Permafrost is frozen soil that has preserved things such as ancient animal bones and centuries-old icebergs. Permafrost contains twice as much carbon as is currently in Earth's atmosphere and it also preserves old bacteria. When it's defrosted the bacteria eats dead plants and animals turning their carbon into gases such as carbon dioxide. As the permafrost warms, the microbes are releasing gases contributing to further warming. Listen to learn more about this warming cycle.

Earth’s largest living organism, the Great Barrier Reef, has had record losses of coral in the last few years. A team of scientists estimate that an average of one-third of the corals along the entire Great Barrier Reef died between March and November of 2016. The global rise in greenhouse gas emissions has made ocean temperatures rise and has contributed to the number of coral that is dying, which is devastating for thousands of species that depend on the reef. Listen to hear more details about the loss of coral and the causes.

President Donald Trump pulled the United States out of the Paris Climate Accord. The accord is an international agreement signed by more than 190 countries who have agreed to address climate change by trying to keep global temperature rise this century below 2 degrees. Trump says that the Paris Agreement would have been bad for U.S. workers and their businesses. The U.S. produces the second highest greenhouse gas emissions and is only topped by China, who remains committed to the agreement. Listen to learn more why Trump decided to leave the agreement and what it might mean for the future.
The phrase “no two snowflakes are alike” is actually scientifically accurate. Snow forms high in the atmosphere, and despite its uniform appearance, each snowflake is different based upon where and how it was formed. Although snowflakes are non-living, they grow and change from the time they are formed to the time they reach the ground. Listen to learn how snow is formed and why it exists in some places but not others.

The severe drought in California resulted in a state-wide mandate of 25% reduction in water use last year. This affects many residents, especially those who make a living in farming and agriculture. The snowpack in the Sierra Nevada mountains feeds water into the state’s reservoirs, which supplies about 30% of the state’s water needs. Last year the snowpack was 5% of average. This year, it’s about 95%. Even though it’s just below average, this is a great improvement. However, most growers remain cautious about whether the drought is really over.

Engineers are trying to design solutions to the local problem, while leaders around the world are fighting against climate change. Listen to hear more about the environmental threats to Block Island.
The glaciers in the European Alps started melting rapidly in the 1860s. But that didn’t correspond with the warming of the European climate at the end of what is known as the Little Ice Age. That warming didn’t occur until the 1910s. To understand the causes of the glacial melt, scientists considered the possible impact of the Industrial Revolution, which began in the 1840s. The recent melting in the Rocky Mountains of America could be caused by the same reasons. Listen to this story to learn about the theory that dust and soot are contributing to how quickly glaciers are melting.
