Feature 1: (start time: 03:45) Our first guest is Boulder beekeeper Tom Theobald. He talks about the current state of the bee crisis and what, if anything, the EPA is doing to address concerns that systemic pesticides like Clothianidan are properly controlled.
Feature 2: (start time: 12:42) Then National Center for Atmospheric Research scientist Dr. Claudia Tebaldi joins us. Tebaldi, a statistician, specializes in long-term modeling of climate change. We talk to her about the relationship between flood and the warming planet. We also talk about the new Intergovernmental Panel on Climate Change report which she helped lead. She also explains what the ‘fog of prediction is.

Buzz Aldrin’s Vision for Space Exploration (starts at 6:14) Dr. Buzz Aldrin advocates that the United States should not enter a space-race to the moon against the Chinese, or a race to Mars against the Russians, but rather show leadership by cooperating with the major space-faring nations to systematically step across the great void to the Red Planet. This is his personal Unified Space Vision. He is also working toward an independent council, a United Strategic Space Enterprise, that would advise American citizens about the nation’s space policy. USSE experts would draw on a deep knowledge of America’s previous successes and failures to present a unified plan of exploration, science, development, commerce, and security within a national foreign policy context. Buzz shared these visions with How On Earth’s Jim Pullen. Here’s an excerpt from his hour-long discussion with Jim. Stay tuned for the rest of his discussion, in which he shares little-known insights into why Apollo 11, not Apollo 12, was first to land humans on the moon, and never-before-shared honors for Neil Armstrong and Pete Conrad.
The Bees Needs (starts at 16:04) Colorado is home to over nine-hundred species of wild bees. Most of these solitary creatures nest in the ground, but others nest in the hollow stalks of plants, and about one hundred and fifty species nest in holes in wood. How are these bees doing? Are pesticides striking them down, like their honeybee cousins? How will they respond to changes in climate? CU scientists Dr. Alex Rose and Dr. Virginia Scott have embarked on a journey of discovery, and they’ve invited ordinary people to help. It’s the Bees Needs, a citizen-science project. How On Earther Jim Pullen is a part of that citizen-science team, and he invited Virgina and Alex to see what’s happening at the bustling bee block nest outside our studio.

Bees and Pesticides (start at 6:40). Two studies published last week in the journal Science (here and here) make a strong case for beekeepers who worry that a new class of pesticides called “neonicotinoids” hurts honeybees and bumblebees. In recent years, honeybee populations have rapidly declined, in part due to a phenomenon known as Colony Collapse Disorder. Bumblebee populations have been suffering as well. Researchers have proposed many causes for these declines, including pesticides, but it’s been unclear exactly how pesticides cause damage. Both of the new studies looked at the effects of neonicotinoid insecticides, which were introduced in the early 1990s and have now become one of the most widely used crop pesticides in the world. One study, from the United Kingdom, shows that the pesticides reduce a bee’s ability to store enough food and to produce new queens. In a second study, French researchers tied tiny radios to honeybees then exposed them to low levels of the pesticides; a high number of the bees lost their sense of direction and died away from the hive. These two new studies add to concerns raised in January by a Purdue University study, which indicated that neonicotinoids persist, as poisons, in both plants and soil for much longer than thought, increasing the chance of the pesticide to harm bees and other insects. Despite the increasing number of studies calling into question the safety of these pesticides, the EPA has done little to restrict their use. Local beekeeper Tom Theobald talks with How on Earth’s Shelley Schlender that when it comes to honeybees, these are dangerous pesticides. You can hear the extended version of this interview on this website.
Radiometers and Weather (start at 12:50). Predicting the weather is a tough job, and climate change is bringing unseasonal conditions that make it even more difficult to predict. But a monitoring device produced here in Boulder may be able to improve local weather forecasts significnatly. These radiometers work by creating 3-D profiles of the moisture in the air, which is a key element for meteorologists and climate modelers alike. They are now being put to various weather-related uses all over the planet. Stick Ware is the founder and lead scientist of the Boulder-based company, Radiometrics, and he’s here in the studio with us today to give us the scoop on these radiometers.
