Global warming may lead to melting and breaking apart of particularly vulnerable glaciers and ice sheets around the world in ways that could threaten livelihoods and regional economies (Oppenheimer and Alley, 2005). Science , this issue p. [255][1]; see also p. [184][2] The magnitude and pace of global change demand rapid assessment of nature and its contributions to people. More specifically, changes to near-surface air temperatures will likely influence ecosystem functioning and thus the biodiversity of plants, animals, and other forms of life.The current geographic ranges of plant and animal species have been established by adaptation to long-term seasonal climate patterns. It is, however, a challenging subject to teach. And it makes some extreme weather events more severe. It is now clear that global warming is mostly due to man-made emissions of greenhouse gases (mostly CO 2). Global Climate Change: Vital Signs … This century, an unprecedented combination of climate change, associated disturbances, and other global change drivers will likely exceed many ecosystems’ capacities for resilience. Until now the effects of global warming/climate change have been proportionate to increases in greenhouse gas concentrations. Global warming and climate change. Here is a look at 10 of the most common myths about climate change that persist in the public sphere and what science has to say about them. The Physical Science behind Climate Change. Climate change is a fundamental challenge for humanity as it deeply and pervasively affects the way we live on the planet. He said climate sensitivity above 5C would reduce the scope for human action to reduce the worst impacts of global heating. Global Change Research Program 4,5, and the Intergovernmental Panel on Climate Change 6 that global climate has warmed recently in response to increasing concentrations of greenhouse gases, especially carbon dioxide (CO 2), and … Over the last century, atmospheric concentrations of carbon dioxide increased The U.S. Navy has developed Arctic and climate change roadmaps to guide the way it adapts to climate change. Global Warming. While the basic physical principles of global warming are simple, however, the more detailed science of climate change … We are deeply disturbed by the recent escalation of political assaults on scientists in general and on climate scientists in particular. Panel on Climate Change (IPCC 2007) dispelled many uncertainties about climate change. Warming temperatures on land and sea, more frequent heat waves, stronger and wetter hurricanes, and hotter, drier, more intense wildfire seasons are the fingerprints of climate change. These complex and nonlinear forest-atmosphere interactions can dampen or amplify anthropogenic climate change. General cir-culation models of the atmosphere were originally developed for numerical weather forecasting (e.g., Phillips 1956). Reducing the level of climate change and reducing human vulnerability to whatever climate changes do occur depend on the understanding of climate science, engineering capabilities, and other kinds of knowledge, such as understanding of human behavior and on applying that knowledge wisely in decisions and activities. When the last shimmering autumn leaves drift to the ground, it doesn't just mark a seasonal change. Myth #1: It's the sun. The July 2020 temperatures soared across Siberia and reached a record-breaking 38°C inside the Arctic Circle, continuing a line of record heat events globally. This animation shows warming of the Earth's surface according to the results of climate model (called the NCAR Community Climate System Model) from 1870-2100. Global warming and climate change have the potential to alter biological systems. This review summarizes recent literature on the influence of temperature on coral growth, coral bleaching, … Global environmental change and sustainability science are found on experiments, tests, and the need to address the future through quantitative-based forecasts. Yet, many still deny or fail to understand how human activity, especially the burning of fossil fuels, is causing global warming and climate change. CRS Report. 2006).Although most attention has focused on CO 2, methane and N 2 O—both extremely potent GHGs—have greater global warming potentials (GWPs) than does CO 2.By assigning CO 2 a value of 1 GWP, the warming potentials of these other gases can be expressed on … Vital Signs of the Planet: Global Climate Change and Global Warming. climate change, global climate change, global warming, natural hazards, Earth, environment, remote sensing, atmosphere, land processes, oceans, volcanoes, land cover, Earth science data, ... comprehensive picture of climate science; for a complete review of global warming and climate change, please see our Global Warming Factsheet. Warming of the climate system is now unequivocal. Turner II, in International Encyclopedia of Human Geography, 2009. review the climate change–impact literature, expanding on the recent report of the Intergovernmental Panel on Climate Change. Global warming/climate change can cause both increases and decreases in local temperatures and precipitation. Science The Fundamentals Climate Change at the National Academies (Science, Engineering, Medicine). Scientists use climate models to better understand how Earth’s climate changed in the past, how it is changing now and to predict future climate trends. in climate science (Edwards 2001). Climate change and global warming have severe consequences for the survival of scleractinian (reef-building) corals and their associated ecosystems. Land-change modeling has been served by advances in the geographical information sciences (GIScs) … Thus, there is a need to educate today’s students, tomorrow’s leaders and decision makers, about global warming and climate change. Climate sceptics have seized on the temperature trends as evidence that global warming has ground to a halt. Hoegh-Guldberg et al. NASA’s Climate Kids website brings the exciting science of climate change and sustainability to life, providing clear explanations for the big questions in climate science. Partial list of leading scientific organizations endorsing human-induced climate change, along with a selection of related resources. The world's forests influence climate through physical, chemical, and biological processes that affect planetary energetics, the hydrologic cycle, and atmospheric composition. Global climate models or Earth system models (ESMs) are Modeling is essential in either case. There is always some uncertainty associated with scientific conclusions; science never absolutely proves anything. From: The Behavioral Economics of Climate Change, 2017. Climate change is here, whether we like it or not, and the Arctic is one of the fastest-changing places on the planet. ... leading to global warming. Modeling. This simulation is one of many using the CCSM for the Fourth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC). Climate change will be the greatest threat to humanity and global ecosystems in the coming years, and there is a pressing need to understand and communicate the impacts of warming, across the perspectives of the natural and social sciences. The Geological Society of America (GSA) concurs with the National Academies of Science, Engineering, and Medicines 1,2, the National Research Council 3, the U.S. Heat extremes on Earth have reached a disturbing new level in recent years. All citizens should understand some basic scientific facts. Encyclopedia of Earth: Climate Change "Evolving Assessments of Human and Natural Contributions to Climate Change," by Jane A. Leggett, Specialist in Energy and Environmental Policy, Congressional Research Service.February 1, 2018. B.L. The coupling of global atmospheric and oceanic models began with Manabe and Bryan (1969) and came of age in the 1980s and 1990s.
