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.

Debate: How Can We Address Global Pollution?

Weather and Climate Ecosystems Air Pollution

Although the United States has cut its emissions of smog-forming pollutants by half over the past few decades, smog levels in the Western United States have increased each year. Now, scientists believe that rising emissions in Asia are causing smog in the United States. Asian emissions have tripled over the past decades and are particularly high in China and India. During the spring, storms lift and carry emissions from Asia to the Western United States, causing fog. Listen to learn more about how emissions levels in different parts of the world are changing and how global climate systems move emissions around the Earth and then debate: How can we address global pollution?

Extreme Heat

Weather and Climate

Our bodies react differently to extreme heat depending on how much humidity is in the air. Heat index is a measure of how hot it feels outside, taking into account both air temperature and relative humidity. As the humidity rises, the heat index rises. In dry heat, our sweat quickly evaporates, which helps lower our internal temperature; but on a humid day, our sweat cannot fully evaporate as the air is already damp, and this prevents us from effectively cooling off. It also raises our risk of heat stroke and even death. To illustrate the science, this podcast considers the case of a man who was lost for three weeks in a remote desert in southern Utah and survived. Listen to hear more about dry versus wet heat and how it affects the human body.

Storing Rain Underground

Weather and Climate Agriculture

California has been in a severe drought since 2014. It’s underground aquifers, which are permeable rocks that can hold groundwater are dry. During recent droughts, farmers pumped groundwater to irrigate their crops, which dropped the water table and drained the aquifers. In the Sierra Nevada Mountains, they are also getting less snow and more rain, which just runs into the ocean. Farmers are now experimenting with water management and ways to store excess water. With some recent heavy rains, rivers all over the state flooded and some farmers flooded their fields, letting the water seep deep into the ground to refill the aquifers. Listen to hear about ways to catch and store rainfall to help farmers.

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.
