Scarred by destructive wildfires and an arid March, Colorado needs a cold, wet shot of moisture. State water managers are begging for it. They are already eyeing dwindling snowpacks and wondering whether water restrictions should be clamped on the state’s towns and cities as warm temperatures persist. “This always makes us nervous,” said Aurora Water spokesman Greg Baker.
Many reservoir levels are actually in better shape than they were in 2002 — Colorado’s last significant drought year, Baker said. But Baker said he worries that a hot, dry 2012 would drain reservoirs and other water sources so much that not much could be left for 2013.
“It’s really next year we are concerned about,” he said. “We need the water — every little bit helps.”
Denver Water gets about half of its supply from the Colorado River and half from the South Platte River, and snowpack levels in both basins are very low. According to the Natural Resources Conservation Service, both basins are at about half their typical averages for this time of year.
Back in August, when General Motors began rolling out its tiny $14,000 Chevy Sonic from its retooled factory in Lake Orion, Mich., analysts were nervous.
The conventional wisdom was that no automaker could make money building a subcompact car in the United States. Toyota couldn’t do it. Honda couldn’t do it. True, GM had struck a deal with its union, the United Auto Workers, to reduce labor costs at the plant by paying 40 percent of the workers an “entry level” wage. And the ultra-light car, which gets 40 miles per gallon, was one of GM’s most innovative. But history was not in its favor.
Half a year later, GM’s gamble on the Sonic — part of the company’s push to develop smaller, more fuel-efficient cars — appears to be paying off. Sales of the Sonic have risen steadily in every month, reaching 8,251 units last month. And on Tuesday, the automaker announced a whopping 12 percent rise in overall vehicle sales for March over the previous year. Nearly half of that increase, the company said, was driven by demand for smaller cars and crossover vehicles that get better than 30 miles per gallon.
In the Book of Revelation, Christian believers are promised, along with the return of Christ, a new heaven and a new earth,
But Christian climatologist Katharine Hayhoe said in an interview Tuesday that until the promise is fulfilled believers in the here and now aren’t excused from tending the planetary garden granted them.
“It may happen any day, but we don’t know when it is,” she said on the topic of Christ’s expected return. So in the meantime?
“Make wise choices,” said Hayhoe. The associate professor of atmospheric sciences at Texas Tech University spoke to Hardin-Simmons University students and others Tuesday on climate change and her role as director of the Climate Science Center at Tech.
Energy security and climate change present massive threats to global security, military planners say, with connections and consequences spanning the world.
Some scientists have linked the Arab Spring uprisings to high food prices caused by the failed Russian wheat crop in 2010, a result of an unparalleled heat wave. The predicted effects of climate change are also expected to hit developing nations particularly hard, raising the importance of supporting humanitarian response efforts and infrastructure improvements.
Here’s a look at several geopolitical hotspots that will likely bear the unpredictable and dangerous consequences of climate change and current energy policies.
Why all the fuss about aviation? Why has Europe passed its own laws to make airlines reduce their CO2 emissions? And why don’t we have international rules for an international sector?
It’s right to ask these questions. The answers are important, too. Since 1997 we have been working to achieve an international agreement in this sector. No one can doubt that this will be the best way forward for this truly international sector.
Despite work and pressure from the EU, states in the International Civil Aviation Organisation (ICAO) have not yet agreed on a global solution to limit aviation emissions. No one has fought harder than the EU to find a global solution – and we are still trying to reach agreement.
But one thing the world did manage to agree on back in 2001 was that emissions trading could be a good thing for international aviation. After another three years of fruitless discussions on an international approach, ICAO concluded in 2004 that the most promising approach would instead be for countries and regions to incorporate aviation into their general CO2 trading systems (where they existed) with the ICAO providing guidance.
The Titanic hit an iceberg off the coast of Newfoundland, but it probably didn’t hit one the size of Manhattan.
As oceans warm and global ambient temperatures rise, glaciers in Greenland and ice sheets in the Antarctic are calving bigger and more numerous icebergs. One the size of Manhattan floated free from Greenland in 2010, as seen in this video.
April 15 marks the 100th anniversary of the sinking of the Titanic, which sank after hitting an iceberg on its maiden voyage in 1912. Ships are less likely to hit an iceberg today than they were then – thanks mostly to radar – but as we move into a season of remembrance with the 3D re-release of the global blockbuster film “Titanic” and a number of other commemorative events, it’s important to realize that climate change has made the problem of icebergs clogging sea lanes worse, not better.
