But more severe droughts and more hot days are likely to reduce yields, especially in the western half of Kentucky, which in seventy years is likely to have 15 to 30 more days with temperatures above 95°F than it has today. Even on irrigated fields, higher temperatures are likely to reduce yields of corn, and possibly soybeans.
This is the largest giant sequoia (Sequoiadendron giganteum) among more than a dozen that were planted early in the 20th century in Laurelhurst Park of Portland, Oregon. The tallest tree in the world is the coast redwood; the most massive tree is the closely related giant sequoia. Both have non-overlapping native ranges limited to California ...
The Earth’s albedo has been declining since the 1970s, according to the report, due in part to the melting of light-colored snow and sea ice, exposing darker land and water which absorb more of ...
Trees account for more than a quarter of the species on the International Union for the Conservation of Nature's Red List. The number of threatened trees is more than double the number of ...
The more trees that are removed equals larger effects of climate change which, in turn, results in the loss of more trees. [13] Forests cover 31% of the land area on Earth. Every year, 75,700 square kilometers (18.7 million acres) of the forest is lost. [14] There was a 12% increase in the loss of primary tropical forests from 2019 to 2020. [15]
Global warming is currently tracked by comparing temperatures to the “pre-industrial era,” before humans started burning large amounts of fossil fuels, widely defined as the period between ...
This corresponds to more than 20% likelihood of extinction over the next 10–100 years under the IUCN criteria. [41] [42] The 2022 IPCC Sixth Assessment Report estimates that while at 2 °C (3.6 °F) of global warming, fewer than 3% of flowering plants would be at a very high risk of extinction, this increases to 10% at 3.2 °C (5.8 °F).

[32] [33]: 1057 In some tropical and subtropical regions of the world, there will probably be less rain due to global warming. This will make them more prone to drought. Droughts are set to worsen in many regions of the world. These include Central America, the Amazon and south-western South America. They also include West and Southern Africa.
