Climate change: fast out of the gate, slow to the finish

Washington, D.C.— A great deal of research has focused on the amount of global warming resulting from increased greenhouse gas concentrations. But there has been relatively little study of the pace of the change following these increases. A new study by Carnegie’s Ken Caldeira and Nathan Myhrvold of Intellectual Ventures concludes that about half of the warming occurs within the first 10 years after an instantaneous step increase in atmospheric CO2 concentration, but about one-quarter of the warming occurs more than a century after the step increase. Their work is published in Environmental Research Letters.

The study was the result of an unusual collaboration of a climate scientist, Ken Caldeira, who contributed to the recently published Intergovernmental Panel on Climate Change report, and Nathan Myhrvold, the founder and CEO of a technology corporation, Intellectual Ventures LLC. It is the third paper on which they have collaborated. (more…)

30 Umweltschützern drohen bis zu 15 Jahre Haft

Hamburg, 4. 10. 2013 – In 30 Städten protestieren am morgigen Samstag Greenpeace-Aktivisten für die Freilassung ihrer in Russland inhaftierten Kollegen. Die 28 Aktivisten und zwei Journalisten befinden sich in russischer Untersuchungshaft und sind von einem Gericht in Murmansk wegen bandenmäßiger Piraterie angeklagt. Bei einer Verurteilung drohen ihnen bis zu 15 Jahre Haft.

Die Umweltschützer hatten gegen Ölbohrungen des russischen Ölkonzerns Gazprom in der Arktis protestiert. Einen Tag danach war das Greenpeace-Aktionsschiff „Arctic Sunrise“ von der Küstenwache in internationalen Gewässern geentert und nach Murmansk geschleppt worden. (more…)

While U.S President Barack Obama blames House Speaker John Boehner for the Federal Government Shutdown, it already started to hit at the cores of scientific developments in America. Today we noticed that the website of USGS (U.S Geological Survey) whose logo says ‘Science for a changing World’ is unavailable.

It reads ‘Due to the Federal government shutdown, usgs.gov and most associated web sites are unavailable.’ (more…)

Legacy Soil Pollution: Higher lead levels may lie just below surface

A study of data from hundreds of soil samples taken around six old water tower sites in southern Rhode Island finds that even when lead levels on the surface are low, concentrations can sometimes be greater at depths down to a foot. The findings inform efforts to assess the effect of lead paint from old water towers on surrounding properties.

PROVIDENCE, R.I. [Brown University] — A newly published analysis of data from hundreds of soil samples from 31 properties around southern Rhode Island finds that the lead concentration in soil at the surface is not always a reliable indicator of the contamination a foot deeper. The study, led by Brown University Superfund Research Program researchers at the request of the Rhode Island Department of Health (RIDOH), informs ongoing efforts to assess the impact of the state’s legacy of lead-painted water towers.

Rekordtemperaturen und Überschwemmungen – Superlative in immer kürzeren Intervallen. Und der Mensch hat das zum größten Teil selbst zu verantworten.

Die Fakten sprechen eine deutliche Sprache: Die Erde erwärmt sich weiterhin in einem rasanten Tempo und die Meeresspiegel steigen stärker an als bisher prognostiziert. Das besagt der jüngste Report des sogenannten Zwischenstaatlichen Ausschusses für Klimaänderungen (IPCC – Intergovernmental Panel on Climate Change), der am Freitag, dem 27. September in Stockholm veröffentlicht wurde. (more…)

Establishing World-Class Coral Reef Ecosystem Monitoring in Okinawa

Enduring two typhoons over a three-week period in August, Woods Hole Oceanographic Institution (WHOI) researchers, working in partnership with the Okinawa Institute of Science and Technology Graduate University (OIST), have successfully deployed an OceanCube Observatory System in waters off Motobu Peninsula, Japan — a biodiversity hotspot that is home to ecologically significant coral reefs. The observatory system enables real-time monitoring of temperature, salinity, and other chemical, biological and physical data critical to understanding the health of and changes in the coral reef ecosystem.

Okinawa is situated at the northernmost end of the border between the Pacific and the Indian Oceans. The coral reefs there support the highest diversity of endemic species, plants and animals in the world. These coral reefs are also economically valuable, generating as much as 3 trillion yen ($30 billion) globally, and 250 billion yen ($2.5 billion) in Japan. (more…)

Der vom Menschen gemachte Klimawandel hat stärkere Auswirkungen auf die Weltmeere als bislang bekannt. Dies geht aus den heute in Stockholm vorgestellten Ergebnissen des Klimabericht des IPCC (Intergovernmental Panel of Climate Change) hervor. Die vom Menschen verursachten CO2-Emissionen wirken direkt auf die Ozeane: Die Meere werden saurer, weil das Meerwasser CO2 aus der Atmosphäre aufnimmt und sich daraus Kohlensäure bildet. (more…)

Berkeley Lab Climate Scientists See Better Climate Models, Warmer Future

Berkeley Lab experts contribute to IPCC 5th Assessment Report.

Over the next century, most of the continents are on track to become considerably warmer, with more hot extremes and fewer cold extremes. Precipitation will increase in some parts of the world but will decrease in other parts. These are some of the conclusions reached by Lawrence Berkeley National Laboratory (Berkeley Lab) scientist Michael Wehner and his co-authors on the Fifth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC).

Wehner, a climate scientist in Berkeley Lab’s Computational Research Division, and William Collins, head of the Lab’s Climate Sciences Department, were lead authors on the IPCC report’s chapters on long-term climate change projections and climate models, respectively. They are among more than 200 lead authors from more than 30 countries in IPCC’s Working Group I. Their report released today provides a comprehensive assessment of the physical science basis of climate change. (more…)
