuesday soared 0.17 degrees Celsius (0.31 degrees Fahrenheit) even hotter, which is a huge temperature jump in terms of global averages and records.
