What is Climate?01:16

What is Climate?

Climate refers to the prevailing weather conditions in a specific area over an extended period. As the saying goes, “Climate is what you expect. Weather is what you get.” Climate is influenced by geographic factors, such as latitude, terrain, and proximity to bodies of water.
Global Climate Change01:50

Global Climate Change

Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.
Threats to Biodiversity01:50

Threats to Biodiversity

There have been five major extinction events throughout geological history, resulting in the elimination of biodiversity, followed by a rebound of species that adapted to the new conditions. In the current geological epoch, the Holocene, there is a sixth extinction event in progress. This mass extinction has been attributed to human activities and is thus provisionally called the Anthropocene. In 2019 the human population reached 7.7 billion people and is projected to comprise 10 billion by...
Responses to Drought and Flooding02:41

Responses to Drought and Flooding

Water plays a significant role in the life cycle of plants. However, insufficient or excess of water can be detrimental and pose a serious threat to plants.
Ecological Disturbance02:26

Ecological Disturbance

An ecological disturbance is a temporary disruption in the environment resulting from abiotic, biotic, or anthropogenic factors, causing a pronounced change in an ecosystem. The impact of an ecological disturbance, which can depend on its intensity, frequency, and spatial distribution, plays a significant role in shaping the species diversity within the ecosystem.Ecological disturbances can be caused by an event as small as the trampling of underbrush to an incident as wide-ranging as a forest...
Microbes and Climate Change01:27

Microbes and Climate Change

Microorganisms are pivotal agents in Earth's biogeochemical cycles, significantly influencing climate dynamics through their metabolic activities. These microbes modulate the levels of key greenhouse gases by both contributing to and helping mitigate climate change.Microbial Contributions to Greenhouse Gas EmissionsRising global temperatures accelerate microbial metabolism, which, in turn, speeds up the decomposition of organic matter. This process releases carbon dioxide (CO₂) through...

Background:

  • Climate change is increasingly impacting global ecosystems.
  • Ecological responses are observed across various environments, from polar to marine.
  • Flora and fauna exhibit changes at species and community levels.

Purpose of the Study:

  • To review and synthesize evidence of ecological impacts from recent climate change.
  • To identify patterns in ecological responses across different ecosystems.
  • To highlight the visibility of ecological changes even in the early stages of global warming.

Main Methods:

  • Literature review of studies on climate change impacts.
  • Synthesis of findings across diverse ecosystems and organizational levels.
  • Analysis of observed ecological responses in flora and fauna.

Main Results:

  • Ample evidence confirms ecological impacts of climate change globally.
  • Observed responses span terrestrial and marine ecosystems.
  • Coherent patterns of ecological change are evident across systems.

Conclusions:

  • Ecological responses to climate change are already clearly visible.
  • Despite uncertainties, a consistent pattern of ecological change is emerging.
  • These findings underscore the significant ecological consequences of ongoing global warming.
