Book Description
"In this report, monthly mean sea level (MSL) variations are analyzed for 117 stations of the National Ocean Service's (NOS) National Water Level Observation Network (NWLON) having between 25 and 146 years of data. Monthly MSL data up to the end of 1999 are used to calculate linear trends, and to obtain the average seasonal cycle, the residual time series, and the autoregressive coefficient of the residual with accurate estimates of standard errors. Months with extreme high or low residuals are defined and periods of broad regional correlations between station anomalies are observed. Since the derived trends include the local vertical land motion, they are spatially variable. Calculated MSL trends range from 9.85 mm/yr for Grand Isle, LA to -16.68 mm/yr for Skagway, AK and are consistent with previous station trends published by NOS. The appendices of this report include time series plots for each station of the monthly MSL with the seasonal cycle removed, the seasonal cycle, and the MSL residual after both the seasonal cycle and the trend are removed. The location and timing of any major earthquakes near stations in tectonically-active areas are noted, since an associated vertical offset or a change in MSL trend is possible. An inverse power relationship is derived empirically, relating the standard error for linear trends to the year range of MSL data. An estimated 50 to 60 years of data are required for obtaining linear MSL trends having a 1 mm/yr precision with a 95% statistical confidence interval. For a given length of data, the standard errors for trends at Pacific Ocean and western Gulf of Mexico stations tend to be greater than standard errors for trends at Atlantic coastal stations. MSL trends for the most recent 50-year period of 1950-1999 are compared with trends obtained from each station's entire data set. The trend for the past 50 years is significantly lower at only three out of sixty stations (Eastport, Portland, and Boston). At no station is the 1950-1999 trend significantly higher than the trend obtained from the station's entire data set. In an examination of 50-year MSL trends at sixteen of the longest term stations, it was found that for six Atlantic stations, the periods centered on years from 1930 to 1955 tend to have significantly higher trends than periods centered on years from 1965 to 1975. For San Francisco, trends for all 50-year periods centered from 1890 to 1915 are significantly lower than the overall trend and the trend since the 1906 San Francisco earthquake"--Executive Summary.

Book Description
This book brings together a wealth of scientific findings andecological knowledge to survey what we have learned about the“Wet Tropics” rainforests of North Queensland,Australia. This interdisciplinary text is the first book to providesuch a holistic view of any tropical forest environment, includingthe social and economic dimensions. The most thorough assessment of a tropical forest landscape todate Explores significant scientific breakthroughs in areasincluding conservation genetics, vegetation modeling, agroforestryand revegetation techniques, biodiversity assessment and modeling,impacts of climate change, and the integration of science innatural resource management Research achieved, in part, due to the Cooperative ResearchCentre for Tropical Rainforest Ecology and Management (theRainforest CRC) Written by a number of distinguished internationalexperts contains chapter summaries and section commentaries

Book Description
Consideration of climate change deals increasingly with impacts and responses, and therefore involves a wide range of technical issues and a diverse community of experts. One of the challenges faced is that of ensuring effective communication between these different areas of expertise. For example, climate change studies require new types of collaboration between carbon cycle modellers and economists, and between meteorologists and coastal geomorphologists. Furthermore, there is a need to distil balanced assessments ranging across many disciplines for the benefit of all policymakers.Greenhouse: Coping with Climate Change brings together the contributions of many experts to the climate change debate. This book is a landmark publication summarising our understanding of climate change issues as they affect Oceania. It contains review papers that report on the status of knowledge, methodologies and developments; and a selection of focused papers that expand on specific issues and present significant new developments of wide general interest and relevance to the region.
