This is what Global Warming looks like

“This is what global warming looks like at the regional or personal level,” said Jonathan Overpeck, professor of geosciences and atmospheric sciences at the University of Arizona. “The extra heat increases the odds of worse heat waves, droughts, storms and wildfire. This is certainly what I and many other climate scientists have been warning about.”

Horrendous wildfires. Oppressive heat waves. Devastating droughts. Flooding from giant deluges. And a powerful freak wind storm called a derecho.

These are the kinds of extremes experts have predicted will come with climate change, although it’s far too early to say that is the cause. Nor will they say global warming is the reason 3,215 daily high temperature records were set in the month of June.

Scientifically linking individual weather events to climate change takes intensive study, complicated mathematics, computer models and lots of time. Sometimes it isn’t caused by global warming. Weather is always variable; freak things happen.

Latest United Nations conference on sustainability takes a new approach – action not treaties

Government leaders, bankers and corporate CEOs took advantage of the gathering of 50,000 people at Rio+20 — the largest meeting in U.N. history — to announce new partnerships, programs and investments.

U.N. Secretary-General Ban Ki-moon called the $513 billion in commitments “a significant legacy of this conference — billions of dollars’ worth of actions and investments that will have the power to transform lives across the globe.”

To some of those present, the conference presented a new model, a global gathering to inspire government and corporate leaders and others to move ahead and build momentum — rather than waiting for world leaders to reach consensus on a treaty to address climate change or other environmental matters.

“We cannot be boxed in by the orthodoxies of the past,” Secretary of State Hillary Rodham Clinton said in a speech to delegates of more than 190 nations. “We need fresh, agile, action-oriented partnerships that can produce results year after year after year.”

La Niña leaves on Thursday – El Niño could be coming

Changes are brewing in the equatorial Pacific, and they could profoundly affect weather across the U.S. and much of the globe next winter and spring.

La Nina, which has held sway since last fall, will be officially declared a goner Thursday, an official at the Climate Prediction Center in Maryland told InsideClimate News. And while nobody is quite certain what will happen next, some long-range forecast models are pointing to the possible emergence of the opposite phenomenon: El Nino.

Climate scientists are still trying to determine what role climate change plays in the La Nina/El Nino cycle. One study by scientists with NASA and the Pacific Marine Environmental Laboratory in Seattle suggests global warming may already be affecting the intensity and impacts of El Nino.

Regardless of climate change’s role, a shift away from this year’s La Nina could dramatically alter temperature, precipitation and extreme-weather patterns.

Climate Change in California means heats waves…lots of them

In the past 60 years, California has experienced two heatwaves – in 1955 and 2006 – in which temperatures in its urban centers were greater than 37.8 degrees C (100 degrees F) for three or more consecutive days.

A new analysis prepared by other Scripps researchers indicates that by century’s end, those kinds of heatwaves will be the norm. Scripps climate researcher David Pierce said the new data will be assimilated into a major climate report scheduled for release in 2013.

“We’ll start getting these kinds of heatwaves more frequently by 2020 and by 2070, they’ll become common,” Pierce said.

…in all scenarios, not only do episodes of 100-degree-plus temperatures happen more frequently (several times a decade), but events in which temperatures top 100 for seven or more days begin happening at least once a decade by 2060 in all the models.

Largest ever growth in carbon emissions and some unscientific reporting

The global output of heat-trapping carbon dioxide jumped by the biggest amount on record, the U.S. Department of Energy calculated, a sign of how feeble the world’s efforts are at slowing man-made global warming.

The world pumped about 564 million more tons (512 million metric tons) of carbon into the air in 2010 than it did in 2009. That’s an increase of 6 percent. That amount of extra pollution eclipses the individual emissions of all but three countries — China, the United States and India, the world’s top producers of greenhouse gases.

Source: Associated Press on Google News

A classic case of unscientific reporting. Counting carbon emission by country doesn’t represent an accurate picture. Comparing the states of the U.S. and to the single country of Germany is wrong.

A little research on the site that created the map above shows that Europe combined has over 1,500 million metric tons, with Western Europe producing 700+. Add in Germany and you’re at over 900 million metric tons.

India doesn’t seem so bad now at 564.

Further, if you start comparing land mass or GDP the story changes even more. For example, here are the countries by land mass:

  • Japan – 820.2 (metric tons/sq km)
  • Germany - 582.6
  • China – 233.2
  • India – 171.6
  • US - 152.4
Of course, the important story here is the rapid growth in emissions, but it’s also important to get our facts straight. Education will play just as big a role as technological advances in solving this global crisis. It’s time to move the discussion forward to a more mature understanding of the situation.

Are cars causing Global Warming?

I often hear folks complain about cars and the pollution they cause. This seemed a little off so I did some investigating.

Out of all the ways to go green, including reducing energy use, buying green products, and driving less…

 

Which one is the best for the environment?

 

The EPA keeps a tally of these things on their Climate Change page and in an Inventory of US Greenhouse Gas Emissions (pdf).

The results are astounding. Cars account for only 17% of all emissions. While 80% comes from home use, business, and food.

 

[box type="shadow"]

2009 US Greenhouse Gas Emissions

  • Business — 35.6%
  • Electricity — 33%
  • Personal vehicles — 17.8%
  • Agriculture — 7%
  • Residential — 5%
  • US territories — 1%

* Business = factories, business vehicles, office buildings
** Residential = gas heating
*** Includes CO2 and all other gasses

To put it another way. If you buy a recycled product or reduce your energy use, that has 2x greater impact than driving less does.

This means things like hang drying your clothes, buying recycled toilet paper, reusing floss, and turning off the A/C, are much more important than biking to work.

I know, I know, this just doesn’t seem right.

The numbers don’t lie…so next time you get in the car think, instead, about how you can reduce your energy use or buy a sustainably created product.

 

More on the Numbers

 

If you think about driving, most of the recommendations are for health concerns instead of pollution problems. Things like biking to work and reducing traffic congestion. Or, it is about geopolitics and our reliance on other countries for oil.

The thing is, most of the car industry is green and even innovative. There are smog checks, 40 mpg cars, engine filters galore, a huge used car industries (i.e. reuse), and awesome junkyards (recycle).

From the top, where the rich subsidize the innovations like electric cars. To the bottom, where the middle and poor buy used to save money. The entire industry appears to have itself aligned in an environmental way.

Compare that to the energy industry and green product market where that alignment isn’t quite there yet. Buying a used car saves money and helps the entire industry, and it is considered cool/smart. Whereas, buying recycled or hang drying your clothes makes you kind of extreme, and not all locations offer products.

Not to mention the incentives are tiny. The pennies and dimes I save in electricity use make me to question the extra effort. The only thing that keeps me going is “think of the kids”, lol.

This may be a good place for smart government. A good example would be the car industry, where those who drive a lot or purchase low MPG cars pay much more at the pump. They also pay more taxes and if you look at how much tax is loaded into each gallon, it’s a lot.

Perhaps there could be an extra tax on those who use more electricity. Make those who own big houses or a million appliances pay more. Use that money to fund clean energy projects.

I’m seeing this happen in a few regions but not at the scale where it needs to be. I say tax the hell out of wasters and over-users otherwise it makes all my reductions inconsequential.

Plus, it sure would be nice to get rid of these coal and gas power plants…

Earthquakes caused by glaciers melting?

An acquaintance in Facebook recently posed the question:

Does global warming cause earthquakes?

After the Eastern Seaboard experienced a 5.8 magnitude earthquake, it left many wondering, what the hell was that?

Before the recent disruption the largest earthquake on record in central Virginia was a magnitude 4.8 temblor that occurred in 1875.

Earthquakes are rare in the eastern U.S. because the region is farther from a fault line.

Andrew Hynes, a tectonics expert at McGill University, said the issue is not so much the load shift on the earth’s crust, but rather the increased fluid pressure in the fault that lubricates the rock, allowing the plate to slide.

 “All earthquakes except those produced by volcanic activity are essentially the unsticking of faults,” he said. In other words, if you pump fluid into a fault, it will reduce the friction and the rock can slide. (from AccuWeather)

Can the added melt from glaciers create stress on the earth’s upper crust, injecting more fluid into the rocks, thus creating earthquakes? The answer is yes, earthquakes at shalllow depths. Which is exactly what states like VA, MD, NY, and NC experienced.

Metereolists and geologists have long been warning of the consequences of “post glacial rebound” when the melting of glaciers causes an increase in global sea levels.

This increase in sea level means more pressure on the sea floor, which can effect everything from gravity fields to horizontal crustal motion. Of course, the recent earthquake on the East coast brings to mind the threat of shifting tectonic plates.

As the world’s glaciers perform an accelerated disappearing act, earthquakes just may be the first sign of how the warming will change the world.

A Guide to DC’s Environmental Film Festival

Kieran Timberlake: The Loblolly House

I love movies. The only thing better than movies is a film festival full of them. In the last few years I’ve become a regular film festival attendee (see my Sundance Festival Guide).

It was with some surprise then to learn that DC has its very own film festival. A major event that is possibly the best of its kind in the world, the Environmental Film Festival.

It runs from March 15-27 and presents 150 films at 60 venues, with an expected attendance of 26,000 filmgoers.

What makes any festival interesting is the sense of discovery where you find yourself watching a movie you would never otherwise see. And, that film will most likely never again be in your local theater or even on Netflix. They are works of art that while good enough to be selected at film festivals, will never make it into the studio circuit of big budgets, posters, and red carpets.

Being in DC is uniquely special as well since the city produces a huge amount of documentaries. I once heard a friend at the DC Film Institute joke that we are not Hollywood but Docu-wood.

The subject of this year’s festival is Energy, but I noticed several other topics just as interesting: the chesapeake bay, architecture, lectures by professors, nuclear waste, short films, and adventures in cold places.

Where Whales Sing

After looking through the list of films I quickly realized that I want to see them all. With over 60 movies making the first cut as “must-sees”. My festival instincts kicked in as I reminded myself that every movie was chosen because it is worth seeing.

The wise option then is to choose my absolute favorites:

The next step is to plan out my 12 day schedule. This process helped me a bit to narrow down my schedule to just 21 movies. Leaving room for a day job and food but little else.

Here is the full list (with links). I hope a few of these tickle your fancy and you end up attending one or two. Leave a comment about your experiences or if you need someone to go with (because I sure do!).
