Mudslides and climate change. Does the recent tragedy in Washington state portend to much such devastating mudslides in a changing climate?

The Relationship Between Landslides and Climate Change in North America

While the causal factors involved in landslides are complex, there is a strong body of research which supports the idea that climate change will increase the number of slides. The key factor connecting climate change to landslides is water. This linkage has been evinced in both geological and hydrological research. As University of Washington geologist Dave Montgomery explained in an…

Latest IPCC Installment Highlights Climate Risks, Potential for Adaptation

The threats, risks and costs associated with a rapidly changing climate continue to mount, making the benefits and rewards to be gained by enacting global adaptation and mitigation policies and initiatives yet more valuable and urgent, according to the latest installment of the UN IPCC’s Fifth Assessment Report.

CSIRO measuring atmospheric carbon

Video Friday: Monitoring Atmospheric Carbon

Dr. Paul Fraser of the Australian Commonwealth Scientific and Industrial Research Organisation (CSIRO) explains how he and his team monitor atmospheric CO2 concentrations globally. Beginning in 1974, CSIRO was one of the first non-American organization to measure CO2 in the atmosphere. Dr. Fraser explains how scientists isolate isotopes in carbon to determine its source, whether from the natural biosphere or…

Artic Sea Ice and Albedo: Ice Free Season Growing 5 Days per Decade

Arctic ice autumn freeze-up starting later  - According to new research to be published in the forthcoming issue of Geophysical Research Letters, the ice-free season in the Arctic is growing by five days per decade. Analysis of satellite data by a team of researchers headed by Julienne Stroeve indicate increasing absorption of solar energy in the summer Arctic ocean is pushing…

Using satellite data researchers find effect of melting Arctic sea ice has greater impact on global warming than expected

Melting Arctic Sea Ice Causing More Warming Than Expected

Scientists have long modeled the expected warming due to the decreased albedo effect as melting Arctic sea ice exposes more open ocean. As early as the 1960′s climate researchers have predicted how this phenomenon will amplify global warming. Arctic ice melt, albedo and global warming Albedo is measured as a percentage, in this case the percentage of solar radiation a…

Will the Keystone XL pipeline be approved? If so, it's for all the wrong reasons

Refuting the 9 Reasons Why the Keystone XL will be Approved

Despite all of the efforts being made to resist the construction of the Keystone XL, it will likely gain the approval of U.S. President Barack Obama. Supporting evidence for the notion that we will move ahead with the Keystone XL comes from the corporate sector. Powerful corporate interests have considerable resources that often enable them to ascertain the outcome of…

British Isles Endure Unprecedented Flooding

UK Flooding adds to global extreme weather events Even while the US East shivers in record cold, Alaska basks in heat and California experiences extreme drought (despite the recent rain), it is the British Isles that are truly being hammered by extreme weather. As much as some folks snipe at the oft-repeated phrase of late, the polar vortex and stalled…
