After hot summer in Finland with many tropical nights (temperature does not down below 20 C) nice to be back in cool Kenya. Morning temperature 13 degrees and we may have it over 20 degrees today. This is Kenyan winter they say. #kenya, #tropics, #helsinkiuni
When temperatures rise, forests protect their denizens. Researchers have shown that with increasing temperatures, the buffering capacity of maximum temperatures of global forests also increases. #HelsinkiSustainability #climatechange #globalwarming https://t.co/GvAaGhGF9D
Summer heat waves are strongly moderated below the tree canopy, shows a new study. In forests, maximum temperature is, on average across the globe, 4 degrees lower than outside forests. This protects plants and animals against climate warming.
Forest canopies buffer the effects of climate change and protect the animals against warming. The maximum temperature in forests is, on average across the globe, 4 degrees lower than outside forests. #climatechange #climatecrisis #HelsinkiSustainability https://t.co/KF6guCC61w

We often think mountain nature is primarily limited by low temperatures. In a study, soil moisture emerged as one of the most significant environmental variables in the mountains, determining where each plant, moss, and lichen species may grow. Measurements reveal that the humidity of the soil varies in the undulating terrain of the fells from one extreme to another even within a few metres.
Reduced snow cover may be an even larger threat to the Arctic plants than rising temperatures. Snow provides shelter for plants from winter-time extreme events. At the same time it shortens the length of growing season, which prevents the establishment of more southern plants. Many of the northern plant species are already endangered, which makes their conservation an urgent challenge.
Northern peatlands slow climate change over the coming decades, new research suggests. Rising temperatures will lengthen the growing season in northern latitudes, which allows plants growing in northern peatlands to absorb more carbon from the atmosphere through photosynthesis. Once these plants die, the acidic and waterlogged conditions of peatland environments slow the decomposition process.
A new, more detailed model shows that even in the best-case scenario, permafrost in the Arctic will reduce at least one third by year 2050. Greatest changes will happen in areas where current soil temperatures are low.
Job description for urban trees could be something like this: - provide shelter and diverse habitats for many species - absorb carbon, which curbs greenhouse gas emissions - decrease temperatures by offering shade and evaporating water - decrease the risk of urban flooding - provide city residents with aesthetic pleasure and comfort. Researchers aim to create models on how various species of trees grow and function in varying surroundings. New technologies, such as laser scanning based on remote sensing, are needed to find out such details. This way they can imagine what certain areas and their tree stand will look like in, say, 40 years.
