Climate change is profoundly impacting the planet’s biodiversity, creating a cascade of effects that threaten the delicate balance of ecosystems and the myriad forms of life they support. As global temperatures rise, shifting weather patterns and increasing frequency of extreme events disrupt natural habitats, leading to significant changes in species distribution, interactions, and survival.

One of the primary ways climate change affects biodiversity is through habitat loss and alteration. Rising temperatures and changing precipitation patterns can transform ecosystems at a rapid pace. For instance, warming temperatures are causing polar ice to melt, which impacts species that depend on ice-covered habitats, such as polar bears and seals. Similarly, coral reefs, which are highly sensitive to temperature changes, are experiencing widespread bleaching events due to increased sea temperatures. The loss of these critical habitats leads to a decline in species that rely on them, disrupting entire marine ecosystems.
Shifts in species distributions are another significant consequence of climate change. As temperatures rise, many species are migrating towards cooler areas, often moving poleward or to higher elevations. This shift can lead to changes in community composition and interactions, as species that once coexisted may now compete for resources or face new predators. For example, in mountainous regions, plants and animals are moving up in altitude, but as the available space shrinks, some species may face extinction if they cannot move further up the mountain or adapt to new conditions.
