Effects of climate change
Soil carbon feedbackMeasurements from a long-term study in Harvard, Massachusetts, began tracking soil behavior in 1991. That research suggests global warming could trigger the…
Ice–albedo feedbackIce reflects far more solar energy back into space than open water or any other land cover. This simple physical property drives a powerful climate change…
Marine heatwaveIn the summer of 2011, a massive warming event struck the west coast of Australia. This unprecedented heat caused kelp forests to die back rapidly along…
Food securityIn 1996, the World Food Summit gathered in Rome to redefine a term that had long been misunderstood. The conference declared food security exists when all…
Effects of climate change on oceansIn 2022, the global ocean reached its warmest recorded temperature in human history. This milestone followed a steady rise in heat content that exceeded the…
Sea level riseThe global average sea level has risen about 20 centimeters since 1880. This steady climb accelerated dramatically after the 1970s, reaching a rate of 4.62…
Atlantic meridional overturning circulationThe Atlantic meridional overturning circulation moves warm, saline water northward in the upper layers of the ocean. This flow originates from the tropical…
Effects of climate change on human healthIn 2019, an estimated 345,000 people over the age of 65 died from heat exposure. This figure represents a record high for that demographic group during that…
Effects of climate changeThe 20th century was the hottest in nearly 2,000 years. Scientists have studied tree rings and ice cores to understand this rapid change.
Coral bleachingIn 1985, a coral polyp in the Great Barrier Reef expelled its microscopic algae partners when water temperatures rose just one degree above average.
Effects of climate change on the water cycleA warmer atmosphere can hold more water vapor. This relationship follows the Clausius-Clapeyron equation. The law states that saturation vapor pressure…
Tropical cyclones and climate changeTropical cyclones draw their energy from warm, moist air. This fuel source becomes more potent as ocean temperatures rise due to human-induced climate change.
Extreme weatherA weather event becomes extreme when it falls outside the historical distribution for a specific location. Scientists use thresholds to identify these…
Climate change in the ArcticOn the 20th of June 2020, a temperature measurement inside the Arctic Circle reached 38 degrees Celsius. This heat was expected in the region only by the…
Extinction risk from climate changeIn 2019, the Australian government officially confirmed that the Bramble Cay melomys had gone extinct. This small rodent lived on a low-lying island in the…
Effects of climate change on agricultureThe 2003 European heatwave caused 13 billion euros in uninsured agricultural losses. This event marked a turning point where extreme weather began to visibly…
Greenhouse effectJoseph Fourier proposed the existence of heat-trapping gases in 1824. He argued that Earth's atmosphere retains solar energy to keep the planet warmer than…
Retreat of glaciers since 1850Alaska's McCarty Glacier retreated about 10 kilometers in less than a century, and dense, diverse vegetation has become established on the slopes.
