Most Extreme Precipitation Events To Become More Intense In Warming World

A new study led by the US National Oceanic and Atmospheric Administration has found that as the planet warms further as a result of increasing levels of greenhouse gasses in the atmosphere, the more moisture in the warmer atmosphere will make the already extreme precipitation events more intense. The study further showed that a 20% […]

Thawing Permafrost Bad News for Global Warming

Permafrost covers almost a quarter of the northern hemisphere, and according to recent calculations contains 1,700 gigatonnes of carbon – that’s an amount twice what is currently in our atmosphere. A new report released by the UN Environment Programme (UNEP) entitled ‘Policy Implications of Warming Permafrost’ warns that the release of this permafrost carbon could seriously amplify

Warming Earth Results in Contrasting Consequences, But Not So Fast

New research by scientists has found that biodiversity on Earth actually increases as the planet warms. However, importantly, this growth is observed in the evolution of new species over millions of years and is most often accompanied by the extinction of other species.

The present trend of accelerated warming is not likely to boost global biodiversity, rather, it is set to destroy it.

New Report Card Shows Climate Change Affecting Australia's Oceans

Launched today by the CSIRO is the 2012 Marine Climate Change in Australia Report Card which demonstrates that climate change is having significant impacts on the marine ecosystems that border Australia. Aspects of the study include changes in sea temperature, sea level, the East Australian Current, the Leeuwin Current, and El Niño-Southern Oscillation, as well as marine

Megapolitan Expansion Wreaks Havoc on Summertime Warming

The United Nations’ 2011 Revision of World Urbanization Prospects report outlined the expected growth of urban population to gain more than 2.5 billion inhabitants by 2050, which will necessarily require a massive expansion of urban landscapes, most likely at the detriment of natural landscapes. In a first of its kind study which attempts to quantify

Warming Will Continue Even with Immediate Eradication of Greenhouse Gases

Even if we somehow managed to restore our planet’s atmosphere to zero greenhouse gases, temperatures would still continue to rise by a few tenths of a degree over the next 10 years. That is the best case scenario discovered by researchers who have written a paper to be published online in the journal Nature. Written

Ocean Hotspots and Strengthening Winds Driving Ocean Currents Poleward

Oceanographers from across the world have identified a series of ocean hotspots that have been generated by strengthening wind systems across the planet that are successfully pushing oceanic current polewards, well beyond their known boundaries. The hotspots – locations where the temperature has increased outside of expected norms – have formed alongside ocean currents that

Amphibian 'Blitz' Project Uses Crowd Sourcing to Track Endangered Species

The Global Amphibian Blitz project is an on-line information sharing hub for non-professional naturalists and biologists whose goal is to track and record sightings of amphibians the world over. This information will then help professional researchers to document and determine where protection efforts are most needed. Global amphibian distribution is quite lacking in documentation and data. The term ‘blitz’ is used here in the belief that this crowd-sourcing method of species inventorying will speed up research and conservation efforts for one of the world’s most vulnerable classes of animal life.

Shifting Biomes in Alaska

Scientists have hypothesized that evergreen forests will increase their growth at the margin of present tundra areas, while simultaneously declining at the margins of temperate forests to the south. New research highlights this shift in biomes caused by a warming climate by combining data gathered from satellite imagery and tree rings. The study, which will

Is Our Hot Past Representative of Our Future

An analysis by National Center for Atmospheric Research (NCAR) scientist Jeffrey Kiehl published in the most recent edition of the journal Science in the ‘Perspectives’ section has concluded that the sheer scale of climate change during Earth’s ancient history points to temperatures rising far more than expected in Earth’s immediate future. Kiehl brought together several

NASA: November 2010 Hottest November on Record, 2010 Likely Hottest Year on Record

Yes, yes, it’s winter and it’s getting colder, especially here in Europe where I’m living. But November actually turned out to be the hottest November on record globally, according to the latest data from NASA, and 2010 is looking like it will be the hottest year on record after all, despite the fact that we are

Southwestern Forests Weakened by Drought and Rising Temperatures

New research into the tree populations of Southwest America have found that these forests will face reduced growth if temperatures continue to rise and rain continues to fall. The researchers looked at tree-ring data and climate models to find that the rising temperatures and falling precipitation have led to a decline in the fitness of

Gradual Warming Not Entirely Responsible for Greenland Icesheet Flow

A new study to come out of the University of British Columbia has shown that sudden changes in the amount of meltwater contributes more to the acceleration, and thus the eventual loss, of the Greenland ice sheet than the gradual increase of temperature, reversing previously thought views on the matter. “The conventional view has been

'Devastating Climate Shock' Needed to Spur Climate Change Policy

In his alarm-ringing NY Times op-ed on Climate Change, professor Homer-Dixon* draws a comparison with the 2008 financial “meltdown” which finally led to new financial regulations, even though warnings of a housing bubble (and an emerging recession) were being made prior to the crisis. He advocates societies designing a contingency plan (‘Plan Z’ ) to deal with the immediate after-effects of one or more climate change disasters.

Dry Times for Western North America, Climate Trends Forecast

Researchers Overpeck and Udall cite a litany of troubling trends to support their prediction: “soaring temperatures, declining late-season snow pack, northward-shifted winter storm tracks, increasing precipitation intensity (note: not total rainfall), the worst drought since measurements began, steep declines in Colorado River reservoir storage, widespread vegetation mortality, and sharp increases in the frequency of large wildfires.”

New Analysis Predicts Planet Warming Will Lead to Massive Loss of Biodiversity

Under a scenario that is nothing short of fairy tale-optimistic and unrealistic, a pair of authors from Scripps Institution of Oceanography at UC San Diego has predicted a minimum warming of 2.4° C (4.3° F) above pre-industrial levels. And even an increase that is seemingly that small, falls within the IPCC’s (Intergovernmental Panel on Climate
