Climate change and trace gases Hansen et al. 2007
"Palaeoclimate data show that the Earth's climate is remarkably sensitive to global forcings. Positive feedbacks predominate. This allows the entire planet to be whipsawed between climate states. One feedback, the property of ice/water, provides a powerful trigger mechanism. A climate forcing that the albedo of a suficient portion of an ice sheet can spark a cataclysm. Inertia of ice sheet and ocean provides only moderate delay to ice sheet disintegration and a burst of added global warming. Recent greenhouse gas (GHG) emissions place the Earth perilously close to dramatic climate change that could run out of our control, with great dangers for humans and other creatures. Carbon dioxide (CO2) is the largest human-made climate forcing, but other trace constituents are also important. Only intense simultaneous efforts to slow CO2 emissions and reduce non-CO2 forcings can keep climate within or near the range of the past million years. The most important of the non-CO2 forcings is methane (CH4), as it causes the second largest human-made GHG climate forcing and is the principal cause of increased tropospheric ozone (O3), which is the third largest GHG forcing. Nitrous oxide (N2O) should also be a focus of climate mitigation efforts. Black carbon (Ôblack sootÕ) has a high global warming potential (approx. 2000, 500 and 200 for 20, 100 and 500 years, respectively) and deserves greater attention. Some forcings are especially effective at high latitudes, so concerted efforts to reduce their emissions could preserve Arctic ice, while also having major bene¥ts for human health, agricultural productivity and the global environment"

Last Glacial Maximum ocean thermohaline circulation: PMIP2 model intercomparisons and data constraints
"The ocean thermohaline circulation is important for transports of heat and the carbon cycle. We present results from PMIP2 coupled atmosphere-ocean simulations with four climate models that are also being used for future assessments. These models give very different glacial thermohaline circulations even with comparable circulations for present. An integrated approach using results from these simulations for Last Glacial Maximum (LGM) with proxies of the state of the glacial surface and deep Atlantic supports the interpretation from nutrient tracers that the boundary between North Atlantic Deep Water and Antarctic Bottom Water was much shallower during this period. There is less constraint from this integrated reconstruction regarding the strength of the LGM North Atlantic overturning circulation, although together they suggest that it was neither appreciably stronger nor weaker than modern. Two model simulations identify a role for sea ice in both hemispheres in driving the ocean response to glacial forcing"

England under water: scientists confirm global warming link to increased rain
By Michael McCarthy Environment Editor
Published: 23 July 2007
It's official: the heavier rainfall in Britain is being caused by climate change, a major new scientific study will reveal this week, as the country reels from summer downpours of unprecedented ferocity.

More intense rainstorms across parts of the northern hemisphere are being generated by man-made global warming, the study has established for the first time _ an effect which has long been predicted but never before proved.

Heatwave claims hundreds of lives in Europe

Published: Tuesday July 24, 2007

Up to 500 people have died in a heatwave in the past week in Hungary, the country's chief medical officer said Tuesday as Europe struggled to cope with extreme weather conditions.

Soaring temperatures across southern and eastern Europe claimed scores of lives, including in southern Italy where a wildfire Tuesday burned two people alive in their car and suffocated another two when it spread to a beach nearby.


At the same time, Britain struggled to cope with the worst flooding for 60 years, which has seen some towns turned into islands and hundreds of thousands of homes left without power or running water.

Hungary's chief medical officer Ferenc Falus said that during last week from July 15 to July 22 the heat in central Hungary "contributed to the early death of 230 people, which nationally means about 500 deaths".

The country has been on its highest ever alert for a week, with temperatures hitting the all-time high of 41.9 degrees Celsius (107.4 degrees Fahrenheit) in the southern city of Kiskunhalas.

In the Balkans authorities meanwhile warned people to stay indoors to avoid searing temperatures that have already killed 30 people in Romania and two in Bulgaria and Greece, with another two deaths reported in Croatia.

Temperatures in the region rose to 40 degrees Celsius and above, with Greece experiencing 45 degrees on Tuesday and Italy a high of 44. Rome recorded one of its warmest nights ever Monday at 27.1 degrees.

Bulgaria sweltered in its hottest temperatures since records began with the mercury shooting above 45 degrees Celsius in parts of the country, and more than 860 people were reported to have fainted in the streets in Romania.

The heat also fanned several fires, with one of the most serious on Tuesday raging near the southern Macedonian city of Bitola.

One person died and thousands were evacuated as the blaze lay waste to some 1,000 hectares (2,500 acres) of forest near Macedonia's second-largest city.

The Italian wildfires that claimed four lives Tuesday near the town of Peschici, in southern Puglia region, prompted the defence minister to send in the military to help.

Four campsites were destroyed and about 4,000 people were evacuated by sea from the beach at Peschici because of the blaze, the coastguard said.

Greece was also recovering from a season of blazes that in the past month have devastated 32,000 hectares, according to the government.

One of the larger fires destroyed 5,600 hectares of forest on Mount Parnitha overlooking Athens, including more than a third of a national park that was supposedly among Greece's best protected areas.

The country took another blow on Monday when a water-bomber plane crashed while fighting a blaze on the island of Evia, killing both pilots.

The accident heightened concerns that Greece's fire-fighting resources have been stretched to the breaking-point, with Greek water-bomber pilots logging nearly 2,000 hours of missions since June, the air force said.

Forest fires also raged on the Adriatic coast with Croatia and Serbia each facing more than a dozen blazes.

Meanwhile, Britain was longing for drier weather as the fate of many English cities, towns and villages hung in the balance and emergency crews built up defences against rising waters.

Large swathes of central and western England have been submerged for days and at least 350,000 homes have been left without running water and 50,000 without power, although supplies were now being restored.

The government's crisis response committee, Cobra, met late Monday and again on Tuesday as some rivers topped levels reached during the floods in 1947, even as meteorologists forecast more rain.

A spokesman for Prime Minister Gordon Brown, who chaired the latest crisis meeting, defended the government's actions amid charges it had been too slow to prepare for floods even though heavy rains had been forecast since last week.

Rise in Sea Levels May See Coastal Communities Abandoned
"With the rising sea levels that are predicted and increasing tidal surges we cannot guarantee that the coastline will be where it is at the moment and we as a society need to start thinking about how best to look after people"

Indirect radiative forcing of climate change through ozone effects on the land-carbon sink
"The evolution of the Earth's climate over the twenty-first century depends on the rate at which anthropogenic carbon dioxide emissions are removed from the atmosphere by the ocean and land carbon cycles. Coupled climate–carbon cycle models suggest that global warming will act to limit the land-carbon sink, but these first generation models neglected the impacts of changing atmospheric chemistry. Emissions associated with fossil fuel and biomass burning have acted to approximately double the global mean tropospheric ozone concentration, and further increases are expected over the twenty-first century. Tropospheric ozone is known to damage plants, reducing plant primary productivity and crop yields, yet increasing atmospheric carbon dioxide concentrations are thought to stimulate plant primary productivity. Increased carbon dioxide and ozone levels can both lead to stomatal closure, which reduces the uptake of either gas, and in turn limits the damaging effect of ozone and the carbon dioxide fertilization of photosynthesis. Here we estimate the impact of projected changes in ozone levels on the land-carbon sink, using a global land carbon cycle model modified to include the effect of ozone deposition on photosynthesis and to account for interactions between ozone and carbon dioxide through stomatal closure. For a range of sensitivity parameters based on manipulative field experiments, we find a significant suppression of the global land-carbon sink as increases in ozone concentrations affect plant productivity. In consequence, more carbon dioxide accumulates in the atmosphere. We suggest that the resulting indirect radiative forcing by ozone effects on plants could contribute more to global warming than the direct radiative forcing due to tropospheric ozone increases"

From Janus' link above:

"This summer has certainly been unusual. A persistent kink in the jet stream has delivered a near-constant flow of Atlantic depressions to the British Isles, driving them much further south than normal. Our 20 July downpour was something of a "perfect storm", a slow-moving front bringing warm, moist air from Europe into contact with a cooler air mass from the west"

Effects of Mount Pinatubo volcanic eruption on the hydrological cycle as an analog of geoengineering
"The problem of global warming arises from the buildup of greenhouse gases such as carbon dioxide from burning of fossil fuels and other human activities that change the composition of the atmosphere and alter outgoing longwave radiation (OLR). One geoengineering solution being proposed is to reduce the incoming sunshine by emulating a volcanic eruption. In between the incoming solar radiation and the OLR is the entire weather and climate system and the hydrological cycle. The precipitation and streamflow records from 1950 to 2004 are examined for the effects of volcanic eruptions from El Chichón in March 1982 and Pinatubo in June 1991, taking into account changes from El Niño-Southern Oscillation. Following the eruption of Mount Pinatubo in June 1991 there was a substantial decrease in precipitation over land and a record decrease in runoff and river discharge into the ocean from October 1991–September 1992. The results suggest that major adverse effects, including drought, could arise from geoengineering solutions"
http://www.agu.org/pubs/crossref/2007/2 ... 0524.shtml

The catastrophe that time forgot
"Like a shockwave following a nuclear blast, the volcanic dust spread from Iceland over continental Europe and affected worldwide temperature by almost one degree Celsius. According to Charles A. Wood in his article "Climactic Effects of the 1783 Eruption," this resulted in reports of drought in China, famine in India, crop destruction in Scotland, and even tulips dying in Holland. There were near record depths of snow, and ice floes appeared in the Gulf of Mexico. The Mississippi froze just outside of New Orleans, and there were near record cold temperatures noted throughout the United States"

The eastern EIO had cold sea surface temperature anomalies (SSTA), lower sea level, shallow thermocline and higher chlorophyll than normal. The anomalies in the east, restricted to the south of the equator, were highest off Sumatra. The western pole of the IOD was marked by warm SSTA and deeper thermocline with maxima on either side of the equator"

Pulse of the seafloor: Tidal triggering of microearthquakes at 9°50?N East Pacific Rise
"Due to the proximity of this site to an ocean tidal node, where changes in sea surface height are minimal, periodic stress changes are dominated by the solid Earth tide. In contrast, previous studies on the Juan de Fuca Ridge have shown microearthquake triggering to be a response to seafloor unloading during times of low ocean tide"
