Global warming, anyone? Get more AC?

If you live in a city, the 2.7-degree change expected globally in the next decade or so will actually be 7.2 degrees in cities. Why? Because cities are heat traps and, to make matters worse, air conditioning (AC) removes heat from inside buildings and dumps it outside.

In Manhattan they measure the city’s temperature in Central Park, often 15 degrees cooler than the canyons downtown at midday in July. Add humidity to that number and you have Madison Avenue temperatures approaching jungle-stifling heat. Let’s not mention the subway system…

Here’s what is frightening people fighting to save a habitable, livable, environment for us all: Currently AC accounts for almost 10% of all electricity generated on the planet. Add to that, AC units use refrigerants that are seriously contributory to global warming, labelled “potent greenhouse gases.”

Look at it this way: As we cool our private spaces and industry, we’re heating the planet further, requiring more cooling — it’s a vicious circle.

Thirty years ago, the Montreal agreement banned CFCs, which were burning holes in the ozone layer (which reflects a lot of the sun’s rays). We instead used hydro-fluoro-carbons (HFCs), which didn’t hurt the ozone as much but, it turns out, retain heat brilliantly, adding to the warm blanket around the Earth.

HFCs are adding to global warming alarmingly — pound for pound they have thousands more capacity to retain heat than CO2.

Suggestion? Replace HFCs with propane. Yes, you read that right, propane would work just fine and, for the average AC or kitchen refrigerator they use about a half-pound of propane (compared to 25 pounds for your barbecue). As long as it didn’t leak (standards need to be set), this would definitely be better for the environment.

How much better? Changing to propane would remove .72 degrees of planet warming over the century. That’s one huge leap for a simple fix. Well, not so simple, as regulations and safety technology would have to be mandated, and that takes politics…

Sophie Geoghegan, climate campaigner at the Environmental Investigation Agency, has been plotting the increase in demand for AC use worldwide and says we’re on track to triple units installed by 2050 or 5,600,000,000 AC units worldwide. That’s almost one per person. Ten new AC units are being sold every second… and if the whole world buys one, along with industry and car manufacturers, you are talking about at least 14,000,000,000 units in operation worldwide by 2050.

That’s unsustainable, for the refrigerants as well as the cost (energy) for making the units.  However, by 2030 the energy efficiency of the new units using gasses like propane would save the CO2 emissions of 5.6 gigatons of CO2, which is the equivalent of 1,400 coal fired power plants being shut down.

Clearly the issue of global warming is much more complex and threatening that simply saying, “So what if it gets a degree hotter, I’ll just buy AC units.”

Rural towns plagued by slow EMS response times

Ambulance response times to life-threatening emergencies in parts of northeastern Dutchess County were among the slowest in the county last year, according to newly released county data. Region 5, which includes Amenia, Dover, North East and the Village of Millerton, ranked last among the county’s seven EMS regions for the percentage of life-threatening calls reached within nine minutes — a benchmark widely used to measure acceptable response times.

The poor ranking comes even after Dutchess County spent roughly $4 million over two years on a supplemental emergency medical service program intended to improve coverage and response times.

MILLBROOK — The Trevor-Lovejoy Zoo hosted its sixth annual Maple Syrup Madness Weekend on March 7 and 8, drawing visitors eager to sample fresh maple syrup, learn about the sugaring process and enjoy one of the region’s sweetest seasonal activities. The event will continue March 14 and 15, as long as the sap continues to flow, organizers said.

Visitors were treated to free tastings of locally made maple syrup with a side of waffles, while Alan Tousignant — a woodworker, syrup maker and director of the Trevor-Lovejoy Zoo — led demonstrations showing how sap collected from nearby maple trees is transformed into syrup.

MILLERTON — News of a stolen stroller swept through Millerton last week after a grassroots effort to recover the expensive baby equipment gained traction on Main Street and social media.

The stroller, an UPPAbaby Vista model — widely considered a high-end brand and valued at more than $1,000 — was taken from outside Relief Chiropractic and Wellness on the corner of Main Street and South Center Street before it was anonymously returned the following day.

MILLERTON — Library officials expect the NorthEast-Millerton Library to be fully open the weekend of March 14-15, a full month after a burst pipe forced librarians to move operations to the annex building on Century Boulevard.

Executive Director Rhiannon Leo-Jameson said the temporary relocation has been stressful, but library patrons have been understanding and using the library to the fullest extent possible.
