Ever wonder why the Arctic ice cap is melting?

Arctic CO2 = 390 ppm x 1 GWP = 390 PPM (CO2e)

Arctic CH4 = 1.9 ppm x 115 GWP = 219 PPM (CO2e)
http://www.esrl.noaa.gov/gmd/webdata...face_03397.pdf

Arctic CO2e = 390 (CO2) + 219 (CH4) = 609 PPM (CO2e) without adding any of the other GHG's CO2e.


Back in 1950's the average ppm of CO2 was around 90 ppm...

Yeah, the global warming. I lived in the middle of Sveden and our winter isn´t as it have been years ago. Rain when it shall snow, +5 when it should be -5.

Somthing is very, very wrong with our weather today.

well we are starting to do our bit here we are getting some solar panels (1KW with 2KW inverter) installed which should reduce the amount of co2 by about 1 Kg per 1KW we are producing from sun so on average we should be reducing our green house gas (co2) by 5 kg per day or 1500kg per year (apparently 300 days of good weather here) or when we get another 1KW of solar panels 10 kg per day or 3000kg per year

we are talking about making a compost some how here from kitchen scraps, lawn clippings ect in an effort to reduce the amount of methane we are producing but other then increasing the soil quality here i don't think it will make any difference to the amount of CH4 we are producing just changing location where methane is produced ?

we are also looking at collecting rain water for watering garden and maybe flushing toilet

Jes, Danish Dynamite a very god beginning. It is possible for me for ex. use a large solar panel during the spring, summer, authum and other days when it is sunchine. If we can get warm wather for dish, shower, layndry and other as need warm wather.

We dont need our furnace. Many use electric to heat up their houses and it is wery expencive today. If a houseovner install solar panels he gets his money back after a few year.

i guess i should have made it a bit clearer we are getting grid connected solar power PhotoVoltaic system not solar hot water, currently we have instantaneous gas hot water we might get solar hot water at a later date (if these any room left on roof lol)

I'm not sure how efficient either solar water heating or solar photovoltaic panels are in Sydney. Maybe better suited to more northerly regions? You don't very many panels around the suburbs.

i did some looking around a while back on www.bcse.org.au found some links to spreadsheets from the Australian Government Department of the Environment, Water, Heritage and the Arts and till june 2008 was i think it was 9943 pv solar installations in all of Australia

below is from here

Your solar system will generate more electricity than a comparable solar system installed in Europe, for example where sunlight levels are much lower than in Australia. For example, Germany has an irradiation level of 751 KWh for every square meter per year, and Canberra's irradiation level is 1386 KWh of sunlight for every square meter. Germany has around 250,000 Solar Power Grid Connect Systems installed, whereas there are only approximately 3000 solar systems installed in Australia. Our abundance of sunlight is there waiting for us to utilize! Lets harness this renewable and clean energy source!

i think part of the problem with the lack of uptake of solar pv systems in Australia is the lack of feed in tariff in nsw and wa other states have feed in tariff of 3.88 to 4 (ie if you make 1 kw and your supple rate is 10 cents per kw you would get 38.8 to 40 cents per kw) apparently nsw and wa are waiting for government grants to run out before doing anything about feed in tariffs
