Hurricane Sandy, or as it was dubbed by the ever-sensationalist media world, “Superstorm Sandy,” was a storm that raged across the Caribbean and a large portion of the northeastern United States between October 22nd and October 31st. At its peak Sandy was classified as a Category 2 hurricane, meaning that it was on the lesser side of terrifying (easy to say for someone like me who followed the coverage of it from across the ocean safely in my Prague dorm room), but still incredibly dangerous and destructive. It is estimated that Sandy caused over $75 billion in damages and killed 253 people in total from seven different countries. Perhaps the most lasting image Americans took from the storm was the dramatic flooding of New York City’s subway systems. Several US states declared states of emergency in preparation for the storm, and as a result the human loss was thankfully curtailed from what it could have been.

The real question that continues to be asked as the world is plagued with the striking blows of hurricane after hurricane in an incredibly varied range of places has become this: How much is human initiated global warming affecting the strength and frequency of these big storms? I won’t leave you in suspense. The answer from scientists appears to be overwhelmingly that, yes indeed, global warming has a significant effect on the strength of storms such as Sandy.

One effect of global warming is that the sea level is rising to noticeable levels. This can be linked partially to irregularly melting polar ice caps, the rate of which broke records this past August in Greenland. Penn State climatology scientist Michael Man says that, “…sea levels are 1 foot (30 centimeters) higher than they were a century ago,” which gave Sandy an added boost that aided its record breaking 13.2 foot storm surge that hit New York. Another effect of global warming that helps fuel hurricanes and tropical storms such as Sandy is the rising sea surface temperatures. Higher sea surface temperatures means there is more vapor in the air for storms to suck up in their development, which is then poured down on affected areas as torrential rain.

Scientists have formulated for years that a high pressure system over the North Atlantic region has “pushed” storms such as hurricane Sandy out to the Atlantic Ocean, avoiding landfall in the northeast area of the US on normal occasions. However Sandy obviously wasn’t pushed out to sea, and turned directly into the continent, puzzling scientists. It is a theory of researcher George Stone that global warming may have actually affected the jet stream and pressure system over the northeastern continental US, and if this is true then, “we might attribute a large part of Sandy to climate change…”

While scientists are in almost unanimous consensus that global climate change has a measurable and real effect on hurricanes and other types of severe weather, it is incredibly important to stress that correlation is not causation. Hurricanes would happen with or without human beings on the planet. So to say Hurricane Sandy was “caused” by global warming would be inaccurate. However, to say global warming had no effect on the surprisingly strong storm would be similarly incorrect.

It is no longer a disputed fact among experts that humans are strongly altering the natural course of the planet with our industrial activities. These industries that continue to make life better and more comfortable for people in all different kinds of societies. However these advances are also drastically harming the only Earth that we have to make our livings on. Rampant CO2 emissions, waste disposal (or lack thereof), water pollution, and chemical tainting of natural resources that we are also rapidly using up are some of the many threats facing our planet today. Germany has emerged in the past couple decades as both a leader and innovator in usage of green technology and implementation of green energy policies.

A look at how Germany has been implementing green energy policies in a serious widespread fashion takes us back to 2000, which marks the finalization of a system of government issued mandates known as “feed-in tariffs” under the Renewable Energy Sources Act. These tariffs are a sort of contract between the government and those who choose to develop and utilize renewable energy methods to generate electricity. Individuals, corporations, farmers, private investors (basically anyone willing) can enter into a tariff agreement. The investor is given a promise that the government will reimburse them a certain amount based on the amount of energy they produce from renewable energy sources. A tariff contract will be guaranteed usually for about 20 years. This system is a useful one for green energy advancement because it places an incentive for everyday people to invest in these technologies rather than leaving them at the whim of a politician or political party (as in the US).

These tariffs have been seemingly effective thus far. The amount of electricity generated from 2000 to 2006 by means of renewable energy sources nearly doubled from 6.3% to 12%. It is estimated that up to 100 million tons of CO2 emissions in total (including electricity generating, heating, and fuel used for transportation) were avoided in 2006 as a direct result of the Renewable Energy Sources Act. Germans are actually investing in the technologies too, an estimated 9 billion Euros were invested in 2006 according to the World Watch Institute. These figures show great promise for the green policy of Germany, and since the Act is based on the voluntary investment of individuals and corporations, the country hopes to raise the percent of energy generated from renewable technologies to 45% by 2030. They have already surpassed their goal of 12.5% for 2010. The wildest ambition is to make their system run on 100% renewable energy by 2050.

However reviews for Germany’s green policies are not positive across the board. Complaints over waste disposal efficiency (only 36% of recycled plastic waste is actually required to be recycled, the remaining is usually incinerated), water limitations, and energy efficient lighting and domestic insulation show that there is no easy way to completely overhaul a country into a perfectly green place. The tariff system has also failed solar energy companies. Solon, a solar energy company in Germany, filed for bankruptcy in 2011 due to an inability to pay back the 275 million Euros in loans it needed to take as part of the feed-in tariff system. Part of the mandate includes forcing companies to pay a much higher price on renewable energy sources than commercial value.

Overall, Germany serves as a wonderful example for how to implement certain aspects of environmentally friendly policies. A system that encourages the individual to care about investing in green energy is a system that will see advances in the industry much faster than a system such as we have in the United States. While some politicians are actually still debating with one another whether or not global warming is a real thing, the US is becoming further and further indebted to fossil fuels while almost completely ignoring the potential of cleaner energies such as wind and solar. However to say that Germany is an example to follow step by step would be foolhardy. Some of the policies in Germany have put great strain on green energy businesses and on the individual, some policies are downright hypocritical when it comes to being eco-friendly (such as a mandate on energy efficient light bulbs that not only utilize dangerous mercury to operate, but ultimately wind up in a landfill as hazardous waste when they are disposed of).

One thing that is absolutely certain however of Germany’s attempts at going green is that they are legitimate attempts to decelerate our impact on the planet. The Germans recognize the harm that is being done and are at least trying to remedy the issue, rather than pushing it to the back of the desk and tabling it as is the current state of the US green energy policy. People can wait as long as they want to start caring about the environment, but the planet won’t wait to show us in dramatic fashion the errors of our ways.
