• Indian Ocean phenomenon helps in predicting extreme weather

    The Indian Ocean Dipole is the difference in sea-surface temperatures between the western and eastern part of the Indian Ocean. A better understanding of the relationship between the Indian Ocean Dipole and extreme weather events will enable farmers, industry, communities, and governments better to anticipate and prepare for droughts and increased bushfire risk, up to six months in advance of the event.

  • Smart software fighting fire with #fire

    Australia’s key disaster management agencies have joined forces to tackle the problem of how to access and interpret information gathered during bushfires and other natural disasters to help emergency services save lives and property.

  • Helping farmers cope with climate change is big business

    Monsanto estimates there is a $20 billion market for employing massive data analysis to provide weather forecasting and crop-growing advice tailored to individual plots of land. With a $300 billion agriculture industry in the United States exposed to climate change, predicting the effects of warming temperature is critical to the industry. Monsanto has recently acquired – for $1 billion — the Climate Corporation, a Silicon Valley company which uses data analysis and algorithms to redefine how farmers grow and harvest crops. The company provides farmers with insights which predict weather pattern and the changing effects on crops.

  • Modeling earthquakes and explosives reactions

    Researchers are developing mathematical models that can help in reducing rock fracturing and soil liquefaction caused by natural or man-made disasters. The outcomes of the research could improve safety levels in the mining and petroleum industries, and play a critical role in the ability of civil infrastructure to withstand disasters such as earthquakes and explosions.

  • Methane emissions in the U.S. exceed government estimates

    Along with carbon dioxide, methane is one of the most important greenhouse gases in terms of its potential to raise global temperatures. It also encourages the formation of surface ozone in cities and affects other aspects of atmospheric chemistry. A new study finds that emissions of methane from fossil fuel extraction and refining activities in the South Central United States are nearly five times higher than previous estimates. The collaborative study indicates that in addition to fossil fuel extraction, animal husbandry is also a major contributor to the higher-than-expected methane emissions.

  • NIST: Joplin tornado highlights need for building design, construction standards

    Nationally accepted standards for building design and construction, public shelters, and emergency communications can significantly reduce deaths and the steep economic costs of property damage caused by tornadoes. That is the key conclusion of a two-year technical NIST investigation into the impacts of the 22 May 2011 tornado that struck Joplin, Missouri. Report and recommendations released for public comment.

  • List of most-at-risk L.A. buildings to be released

    Scientists have compiled a list of concrete buildings in Los Angeles which could be at risk of collapsing in a major earthquake. The list identifies about 1,500 concrete structures built before 1980 which need further study to determine their risk level. Structural engineers insist that hundreds could die if any of the buildings collapsed.

  • Sea-level rise could exceed one meter in this century: experts

    Sea-level rise in this century is likely to be 70-120 centimeters by 2100 if greenhouse-gas emissions are not mitigated, a broad assessment of the most active scientists who research in the area, and who are the most prolific publishers on that topic, has revealed. In contrast, for a scenario with strong emissions reductions, experts expect a sea-level rise of 40-60 centimeters by 2100. Ninety international experts, all of whom published at least six peer-reviewed papers on the topic of sea-level during the past five years, provided their probabilistic assessment.

  • Understanding Greenland Ice Sheet melting helps sea-level forecasts

    New insight into how glacier movement is affected by melting ice in summer could help predictions of sea level rise. In 2012, an exceptionally warm summer caused the Greenland Ice Sheet to undergo unprecedented rates of melting. Researchers have found, however, that fast summer ice flow caused by significant melting is cancelled out by slower motion the following winter.

  • Winners announced in NY, NJ coastal protection ideas competition

    Ten of the ideas submitted to the Rebuild by Designcompetition, launched by the Hurricane Sandy Rebuilding Task Force, were selected as the most promising concepts for sustainable ways to protect Sandy-affected regions from future catastrophes.

  • Smaller asteroids could cause bigger problems

    On 15 February an asteroid burst over the Russian city of Chelyabinsk. Scientists estimate that the Chelyabinsk event was equivalent to an explosion of about 500 kilotons of TNT. At its peak, the airburst appeared to be thirty times brighter than the sun. The asteroid fireball that injured about 1,500 people and damaged more than 7,000 buildings, collapsing roofs, and breaking thousands of windows. Scientists say that because the frequency of a strike of an asteroid of this size has exceeded expectations, with three such strikes in just over a century – Chelyabinsk in 2013, Tunguska in 2008, and a large airburst in the South Atlantic in 1963 — the number of similar-sized asteroids capable of causing damage may be greater than suspected.

  • Study finds more spending on fire suppression may lead to bigger fires

    Researchers found that fire management can fall into the firefighting trap: Energy and resources are spent mostly on fire suppression — putting out fires in the moment — while less attention is devoted to fire prevention, such as clearing brush and building fire lanes during the off-season. After severe fires, policymakers funnel even more funds into fire suppression for the next season, but this attention to fire suppression may undermine prevention efforts. The result, counterintuitively, is even worse fires the following season, due to the buildup of fire-prone materials such as dried tinder and dead trees. The researchers emphasize balancing fire suppression with prevention measures.

  • Evacuation modeling: finding the best time (and way) to get going

    Reports from the Philippines reveal a lack of typhoon preparation and evacuation efforts. When to evacuate — and how – could spell the difference between life and death. Typhoons can cause widespread flooding of surrounding areas, and do not just affect what lies in the path of the storm. Planning an evacuation is a game against nature. Few plans are safe, and the number and complexity of decisions quickly becomes overwhelming — especially as rising water or traffic accidents block roads — but computers can dramatically help emergency services design evacuation plans which people can actually follow.

  • Detecting radioactive material in nuclear waste water

    As the Fukushima crisis continues to remind the world of the potential dangers of nuclear disposal and unforeseen accidents, scientists are reporting progress toward a new way to detect the radioactive materials uranium and plutonium in waste water.
