According to a new analysis by scientists at the National Center for Atmospheric Research (NCAR) in the USA the percentage of Earth's land area stricken by serious drought more than doubled from the 1970s to the early 2000s. Iguo Dai, lead author of the study, said that rising global temperatures appear to be a major factor. Widespread drying occurred over much of Europe and Asia, Canada, western and southern Africa, and eastern Australia.

Climate Change and Development Issues for Island States

From 10-14 January civil society organisations and leaders of 37 small island states met in Port Louis, Mauritius. High on the agenda are discussions on an early warning system in the Indian Ocean to protect against tsunamis. Also on the agenda is the issue of rising sea levels, widely attributed to global warming. The decreasing levels of aid and Western trade barriers are also common issues.

Rising Sea Levels and Climate Change

A few months ago, four major hurricanes and tropical storms – Charley, Frances, Ivan and Jeanne – struck the Caribbean islands (and southeastern United States), causing thousands of casualties in Haiti and devasting Grenada. This worst Caribbean hurricane season in living memory, along with other extreme weather events that took place in 2004 in both the Pacific and Indian Oceans, are seen by many as empirical evidence of impacts that are harbingers of the expected effects of climate change.

Sea levels are currently rising at about two millimetres a year, but there are sign this rate may be increasing. Rising seas could swamp countries like the Maldives and Tuvalu. While the fate of small island nations is at risk, developed countries also stand to lose. Many cities around the world are located near coasts. Flooding from rising sea levels could cause massive damage to infrastructure.

Mike MacCracken, chief scientist for climate change programmes at the Climate Institute, a Washington think-tank, said "It's often presented as a problem only for developing nations. (But) developed countries will be very much at risk because so much infrastructure is at sea level."

Flood Barriers proposal for London

The city of London is already considering proposals for a ten-mile barrier across the River Thames to prevent it flooding. Scientists believe without such a barrier Westminster may be inundated in 6 feet of flood water. Jim Hall, of the Tyndall Centre for Climate Change Research, an author of the proposals, said: "We wanted to look at the more extreme but still plausible scenarios for sea level rise. The chances of these happening are small but the consequences are so dramatic that we have to prepare for them."

The proposal is for a vast embankment, from Sheerness in Kent to Southend on the other side of the estuary in Essex. The barrier would contain gates to allow water to flow in and out of the Thames Estuary according to the tides. But the gates would be shut if a flood seemed likely.

Coastal areas like the east coast of North America and particularly Florida are vulnerable to rising sea levels. A Satellite photo from NASA/JPL gives a dramatic demonstration of how Florida's low topography, especially along the coastline, make it especially vulnerable to flooding associated with storm surges.

The International Panel on Climate Change (IPCC) indicated that the global average sea level has risen by 10 to 20 cm over the past 100 years. This represents a rate of increase of 1 to 2 mm per year, i.e. some 10 times faster than the rate observed for the previous 3,000 years. It also projected a global average temperature increase of 1.4-5.8°C, and a consequential rise in global mean sea level of 9-88 cm, by the year 2100.

Flooding could cause billions of dollars of damage around the world. In Bangladesh, 17 million people live less than one metre (three feet) above sea level.

Tuvalu inundated by King Tides

In February 2004, the nine islands of the low-lying atoll of Tuvalu were submerged by "king tides" with peaks approaching three metres. These tides washed over the lowest points of that nation, whose highest point is only 4.5 metres (15 feet) above sea level, affecting freshwater sources and damaging food crops. According to its inhabitants, such king tides, once rare for the islands, now occur roughly every two years. The worst flooding happened in 2001, when practically all the entire land area of these islands was under water.

Small Island Developing States (SIDS) meet

In Mauritius on January 10, civil society groups called for greater action from the international community to address the special needs of Small Island Developing States (SIDS). Advocacy groups raised concern over the lack of progress in the implementation of the Barbados Programme of Action (BPoA), agreed at the first such conference a decade ago. Aid to 45 states has fallen by more than half in eight years, leaving them increasingly vulnerable to external shocks.

Coordinator of the Civil Society Forum, Pynee Chellapermal, told journalists the calamity that had befallen Asia in December was an "eye-opener" for the international community to the "fragility" of small island countries, and it was "critical" that donors pledged their support to the development of an early warning system. But other concerns were also stressed including the "dearth of resources, poor human and institutional capacity" and the "lack of technology transfer" were also to blame for chronic underdevelopment.

"Our environmental concerns have a lot to do with poverty: for example, the lack of fresh water doesn't have anything to do with the quantity of rain we receive annually - we just do not have the resources to harness the rain when it does fall," said Mohammend Amidou, president of the Comoran Association for Environmental Development. In some parts of the Comoros archipelgo less that 10 percent of the population had access to safe drinking water.

International Meeting

At the formal International Meeting of SIDS environmental vulnerabilities were discussed. Delegates focused on: early warning systems; destruction of coral reefs and mangrove forests; concerns with linking climate change and extreme events; provision of financial resources for early warning; GEF’s role in renewable energy projects in SIDS; capacity building; pre-disaster action; climate mitigation; information and education; earth observation technologies; climate monitoring networks and systems; international cooperation; socioeconomic impacts of climate change; partnerships; and sharing of new technologies.

Trade and Development are also major topics of discussion. Representatives from several Small Island Developing States (SIDS) highlighted that over the past decade trade liberalisation had severely battered their fragile economies. Participants appealed for "special" treatment for their exports, which would compensate for the high economic costs resulting from their remoteness and smallness.

Grassroots discussions and workshops

Alongside the United Nations sponsored meeting of leaders there were more grassroots events: the Community Vilaj and Civil Society Forum (6-9 January 2005). The latter, organized to establish the accomplishments and shortcomings of the Barbados Program of Action of 1994, saw the participation of 2,000 delegates from all over the world, including 25 heads of State. There has been some criticism that accomplishment of the objectives of the civil society forum has been hindered by a lack of consensus and optimization of resources.

The Community Vilaj, which goes by the motto, "Local voices, global impact", regroups people who have reduced poverty with ecofriendly projects in their towns or villages. The United Nations Development Program (UNDP), has enabled many to attend to maintain continuity of their projects through the exchange of ideas and experience on a wide range of environmental and social subjects.

There is also an Island Innovations Fair on Resilience Building Technologies and an Institute@SIDS, which is a joint initiative of the UNDP and the Smithsonian Institution, offering free training courses to Vilaj’s participants.

The Innovations Fair exhibits sustainable development technologies that "directly address specific economic and environmental vulnerabilities of SIDS". An example of such innovative technology is the Uehara Cycle presented by the Institute of Ocean Energy of Japan’s Saga University. The Uehara Cycle, which uses Ocean Thermal Energy Conversion (OTEC) to convert the temperature difference between the warm surface seawater and the cooler water at a depth of 800 metres into electricity, is seen as a solution to both the precariousness of energy supplies on islands and global warming.

2004 the Fourth Warmest Year Globally

The World Meteorological Organization (WMO) has determined that 2004 was the fourth warmest year since accurate records commenced in 1861. The last 10 years (1995-2004), with the exception of 1996, are among the warmest 10 years on record.

Droughts swept Africa, India and Australia and contributed to record forest fires in Alaska. The global mean surface temperature in 2004 is expected to reach 0.44 degrees celsius above the 1961-1990 annual average of 14 degrees, with October the warmest October ever recorded.

"The series of warm years is continuing," Soobasschandra Chacowry, a director at the WMO, told journalists.

USA continues to obstruct Climate talks

Another round of Climate talks have ended in Buenos Aires, with the USA continuing to obstruct talks. Greenpeace expressed disappointment at the outcome of the climate talks in Buenos Aires, and anger at the USA and Saudi Arabia for their deliberate tactics of obstruction and delay. The agreement means that discussions on future greenhouse gas cuts will not progress substantially during the coming year and will not ensure that countries most at risk from climate impacts get the assistance they need from the industrialised world.

Greenpeace spokeperson, Steve Sawyer said "We hope that everyone has taken note of the bullying and blocking tactics of the USA at these negotiations. As a result we have a deal that barely keeps the process moving. This agreement ensures that there will not be the kind of progress we need on negotiations of future emissions cuts during the next twelve months, and the adaptation package is far from adequate."

CSIRO warns: Australia to get hotter, wetter, with more extreme weather

Recent research by CSIRO and Bureau of Meteorology scientists puts forward that climate change is a reality in Australia and is set to make the Australian climate much warmer, wetter, with more extreme weather events. While average rain across the continent has increased over the last 50 years, certain areas such as south west Australian and parts of Eastern Australia may actually be much drier.

Average temperatures are set to rise, with the possibility that some inland towns may become inhabitable. Bush fires, droughts, storms and flooding will have increasing impact on social and economic infrastructure. The overwhelming consensus amoung scientists is that such climate change has been brought about through global warming caused to a large extent by greenhouse gases such as carbon dioxide produced by humans.

Escalating global species extinction crisis

Repost of World Conservation Union media release

A total of 15,589 species face extinction, reveals the 2004 IUCN Red List of Threatened Species. One in three amphibians and almost half of all freshwater turtles are threatened, on top of the one in eight birds and one in four mammals known to be in jeopardy.

Bangkok , Thailand , 17 November 2004 (IUCN) – From the mighty shark to the humble frog, the world’s biodiversity is declining at unprecedented rates.Halting the growing extinction crisis will be a major concern for IUCN’s 1,000 plus member organizations attending the 3 rd IUCN World Conservation Congress, which kicks off in Bangkok today.

The situation facing global biodiversity is clearly escalating and the 4,000 delegates, including representatives of the private sector, governmental and non-governmental organisations, will be outlining ways to halt this alarming trend. They will draw the attention of the international community to the fact that species loss has critical implications for human wellbeing, and that conserving biodiversity is central to managing the risks this poses to sustainable development.

Polar Regions experiencing severe climate change

The Arctic and Antarctic are experiencing severe climate change. The Arctic ice cap is melting at an unprecedented rate due to human induced global warming, according to a new study conducted by 300 scientists and elders from native communities in the arctic, released 8 November. Over the last 30 years the ice cap has shrunk 15-20 per cent. In 2003 the Ward Hunt Ice Shelf, the largest in the Arctic, broke into two pieces. With the build up of greenhouse gases, primarily carbon dioxide, the trend is set to accelerate with forecasts that by the summer of 2070 there maybe no ice at all.

Warming In Antarctica: cause for concern

In Antarctica the ocean food chain is crashing due to the loss of ice shelves around the Antarctic peninsula caused by climate warming. The breakup of the Larsen B ice shelf in 2002 has also released several glaciers, increasing their speed eight fold, and dumping their loads into the Weddell Sea contributing to a rising sea level, according to new research.

Carbon Dioxide Emissions cause Arctic to Melt, Sea Levels to Rise

The Arctic ice cap is melting at an unprecedented rate due to human induced global warming, according to a new study conducted by 300 scientists and elders from native communities in the arctic. Over the last 30 years the ice cap has shrunk 15-20 per cent. With the build up of greenhouse gases, primarily carbon dioxide, the trend is set to accelerate with forecasts that by the summer of 2070 there maybe no ice at all.

The report said that the Arctic "is now experiencing some of the most rapid and severe climate change on Earth", Further: "Over the next 100 years climate change is expected to accelerate, contributing to major physical, ecological, social and economic changes, many of which have already begun."

Kyoto is not enough says UK Chief Scientist, while Australia sticks with the USA

The United Kingdom (UK) government's chief scientist, Sir David King, has warned that climate change is the most serious issue facing the world this century. He was speaking at a recent Greenpeace Business conference in London - "we are seeing extreme events which are attributable to global warming, at least in part, and these are having quite devastating effects." Australia and the USA are refusing to ratify the climate treaty.

"Kyoto is not enough. Kyoto is a beginning and it’s a good process. And what will be needed is once we’ve got the process up and running, it will need to be ratcheted up so that we can really bring emissions under control. The key problem, of course, is going to be moving into the second period, when we need to bring on board not only Australia and the United States, but also the big growing economies, China and India."

The Howard Government has refused to ratify the Kyoto Protocol. The USA and Australia are the only two western industrialised nations (1) who have refused to ratify the Protocol. Greenpeace Australia said that the Howard Government should commit to a target and road map to reduce greenhouse pollution by at least 60 percent by 2050 so that Australia will be protected from climate change.

A Greenpeace statement said: "Australia is the most vulnerable developed country to the impacts of climate change. Without significant reductions in our greenhouse pollution, we face more frequent and severe droughts and bushfires, annual coral bleaching on the Great Barrier Reef, the potential loss of Australia's ski fields and serious damage to other important ecosystems such as the Wet Tropics."

According to the Greenpeace statement, opinion polls commissioned by Greenpeace and others consistently show that at least 75% of Australians want the Government to ratify Kyoto, irrespective of the US position.

"Once Kyoto is in place, the world will have to face the challenge of the at least 60% emissions reductions that scientists tell us are necessary," said Greenpeace Campaigns Manager Danny Kennedy. "In Australia, we must see mandated emissions reductions and clean energy targets to get us there."

"But first Mr Howard must respond to the weight of public opinion, the necessities of global business and increasing extreme weather by immediately ratifying the Kyoto Protocol and joining the international effort to tackle climate change, the greatest challenge of our age." said Kennedy.

On October 22 the Russian parliament approved the ratification of the Kyoto Protocol (FOE Europe). Once approved by the upper house and President Vladimir Putin, the treaty will come into force as international law 90 days later.

Note 1: Croatia, Liechtenstein and Monaco (all with neglible emissions) - have not yet ratified the Kyoto Protocol, only Australia and the US have said that they will not ratify. The other three are all expected to do so. A full list of countries and their ratification status (PDF) is available.
