What are some consequences of global climate change?

The option highlighting increased disease and sea acidification accurately reflects the consequences of global climate change. As the climate warms, ecosystems shift, and habitats change unpredictably, leading to alterations in disease patterns. Warmer temperatures can expand the range of many pathogens and pests, as well as increase the reproduction rates of some diseases, contributing to heightened health risks for humans and wildlife alike.

Additionally, climate change is resulting in ocean acidification, primarily due to increased carbon dioxide (CO2) emissions being absorbed by the oceans. This process lowers the pH of seawater, which adversely affects marine life, particularly organisms that rely on calcium carbonate for their shells and skeletons, such as corals and some shellfish. As these foundational species struggle to survive, it disrupts marine ecosystems and the services they provide, impacting biodiversity and food security.

The other options do not accurately reflect the trends and consequences of global climate change. For instance, stable temperatures and low precipitation imply a lack of change, which contradicts the observed increasing variability in weather patterns. Similarly, decreased sea level is inconsistent with rising sea levels observed due to melting ice caps and glaciers as well as thermal expansion of seawater. Lastly, biodiversity loss typically accompanies climate change, but cooler summers would not be
