From Matthew Stevens, Sydney, Australia
Trials of pumping cold seawater onto Arctic ice to slow its melt are a valiant attempt to counter global warming. But they are yet another example where people with knowledge and understanding of climate change are left to deal with the consequences of actions by those with far more power and money, whose short-term personal interests continue to drive the phenomenon (6 June, p 4).
Without global collaboration on urgent action to reduce carbon emissions and redress inequalities, all such projects are doomed to failure, even with the best science behind them. Unfortunately, greed is a powerful motivator, often more so than working for the collective good.
