The History Of The "Red Planet" May Help Us To Understand Climate Change on Earth

The question of whether life ever existed on Mars has inspired scientists - and songwriters - for decades. The Red Planet is currently an arid, icy desert where no sign of life remains, but was it always this way?

It is widely recognised that living entities have three basic requirements: standing water, an energy source and the five...

Rapid Onset Of Climate Change Could Seriously Affect Feeding Patterns In Marine Life

Climate change is already upon us, experts say, and we are already feeling its adverse effects in the form of extreme weather events: scorching temperatures leading to droughts, torrential rains causing widespread flooding, and record freezes bringing feet of snow.

But what of the less obvious effects of global warming?

First Sign of Methane Outgassing from Arctic Ocean

Scientists from the University of Stockholm have detected gigantic methane plumes escaping from the sea floor of the Laptev continental slope. It is believed that this is due to the melting of methane hydrates that have been frozen on the floor of the ocean. They are now melting and releasing the gas because the Arctic Ocean, along with the rest...

Weekender: Scientists Predict Mass Extinction In 30 Years - How Can We Change This Outcome?

Mass extinctions have happened periodically throughout Earth's history for a variety of different reasons, with the usual culprits being either asteroid hits or climate change. The Eocene extinction was originally thought to have been caused by climate induced issues, but recent evidence has suggested that the changes in the weather occurred due...

Wondering What the Effects of Climate Change Will Be? They're Already Here, Say Scientists

An important new report released this week has revealed that the United States is being severely affected by human-induced climate change across the whole of the nation.

The report, entitled the National Climate Assessment, was compiled by a large panel of...

Rate of Extinction Reaches Historic Proportions

Many vertebrate species (that category includes us) would have to evolve about 10,000 times faster than they have in the past to adapt to the rapid climate change expected in the next 100 years.

Scientists analyzed how quickly species adapted to different climates in the past, using data from 540 living species from all major groups...

2001 Temperatures 2nd Highest on Record

The Earth?s temperature in the year 2001 was the second highest since global records began 140 years ago, according to the UN?s World Meteorological Organization.The higher temperatures led to an increase in the severity and frequency of storms and to droughts and other unusual weather conditions.

Nine of the 10 warmest years in the...

Methane May Be Major Cause of Climate Change

NASA scientists have discovered that a huge release of methane from gas that had been frozen beneath the ocean floor heated the Earth by up to 13 degrees Fahrenheit 55 million years ago. They used a computer simulation to better understand the role of methane in sudden climate change in the far past. While today?s greenhouse gas studies focus...

Alaska?s Glaciers Thinning

Alaska contains several thousand valley glaciers, and fewer than 20 of them are advancing, while many of the rest are retreating, according to a study by U.S. Geological Survey (USGS) scientist Bruce F. Molnia. Significant glacier retreat, thinning, stagnation, or a combination of these changes characterizes all eleven mountain ranges and three...

Far North Record Heatwave

The far north town of Iqaluit in Canada is experiencing extraordinary heat. Temperature spikes in the far north are a sudden climate change danger signal, and the situation in this area is highly unusual.

"We've had a really stagnant situation," saod Yvonne Wallace, a meteorologist with Environment Canada's Arctic Weather Centre in...

Global Warming to Become Deadly in Asia

Parts of Asia face deadly climate changes and natural disasters caused by pollution and atmospheric warming, sooner than the rest of the world. Floods in Southeast Asia, glaciers melting in the Himalayas, islands disappearing in rising seas and huge dust storms in China are just some of the climate disasters caused by industrial pollution, car...

Freak Heatwaves Strike Spain, Russia

Spain?s North African enclave of Melilla, on a small peninsula on Morocco's Mediterranean coast, was hit by freak heatwaves on Monday, sending temperatures shooting up as much by as 30 degrees Fahrenheit in a matter of minutes.

Spain?s Meteorological Institute said it registered two heat surges during the morning, the first sending...

Now it's Snowing--in Saudi Arabia!

Thousands of people seeking relief from 100-plus temperatures in Saudi Arabia were panicked by an unprecendented snowfall of several inches. Thousands were trapped in a mountainous area in the southern part of the country.

Civil defense teams were called in after 75 people were injured in the panic that followed. Several hundred people...

Britain Could Become Much Colder

Scientists are now reporting that Britain?s winter climate could become as cold as Moscow?s, according to new evidence that the vital ocean currents of the North Atlantic are beginning to change.

Measurements over the past 50 years have shown that a key deep-sea current running along the ocean floor that separates Scotland from the...

Methane Buildup Predicted in Superstorm Book Confirmed

Scientists have discovered that the same massive release of methane into the atmosphere that caused sudden climate change 14,000 years ago has already started to happen again.

At that time, there was a sudden, devastating change in earth?s climate. It took place when dramatic drops in temperature followed an equally dramatic temperature...
