What Does Climate Change look like ?
As the climate is heating up one of the results are that air currents are changing. Normally hurricanes travel over an area quickly, but global warming is changing that. Recent hurricanes have been stalling and staying over some areas for days.

Hurricane Dorian, Bahamas
In 2019 the Bahamas experienced the most devastating hurricane on record evident in these photos showing the loss of plants on the island. Hurricane Dorian battered the northern Bahama islands for nearly 40 hours in September 2019. For a hurricane to last this long is not normal. Global warming is causing the air currents to slow and hurricanes can hover over an area longer which results in a lot more destruction.

The pine beetle is about the size of a grain of rice. It eats tunnels under the bark of the ponderosa and other pine trees eventually killing the tree.
Normally, a few mountain pine beetles can help the forest by killing older and weak trees. This helps make the forest more productive. But, this recent large outbreak of beetles is doing more harm than good. It can affect water quality. It can affect the balance of the ecosystem. It can also convert the forest from a carbon sink to a carbon source.
