Climate Change News

I’ve seen a number of interesting articles regarding climate change in the news lately, so figured I’d just sum them up in a single post.   As always, follow the links for the full stories.

First, the World Bank has issued a report (PDF link) that finds a very high chance of hitting an average warming of 4°C by the end of this century…twice the international ‘goal’ of 2°C.  The report goes into details of why this is bad, but chances are if you’re reading this you already believe it’s bad…what is significant here is that yet another scientific report is showing we’re making too little progress towards combating climate change, and are leaving a pretty messed up world for future generations. (full article at the Washington Post).  It’s also worth noting that while the impacts of a 2°C rise have been studied quite a bit, the same scientific scrutiny has not been applied to a 4°C rise.  They conclude that, “Given that uncertainty remains about the full nature and scale of impacts, there is also no certainty that adaptation to a 4°C world is possible.”  Think about that.

Our neighbors in Canada are feeling a bit better about global warming, as it’s not expected to impact them as negatively (or other northern countries like Russia).  (link)  The warmer temperatures could even have some benefits…more tourism and increased food production, for example.

In Iowa, more than 130 scientists from Iowa colleges and universities have pointed out the obvious…that the bad drought they experienced this year is a predicted effect of global warming, and that we can and should expect more of the same (or worse) in coming years.  (link)  I wonder if this will lead to a mass exodus of people moving from the Midwest to Canada?

In light of the news that the US is on track to be a net exporter of energy by 2020, no longer dependent on foreign oil, the IEA warns that

No more that one-third of proven reserves of fossil fuels can be consumed prior to 2050 if the world is to achieve the 2°C goal.

By pursuing energy independence via increased domestic fossil fuel production, we’re also sealing the fate of future generations.  (link)

Last, but most certainly not least, is that when you look at global average temperature, October 2012 was above average…but what’s most significant is that this was the 332nd consecutive month where the global average temperature has been at or above average.  Remember, there are local variations – some parts of the world may be cooler, some hotter – but globally, the data indicates that this planet is warming up. (link)

I’d like to wrap up this post with advice for how we can stop this, but that’s a real tough one.  I’m convinced that the only solution is to provide people with a clean energy alternative at a lower cost.  More importantly, we need action fast…which means we need a dramatically lower cost, something that makes everyone rush to adopt this new technology.  I’m not aware of any technologies that fit that requirement…and our country lacks the political will to implement change on a national level.  Any ideas?

World CO2 emissions increasing

We’re doing a lousy job of fighting global warming, despite science giving us a pretty good understanding of the impacts continuing along this current path.  Rather than cut emissions, global CO2 emissions in 2011 increased by 2.5% to a new record of 34 billion metric tons, according to Scientific American.  It’s depressing that we can’t solve this problem…but the reality is, people are more worried about themselves than future generations.  Or at least, that’ll be the case until those future generations grow up and realize who’s to blame for the mess they face.

Making fuel from air

A company in England, Air Fuel Synthesis, has demonstrated a method of making a liquid hydrocarbon fuel from nothing more than air.  Well, more specifically, they say the process:

“captures carbon dioxide and water from the air, electrolyzes the water to make hydrogen, and reacts the carbon dioxide and hydrogen together to make hydrocarbon fuels”

Naturally, they believe it is a scalable process but is so far confined to laboratory volumes – they’ve produced five liters since August, which is fantastic but they have a ways to go.  What’s key here, too, is how much energy is consumed in this process, something that so far I can’t find details of.  If powered by solar or wind, though, a process like this could theoretically be nearly carbon neutral, yet still provide fuel to power cars and trucks.  Or, if coupled with a utility-scale solar panel installation, some excess solar energy could be funneled to this process during the day, producing fuel which can power generators during the night when the panels aren’t producing.

Arctic Sea Ice Vanishing

It seems to me that every year or so for the past decade, I’d see a story in the news reporting on the minimum extent of arctic sea ice, comparing it to previous years, etc.  Sometimes it’d be reaching a new minimum, sometimes it’d be the second or third worst on history.  This usually occurs around late September or early October, when arctic sea ice usually hits its minimum for the year.  So, it’s too soon to be hearing doom and gloom about the arctic this year, right, since we’re still in August?

Nope.

As the graph above shows, we probably haven’t reached the 2012 arctic sea ice minimum point yet…but we have already set a new record for minimum sea ice extent in the arctic.  If historic trends prove true, we have another month of so of melting before we reach the actual minimum for this year.  2012 is, unfortunately, providing global evidence of the impact our species is having on this planet through CO2 emissions and global warming.  While the technology exists to halt this slide into oblivion, we so far lack the willpower to do something about it. On the contrary, the Republican party is in outright denial of the issue, and a very large percentage of Americans are blindly following along.

What will it take to convince people that preserving this awesome planet for future generations to enjoy is worth a bit of personal sacrifice?\

More bad news on the climate

More bad news on climate change…a prominent scientist in the UK (Sir Robert Watson) is now saying that the goal of a 2C global temperature rise is ‘largely out of the window’ and that 5C is a more realistic expectation.  This is bad…it’ll affect food and water supplies, not to mention increasing sea levels and population displacement.  This doesn’t have to be our fate…we have the technologies needed to reduce greenhouse gas emissions dramatically, let’s us them!
