Time is running out for Australia’s iconic Great Barrier Reef, with climate change set to wreck irreversible damage by 2030 unless immediate action is taken, marine scientists said Thursday.
In the long term, critics say, this dynamic could speed up the already fast-consolidating U.S. food industry, with broad ramifications for both human and environmental health.
“When non-operators own farms, they tend to source out the oversight to management companies, leading in part to horrific conditions around labour and how we treat the land,” Anuradha Mittal, the executive director of the Oakland Institute, a U.S. watchdog group focusing on global large-scale land acquisitions, told IPS.
“They also reprioritise what commodities are grown on that land, based on what can yield the highest return. This is no longer necessarily about food at all, but rather is a way to reap financial profits. Unfortunately, that’s far removed from the central role that land ultimately plays in terms of climate change, growing hunger and the stability of the global economy.”
Scientists say 20th century was one of wettest in 1,300 years and that history shows California could be in for a very long dry period
While a three-to-five-year drought is often thought of as being a long drought, Ingram says history shows they can be much longer.
"If we go back several thousand years, we’ve seen that droughts can last over a decade, and in some cases, they can last over a century," she says.
Podesta’s timely focus on conservation cheers liberals, worries Republicans and vulnerable Democrats.
World policymakers need to acknowledge that the world is already on track for global warming beyond 2°C, and prepare for drastic impacts, scientists say in a new commentary.
Andrew Jordan of the Tyndall Centre for Climate Change Research in Norwich, England, co-author of a similar call for a reassessment of the 2°C target, said the IPCC actually “suggested” in its September report that the 2°C target would be breached. The IPCC report showed that the world’s “carbon budget,” the amount of greenhouse gas that can be emitted without exceeding 2°C, could be used up entirely by 2040, Jordan noted.
