President Biden’s climate czar, John Kerry, warned that Russia’s war against Ukraine could distract the world from the climate change crisis and produce "massive emissions" that will negatively impact the globe.

"I'm concerned about Ukraine because of the people of Ukraine and because of the principles that are at risk, in terms of international law and trying to change boundaries of international law by force," Kerry, the U.S. special presidential envoy for climate, said in an interview Monday on BBC Arabic, MEMRI reported Wednesday. "I thought we lived in a world that had said no to that kind of activity. And I hope diplomacy will win."

"But it could have a profound negative impact on the climate obviously. You have a war and obviously you’re going to have massive emissions consequences to the war. But equally importantly, you're going to lose people's focus, you're going to lose certainly big country attention because they will be diverted and I think it could have a damaging impact," he continued. "So, you know, I think hopefully President Putin would realize that in the northern part of his country, they used to live on 66% of the nation that was over frozen land."

"Now it's thawing, and his infrastructure is at risk," he added. "And the people of Russia are at risk. And so I hope President Putin will help us to stay on track with respect to what we need to do for the climate."

Kerry, who has faced criticism for his own impact on climate change, made similar comments Sunday when he told GZERO Media’s Ian Bremmer that a Russian invasion of Ukraine will have a "monumental impact on the ability and willingness of people to do what’s necessary" to curb emissions, and it will be "very tough for the climate agenda, there’s no question about it."

Kerry's made the comments days before Russian forces invaded Ukraine on Thursday by land, air and sea in the largest military attack of one state against another on the European continent since World War II.

The wide-ranging attack on Ukraine on Thursday hit cities and bases with airstrikes or shelling, as civilians piled into trains and cars to flee. Ukraine's government said Russian tanks and troops rolled across the border in a "full-scale war" that could rewrite the geopolitical order.

According to the Ukrainian Defense Ministry, a Ukrainian transport plane was shot down, killing five soldiers. At least 40 Ukrainian military members are believed to have died as Russia continues to invade the country. Those death estimates are expected to rise.

A State Department spokesperson told Fox News Digital in a statement: "Secretary Kerry strongly condemns the unprovoked and unjustified attack by Russian military forces. On Monday prior to the attack, he was asked about the climate implications of a potential future conflict."
