Solar power will take over soon

By Tor Økland Barstad on March 9th, 2010

The sunlight that hits earth in one hour is enough to cover the worlds energy demand for well over a year.

The surface of the Earth receives an amount of solar energy equivalent to roughly 10 000 times the worlds energy demand. Of course there isn’t always sunlight, but the solar panels can store the energy, and they are getting better and better at it. A solar panel converts one sixth of the sunlight into electrical energy. Although they also are getting able to turn more and more of the sunlight into energy, they are already so efficient that space isn’t much of an issue anymore. The area of solar cells needed to supply a family with electricity is usually much smaller than the roof of their house. And when including the land required for mining and excavation of coal, CPS-plants (power-plants that rely on solar energy) are more space-efficient than power-plants fueled by coal. Solar power is roughly fifty times as space-efficient as growing crops for bio fuels. And that’s just with the technology that currently is commercialized.

Watch: Barack Obama explains basic climate science

By Simon Leufstedt on February 24th, 2010

During a visit to Henderson Nevada, President Obama explained basic climate science for the people who had gathered to listen to him at the town hall.

“First of all, we just got five feet of snow in Washington and so everybody is like — a lot of the people who are opponents of climate change, they say, see, look at that, there’s all this snow on the ground, this doesn’t mean anything. I want to just be clear that the science of climate change doesn’t mean that every place is getting warmer; it means the planet as a whole is getting warmer. But what it may mean is, for example, Vancouver, which is supposed to be getting snow during the Olympics, suddenly is at 55 degrees, and Dallas suddenly is getting seven inches of snow.

The idea is, is that as the planet as a whole gets warmer, you start seeing changing weather patterns, and that creates more violent storm systems, more unpredictable weather. So any single place might end up being warmer; another place might end up being a little bit cooler; there might end up being more precipitation in the air, more monsoons, more hurricanes, more tornadoes, more drought in some places, floods in other places.”

You should also take a moment to read George Monbiot’s article on why Britain’s cold snap does not prove climate science wrong.

Karl Marx and the Metabolic Rift Theory

By Simon Leufstedt on February 19th, 2010

Karl Marx came up with the term “metabolic rift” to explain the crack or rift that capitalism has created between social and natural systems, humans and nature. This rift, he claimed, led to the exploitation of the environment and ecological crisis. Marx argued that we humans are all part of nature and he was also the first one who saw social societies as an organism with a metabolism similar to that of humans. In the Economic and Philosophical Manuscripts from 1844, Marx wrote that:

“Man lives from nature, i.e., nature is his body, and he must maintain a continuing dialogue with it if he is not to die. To say that man’s physical and mental life is linked to nature simply means that nature is linked to itself, for man is a part of nature.”

The general idea is that disruptions, or interruptions, in natural cycles and processes creates an metabolic rift between nature and social systems which leads to a buildup of waste and in the end to the degradation of our environment.

Inequality between rich and poor nations helps fuel a climate of mistrust and sabotages efforts to secure a climate deal

COP15 Climate March

The 15th United Nations Climate Change Conference (COP15) in Copenhagen, which many have said was our last chance to take action against “the greatest threat the world has ever faced”, ended in a failure.

For over 15 years delegates and politicians from around the world have discussed, debated and negotiated the questions of dealing with manmade climate change in various COP (Conference of the Parties) summits. So why haven’t they made any real progress yet?

That is a big question that covers a whole range of topics and issues that I won’t go into. Instead I will try to focus on the actual politics and tactics used at the COP summits. I will try to see if uneven development and inequality plays any part in how the actual negotiations plays out, how the delegates attending perceive climate justice and fairness, and if all this combined somehow sabotages the efforts to secure a climate deal.

Vancouver 2010: The “Green Olympics”?

With only a few days left before the 2010 Olympic Games officially begins, there is a buzz around the streets of Vancouver. Being a resident of the city, I can certainly say it has undergone some radical changes in the past few months. Regardless of whether or not you support the games, it seems everyone has something to say.

Recent talk has surrounded the issue of sustainability. Considering, at the very least, the carbon emissions created by all the flights into the host city (and some residents’ flights out of the city) the Olympics can never be genuinely environmentally-friendly. However, Vancouver 2010 has been promoted as “the greenest Olympics ever” (official website: http://www.vancouver2010.com/sustainability/).

Interestingly, David Suzuki recently awarded Vancouver 2010 a bronze medal for sustainability (full article: http://www.davidsuzuki.org/latestnews/dsfnews02031001.asp). He writes: “achievements of the 2010 Olympics include building energy-efficient venues, using clean-energy sources, relying on public transit during the Games, and offsetting part of the Games’ emissions.” However, several areas were lacking. For example, the David Suzuki Foundation admits that “opportunities to create lasting reductions in transportation emissions in the region have been missed.” In addition, the carbon-offsetting accounted for less than half of the overall emissions.

Climate Racism, Climate Injustice & Copenhagen Greenhouse Gas Reduction Proposals

By Dr Gideon Polya on February 4th, 2010

“What can decent people do to save the Planet from the Australian, EU and US climate criminals?”

The bottom line in the Copenhagen Climate Summit should be (a) equal per capita greenhouse gas emissions for everyone and (b) an additional but equitable penalty for First World countries for their disproportionately huge historical contribution to atmospheric carbon pollution. Anything less is pure and simple climate racism and climate injustice leading to climate genocide. Unfortunately climate criminal First World countries believe that they are much more deserving than others, and are lead by Copenhagen sabotaging, US surrogate, climate criminal Australia which wants a 2020 per capita GHG pollution for itself that would be over 60 times that of Bangladesh.

Informed by “all men are created equal and have an unalienable right to life, liberty and the pursuit of happiness”, Climate Justice demands that “annual per capita GHG emissions” should at the very least be the same for “all men” – at the very least, because European countries have been responsible for about 73% of 1750-2006 historical carbon pollution of the atmosphere since the start of the Industrial Revolution in the 18th century (see Dr James Hansen’s 2008 Open Letter to PM Kevin Rudd of Australia).

Ice, snow, so where’s the global warming?

As winter weather hits us again, many people confuse the current weather (cold) with the long-term direction of the climate (warmer).

Just because it is cold outside right now doesn’t mean that global warming isn’t real. Global warming has to do with the climate, with the long-term trend of the world’s average temperature. The short-term weather has to do with what is happening this week or next in the part of the world where we currently reside. The two are not identical, and colder weather does not contradict the fact that our climate is warming up.

Another reason the two related but not identical issues are confusing is that global climate change is not uniform across the globe. Just because it is colder where you live doesn’t mean it isn’t warmer, relatively, elsewhere. In fact, global warming is taking place much more at the northern latitudes than in the continental U.S.

This is the reason why, even though the U.S. is experiencing more severe winter weather, the Arctic summer ice is covering less and less of the Arctic water, opening the fabled Northern Passage. It is still very cold at the North Pole, but it is relatively warmer. Average temperatures have already increased in the northern latitudes by almost 4 degrees Fahrenheit, much more than at temperate latitudes.

Scratching the surface

By Jonathan Sundqvist on December 17th, 2009

Stavros DimasI was listening to the pressconference that the European Union had the last two days. One would think that by now with all the high level people attending that they would have a clear and effective communication on what they want to achieve here in Copenhagen. More often than not the devil is in the details so one have to take to listen carefully what they really say.

During these two press conferences I found a few interesting contradictions and points worth to notice. The first interesting statement is made by Joe Lionel where he concludes the following:

“The Scientific community is asking for the upper level of 25-40 % for industrialized world. Let’s say that 20 % is definitely not enough, that’s the conclusion what the scientific panel has found. therefore 30 % would even not be enough, that would match half-way what we could then do. It is not a scientific definition but a political assesment.”

Here he completely agrees that neither 20 % of the European target nor their 30 % target is enough. We have to do more to come up to a scientific standard. So the question I ask here is why is a political agenda the driving force if the science is clear? If we are to keep below a 2 degree target we also need progressive action inline with science, not inline with the political assesment made.

The next interesting statement is made by Stavros Dimas where he is commenting the ‘great deed’ of financing CDM.

The “Danish text” makes developing nations furious and Naomi Klein says the deal we really need is not even on the table

Here are some of the biggest and most interesting news today related to the ongoing COP15 climate conference in Copenhagen:

A draft text for a potential final agreement in Copenhagen was leaked today to the Guardian. The “Danish text” has made the developing countries “furious” as the draft agreement would give even more powers to the rich nations, weakening UN’s future role as well as abandon the Kyoto protocol. Some say this shows the true agenda in Copenhagen, others believe the draft is unofficial and may have changed a lot since its first creation.

The Environmental Protection Agency in the USA has declared that carbon dioxide is a public danger. This would make it possible for Barack Obama to impose his proposed emissions cuts without an agreement in the sceptic U.S. Senate. A report released today by the Center for Biological Diversity claims that Obama now has the clear legal authority to make a binding commitment for greenhouse gas reductions in Copenhagen without waiting for Congress.

Danish COP15 host Connie Hedegaard appointed EU Commissioner for the Climate

By Benno Hansen on December 5th, 2009

Connie HedegaardNow, this is the Google Search of the Day! 49 years old Connie Hedegaard, member of the Danish Conservative People’s Party and minister for Climate and Energy has been appointed European Commissioner for the Climate.

The EU didn’t have a commissioner of the climate before. According to Barroso her job will be to retain the leadership role of Europe in global efforts to reign in greenhouse gas emissions that cause global warming. It will include the tasks and responsibilities of the former Commissioner for the Environment.

Her Google quote of the day is noteworthy too:

“Governments from all over the world are delivering before the climate conference. US and China have come forward. All across the globe, things are moving. This is good news”

Good luck, Connie.
