Global warming is carving measurable changes into Alaska, and President Barack Obama is about to see it. President Obama leaves Monday, Aug. 31, 2015 for a three-day visit to the 49th state in which he will speak at a State Department climate change conference and become the first president to visit the Alaska Arctic. There and even in the sub-Arctic part of the state, he will see the damage caused by warming, damage that has been evident to scientists for years.

Global warming is carving measurable changes into Alaska, and President Barack Obama is about to see it.

Obama leaves Monday for a three-day visit to the 49th state in which he will speak at a State Department climate change conference and become the first president to visit the Alaska Arctic. There, and in the sub-Arctic part of the state, he will see the damage caused by warming .

Studies show that more than 3.5 trillion tons of water have melted off of Alaska's glaciers since 1959, when Alaska first became a state.

In the first 10 years of statehood, Alaska averaged barely a quarter million acres of wildfires yearly. The last 10 years have averaged 1.2 million acres.
