Yet to what extent do the Lisbon Treaty commitments to solidarity underpin these policies? This panel will examine the relevance of solidarity in European climate change commitments and will ask, in the world beyond 2020 and shaped by the Paris Agreement for the governance of the Energy Union, what will solidarity become?

According to the Missouri Botanical Garden, heat stress or fungal disease can lead to the yellowing of hosta. Scorch or heat stress leads to browning leaf margins and yellow areas between the main leaf veins. Fungal disease causes the base of the leaves to rot, which causes leaves to yellow.
The amount of sunlight and its intensity also determines the color of a hosta. Too much sun can have a range of effects, including burning, lightening (bleaching), browning and shriveling the leaves. Some hostas such as H. âJuneâ (see images) can show drastically different colors based on the amount of sunlight.
