The effects of climate change on plant biodiversity can be predicted by using various models, for example bioclimatic models. [5] [6] Habitats may change due to climate change. This can cause non-native plants and pests to impact native vegetation diversity. [7] Therefore, the native vegetation may become more vulnerable to damage. [8]
The report concluded that global warming of 2 °C (3.6 °F) over the preindustrial levels would threaten an estimated 5% of all the Earth's species with extinction even in the absence of the other four factors, while if the warming reached 4.3 °C (7.7 °F), 16% of the Earth's species would be threatened with extinction.
In the year 2004, it was estimated that 2,520,000 metric tons of explosive agents were sold for consumption in the United States alone. [6] Figure 1 shows the world consumption of explosives in 2008. [7] Generally, explosives are dispersed mainly when used in combat. Most explosives are used as warfare agents by militaries globally.
Data shows CO2 is also causing modern global warming − and an array of negative consequences − by slowing the escape of heat energy into space. CO2 can fertilize plants and also drive global ...
Global Warming of 1.5°C. An IPCC Special Report on the impacts of global warming of 1.5°C above pre-industrial levels and related global greenhouse gas emission pathways, in the context of strengthening the global response to the threat of climate change, sustainable development, and efforts to eradicate poverty. pp. 49–91.
Epilobium hirsutum seed head dispersing seeds. In spermatophyte plants, seed dispersal is the movement, spread or transport of seeds away from the parent plant. [1] Plants have limited mobility and rely upon a variety of dispersal vectors to transport their seeds, including both abiotic vectors, such as the wind, and living vectors such as birds.
The Arctic was historically described as warming twice as fast as the global average, [40] but this estimate was based on older observations which missed the more recent acceleration. By 2021, enough data was available to show that the Arctic had warmed three times as fast as the globe - 3.1°C between 1971 and 2019, as opposed to the global ...
The significance of the multiple dispersal steps on the plant fitness and population dynamics depends on the type of dispersers involved. In many cases, secondary seed dispersal by (typically granivorous ) invertebrates or rodents moves seeds over a relatively short distance and a large proportion of the seeds may be lost to seed predation ...
