Proposal for exchange
I can offer Canada's issues for the IPY in return. Canada has issued one souvenir sheet and 2 single stamp to commemorate this event. The souvenir sheet can be seen in a previous post and the single stamps are the ones that you can see in the souvenir sheet.
There is also a FDC which I have yet to present to you.
Lithuania's contribution to the IPY
If there were no the Earth’s atmosphere, which transmits sunlight like a greenhouse but keeps the Earth surface warm, the sunlight, reflected by the Earth’s surface, would instantly fade in the space. Gases accumulated in the atmosphere trap the heat given out by the Earth and cause the so-called greenhouse effect.
Power plants generating electricity and heat, vehicles, factories, and other activities of man increase the concentration of gasses around the Earth enhancing the greenhouse effect and leading to the increase in temperature and climate change.
The melting of polar ice caps, retreat of mountain glaciers, rising sea level, storms, floods, dry years, heat waves, and shortage of drinking water can be named as the consequences of climate change.
In order to stop climate change, it is necessary to reduce the emission of gases contributing to the greenhouse effect.
