A rain shadow is a dry area on the leeward side of a mountainous area (away from the wind). The mountains block the passage of rain-producing weather systems and cast a "shadow" of dryness behind them. Wind and moist air are drawn by the prevailing winds towards the top of the mountains, condensing and precipitating before it crosses the top.
Overexploitation, also called overharvesting or ecological overshoot, refers to harvesting a renewable resource to the point of diminishing returns. [2] Continued overexploitation can lead to the destruction of the resource, as it will be unable to replenish.
23% of tree cover losses result from wildfires and climate change increase their frequency and power. [20] The rising temperatures cause massive wildfires especially in the Boreal forests. One possible effect is the change of the forest composition. [21] Deforestation can also cause forests to become more fire prone through mechanisms such as ...
Ecological overshoot expressed in terms of how many Earths equivalent of natural resources are consumed by humanity each year. Ecological overshoot is the phenomenon which occurs when the demands made on a natural ecosystem exceed its regenerative capacity. Global ecological overshoot occurs when the demands made by humanity exceed what the ...
[52] An analysis of the geoengineering proposals published in Nature Communication confirmed findings of the SR15, stating that "all are in early stages of development, involve substantial uncertainties and risks, and raise ethical and governance dilemmas. Based on present knowledge, climate geoengineering techniques cannot be relied on to ...
Later, as climate change, drought and a century of fire suppression started fueling bigger and more intense fires, the connection to trains surfaces again in O'Connor's text when she writes about ...
Climate endgame is a term used to refer to the risk of societal collapse and potential human extinction due to the effects of climate change. [3] The usage of the term seeks to improve risk management by putting a higher priority on worst-case scenarios , to "galvanise action, improve resilience, and inform policy ".
World leaders are meeting in Paris this month in what amounts to a last-ditch effort to avert the worst ravages of climate change. Climatologists now say that the best case scenario — assuming immediate and dramatic emissions curbs — is that planetary surface temperatures will increase by at least 2 degrees Celsius in the coming decades.
