Where is the greenhouse effect?

Events: 

In Norway and most of Europe we have record low temperatures and the press picks up on the theme of many lunch discussions - what happened to the global warming? Is it just fiction that big global enterprises push on us to make huge profits from their products and services?

My personal comments are as follows: 

• Energy crisis: We are running out of fossil fuels and do not have enough alternative energy sources to meet the needs of current developed countries and the increased demand of China, India and other developing countries. I have found David MacKay's book "Sustainable Energy - without the hot air" very interesting because it quantifies the demand and how much alternative energy we can get from windmills etc. http://www.withouthotair.com/ 

• As a result of the above mentioned, unsustainable, route we are on - we do have to change. Even if you don't believe in global warming or the claim that it is largely "man made" (greenhouse gas emissions) - we will have to change the way we use energy. 1) Reduce the demand for energy (JAHUS projects, cars and airplanes that use less fuel etc.) and increase the use of sustainable energy sources such as windmills, waves, solar and hydroelectric power.   
• We can't be 100% sure, but I believe that we can't rule out the possibility of a connection between CO2 and global warming (even with the current cold weather in the northern hemisphere). We therefore cannot take a chance of staying on the current course and do nothing - because it will be to late when our children and grandchildren wake up to irreversible and dramatic climate changes.  

Progress:  Yesterday, they isolated the piping that takes the cold exhaust air from the aggregate to the exit point (upper right corner of the picture). This should result in slightly higher room temperature in this room (only +9C yesterday) and I hoped that it would help us get rid of the ice/condensation problem on the pipes.

The pictures below show that with the current outside temperature of -21C (and the exhaust temperature is at -11C), there is ice building on the aggregate itself (where there is tiny small leakages from the interior) and actually on the outside of the isolation. 

They also replaced the regulator that is connected to the fan. The disappointment, however, was that it makes just as much noise when it is set on the lowest effect possible. We therefore have to turn it off at night until they have fixed the noise problem (fan and the heatpump outside).
