Thirsty future ahead as climate change explodes plant growth

Climate change is triggering similar effects on the incidence and severity of disease for crops in agriculture and wild plants in natural communities. The complexity of natural ecosystems, however, generates a complex array of interactions between wild plants and pathogens in marked contrast to those generated in the structural and species simplicity of most agricultural crops. Understanding the different impacts of climate change on agricultural and natural ecosystems requires accounting for the specific interactions between an individual pathogen and its host s and their subsequent effects on the interplay between the host and other species in the community. Ultimately, progress will require looking past short-term fluctuations to multiyear trends to understand the nature and extent of plant and pathogen evolutionary adaptation and determine the fate of plants under future climate change.

By the end of the century plants could consume substantially more water, leaving less for people across North America, Europe, and Central Asia—even if it rains and snows more, a new study reports today in the journal Nature Geoscience. Plants are the primary regulators of the water cycle, responsible for 60 percent of the flow of water from the land to the atmosphere. Research now shows how climate change is altering this vital cycle in several different ways. Those hotter, CO 2 -rich future conditions are akin to turning up the heat and pumping CO 2 into a greenhouse. The likely result, assuming no other limiting factors such as lack of nutrients, is an explosion of plant life. But that will leave considerably less water for people to use, said Mankin in an interview.

Effects of climate change on plant biodiversity

January 15, Global warming affects more than just plant biodiversity—it even alters the way plants grow. In Current Biology , the group presents its latest findings on the mechanism controlling growth at high temperatures. In the future, this could help breed plants that are adapted to global warming. Plants react much more sensitively to fluctuations in temperature than animals.

Jump to main content. Most plants and animals live in areas with very specific climate conditions, such as temperature and rainfall patterns, that enable them to thrive. Any change in the climate of an area can affect the plants and animals living there, as well as the makeup of the entire ecosystem. Some species are already responding to a warmer climate by moving to cooler locations. For example, some North American animals and plants are moving farther north or to higher elevations to find suitable places to live.

Climate change

Climate change is recognised as one of the biggest threats to our natural world and its biodiversity, as well as to global security, human health and well-being. We are already witnessing the early effects of climate change, with more frequent extreme weather events such as droughts, flooding and storms and changing seasonal patterns being seen around the world. Climate models also predict that sea levels will rise as a result of melting ice caps, with devastating consequences for low-lying areas. This has been caused by our oceans absorbing more carbon dioxide from the atmosphere. In addition, biodiversity is also exposed to the secondary, human-driven impacts of a changing climate.

Ecological networks are more sensitive to plant than to animal extinction under climate change

A changing climate means changing habitats, threatening vulnerable species. On a cold and bitter winter night, in a field of boulders beneath a thick layer of snow, a mountain pygmy possum sleeps safe and snug. Under this white blanket, the mountain pygmy possum can hibernate the winter away. This is just one example of an Australian species that stands to lose its habitat in the face of climate change. The world is heating up. The average temperature of the Earth's surface increased by an estimated 0. Note that the figures above use a compilation of both instrumental and proxy data.

Climate change has a significant direct effect on terrestrial animals , by being a major driver of the processes of speciation and extinction. This event decimated amphibian populations and spurred on the evolution of reptiles. Birds lay their eggs earlier than usual in the year, plants bloom earlier and mammals come out of their hibernation state earlier. Climate change is a natural event that has occurred throughout history. However, with the recent increased emission of CO 2 in the Earth's atmosphere, abrupt climate change has occurred. It has been hypothesized that anthropogenic greenhouse gas forcing has significantly influenced global climate since about before present Van Hoof Animals have had specific responses to climate change.

Natural ecosystems are one of our most precious resources, critical for sustaining life on the planet. The benefits humans derive from ecosystems are varied, from marketable products such as pharmaceuticals, to recreational opportunities such as camping, to ecosystems services such as erosion control and water purification. For many people, nature plays a powerful spiritual and aesthetic role in their lives, and many place a high value on the existence of wilderness and nature for its own sake. Despite the critical roles ecosystems play, these areas are increasingly threatened by the impacts of a growing human population through habitat destruction and air and water pollution. Added to these stresses comes a new threat — global climate change resulting from increased greenhouse gas concentrations in the atmosphere.
