With help from the hottest July on record and 16 straight months of above-average temperatures, the US is on track to post its hottest year in history, reports NBCNews.com. In fact, the only way we can miss the mark is if the final three months of the year get seriously cold and add up to one of the top 10 coldest quarters in history. Don't bank on it. A weather.com meteorologist tweeted today that there's only about a 7% chance that the US won't set the hottest-ever mark. Records started being kept in 1895.
