Climate Change in Northern Latitudes
Climate Change in Northern Latitudes
In the Northern regions, the melting of Arctic ice is just the tip of the iceberg. The consequences of global warming could have worse effects than suspected. This frozen region “hides” 1,700 billion tons of organic carbon, the melting of which could accelerate warming. This seminar also spells out the various contributors to relative sea-level changes in the Northeast Pacific, examines likely adaptations, and demonstrates how climate change influences forests and the way they are managed.
Northern Soils: What if They Thaw?
Public perception is focused on the melting of arctic ice as one of the indicators for climate change. However, 1,700 billion tons of organic carbon are kept in the soils of regions above the latitude of 50° N, representing 16 percent of global land surface. Organic carbon in soils is the biggest terrestrial carbon pool and presents an important factor in future climate change projections. Permanently frozen grounds, together with extensive peat lands, ensure that those soils are a significant carbon sink. Thawing could lead to substantial release of greenhouse gases into the atmosphere and an increase in global warming. Other consequences include the disruption of infrastructure and urban areas from the thawing of the underlying permafrost. Researchers aim to address these topics through extensive monitoring of the status of these soils as well as through modeling of possible scenarios affecting this part of the globe.

Causes and Effects of Relative Sea-Level Changes in the Northeast Pacific
How will the Northeast Pacific be affected by relative sea-level changes during the 21st century and beyond? In part the effects will depend on causes, both global and regional. The familiar global list includes interactions among the solid Earth, atmosphere, oceans, and cryosphere in response to orbital and anthropogenic climate forcing. Regional variations on these themes include earthquake-induced subsidence as large as 1.5 meters, as happened during the great subduction-zone earthquakes that struck Cascadia in 1700 and Alaska in 1964, and localized effects of glacial isostasy, sediment loading, and groundwater overdraft. But the effects will also depend on ecological and human adaptations. This session first reviews the various contributors to relative sea-level changes in the Northeast Pacific, and then examines likely adaptations with an emphasis on shores in British Columbia.

Forest Fires in Canada: Impacts of Climate Change and Fire Smoke
Canada is a country that is defined by its forests. It is a nation for which the social, economic, and ecological importance of its forests cannot be overstated. This session brings together a team of researchers who have a demonstrated track record of interdisciplinary collaboration to discuss climate change impacts on the risk of forest fires, challenging problems in fire management and health effects, and the analysis of local fire history using paleontological and statistical methods.

Detecting Temporal Changes in the Seasonality of Forest Fire Risk in Canada
Space missions are typically multi-national because of their expense, and the expertise required pursuing them often spans nations. These collaborations cause a flattening of the science of astronomy through the creation of the observatory, by opening the time allocation of the observatory to the whole world of astronomers through competitive proposals and the resulting public data bases of observations.
The Life Cycle of Matter in Galaxies: Results from the Herschel Space Observatory
The panel will describe some of the exciting results from the Herschel Space Observatory, a European Space Agency led mission with significant collaboration from NASA and the Canadian Space Agency, that touch on all aspects of the life cycle of matter in galaxies. It has the largest single mirror ever built for a space telescope, and will collect long-wavelength radiation from some of the coldest and most distant objects in the universe. In addition, Herschel is the only space observatory to cover a spectral range from the far infrared to sub-millimeter. The mission is designed to study the formation of galaxies in the early universe and their subsequent evolution; investigate the creation of stars and their interaction with the interstellar medium; observe the chemical composition of the atmospheres and surfaces of comets, planets and satellites; and examine the molecular chemistry of the Universe

The Fermi Gamma Ray Mission: Transforming Our View of the High-Energy Universe
Since launch in 2008, NASA's Fermi Gamma-Ray Space Mission has made major findings on the nature of the high-energy sky. Fermi's Large Area Telescope surveys the entire sky every 3 hours and has discovered more than a thousand new sources of gamma-rays. These include detections of hundreds of active galaxies, providing fresh insight into how supermassive black holes can accelerate jets of particles moving close to the speed of light. Fermi has found scores of new gamma-ray emitting pulsars, a huge leap on the six known prior to launch. The gamma-ray sky is constantly changing. The panel will discuss the implications of these observations and report on the latest exciting new results.

The historical pattern of medicine has been responsive; symptoms appear and then they are treated. Recent scientific and technical advances, however, open the prospect of predictive medicine, in which the appearance of disease in an individual or region is foretold and prepared for or even prevented. Advances in biological sciences support lifelong, detailed monitoring of body chemistry, with an eye to early detection of changes. In vitro cell biology and physiological measurements provide unprecedented insight into the condition of individual humans and the levels of environmental stressors. Web queries have famously been used for early detection of the arrival of flu in a city. Finally, on the largest scale, satellite imaging can support predictions of the impending outbreak of vector-borne diseases in entire regions.

Can Proteomics Fill the Gap Between the Genome and Phenotypes?
This session focuses on the unexpected, the mislocalized, and the misunderstood proteins in proteomics. By considering how proteolytic processing, splicing, non-conventional trafficking, and protein-protein interactions lead to new and unexpected roles for protein systems then the proteomics of tomorrow in the Human Proteome Project today can fill the gap between genomics and phenotypes. Panelists highlight how information is generated in a system that as yet cannot be predicted from the genetic code, protein sequence, or expression data.

Seeing Biosphere's Dark Matter: Genomic Methods on Unculturable Microbial Diversity
A decline in biodiversity poses dramatic consequences to almost every aspect of human development, either directly or indirectly, from food supply to global health, from climate change to the economy. Our ability to respond to these threats depends on efficient and thorough exploration, classification, and interpretation of biodiversity. Some components of the biosphere are visible to the eye, such as plants and animals, and have obvious importance. But microorganisms, the invisible majority of living forms on planet Earth, play critical roles in regulating global-scale processes and driving essential nutrient cycles that support all life forms. This session will illustrate the challenges of exploring microbial diversity in natural habitats such as the open oceans, deep into the ground, or inside our own bodies.

Delivering on the Promise of the Human Genome Project
During the 11 years since its completion, the human genome project induced many advances in science and medicine, ranging from deeper understanding of disease development and progression, to expanding bioinformatic and diagnostic tools, to development of novel therapeutics for cancer, metabolic disorders, and other ailments. A direct application of the vastly expanded genetic information is the development of siRNAs and microRNAs as targeted therapeutics for cancers, skin disorders, and other disorders. These readily synthesized and specific modulators of messenger RNA expression have huge potential for selective and specific treatment. However, the complications of delivering these biologicals to the cytoplasm of target cells stand in the way of harvesting the therapeutic fruits of the human genome project. This session will examine the problems encountered by academia and the pharmaceutical industry and discuss cutting-edge and current efforts to circumvent these barriers.
