Read the following passage and answer the item that follows. Your answer to this item should be based on the passage only.

Records kept at high altitude lakes in the Himalaya show the ice breaking up earlier decade by decade, and the melt itself now stretched over a longer stretch of weeks than it used to be. The flowering of the meadows around those lakes has moved forward with it, but not by the same number of days, so events that once arrived together now arrive apart. Herders who time their ascent by the old signs find the pasture already past its best when they reach it.

With reference to the above passage, the following assumptions have been made:

1. A warming climate is causing the mountain spring to begin earlier and to last longer.

2. The earlier and longer spring is not good for populations of pollinating insects.

Which of the above assumptions is/are correct?
