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.
Yellow leaves are typical in fall, but not in summer. Birch trees (Betula spp.) add interesting architectural form to your garden landscape. They thrive in U.S. Department of Agriculture plant hardiness zones 5 to 8, though the specific zone varies by species. Most birches produce leaves that yellow and drop in fall. If it's still summer and your birch tree leaves are turning yellow, the tree is telling you it has a problem. Most issues are easily resolved.
