Patient Characteristics from a Medical Cannabis Provider Medical cannabis has been prescribed by physicians to treat a variety of symptoms including pain, nausea and vomiting, anxiety, depression, and sleep disorders in patients with severe or chronic illnesses. This paper presents the baseline demographics and characteristics of patients using medical cannabis in Canada.
Paleoclimatology dates back to the 19th century, and the concept of examining varves in lake beds and tree rings to track local climatic changes was suggested in the s. This was the basis of a "schematic diagram" featured in the IPCC First Assessment Report of beside cautions that the medieval warming might not have been global.
The report discussed the difficulties with proxy data, "mainly pollen remains, lake varves and ocean sediments, insect and animal remains, glacier termini" but considered tree ring data was "not yet sufficiently easy to assess nor sufficiently integrated with indications from other data to be used in this report.
Bradley and Phil Jones composited historical records, tree rings and ice cores for the Northern Hemisphere from up to the s to produce a decadal reconstruction. It stated that, in this record, warming since the late 19th century was unprecedented. The section proposed that "The data from the last years are the most useful for determining the scales of natural climate variability".
Recent studies including the reconstruction by Hughes and Diaz questioned how widespread the Medieval Warm Period had been at any one time, thus it was not possible "to conclude that global temperatures in the Medieval Warm Period were comparable to the warm decades of the late 20th century.
In at least some areas, the recent period appears to be warmer than has been the case for a thousand or more years". The UN Conference on Environment and Development was held in Rio Angela zhang research paper Janeiro inand produced a treaty framework that called for voluntary capping of emissions at levels.
Government representatives gathered in Kyoto later during and turned this framework into a binding commitment known as the Kyoto protocol.
Bythe Clinton Administration had signed the treaty, but vigorous lobbying meant ratification of the treaty was successfully opposed in the Senate by a bipartisan coalition of economic and energy interests.
Lobbyists such as the Western Fuels Association funded scientists whose work might undermine the scientific basis of the treaty, and in it was revealed that the American Petroleum Institute had hosted informal discussions between individuals from oil companies, trade associations and conservative policy research organizations who opposed the treaty, and who had tentatively proposed an extensive plan to recruit and train scientists in media relations.
Global Change Research Programover the scientific consensus shown by the IPCC report and about the peer reviewed status of the papers it cited. He said the Science Committee had been told of this, and of comments by one IPCC reviewer that this was misleading and the text should say "Composite indicators of summer temperature show that a rapid rise occurred aroundthis rise was prior to the major greenhouse emissions.
Since then, composite temperatures have dropped slightly on a decadal scale. Fromthis was complemented by Climate Field Reconstruction CFR methods, which could show how climate patterns had developed over large spatial areas, making the reconstruction useful for investigating natural variability and long-term oscillations as well as for comparisons with patterns produced by climate models.
The CFR method made more use of climate information embedded in remote proxies, but was more dependent than CPS on assumptions that relationships between proxy indicators and large-scale climate patterns remained stable over time.
They then teamed up with Raymond S. They were able to detect that the multiple proxies were varying in a coherent oscillatory way, indicating both the multidecadal pattern in the North Atlantic and a longer-term oscillation of roughly years in the surrounding region.
Their study did not calibrate these proxy patterns against a quantitative temperature scale, and a new statistical approach was needed to find how they related to surface temperatures in order to reconstruct past temperature patterns. Hughes to develop a new statistical approach to reconstruct underlying spatial patterns of temperature variation combining diverse datasets of proxy information covering different periods across the globe, including a rich resource of tree ring networks for some areas and sparser proxies such as lake sediments, ice cores and corals, as well as some historical records.
Their method was based on separate multiple regressions between each proxy record or summary and all of the leading principal components of the instrumental record.
The least squares simultaneous solution of these multiple regressions used covariance between the proxy records. The results were then used to reconstruct large-scale patterns over time in the spatial field of interest defined as the empirical orthogonal functionsor EOFs using both local relationships of the proxies to climate and distant climate teleconnections.JNN is a multidisciplinary peer-reviewed journal covering fundamental and applied research in all disciplines of science, engineering and medicine.

Social media in Europe: Lessons from an online survey. In the hockey stick controversy, the data and methods used in reconstructions of the temperature record of the past years have been disputed.
Reconstructions have consistently shown that the rise in the instrumental temperature record of the past years is not matched in earlier centuries, and the name "hockey stick graph" was coined for figures showing a long-term decline followed by.
