Despite the announcement that air space could begin to re-open in Northern Europe, the Icelandic volcano eruption could prove to be a major turning point for the global airline industry with short- to medium-term questions already being asked by some about its future financial viability.
One of the biggest questions, which engineers will be grappling with right now, is whether there is a cost-efficient way to ‘design out’ the current problems that aircraft experience with dust clouds.
The short answer is that it may be possible to make modifications to aircraft engine cores to make them less sensitive to ash deposits. However, such major engine development is a long term project so no solution will be in sight for at least a year. Moreover, the expense of such an undertaking could be prohibitively costly for airlines right now.

The unprecedented no-fly zone currently in force across much of Europe has already caused the greatest chaos to air travel since the Second World War. Thousands of flights have been cancelled or postponed with millions of travel plans affected.

Efforts to implement cap-and-trade programs at state level are faltering, just as policymakers in Washington are struggling to generate enough support to put in place a comprehensive national system.
Recent setbacks in California and Arizona point to growing headwinds against the policy. As cap-and-trade loses momentum and becomes embroiled in bigger political disputes about the size and role of government, opponents are becoming emboldened to try to block the policy completely.

The international observance of World Water Day, this year on March 22, is an initiative that grew out of the 1992 United Nations Conference on Environment and Development in Rio de Janeiro. This year’s theme — ‘Clean Water for a Healthy World’ — reflects the fact that population and industrial growth are adding new sources of pollution and increased demand for clean water across the world.

We live surrounded by uncertainty. Tsunamis, the eruption of super- volcanoes, violent floods and storms, asteroid impacts that eliminate entire species as the dinosaurs that went extinct 60 millions years ago, the recent 8.8 earthquake in Chile, not to mention the global financial crisis. Some disasters are worse than others, but they all have one thing in common. They are catastrophic risks. This means risks that occur very rarely – but when they happen they have truly major consequences.

It’s as though three mammoth challenges facing America are intertwined like the strands of a rope: reducing our dependence on Mideast oil; creating new American jobs from clean energy; and reducing pollution responsible for climate change.

While attending a meeting of prominent climate sceptics during the U.N. Climate Conference in Copenhagen in December (an anti-COP15, if you will), I listened to each of the speakers put forward their theory on why conventional evidence on the primary causes of climate change should be dismissed as, for lack of a better phrase, complete hokum.
Among their denunciations of widely-accepted truths regarding global warming, greenhouse gases, melting glaciers and rising sea levels was the assertion that a change in attitude was afoot; the public may have been duped into believing the mainstream scientific assessment of climate change, but not for long.

Uncertainty about the future cost of emissions allowances for greenhouse gases is one of the biggest obstacles to winning consent for a cap and trade or cap and refund programme in the U.S. Congress. To have any realistic prospect of passing emissions legislation, lawmakers must find a way to reduce it.
Proponents argue a trading programme would ensure emissions reductions are achieved in the most cost-effective manner. They point to the success of the Environmental Protection Agency (EPA)'s Acid Rain Program in cutting sulphur dioxide (SO2) emissions much more quickly and at a fraction of the expected costs during the 1990s.
Title IV of the Clean Air Act Amendments (CAAA) 1990 established a trading programme for SO2 emissions from power plants. Phase I, beginning in 1995, covered the 110 dirtiest coal-fired electricity generating facilities.

Today the global megatrends of food security, energy security, global climate change and sustainability command the attention of nations worldwide. Confronting these challenges will test political systems, drive policy and stress international relations.
Pope Benedict on Tuesday linked the Roman Catholic Church's opposition to gay marriage to concern about the environment, suggesting that laws undermining the differences between the sexes were threats to creation.
Creatures differ from one another and can be protected, or endangered, in different ways, as we know from daily experience. One such attack comes from laws or proposals which, in the name of fighting discrimination, strike at the biological basis of the difference between the sexes," he said at his annual meeting at the Vatican with ambassadors to the Holy See.
