Politics Trump Mocks 'Snowman(woman)' Amy Klobuchar's 2020 Run Speech — and She Claps Back with Hair Dig Sen. Amy Klobuchar is already taking on President Trump on Twitter, responding to his tweet about her appearance and global warming By Nick Maslow Nick Maslow Instagram Twitter Senior News Editor, PEOPLE People Editorial Guidelines Published on February 11, 2019 11:38 AM Share Tweet Pin Email Photo: Mustafa Yalcin/Anadolu Agency/Getty; Stephen Maturen/Getty The 2020 Democratic presidential primaries are still a year away, but Minnesota Sen. Amy Klobuchar is already showing she can navigate President Donald Trump‘s personal attacks with wit. Announcing her 2020 presidential campaign as snow blanketed Minneapolis on Sunday, Klobuchar became covered with flakes, from her hair to her coat, as she discussed several political issues that have inspired her bid for the White House — including climate change. It didn’t take long for Trump, 72, to tweet about his potential 2020 rival: “Well, it happened again. Amy Klobuchar announced that she is running for President, talking proudly of fighting global warming while standing in a virtual blizzard of snow, ice and freezing temperatures. Bad timing. By the end of her speech she looked like a Snowman(woman)!” Meet the 2020 Presidential Candidates — So Far! Sen. Amy Klobuchar announcing that she is running for president. Stephen Maturen/Getty Klobuchar, 58, responded with a dig of her own: “Science is on my side, @realDonaldTrump. Looking forward to debating you about climate change (and many other issues). And I wonder how your hair would fare in a blizzard? ☃️Everyone else can join my team and contribute at amyklobuchar.com.” Cold weather in one part of the world does not disprove global warming, according to scientists. “It’s like saying, ‘If everyone around me is wealthy, then poverty is not a problem,’” Peter Frumhoff, director of science and policy and chief climate scientist at the Union of Concerned Scientists, told CNN after Trump tweeted about climate change in 2017. “Weather refers to the conditions in the atmosphere over a short period of time, whereas climate refers to trends in atmospheric patterns over a much longer timescale,” Dr. John Fleming, a climate scientist with the Center for Biological Diversity, told Accuweather. “This is well expressed as an analogy: weather is like your mood, whereas climate is like your personality,” Fleming continued. “This is why it is possible to have unusually cold weather across much of the U.S. [during] winter, while observing that globally, surface temperatures have been steadily rising,” he added.

Cory Booker Announces He’s Running for President in 2020: ‘Together, America, We Will Rise’ Indeed, 2018 was the fourth-hottest year on record, according to NASA and the National Oceanic and Atmospheric Administration, NBC News reported earlier this month. Though snow was falling during Klobuchar’s speech in Minnesota on Sunday, record-breaking, “unprecedented” heat has been impacting Australia, Chile and Argentina this February during summer in the southern hemisphere, reported USA Today. During her speech on Sunday, Klobuchar, a third-term senator, said she would work to reverse Trump’s policies, should she win the Democratic nomination and win the White House next year. Her initiatives would include rejoining the Paris climate agreement. “For too long, leaders in Washington have sat on the sidelines while others try to figure out what to do about our changing economy and its impact on our lives, what to do about the disruptive nature of new technologies, income inequality, the political and geographic divides, the changing climate, the tumult in our world,” Klobuchar said in her announcement, according to the New York Times. “Let’s stop seeing those obstacles as obstacles on our path,” she continued. “Let’s see those obstacles as our path.” Though Klobuchar is admittedly a tough boss — “I have high expectations,” she told the Times in November — the newspaper on Sunday noted her “her popularity at home.” Elizabeth Warren Announces Run for President: ‘This Dark Path Doesn’t Have to Be Our Future’ Alex Wong/Getty Images “Despite the distinctly Minnesota weather, supporters turned out by the thousands on Sunday, cramming into a riverfront park wearing snow pants, ski goggles and parkas. Some arrived on cross-country skis or brought dogs wearing coats,” the Times reported, suggesting Klobuchar can compete with the turnout at Trump’s often hostile rallies. Still, Klobuchar will face a lot of competition in the Democratic field: New Jersey Sen. Cory Booker, New York Sen. Kirsten Gillibrand, Massachusetts Sen. Elizabeth Warren and California Sen. Kamala Harris have all announced their campaigns in recent weeks.
