This caused the Hennessey Fire to explode to 2,400 acres (9.7 km 2) by 5 PM August 17, prompting several evacuations. [47] By the night of August 18, the LNU complex had burned a total of 32,025 acres (129.60 km 2 ) so far with no containment. 3 structures were destroyed, and the two biggest fires, the Hennessey and the Gamble Fires, both ...
A flammagenitus cloud, [1] also known as a flammagenitus, pyrocumulus cloud, or fire cloud, is a dense cumuliform cloud associated with fire or volcanic eruptions. [2] A flammagenitus is similar dynamically in some ways to a firestorm , and the two phenomena may occur in conjunction with each other.
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 ...
The overshoot trajectory is typically defined as the shallowest-allowable entry velocity angle prior to atmospheric skip-off. The overshoot trajectory has the highest heat load and sets the TPS thickness. The undershoot trajectory is defined by the steepest allowable trajectory.
Cause: Slash-and-burn approach to deforest land for agriculture and effects of climate change and global warming due to unusually longer dry season and above average temperatures worldwide throughout 2019: Map; Amazon rainforest ecoregions as delineated by the WWF in white and the Amazon drainage basin in blue.
Climate change can also be used more broadly to include changes to the climate that have happened throughout Earth's history. [32] Global warming—used as early as 1975 [33] —became the more popular term after NASA climate scientist James Hansen used it in his 1988 testimony in the U.S. Senate. [34] Since the 2000s, climate change has ...
Pyrogeography is the study of the past, present, and projected distribution of wildfire.Wildland fire occurs under certain conditions of climate, vegetation, topography, and sources of ignition, such that it has its own biogeography, or pattern in space and time.
For people, "overshoot" is that portion of their demand or ecological footprint which must be eliminated to be sustainable, or the delta between a sustainable population and what we currently have. [1] [2] Excessive demand leading to overshoot is driven by both consumption and population. [3] Population decline due to overshoot is known as ...
