Climate change feedback. Quantifying the consensus on anthropogenic global warming in the scientific literature. This letter was conceived as a 'citizen science' project by volunteers contributing to the Skeptical Science website ( www.skepticalscience.com ).
In March 2012, we searched the ISI Web of Science for papers published from 1991–2011 using topic searches for 'global warming' or 'global climate change'. Article type was restricted to 'article', excluding books, discussions, proceedings papers and other document types. The search was updated in May 2012 with papers added to the Web of Science up to that date.

Global Warming's Terrifying New Math. If the pictures of those towering wildfires in Colorado haven't convinced you, or the size of your AC bill this summer, here are some hard numbers about climate change: June broke or tied 3,215 high-temperature records across the United States.
That followed the warmest May on record for the Northern Hemisphere – the 327th consecutive month in which the temperature of the entire globe exceeded the 20th-century average, the odds of which occurring by simple chance were 3.7 x 10-99, a number considerably larger than the number of stars in the universe. Meteorologists reported that this spring was the warmest ever recorded for our nation – in fact, it crushed the old record by so much that it represented the "largest temperature departure from average of any season on record. " The Spencer Challenge to Slayers/Principia. Dr.
Roy Spencer has made a challenge to the Slayers/Principia folks who keep insisting the greenhouse effect doesn’t exist at all. For example, see the front page claim at right from the Principia web page where they claim the greenhouse effect is “bogus”. My view has always been that it exists. and has been effectively modeled as well as observed/measured (up to a point, so far I don’t know of a full scale measurement being done for the entire vertical column of the atmosphere), but likely isn’t the catastrophic issue portrayed by alarmists due to climate sensitivity likely being low.
Dr. Spencer’s challenge is quite simple and rooted in science; to prove their case, he simply wants them to make a simple model like this one below to demonstrate the absence of a greenhouse effect, while at the same time handling the measured energy budget of the Earth. Time for the Slayers to Put Up or Shut Up. I have allowed the Sky Dragon Slayers to post hundreds of comments here containing their views of how the climate system works (or maybe I should say how they think it doesn’t work).
As far as I can tell, their central non-traditional view seems to be that the atmosphere does not have so-called “greenhouse gases” that emit thermal infrared radiation downward. A variation on this theme is that even if those gases exist, they emit energy at the same rate they absorb, and so have no net effect on temperature. I have repeatedly addressed these views and why they are false. As far as the Slayer’s alternative explanations go, I have addressed why atmospheric pressure cannot explain surface temperature. The atmospheric adiabatic lapse rate describes how temperature *changes* with height for an air parcel displaced vertically, it does not tell you what the temperature, per se, will be.
Determining the actual temperature at any altitude requires computing rates of energy gain and energy loss. Introduction - Summary. Introduction: A Hyperlinked History of Climate Change Science It is an epic story: the struggle of thousands of men and women over the course of a century for very high stakes.
For some, the work required actual physical courage, a risk to life and limb in icy wastes or on the high seas. Why Climate Deniers Have No Scientific Credibility - In One Pie Chart. Climate change and ecosystems. This article is about climate change and ecosystems.
Impacts[edit] Unchecked global warming could affect most terrestrial ecoregions. Increasing global temperature means that ecosystems will change; some species are being forced out of their habitats (possibly to extinction) because of changing conditions, while others are flourishing. Secondary effects of global warming, such as lessened snow cover, rising sea levels, and weather changes, may influence not only human activities but also the ecosystem. London Climate Change Agency. The London Climate Change Agency Limited (LCCA), was a municipal company owned by the London Development Agency (LDA) that worked in partnership with private sector companies (notably EDF Energy) to design, finance, construct, own and operate decentralised low energy and zero-carbon projects for London, as well as providing services to others.
It operated in the areas of energy, water, waste and transport. Effects of climate change on humans. Flooding in the U.S.
Midwest June 2008. Climate change has brought about severe and possibly permanent alterations to our planet’s geological, biological and ecological systems.[1] The Intergovernmental Panel on Climate Change (IPCC) contended in 2003 that “there is new and stronger evidence that most of the warming observed over the last 50 years is attributable to human activities”.[2] These changes have led to the emergence of large-scale environmental hazards to human health, such as extreme weather,[3] ozone depletion, loss of biodiversity,[4] stresses to food-producing systems and the global spread of infectious diseases.[2] The World Health Organization (WHO) estimates that 160,000 deaths, since 1950, are directly attributable to climate change.
Many believe this to be a conservative estimate.[5] Key vulnerabilities[edit] Health[edit] Green Climate Fund. The Green Climate Fund (GCF) is a fund within the framework of the UNFCCC founded as a mechanism to transfer money from the developed to the developing world, in order to assist the developing countries in adaptation and mitigation practices to counter climate change.
The GCF is based in the new Songdo district of Incheon, South Korea. It is governed by a Board of 24 members and initially supported by an Interim Secretariat. ‘The Green Climate Fund will support projects, programmes, policies and other activities in developing country Parties using thematic funding windows’.[1] It is intended to be the centrepiece of efforts to raise Climate Finance of $100 billion a year by 2020. Climate sensitivity. Frequency distribution of climate sensitivity, based on model simulations.[1] Few of the simulations result in less than 2 °C of warming—near the low end of estimates by the Intergovernmental Panel on Climate Change (IPCC).[1] Some simulations result in significantly more than the 4 °C, which is at the high end of the IPCC estimates.[1] This pattern (statisticians call it a "right-skewed distribution") suggests that if carbon dioxide concentrations double, the probability of very large increases in temperature is greater than the probability of very small increases.[1] Although climate sensitivity is usually used in the context of radiative forcing by carbon dioxide (CO2), it is thought of as a general property of the climate system: the change in surface air temperature (ΔTs) following a unit change in radiative forcing (RF), and thus is expressed in units of °C/(W/m2).
For coupled atmosphere-ocean global climate models (e.g. Eike-klima-energie.eu/fileadmin/user_upload/Bilder_Dateien/Leistenschneider_Heliospheric_Current_Sheet/Abbildung_94.JPG. Final Report of Synthesis and Assessment Product 1.1. This document, the first of the Synthesis and Assessment Products described in the U.S. Climate Change Science Program (CCSP) Strategic Plan , was prepared in accordance with Section 515 of the Treasury and General Government Appropriations Act for Fiscal Year 2001 (Public Law 106-554) and the information quality act guidelines issued by the Department of Commerce and NOAA pursuant to Section 515). The CCSP Interagency Committee relies on Department of Commerce and NOAA certifications regarding compliance with Section 515 and Department guidelines as the basis for determining that this product conforms with Section 515. For purposes of compliance with Section 515, this CCSP Synthesis and Assessment Product is an “interpreted product” as that term is used in NOAA guidelines and is classified as “highly influential”.

Instead of being “wasted” by release into the ambient environment, sometimes waste heat (or cold) can be utilized by another process, or a portion of heat that would otherwise be wasted can be reused in the same process if make-up heat is added to the system (as with heat recovery ventilation in a building). Thermal energy storage, which includes technologies both for short- and long-term retention of heat or cold, can create or improve the utility of waste heat (or cold). One example is waste heat from air conditioning machinery stored in a buffer tank to aid in night time heating.
Another is seasonal thermal energy storage (STES) at a foundry in Sweden. On a biological scale, all organisms reject waste heat as part of their metabolic processes, and will die if the ambient temperature is too high to allow this. Anthropogenic waste heat is thought by some to contribute to the urban heat island effect. United Nations Framework Convention on Climate Change. The United Nations Framework Convention on Climate Change (UNFCCC) is an international environmental treaty negotiated at the United Nations Conference on Environment and Development (UNCED), informally known as the Earth Summit, held in Rio de Janeiro from 3 to 14 June 1992.
The objective of the treaty is to "stabilize greenhouse gas concentrations in the atmosphere at a level that would prevent dangerous anthropogenic interference with the climate system".[2] The treaty itself set no binding limits on greenhouse gas emissions for individual countries and contains no enforcement mechanisms. In that sense, the treaty is considered legally non-binding. Instead, the treaty provides a framework for negotiating specific international treaties (called "protocols") that may set binding limits on greenhouse gases. Intergovernmental Panel on Climate Change. The Intergovernmental Panel on Climate Change (IPCC) is a scientific intergovernmental body under the auspices of the United Nations,[1][2] set up at the request of member governments.[3] It was first established in 1988 by two United Nations organizations, the World Meteorological Organization (WMO) and the United Nations Environment Programme (UNEP), and later endorsed by the United Nations General Assembly through Resolution 43/53.
Membership of the IPCC is open to all members of the WMO and UNEP.[4] The IPCC is chaired by Rajendra K. Pachauri. The IPCC does not carry out its own original research, nor does it do the work of monitoring climate or related phenomena itself. The IPCC bases its assessment on the published literature, which includes peer-reviewed and non-peer-reviewed sources.[7] Adaptation to global warming. Adaptation to global warming is a response to climate change that seeks to reduce the vulnerability of biological systems to climate change effects.[1] Even if emissions are stabilized relatively soon, climate change and its effects will last many years, and adaptation will be necessary.[2] Climate change adaptation is especially important in developing countries since those countries are predicted to bear the brunt of the effects of climate change.[3] That is, the capacity and potential for humans to adapt (called adaptive capacity) is unevenly distributed across different regions and populations, and developing countries generally have less capacity to adapt (Schneider et al., 2007).[4] Adaptive capacity is closely linked to social and economic development (IPCC, 2007).[5] The economic costs of adaptation to climate change are likely to cost billions of dollars annually for the next several decades, though the amount of money needed is unknown.

World energy consumption. World Energy Consumption refers to the total energy used by all of human civilization. Typically measured per-year, it involves all energy harnessed from every energy source we use, applied towards humanity's endeavors across every industrial and technological sector, across every country. Being the power source metric of civilization, World Energy Consumption has deep implications for humanity's social-economic-political sphere. Institutions such as the International Energy Agency (IEA), the U.S. Energy Information Administration (EIA), and the European Environment Agency record and publish energy data periodically. Climate change denial. This article is about campaigns to undermine public confidence in scientific opinion on climate change. For the public debate over scientific conclusions, see global warming controversy.
Climate change denial is a denial or dismissal of the scientific consensus on the extent of global warming, its significance, and its connection to human behavior, especially for commercial or ideological reasons.[1][2] Typically, these attempts take the rhetorical form of legitimate scientific debate, while not adhering to the actual principles of that debate.[3][4] Climate change denial has been associated with the fossil fuels lobby, the Koch brothers, industry advocates and free market think tanks, often in the United States.[5][6][7][8][9] Some commentators describe climate change denial as a particular form of denialism.[10][11][12][13][14][15][16] Scientists Present 1998 Earth-Temperature Trends.
