Hypothesis About Mechanics of Global Warming from 1900 Till Now.

Authors: Belolipetsky P.V., Bartsev S.I.
Comments: 14 Pages.

We performed linear multivariate regression analysis using available estimates of natural and anthropogenic influences and the observed surface temperature records from 1900 to 2012. We considered four parts of Earth surface - tropics (30S-30N), northern middle altitudes (30N-60N), Arctic (60N-75N) and southern altitudes (60S-30S). For each part (except southern altitudes) we developed very simple linear regression models representing temperature dynamics without continuous anthropogenic influence. The monthly average tropical SST temperature anomaly dynamic could be adequately reproduced by only three factors - ENSO variability (Nino 3.4 index), volcanic aerosols in stratosphere and two climate shifts in 1925/1926 and 1987/1988 years. Northern middle altitudes SST temperature anomaly could be reproduced in general by the same factors, except ENSO which is changed on Pacific decadal oscillation (PDO) here. Continents in these parts have the same dynamic but with much more variability. Arctic temperature anomalies have in general the same dynamic as SST temperature anomalies of Atlantic ocean in northern middle altitudes (30N-60N). We didn't manage to build any adequate regression model for southern altitudes with or without anthropogenic influences, but it doesn't look like temperatures here are determined by continuous anthropogenic influence. The results enable us to suggest a quantitive hypothesis alternative to IPCC view about a mechanic of observed in past century climate change.

Time Trends for Water Levels in Lake Athabasca, Canada

Authors: Sierra Rayne, Kaya Forest
Comments: 7 Pages.

Potential time trends for water levels in Lake Athabasca, Canada, were investigated with particular emphasis on a critical examination of the available hydrometric record and other confounding factors mitigating against reliable trend detection on this sytem. Four hydrometric stations are available on Lake Athbasca, but only the Lake Athabasca near Crackingstone Point (07MC003) site has suitable - albeit temporally limited (1960-2010) - records for a rigorous time series analysis of annual water levels. The examination presented herein provides evidence that the 2010 lake level dataset at 07MC003 is flawed and should not be included in any trend analyses. With the conclusion that 2010 lake levels on Lake Athabasca at station 07MC003 are erroneous, lake level time series regressions over various timeframes between 1960 and 2009 yield widely varying degrees of non-significance and slope magnitude / direction. As a further confounding factor against mechanistic time trend analyses of water levels on Lake Athabasca, a dam and rockfill weirs were constructed on the lake outlets during the 1970s in order to maintain elevated lake levels. Thus, the entire time series of lake levels on Lake Athabasca since filling of the reservoir behind the W.A.C. Bennett Dam (Lake Williston) began in 1968 can be described as experiencing substantial anthropogenic modification. Collectively, these influences - including problems in the hydrometric record - appear to sufficiently impact the annual lake level record as to prevent reliable trend analyses that unequivocally isolate natural factors such as climate change or any other anthropogenic factors that may be operative in the source watersheds.

Evidence for Increasingly Extreme and Variable Drought Conditions in the Contiguous United States Between 1895 and 2012

Authors: Sierra Rayne, Kaya Forest
Comments: 16 Pages.

Potential annual (January-December) and summertime (June-August) regional time trends and increasingly extreme and / or variable values of Palmer-based drought indices were investigated over the contiguous United States (US) between 1895 and the present. Although there has been no significant change in the annual or summertime Palmer Drought Severity Index (PDSI), Palmer Hydrological Drought Index (PHDI), or Palmer Modified Drought Index (PMDI) for the contiguous US over this time frame, there is clear evidence of decreasing drought conditions in the eastern US (northeast, east north central, central, and southeast climate zones) and increasing drought conditions in the west climate region (California and Nevada). No significant time trends were found in the annual or summertime PDSI, PHDI, and PMDI for the spring and winter wheat belts and the cotton belt. The corn and soybean belts have significant increasing trends in both the annual and summertime PDSI, PHDI, and PMDI, indicating a tendency towards reduced drought conditions over time. Clear trends exist toward increasingly extreme (dry or wet) annual PDSI, PHDI, and PMDI values in the northeast, east north central, central, northwest, and west climate regions. The northeast, northwest, and west climate zones display significant temporal trends for increasingly extreme PDSI, PHDI, and PMDI values during the summertime. Trends toward increasingly variable annual and summertime drought index values are also apparent in the northeast, southwest, northwest, and west climate zones.

Gravitational Ejection of Earth’s Clouds

Authors: Fran De Aquino
Comments: 6 Pages.

It is shown that, under certain circumstances, the sunlight incident on Earth, or on a planet in similar conditions, can become negative the gravitational mass of water droplet clouds. Then, by means of gravitational repulsion, the clouds are ejected from the atmosphere of the planet, stopping the hydrologic cycle. Thus, the water evaporated from the planet will be progressively ejected to outerspace together with the air contained in the clouds. If the phenomenon to persist during a long time, then the water of rivers, lakes and oceans will disappear totally from the planet, and also its atmosphere will become rarefied.
