Climate science: A fistful of dust

The true effect of windblown material is only now coming to be appreciated

ON MAY 26th 2008 Germany turned red. The winds of change, though, were meteorological, not political. Unusual weather brought iron-rich dust from Africa to Europe, not only altering the colour of roofs and cars on the continent but also, according to recent calculations by Max Bangert, a graduate student at the Karlsruhe Institute of Technology, making the place about a quarter of a degree colder for as long as the dust stayed in the air.

Unusual for Germany; commonplace for the planet as a whole. The Sahara and other bone-dry places continually send dust up into the atmosphere, where it may travel thousands of kilometres and influence regional weather, the global climate and even the growth of forests halfway around the planet. …

Global climate: Tough little girl

La Nina proves as disruptive as her better-known brother

EL NINO, a periodic sloshing of warm water from west to east across the Pacific, gets its name—“the boy child”—because it is around Christmas that it warms the water off Peru. It is now understood to have far wider effects, leading to characteristic patterns of temperature, rainfall and drought around much of the world. El Nino’s female counterpart, La Nina—a cooler sloshing from east to west—is less well known, and less frequent. But it too can impose a distinctive pattern of weather worldwide.

A moderately strong La Nina began around the middle of 2010 and is now at its peak; it is very likely to last another couple of months, and conceivably into the middle of this year. It can be blamed for floods in Australia, which are typical of La Nina in their location, if not their intensity, and in the Philippines, where ten people had died as of January 4th. But these are far from the first symptoms. The torrential rains which killed hundreds in Venezuela and Colombia in November and December had the little girl’s fingerprints on them, too. The spectacular inundation in Pakistan last August also fits the pattern. …

Peat bogs and climate change: Wet, wet, wet

Forests are not the only habitat whose conservation matters to the climate

RUSSIA does not normally spring to mind as being in the forefront of the fight against climate change. The citizens of Moscow, however, need no explanation of one aspect of the problem—the importance of wetlands. Earlier this year they had an abrupt and lethal lesson on the dangers of peat-bog fires. An unusually hot summer set such fires across the country and the peatlands around Moscow generated a smog that blanketed the city with carbon monoxide and soot. By August 9th the daily death rate had climbed to 700, twice the normal level for that time of the year.

Whether peat-bog fires are being encouraged by climate change is debatable. But it is clear that they release prodigious quantities of climate-changing carbon dioxide when they happen. And even in the absence of fire, draining peatlands—for example, for agriculture—liberates a lot of carbon dioxide. In Russia such drainage is reckoned to free 160m tonnes of the gas every year. In Indonesia the figure is 508m tonnes. All told, the global total is about 1.3 billion tonnes—6% of man-made carbon-dioxide emissions even without the effect of fire. That is far more than the contribution made by aviation, for example. …

Geoengineering: Lift-off

Research into the possibility of engineering a better climate is progressing at an impressive rate—and meeting strong opposition

AS A way of saying you’ve arrived, being the subject of some carefully contrived paragraphs in the proceedings of a United Nations conference is not as dramatic as playing Wembley or holding a million-man march. But for geoengineering, those paragraphs from the recent conference of the parties to the Convention on Biological Diversity (CBD) in Nagoya, Japan, marked a definite coming of age.

Geoengineering is shorthand for the idea of fixing the problem of man-made climate change once the greenhouse gases that cause it have already been emitted into the atmosphere, rather than trying to stop those emissions happening in the first place. Ideas for such fixes include smogging up the air to reflect more sunlight back into space, sucking in excess carbon dioxide using plants or chemistry, and locking up the glaciers of the world’s ice caps so that they cannot fall into the ocean and cause sea levels to rise. …

How to Mitigate the Security Risk of Orphaned Applications

The current economic climate is forcing many organizations to cut back and consolidate, leaving many applications abandoned. Unfortunately, these orphaned applications can create cracks in security and disrupt business as the applications are not adequately assigned and managed. Here, Knowledge Center contributor Ryan C. Barnett discusses the impact of orphaned application syndrome and offers simple steps companies can take to mitigate their risk. – As today’s tumultuous economic climate forces organizations in both the private and public sectors to scale back or downsize, many programs, initiatives and even technologies have been abandoned. Similarly, the current economic environment has been rife with mergers and acquisition activity as compa…


“Favorable climate for EU integration”

Milica Delević says there is now a more favorable climate, both in the country and in the EU, for Serbia to move forward in the process of European integration. The head of the Serbian government Office for EU Integration said that the end of next year is a possible date for “gaining candidate status”, but that once “a favorable political climate starts being created, it is just a matter of time when progress will be made.”

Bacteria and climate change: Invisible carbon pumps

A group of oceanic micro-organisms just might prove a surprising ally in the fight against climate change

UNDERSTANDING how the oceans absorb carbon dioxide is crucial to understanding the role of that gas in the climate. It is rather worrying, then, that something profound may be missing from that understanding. But if Jiao Nianzhi of Xiamen University in China is right, it is. For he suggests there is a lot of carbon floating in the oceans that has not previously been noticed. It is in the form of what is known as refractory dissolved organic matter and it has been put there by a hitherto little-regarded group of creatures called aerobic anoxygenic photoheterotrophic bacteria (AAPB). If Dr Jiao is right, a whole new “sink” for carbon dioxide from the atmosphere has been discovered.

The main way that carbon dioxide is absorbed by the ocean is through photosynthesis by planktonic algae. These algae are the basis of most food chains in the sea—being eaten by tiny animals that are, in turn, eaten by larger ones. When all these creatures die, their remains (those bits that are not immediately eaten, anyway) sink to the sea floor, where some are eaten and some are buried indefinitely. These remains are known in the jargon as particulate organic matter. …

Scientist offers better ways to engineer Earth”s climate to prevent global warming

A University of Calgary climate scientist has said that there may be better ways to engineer the planet”s climate to prevent dangerous global warming than mimicking volcanoes. “Releasing engineered nano-sized disks, or sulphuric acid in a condensable vapour above the Earth, are two novel approaches. These approaches offer advantages over simply putting sulphur dioxide gas [...]

The economics of biodiversity and business

While climate scientists lament the fact that their flagship compendia, such as the IPCC reports, come under endless attack, scientists working on other environmental issues would love such high-profile pronouncements, even if they came with a similar cost. IPCC-envy was one of the rationales for the Millennium Ecosystem Assessment, published in 2005, and it is the main impetus behind the current development of an Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services. When the equally inelegantly named TEEB process (it stands for The Economics of Ecosystems and Biodiversity) was set up at the G8+5 meeting in Potsdam in 2007 its political patrons had a clear model in mind. They hoped that just as Lord Stern’s review of the economics of climate change, published in 2006, firmed resolve for action among governments and helped set in motion the processes that led to last year’s Copenhagen climate conference, so this new report should encourage a more serious global approach to the costs that damaged and dysfunctional ecosystems impose on people.

It’s worth noting that this approach implicitly assumes, as do many people, that the point of the IPCC and such endeavours is to find reasons for action, rather than dispassionately to assess the issue. Another caveat is that, as far as the climate is concerned, big and well publicised reports have manifestly not delivered the goods in terms of what UN negotiators call “environmental integrity”—producing actions that really do reduce emissions. But that does not mean that the TEEB process is either propagandistic or pointless. Treating the services provided by ecosystems as part of the economy is a good idea, and the various ways in which their value can be sustained, or even enhanced, deserve study. …
