In North America, the temperate rainforests have been changing in noticeable ways. These observed changes include deforestation for land use and agriculture, forest fires and species migration. With warming temperatures, drought is a major issue as the humidity in these rainforests is dropping. With this change, species that are well adapted to high moisture will suffer. Marine birds that are native to North America are slowly dying out as invasive species begin to make home in the drying forest and hunt their nests. Future changes to the rainforests are expected to include the conversion of forests to grasslands as the trees adapt to their new changing climate. The consequences on rainforests vary, with some areas begining to have more trees than before and others less so as rain patterns do fluctuate. It is also estimated that forest fire numbers will almost double by the end of the century diminishing massive areas of rainforest.<ref>NR.Can (2016, 07, 18). Impacts [Online].

Climate change has a massive impact on Earth’s rainforests. Whether it is North America’s temperate rain forests or the tropical rainforests in South America and beyond, climate change can affect these areas negatively. Climate scientists in Canada have been monitoring the rainforests over the last few decades to analyze the changes occurring on the west coast. Rainforests are home to 40-75% of living beings on Earth, they provide over one third of all oxygen produced and capture massive amounts of carbon dioxide every year.[1] The most notable changes observed today in rainforests are:

  • Pest infestations
  • Increased number of forest fires per year
  • Larger susceptibility to disease
  • Higher volume of invasive species
  • Tree growth pattern changes

However, these changes are observed differently based on the type of rainforest under observation.[2]

Impacts on Temperate Rainforests

In North America, the temperate rainforests (such as in Figure 1) have been changing in noticeable ways. These observed changes include deforestation for land use and agriculture, forest fires, and species migration. With warming temperatures, drought is a major issue as the humidity in these rainforests is dropping. With this change, species that are well adapted to high moisture will suffer. Marine birds that are native to North America are slowly dying out as invasive species begin to make home in the drying forest and hunt their nests.

Future changes to the rainforests are expected to include the conversion of forests to grasslands as the trees adapt to their new changing climate. The consequences on rainforests vary, with some areas beginning to have more trees than before and others less so as rain patterns do fluctuate. It is also estimated that forest fire numbers will almost double by the end of the century diminishing massive areas of rainforest.[3]

Impacts on Tropical Rainforests

Observed changes to tropical rainforests include fluctuations in rainfall patterns causing rainforests to slowly dry out. In some cases, tropical rainforests are expected to have higher storm intensity and (similar to temperate rainforests) species migration. Fluctuations in rainfall pattern is the greatest threat to this ecosystem. For example, it has been observed that in the Western Amazon there has been an increase in rain, comparatively the eastern Amazon is showing fewer rainfall events, which is causing drought. Drought can have major impacts on a rainforest, as they are incredibly important for capturing and storing atmospheric carbon. As the rainforest dries out, the trees will be much more susceptible to fire and disease causing the release of massive amounts of carbon dioxide back into the atmosphere, potentially increasing the greenhouse effect. This drying of the rainforests will bring about desertification, causing a major influence on the ecosystem. Native species will start moving out to more preferable climates becoming an invasive species to their new area.[4][5]

Figure 2 below shows a map of both temperate rainforests and tropical rainforests.
