Detection and Attribution of Climate Change: from Global to Regional

Atmospheric Temperatures More than half of the observed increase in global mean surface temperature (GMST) from 1951 to 2010 is very likely1 due to the observed anthropogenic increase in greenhouse gas (GHG) concentrations. The consistency of observed and modeled changes across the climate system, including warming of the atmosphere and ocean, sea level rise, ocean acidification and changes in the water cycle, the cryosphere and climate extremes points to a large-scale warming resulting primarily from anthropogenic increases in GHG concentrations. Solar forcing is the only known natural forcing acting to warm the climate over this period but it has increased much less than GHG forcing, and the observed pattern of long-term tropospheric warming and stratospheric cooling is not consistent with the expected response to solar irradiance variations. The Atlantic Multi-decadal Oscillation (AMO) could be a confounding influence but studies that find a significant role for the AMO show that this does not project strongly onto 1951–2010 temperature trends. {10.3.1, Table 10.1} It is extremely likely that human activities caused more than half of the observed increase in GMST from 1951 to 2010. This assessment is supported by robust evidence from multiple studies using different methods. Observational uncertainty has been explored much more thoroughly than previously and the assessment now considers observations from the first decade of the 21st century and simulations from a new generation of climate models whose ability to simulate historical climate has improved in many respects relative to the previous generation of models considered in AR4. Uncertainties in forcings and in climate models’ temperature responses to individual forcings and difficulty in distinguishing the patterns of temperature response due to GHGs and other anthropogenic forcings prevent a more precise quantification of the temperature changes attributable to GHGs. {9.4.1, 9.5.3, 10.3.1, Figure 10.5, Table 10.1} GHGs contributed a global mean surface warming likely to be between 0.5°C and 1.3°C over the period 1951–2010, with the contributions from other anthropogenic forcings likely to be between –0.6°C and 0.1°C, from natural forcings likely to be between –0.1°C and 0.1°C, and from internal variability likely to be between –0.1°C and 0.1°C. Together these assessed contributions are consistent with the observed warming of approximately 0.6°C over this period. {10.3.1, Figure 10.5} It is virtually certain that internal variability alone cannot account for the observed global warming since 1951. The observed global-scale warming since 1951 is large compared to climate model estimates of internal variability on 60-year time scales.

Stem Cell Primer - Stem Cell Information - National Institutes of Health

This primer on stem cells is intended for anyone who wishes to learn more about the biological properties of stem cells, the important questions about stem cells that are the focus of scientific research, and the potential use of stem cells in research and in treating disease. The primer includes information about stem cells derived from embryonic and non-embryonic tissues. Much of the information included here is about stem cells derived from human tissues, but some studies of animal-derived stem cells are also described. The National Institutes of Health (NIH) developed this primer to help readers understand the answers to questions such as: ff What are stem cells? ff What are the different types of stem cells, and where do they come from? ff What is the potential for new medical treatments using stem cells? ff What research is needed to make such treatments a reality? This document provides basic information about stem cells. More detailed discussion is available from the NIH stem cell reports at http://stemcells.nih.gov/info/. Quick answers to specific common queries can be found on the Frequently Asked Questions page. Throughout “Stem Cell Basics,” many technical terms appear in bold, underlined maroon type. Click the term to see its definition in the Glossary at the end of the primer.

Therapeutic perspectives of human embryonic stem cell research ...

Therapeutic perspectives of human embryonic stem cell research versus the moral status of a human embryo – does one have to be compromised for the other? Kristina Hug Department of Social Medicine, Faculty of Public Health, Kaunas University of Medicine, Lithuania Key words: embryonic stem cells, embryo status, biomedical research, religion. Summary. Stem cells are unspecialized cells able to divide and produce copies of themselves and having the potential to differentiate, i.e. to produce other cell types in the body. Because of the latter ability, the scientists investigate their possible use in regenerative medicine. Especially embryonic stem cells have huge therapeutic potential because they can give rise to every cell type in the body as compared to stem cells from certain adult tissues which can only differentiate into a limited range of cell types. For this reason scientists stress the importance of embryonic stem cell research. However, this research raises sensitive ethical and religious arguments, which are balanced against possible great benefit of such research for the patients suffering from so far incurable diseases. The objective of this literature review is to present the main arguments in favor and against human embryonic stem cell research. Since the sensitivity of the latter issue to a large extent stems from the position of predominant religions in a given society, the positions of the main religions regarding embryo research are also presented. Conclusion. There is no consensus regarding ethical aspects of human embryonic stem cell research. The article presents both the arguments supporting human embryonic stem cell research and the arguments opposing it.

Stem Cell Therapies in MS - pdf - MS Australia

Stem cell therapies in MS There is a great deal of scientific and media interest in stem cells as a possible treatment for multiple sclerosis (MS). Some scientific reports do reveal encouraging clinical findings, but a lot of work still needs to be done to prove their effectiveness and safety for people with MS. Stem cells in MS are still experimental. There is no proven stem cell therapy available for MS anywhere in the world. About this booklet This booklet has been written for and with people affected by MS. In it, we aim to explain the key issues around stem cells and MS. We look at what benefits someone might expect from a stem cell therapy and the different types of stem cells which are being researched for MS. We highlight why it is important to have properly controlled trials in this area also emphasising that we strongly discourage people with MS from approaching ‘stem cell clinics’ that are offering ‘stem cell therapies’ outside of an official clinical trial. The role of MS charities in stem cell research In May 2009, the MS societies of the UK and US held an international meeting in London to reach a consensus on stem cell therapies in MS.

Clinical trials for stem cell therapies - BioMed Central

In recent years, clinical trials with stem cells have taken the emerging field in many new directions. While numerous teams continue to refine and expand the role of bone marrow and cord blood stem cells for their vanguard uses in blood and immune disorders, many others are looking to expand the uses of the various types of stem cells found in bone marrow and cord blood, in particular mesenchymal stem cells, to uses beyond those that could be corrected by replacing cells in their own lineage. Early results from these trials have produced mixed results often showing minor or transitory improvements that may be attributed to extracellular factors. More research teams are accelerating the use of other types of adult stem cells, in particular neural stem cells for diseases where beneficial outcome could result from either inlineage cell replacement or extracellular factors. At the same time, the first three trials using cells derived from pluripotent cells have begun. The rapid advance of stem cell clinical trials for a broad spectrum of conditions warrants an update of the review by Trounson (2009) [1]. There has been a rapid surge in clinical trials involving stem cell therapies over the last two to three years and those trials are establishing the clinical pathways for an emergent new medicine. These early trials are showing roles for stem cells both in replacing damaged tissue as well as in providing extracellular factors that can promote endogenous cellular salvage and replenishment.
