Confused about climate change? Well, The U.S. Geological Survey is taking on the task and answering your questions with their 鈥楥limate Connections鈥� video series.
All across the country, USGS scientists are fanning out to Recently scientists traveled to the in Denver to find out what Denverites had on their minds.

Questions from the Mall included:
How is Colorado affected by climate change?
If you live in Colorado, you most likely love to ski (or know someone who does.) Racking up days on the slopes is a winter pastime here in the Rocky Mountains. However, Darius Semmens a USGS research physical scientist says due to warming temperatures across the state our ski season will get shorter, and 鈥榣ess epic.鈥�
According to Climate Central, an independent organization of scientists and journalists, Colorado has seen a rapid rise in temperature from .
While the past few weeks have brought feet of snow to Colorado鈥檚 high country, drought conditions still remain. That鈥檚 causing serious consequences for the state鈥檚 .
Those warmer temperatures could be caused by ozone and pollution. To study the interaction of ozone on thunderstorms, scientists from Boulder鈥檚 National Center for Atmospheric Research into stormy skies. Their goal was to measure the effects of climate change on thunderstorms over Colorado.
The Deep Convective Clouds and Chemistry experiment explored the influence thunderstorms have on air just beneath the stratosphere. Scientists believe pollutants sucked up in strong storms travel many miles into the Earth鈥檚 atmosphere contributing to global warming. Their research is aiding the development of more effective policies to reduce ground pollution that create ozone.
Were the wildfires this past summer related to climate change?
Debra Martin a USGS research scientist says it鈥檚 highly likely that increase temperatures have led to the increase in wildfires, along with other reasons. In some areas of the Rocky Mountains, the fire season is almost two months longer than it used to be. That鈥檚 not good for residents in Colorado鈥檚 red zones. According to an, one of every four Colorado homes is in a red zone - or areas most at risk for dangerous wildfires.
The High Park fire severely damaged earth and ground cover across Larimer County, and that鈥檚 increased fears of and .
Last year鈥檚 fires and continuing drought have also hurt the state鈥檚 rafting industry. The industry trade group Colorado River Outfitters Association found that rafting trips decreased last year by .
Do the bark beetles infesting trees have anything to do with climate change?
Jenny Briggs research ecologist with the USGS says the change in climate also has something to do with the Bark Beetle infestation that has devastated western states.
Warmer and drier climate patterns decrease the ability for trees to produce sap that helps in fighting back bark beetle attacks. In all, more than three million acres of Colorado Forests, including have been impacted since the first signs of an outbreak in 1996.
Park officials says their primary line of attack against the bark beetle is insecticides. But with such widespread damage, park rangers are only able to focus on 5 percent of the park鈥檚 trees, or what officials call 鈥榟igh value trees鈥� 鈥搕hose that provide shade, or are part of the cultural of historical landscape.
An annual aerial survey of shows while the mountain pine beetle epidemic is slowing dramatically, the spruce beetle outbreak is expanding.
Scientists attribute that growing epidemic to recent droughts and warmer winters.
How does the ocean change the climate, and vice versa?
USGS Research Ecologist Robert Stallard says oceans have a big role in controlling climate, since they have a large capacity to hold and release heat and moisture into the atmosphere. He says the Earth鈥檚 seas absorb one quarter of the carbon dioxide that鈥檚 released into the atmosphere by humans. And that climate change is affecting fishing across the globe as well as the .
Oyster farmers began noticing problems in the mid-2000s when their larvae population started dying. The reason? An increase in ocean acidification.
To deal with the environmental changes, oyster farmers developed a monitoring system regulating the amount of acidic seawater allowed into hatcheries. But it doesn鈥檛 look like the situation will improve in the near future. Scientists say acidified water being drudged up by ocean currents right now contains carbon dioxide gas from over 50 years ago. The prediction is the problem will only get bigger, with no viable solution on the horizon.
