the Summer drought meant that the forest's capacity to take up carbon dioxide became worse.
The report Vetenskapsradion who have taken part of a research study around the extremvärmens impact on photosynthesis.
Through the process of photosynthesis takes woods up a large part of the greenhouse gases we emit.
But for the plants to convert carbon dioxide into glucose and oxygen need the water.
Measurements show that the net emissions of carbon dioxide during the summer was greater than in the busy, which is probably due to the drought.
This is uncommon, usually has a net uptake of carbon dioxide, " says researcher Johan Kuylenstierna to Vetenskapsradion.
