Sky drama

FRISCO —I’ve always been fascinated by clouds in their many shapes, and especially by the way they interact with the Earth and sea. From dripping coastal fogs to towering thunderstorms and ice-filled stratus clouds, it’s always seemed to me that they represent the connection between the sky and the more solid, touchable parts of our biosphere, cycling energy, in the form of heat and water, between the realms.

Staff Report

FRISCO — A $167,000 grant has helped Rocky Mountain National Park boost environmental efforts.

The 2013 grant from the U.S. Department of Energy’s Clean Cities National Parks Initiative supports alternative transportation projects aimed at reducing greenhouse gas emissions and educating park visitors about the environmental benefits of reducing our dependence on petroleum.

Through the partnership, the park purchased two electric sedans and one hybrid pickup truck, installed two electric charging stations, launched an idle reduction campaign and enhanced the parks education and outreach efforts toward reducing greenhouse gas emissions and enhancing sustainable operations.

Colorado: Big flows expected in Blue River

Good news for boaters

Blue River snowpack still growing.

Staff Report

FRISCO — Late-season storms have helped boost snowpack in the Blue River to near last year’s level, promising healthy runoff and flows in Summit County, according to Denver Water.

The effects of the steady barrage of spring storms is already showing up the Lower Blue River, where flows are increasing due to increased releases from Dillon Reservoir, according to Denver Water, which won’t be diverting water through the Roberts Tunnel until mid-July at the earliest.

Climate: Is this the Antarctic tipping point?

Study shows widespread, simultaneous ice shelf melting

Staff Report

FRISCO — Along with studies showing dramatic changes in individual ice shelves in Antarctica, new research shows widespread changes in the region since 2009. Up until then, the Southern Antarctic Peninsula showed no signs of change.

But suddenly, multiple glaciers along a vast coastal expanse, measuring some 750km in length, suddenly started to shed ice into the ocean at a nearly constant rate of 60 cubic kilometers, or about 55 trillion liters of water, each year. This makes the region the second largest contributor to sea level rise in Antarctica and the ice loss shows no sign of waning. Continue reading

Study: No such thing as ‘normal’ weather in Colorado

Extreme storms can happen outside expected times

Staff Report

FRISCO — A new study led by Colorado-based scientists seems to reinforce the old saying that, when it comes to the state’s weather, there’s no such thing as normal.

The research aimed to track seasonal and geographical patterns of extreme weather events, especially the monster storms that create headaches for emergency responders and resources managers. But pinpointing those trends is not easy the weather experts found. Continue reading

Global warming: New NOAA study eyes link between Arctic meltdown and extreme weather in mid-latitudes

FRISCO — There’s been lots of speculation and some early research on a possible link between soaring temperatures in the Arctic and extreme weather in North America and Europe, but the jury is still out, according to scientists with the National Oceanic and Atmospheric Administration.

NOAA’s James Overland was part of an international team that took a close look at possible connections and concluded that more research is needed.

“We are in the pre-consensus stage of a theory that there are links between the rapid warming of the Arctic and some severe weather events since 2007,” said Overland, lead author of the new study, “The melting Arctic and Mid-latitude weather patterns: Are they connected?” Continue reading

Global warming: Risk of exposure to extreme heat waves is growing dramatically

Warm enough!

Population growth in warm zones is a big part of the equation

Staff Report

FRISCO — Extreme heat kills more people than any other type of extreme weather, and that mortality could increase significantly in coming decades as the Earth warms under a blanket of heat-trapping greenhouse gases.

Americans’ exposure to extreme heat could increase  four- to six-fold by 2050, a new study concludes, explaining that it’s not just the heat — the country’s population is  growing especially fast in the hottest regions of the country. Continue reading
