Corals in the Great Barrier Reef Struggle to Stay Alive

Climate Change Oceans

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.

U.S. Pulls Out of Paris Climate Agreement

Politics Climate Change

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.

How Snow is Made

Climate Change Weather and Climate

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.

Drought Eases in California

Climate Change Weather and Climate

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.

Pollution from Industrial Revolution Thought to Melt Glaciers

Earth and Space Science Climate Change Human Impacts

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.

Twenty-seven states sued over the proposal. Last week, the U.S. Supreme Court put a hold on the Clean Power Plan by a vote of 5-4. Environmentalists say this ruling threatens progress on global warming. In some states, coal companies and Republican politicians are cheering this decision.

Butterfly Habitat Under Threat

Climate Change Elementary Animals Ecosystems

The population of monarch butterflies has declined dramatically in recent years. The milkweed population has also declined, and less milkweed equals fewer monarch butterflies. Monarchs lay their eggs exclusively on milkweed and it’s the only thing the larvae will eat. Some reasons for the decline in milkweed include loss of forestland in Mexico where monarchs winter and an increased use of herbicide. Regardless of the reasons, these are big changes. Listen to hear more about what is being done to restore the monarch butterfly population and how that also helps other insects.

In Paris, France, 200 countries will gather to create an agreement to limit climate emissions and slow climate change. The goal is to produce a document that all countries, developed and non-developed, agree on. The meeting is a step in the right direction, with 160 countries that have already set targets for emissions. In the United States, politics are involved. Congress wants to roll back the clean emissions bill, and not everyone agrees on how to address climate change. There are some who think immediate events deserve more attention than longer-term issues such as climate change. Listen to hear more about this global Climate Conference.

Coal Mining and Climate Change

Climate Change Weather and Climate Macroeconomics

New government climate change regulations, which aim to limit the demand for coal, are threatening to cause layoffs, bankruptcies and impact the livelihood of many U.S. coal town families. Coal is the number one contributor to climate change and 40% of the coal mined in the United States is on federal land, land belonging to the public. Coal mining companies pay the government to lease this land, as a part of the federal coal program. Debates have sparked hearings this summer in Wyoming, Colorado, Montana, and New Mexico. In Wyoming, where 84% of the coal mined on federal land comes from, coal miners are fighting for their jobs. Listen to different perspectives on coal mining.

NOAA, the National Oceanic and Atmospheric Association, called 2014 the hottest year on record and cited the changing climate as the cause of extreme storms, droughts and floods around the world. Slowing climate change is a top priority of President Obama, who unveiled his Clean Power Plan on August 3rd. The Plan would limit the carbon that power plants can release, cutting emissions by a third over 15 years, as well as boost the use of renewable energy. China and the U.S. are the top contributors of carbon emissions, and Obama wants the U.S. to lead the way and encourage other countries to set limits as well. He faces significant political opposition to the Clean Power Plan, even though two of three Americans support the idea.
