The Earth is likely to get relief in 2017 from record scorching temperatures that bolstered governments' resolve last year in reaching a deal to combat climate change, scientists said on Wednesday.

July was the hottest single month since records began in the 19th century, driven by greenhouse gases and an El Nino event warming the Pacific. And NASA this week cited a 99 percent chance that 2016 will be the warmest year, ahead of 2015 and 2014.

In a welcome break, a new annual record is unlikely in 2017 since the effect of El Nino - a phenomenon that warms the eastern Pacific and can disrupt weather patterns worldwide every two-seven years - is fading.
