According to the graphs, caterpillars now reach their peak biomass on May 15 instead of May 28, causing them to no longer align with bird hatchling food needs.
Which of the following best explains what could have caused this shift in caterpillar timing?

Bird hatchlings now require food earlier in May rather than late May.

Warmer spring temperatures are causing caterpillars to develop and mature earlier than they did in 1980

Birds have evolved to lay eggs later in the season to match the new caterpillar schedule.

Caterpillars are eating different plants that grow later in the season.

Due to the change in timing, what is the most likely consequence for the bird population?

Birds will migrate earlier to find food

Chicks will starve because caterpillars have already pupated

Caterpillars will evolve to delay their development

Bird populations will increase due to less competition

The American pika is a small, mountain-dwelling rodent that is extremely sensitive to temperature changes.
Scientists have been monitoring the elevations at which pikas are found across the western United States:
What trend is shown in the pika elevation data?

Pikas have remained at the same elevation, showing no response to environmental changes.

Pikas have moved to lower elevations over time because mountains are becoming cooler.

Pikas have moved to higher elevations over time because mountains are becoming warmer.

Pikas have moved to lower elevations to find more food and vegetation.

If pikas continue moving upward at the same rate shown in the data (approximately 10.6 m per year), what would eventually happen to the pika population?

The population would stabilize once pikas reach the mountain summit

The population would continue to thrive indefinitely.

The population would increase because cooler temperatures support more pikas.

The population would decline because pikas would run out of higher elevations to move to.

If peak snowpack is now occurring 21 days earlier (as shown by reddish circles), how would this affect the water available for agriculture during summer?

Agriculture would not be affected by snowpack timing

Water reservoirs would automatically adjust the timing

Agriculture would have MORE water because snowpack melts earlier

Agriculture would have LESS water because snowmelt occurs before the peak growing season

Based on the snowpack map showing earlier peak snowpack, what might be a consequence for aquatic ecosystems?

Streamflow would be higher in summer, benefiting fish populations

Streamflow would be lower in summer when many aquatic organisms need water most

Ecological systems would not be affected by snowpack timing changes

Fish would migrate earlier to adjust to the new water schedule

Select a different state of your choice, and use the Climate Impact Map to research its historical and projected temperature data for the same time periods shown in the Washington data table (1986-2005, 2020-2039, 2040-2059, 2080-2099).
Choose TWO of the following:
Average Jun/Jul/Aug Temps
Average Dec/Jan Feb Temps
Average Annual Temps
#Days < 32°F
#Days > 95°F
Compare those TWO specific data points between your selected state and Washington with supporting data.
