Republican presidential candidate Donald Trump recently slammed fellow Republican Mitt Romney, and mocked global warming.
Romney told CNN on Oct. 18 that he did not think Trump was going to be the Republican nominee in 2016, but added that it was too early to say for sure.
The former Massachusetts governor also said during an interview on Oct. 16 that some of Trump's comments were hurtful and childish, reported Business Insider.
In response, Trump tweeted on Oct. 18: "Does everyone remember @MittRomney and his famous remarks about 'self-deportation' and '47%.' He was done. I don't need his angry advice!"
Trump added in another tweet: "@MittRomney can only speak negatively about my presidential chances because I have been openly hard on his terrible 'choke' loss to Obama!"
After trashing Romney, Trump mocked notion of global warming in a tweet on Oct. 19: "It's really cold outside, they are calling it a major freeze, weeks ahead of normal. Man, we could use a big fat dose of global warming!"
Trump tweeted in January 2014: "This very expensive GLOBAL WARMING bulls--- has got to stop. Our planet is freezing, record low temps, and our GW scientists are stuck in ice."
Trump may have a fundamental misunderstanding or ignorance about global warming.
Mother Jones reported, soon after Trump's 2014 tweet, that global warming is based on trends, not weather incidents, and global warming is expected to increase the precipitation in winter storms.
Mother Jones also noted the intense heat in Australia in January 2014, which is summertime in the Southern Hemisphere.
Mashable reported on Oct. 15 that 2015 may go down as the warmest year on record.
