World at Risk - Year 12 Edexcel Geography

It produces less radioactive waste and more power but it remains unproven on a commercial scale

New figures show we are still hurtling towards dangerous climate change - at a time when policymakers are running out of ideas

Population growth and water supply are on a collision course. Hunger is set to become the main issue

As the world's oceans warm, their massive stores of dissolved carbon dioxide may be quick to bubble back out into the atmosphere and amplify the greenhouse effect, according to a new study.

There were supposed to be 50 million climate refugees by the end of last year, so where are they? New Scientist investigates

A RACE is on to retrieve the first million-year-old sample from deep within Antarctica's ice. It's a prize that could help us understand what drives major changes in Earth's climate.

It's been a severe start to the spring season in the United States. Tornadoes have ravaged the southeastern US, flooding threatens much of the Midwest, and wildfires are scorching Texas. But according to researchers, a confluence of seasonal oscillations in weather patterns, rather than climate change, is to blame. And growing populations mean that grim casualty figures from such events may become the norm.

Shifts in the climate over the past three decades have been linked to a 5.5% decline in global wheat production, a study has suggested.

Around the world, people use quicklime to balance the pH of their fish tanks. Could governments do something similar to correct the pH of our acidifying oceans?

The scale of just how dry the start of 2011 has been is evident in some fascinating data from one of Europe's latest Earth observation satellites.

In Italy, Asia and New Zealand, long-range earthquake predictions from self-taught forecasters have recently had people on edge. But is it possible to pinpoint when a quake will strike?

Sicily's Mount Etna spewed lava and sent clouds of ash into the air when it erupted in the early hours of Thursday.

Glacial lakes in the Himalayas could pose a major hazard to population centres if they are ruptured by earthquakes, scientists say.

The latest report on Renewables from the Committee on Climate Change (CCC) offers lukewarm support for electricity generation from tidal streams. The UK has some of the fiercest tidal currents in the world, but the CCC says the tidal turbines will deliver energy at a higher cost than PV in 2040. The assumptions behind this pessimism are questioned in this article.

Mega Droughts and Deluges, Extreme Rain Events, Super Storms, Giant Snowfalls … Here to Stay: Climatologist

Microbes with tweaked DNA can convert sunlight and carbon dioxide into oil, but will it ever power our cars?

The Australian Climate Commission has warned that the world's sea levels could rise by 1m by the end of the century, much more than thought.

The World Health Assembly is due to address water and sanitation for the first time in its history at its meeting this week. Water Aid is calling on leaders to provide safe water and sanitation to transform the lives of people in countries like Uganda, where the lack of access to these basic services is a major cause of disease

To its eternal shame, the Republican party has taken climate change denial out of the crank fringe and made it mainstream

As the world's climate warms, will the Pacific Ocean make matters worse by dumping extra heat into the atmosphere? Ancient fossils and the latest modelling both suggest such fears may be unfounded. But there is a downside: extreme weather caused by the Pacific's shifting waters might become more common.
