Panel Discussions

Session 1 (1:30 – 3:00)
The Science of Climate
Shrinking snowpack, drier soil and warming temperatures. These are among the impacts Utah can expect in coming decades as a result of Earth's changing climate.  So says the Governor's panel of Utah's top-tier researchers, and so say climate researchers around the world. Temperatures are rising; humans are why.
 
But while scientific consensus on the point is broad and deep, confusion among the public remains:
 
  • Doesn't the Earth go through natural cycles?
  • Weren't temperatures higher in the Middle Ages?
  • Don't many scientists disagree?
  • Didn't they predict an ice age back in the '70s?
  • Isn't carbon dioxide good for plants?
  • Isn't Mars warming, too?  So it must be the sun...
  • How can they predict the climate fifty years from now when they can't predict the weather next week?
  • Do scientists really think they've got Earth's complex climate all figured out?
 
A panel of Utah climate experts is eager to discuss your questions about the science of climate.  Come stump the science chumps with questions like the following!
·         What are particles in the atmosphere made up of?
·         How do land use changes influence the climate of Utah?
·         How will natural and human-caused forcing of the stratosphere affect global climate?
·         How does past climate change on the Utah help us understand and predict future climate scenarios?
·         What are the latest methods for reconstructing the history of the Earth's climate?

 

Business and Agriculture 
Business: In addition to being a scientific and an ethical issue, climate change is an important economic issue, given the scale of the costs that it may impose on societies. Moreover, the economic cost of climate change is a major source of uncertainty. Climate change will pose challenges and opportunities for economic sectors and firms.

  • How can changes in travel, or the way communities develop, reduce climate change?
  • Can land use policies reduce automobile dependence and thus greenhouse gas emissions?
  • What can governments and citizens do to reduce greenhouse gas emissions?
  • Why do people travel so much, and how we can reduce travel and greenhouse gas emissions?
  • What should be the optimal timing of investment in climate change control policies and what are the economic costs of no action or delayed action?
  • What should be the optimal level and time profile of carbon taxes and carbon permits to control climate change, taking into account the dynamics of global carbon cycle?

 

Agriculture: One of the major causes of global warming is an increase in CO2. Some scientists think this will help plants. One of the things that will help plants is the weather will be warmer, making a longer growing season. If the plants have a longer growing season they will produce more fruit. Another thing is that more precipitation is anticipated. If there is an increase in precipitation, the plants will have plenty of water. Plus, plants breathe CO2 like we breathe oxygen. If there is warmer weather, an increase in precipitation, and lots of CO2, the plants will grow better instead of dying during global warming, right?

Some scientists don't think it will help plants. If the temperature increases, and the precipitation increases then the rain will evaporate faster because of the heat. There will also be a dramatic change in weather compared to the weather of today. There will be periods of drought followed by periods of dramatic storms. A drought might occur when the plants have just sprouted up from the ground. They won't be able to survive the drought. The same thing will happen with storms. What if some wheat just got some nice full heads and a storm occurs? The storm will break the heads off and ruin the wheat. Another problem with drought and storms is that right after a drought the plants would be very weak. So when the storms come they will wash the plants away. Along with the storms there will be floods. The floods will wash the topsoil off of the fields into nearby creeks and rivers. The farmers won't have any topsoil to grow their plants on and the state will have to spend a lot of money to dredge the topsoil from the creeks and rivers.

So, what is your opinion of global warming's effect on agriculture? Do you think it will help or hurt? Destroy or create? Moreover,
  • How will climate change affect land use and biodiversity in Utah’s agricultural landscapes?
  • Will climate change increase the need for irrigation in Utah?
  • Can Utah offset greenhouse gas emissions through increasing carbon dioxide absorption by perennial crops?
  • How will agriculture be a source and a sink for greenhouse gases under a changing climate?
  • How is projected climate change in Utah and internationally likely to affect economic prospects for Utah’s agriculture?
  • What is sustainable agriculture and how is sustainable agriculture research and education adapting to climate change?
  • What is the impact of climate change on insects and does this have implications for agriculture and food supply?

 

Ethics and Stewardship

Ethical behavior is the process of balancing pursuit of one's own needs and desires with those of other people's. Our consumption of fossil fuels is altering the climate in ways that will be disastrous for millions of people around the world, not only in today's generations, but in our children's, grand children's, and subsequent ones: reduced food production, flooding of occupied coastal areas and island nations, spread of diseases. For many religions, the earth is God's creation, and we have a moral obligation to take care of it. An interfaith panel will address this issue in the afternoon.
  • Is the interesting ethical question why we don’t seem to care?
  • Why aren’t we motivated to consider the long-term harmful consequences of global warming?
  • Why aren’t we taking the rights and interests of future generations seriously?
  • Why aren’t we obeying God’s mandates to care for creation?
  • Whyaren’t we even doing that which is in our best interest to do?

 

Session 2 (3:30 – 5:00)

Energy and Water
Water: Warmer air dries the soil. Shrinking snowpacks struggle to fill aquifers as runoff is absorbed by dry soils. Changing precipitation patterns impact water storage strategies. Utah's changing climate portends profound implications for our water supply, with risks to agriculture, municipal supplies, and wildlife.  How can these risks be mitigated?
 
  • What will changing water supplies mean for my day to day life?
  • What simple measures can help to conserve water?
  • Will water recycling and reuse have a role in Utah’s future?
  • What about gray water use in the home?
  • What can we learn from other parts of the world about living with reduced water supplies?
  • How will agricultural, municipal, and ecological water interests compete for a shrinking water resource?
  • How will climate change affect water resources in the arid western U.S., and how can these effects be managed or mitigated?

 

Energy: In the decades ahead, where will the energy that powers Cache Valley be produced, how much will it cost, and how reliable will it be? Pacificorp, Utah's largest energy supplier has recently stated it will not pursue further coal projects in the state.  Meanwhile, geothermal power is being developed just across the Wellsvilles. Utah's energy landscape is changing.  Serious concerns over air quality, diminishing fossil fuel supplies and risks to climate suggest that the next fifty years of energy will not resemble the last fifty.  We face many questions; as a community, we must begin to address them today:

 
·         Will nuclear power play a role?
·         Is solar power cost effective?
·         How promising is geothermal?
·         Will I be forced to sit in the cold and dark?
·         Is it possible that renewables are more affordable than we think? 
·         Are cleaner energy sources the right first response?
·         What USU research focuses on wind power and what fuels the interest and rapid growth in this energy source?

 

Health and Air Quality
There is a close link between local climate and the occurrence or severity of some diseases and other threats to human health. Extreme temperatures can directly cause the loss of life. Moreover, several serious diseases appear only in warm areas. Finally, warm temperatures can increase air and water pollution, which in turn harm human health. The most direct effect of climate change would be the impacts of hotter temperatures themselves. Extremely hot temperatures increase the number of people who die on a given day for many reasons: People with heart problems are vulnerable because their cardiovascular system must work harder to keep the body cool during hot weather. Heat exhaustion and some respiratory problems increase. Higher air temperatures also increase the concentration of ozone at ground level. In the lower atmosphere, ozone is a harmful pollutant.  Ozone damages lung tissue, and causes particular problems for people with asthma and other lung diseases. Even modest exposure to ozone can cause healthy individuals to experience chest pains, nausea, and pulmonary congestion. In much of the US, a warming of four degrees (F) could increase ozone concentrations by about 5 percent.

  • Will climate change impact how frequently the air is polluted in Utah?
  • How do land use changes influence the climate of Utah?
  • What are the air quality and climate effects of trans-Pacific pollution transport?
  • How does the forest canopy absorb carbon dioxide from the atmosphere and release cool moisture back into it?
  • How does climate change affect the long-term measurement of air pollution and visibility in Cache valley?

 

Wildlife and Outdoor Recreation
Plants and animals of the world are adapted to the environments in which they occur. Climate change will inevitably affect them either directly through their physiologies, and/or by changing the predators, competitors, food-and-habitat providers with which they interact. Ecologists are predicting widespread extinctions of species, but some may be benefited.  Deer and elk, which are forced to move to foothill ranges for food in winter when snowpacks cover high-elevation vegetation, will be able to occupy entire mountain ranges when snowpacks shrink or disappear.  Snowpack disappearances will also reduce opportunities for winter recreation like downhill skiing, snowmobiling, cross-country skiing, and snowshoeing.  An afternoon panel of wildlife scientists and winter-recreation specialists will discuss this topic.

  • What is the basis for predictions of extinction due to climate change, and how can the diversity of earth be managed to avoid the catastrophic levels of extinction that have been forecasted?
  • How will Utah’s native animal and fish population respond to climate changes?
  • Has climate change been observed in the Great Salt Lake and does it affect the clarity of the lake and the local ecology?
  • Will global warming threaten winter recreation?
  • Will the winter season become shorter?
  • Will winters become more intense?
  • Will there be a significant decrease in snowpack in Utah?
