Time in Modern History, Images Show

For the first time in modern history, the eastern basin of the South Aral Sea has gone completely dry, as this

Enlarge

Drying of Aral Sea
NASA satellite image captured in late August shows. The Aral Sea is an inland body of water lying between Kazakhstan and Uzbekistan in central Asia. It was once one of the four largest lakes in the world, but it has been shrinking markedly and dividing into smaller lobes since the 1960s, after the government of the former Soviet Union diverted the region's two major rivers to irrigate farmland. One Aral Sea researcher suggested that it has likely been at least 600 years since the eastern basin entirely disappeared. Decreasing precipitation and snowpack in its watershed led to the drying this year, and huge withdrawals for irrigation exacerbated the problem. Water levels are expected to continue to show major year-to-year variations depending on precipitation and snowpack levels, the researcher said.

If the goal is met, it will cut carbon emissions by an amount equal to taking 1 billion vehicles — every car on the planet — off the road, the UN said. Notably missing from the list of committed countries was Brazil, which has been a key player in Amazon deforestation, because of concerns that the pledge would clash with national laws permitting managed deforestation. Critics say ending deforestation is nearly impossible without Brazil's cooperation. In addition to the 32 national governments that signed onto the declaration, 35 corporations, including Kellogg's, L'Oreal, and Nestle, pledged to support sustainable forest practices in their supply chains.

Russia experienced a heat wave that led to food hoarding and price-fixing of staple crops by speculators, according to the report, which was commissioned by Oxfam. A drought in East Africa in 2010 through 2011 was tied to an uptick in armed conflicts in the region, which interrupted international and domestic aid for six months. Crop prices reached record levels in several markets, including wheat in Ethiopia, maize in Kenya, and red sorghum grain in Somalia, the report notes. Investing in additional health facilities, establishing pre-positioned food supplies, and other tactics aimed at mitigating the effects of future heat waves, droughts, and floods, could help to blunt the effects of climate change on the poorest and most vulnerable populations, the researchers say.

global mean surface temperature to rise more than 2 degrees C beyond the pre-industrial average, according to researchers with the Global Carbon Project. Combined historical and future carbon dioxide emissions must remain below 3.2 trillion metric tons to have a 66-percent chance of keeping that temperature increase below 2 degrees C — the internationally accepted benchmark for restraining global warming. But two-thirds of this allotment has already been emitted, and at the current pace of emissions, the global population will burn through the rest within the next 30 years, the researchers conclude. CO2 emissions rose 2.3 percent in 2013 and are on track to increase by 2.5 percent in 2014, according to the report, which was released ahead of this week's UN climate summit.

people in the world, now 7.2 billion, will increase to between 9.6 and 12.3 billion in 2100. Published in the journal Science, the study counters the widely accepted projection that global population will peak at roughly 9 billion by 2050, then gradually decline. The new study instead finds a 70-percent likelihood that population will grow continuously throughout the century to reach 10.9 billion by 2100. Researchers attribute the higher projections, in part, to increasing fertility rates in sub-Saharan Africa, where population growth had been predicted to continue slowing. The Guardian notes that many widely cited global policy assessments, such as recommendations from the Intergovernmental Panel on Climate Change, assume a population peak by 2050.

been growing significantly faster and stands have become larger since the 1960s. The study, published in Nature Communications, was based on 600,000 individual tree surveys conducted since 1870 at a central European forest study site. European beech and Norway spruce, the dominant tree species in the experimental plots, grew 77 and 32 percent faster, respectively, than they did 50 years ago, the analysis found. The trends are primarily due to rising temperatures and longer growing seasons, the researchers say, although increasing carbon dioxide and nitrogen levels in the atmosphere could also play a role. The stages of tree development haven't changed, the researchers say; instead, trees are moving through their development trajectory much faster than before. The changes could affect other plants and animals in the forest ecosystem that rely on specific phases of forest development, the study notes.

cities could save $100 trillion and cut transportation-related carbon emissions by 40 percent by 2050, according to an analysis by researchers at the University of California, Davis, and the Institute for Transportation and Development Policy. Urban transportation-related emissions could double by 2050 as growth continues in major cities in China, India, and other developing countries. But if China alone were to develop extensive bus rapid transit and commuter transit networks, its predicted transportation-related emissions in 2050 could be cut by 40 percent, the analysis found. The U.S. — currently the world's largest contributor to urban transportation-related emissions — is seeing declines in that sector as population growth slows, vehicle fuel efficiency improves, and people drive less. But those emissions cuts could accelerate sharply if urban mass transit were improved, the report said.

16 Sep 2014: Tackling Climate Change Could
Pay Off in as Little as 15 Years, Report Finds

Limiting greenhouse gas emissions globally over the next 15 years is both economically feasible and likely to save money, according to a new report from the Global Commission on the Economy and Climate. Between 2015 and 2030, nations are expected to invest roughly $90 trillion in urban land-use and energy infrastructure, the analysis estimated. Steering those investments toward renewable energy, efficiency improvements, and other low-emission technologies would make that global investment more costly, the panel of government and business leaders conceded. But these costs could eventually be offset by the lowered operating costs associated with renewable power, the report suggested. Although they are difficult to quantify, health care savings associated with improved air quality would also offset costs. According to the report, the biggest challenges for governments will be enacting stronger rules and policies that favor low-carbon development, such as cutting the $600 billion currently spent on fossil fuel subsidies.

feature organic ingredients grown or raised on nearby farms, including the one that surrounds his Hudson Valley restaurant. So it’s striking that in his new book, The Third Plate, Barber maintains that the movement he has been championing hasn’t gone far enough. In an interview with Yale Environment 360, Barber says if the farm-to-table movement is to truly support sustainability, end the rise of monocultures, and produce delicious food, it’s the table that must support the farm, not the other way around. And that, he says, calls for a new way of cooking and eating.

The maps are derived from worldwide databases of population, power plants, and national fuel use statistics, and they encompass 15 years of data. Among other findings, the analysis revealed increased emissions in China, India, Europe, and the northern U.S. in 2010, after the peak of the global financial crisis. The researchers say this reflects faster recoveries from the crisis in those regions compared to, for example, the southeastern U.S., where emissions lagged in 2010. The results of the analysis match ground-level measurements, confirming the accuracy of the maps, the researchers say.

The largest losses were in the states of Para and Mato Grosso, in central Brazil, which are experiencing widespread agricultural development. The building of new roads and dams, along with illegal logging, also contributed to the rise in deforestation. Brazilian police frequently target illegal logging operations, but environmental groups say more enforcement is needed. Deforestation in Brazil peaked in 2004, when over 11,580 square miles of forest were destroyed. Worldwide, deforestation is responsible for roughly 15 percent of greenhouse gas emissions — more than all types of transportation systems combined.

be less interested in hunting prey, according to research published in Global Change Biology. In laboratory experiments emulating CO2 concentrations as they are expected to be by the middle and end of this century, scientists from the U.S. and Australia found that the smooth dogfish shark became uninterested in squid odors — sometimes avoiding them altogether. Sharks in control waters pursued prey scents four times more often than sharks in waters with high CO2 levels, the study found. Rising ocean acidity can disrupt the proper firing of neurons, the scientists say, because it interferes with a specific receptor present in most marine organisms with a nervous system. A study earlier this year found that fish in waters with increased acidity were also less able to detect predator odors.

08 Sep 2014: U.S. Dietary Guidelines Would
Lead to Rise in Emissions, Study Says

Following U.S. federal guidelines for a healthy diet is likely to increase greenhouse gas emissions, even though the guidelines recommend a diet with less meat than the average American currently consumes, according to a recent analysis in the Journal of Industrial Ecology. Compared to U.S. Department of Agriculture dietary guidelines, American's don't eat enough fruits, vegetables, seafood, and dairy, and they consume too much meat, eggs, nuts, soy, oils, solid fats, and added sugars. If the population were to shift its diet to match USDA guidelines, greenhouse gas emissions would actually rise by 12 percent, researchers found, because calories from meat, eggs, fats, and sugars would largely be replaced by dairy products. Methane emissions from dairy and beef cattle contribute significantly to atmospheric greenhouse gas levels. The findings highlight a need to consider both environmental and health objectives when making dietary recommendations, the researchers say.

In an interview with Yale Environment 360, Palen talks about why a moratorium on new tar sands developments is needed, how the decision-making process is biased in favor of short-term economic benefits, why the fate of the proposed Keystone XL Pipeline is critical, and what can be done to begin factoring in the real costs of exploiting the tar sands.

03 Sep 2014: Mobile Phone Networks Can
Help Monitor Global Rainfall, Study Says

New research shows that mobile phone networks, which cover 90 percent of the world's population, can help track rainfall events — a task that has proven difficult for both advanced satellite systems and ground-level observation networks. By compiling data on signal disruptions from mobile phone networks in Burkina Faso in West Africa, a team of researchers was able to calculate with 95 percent accuracy both the location and volume of rain that fell, even during short-lived storms, according to a report in Geophysical Research Letters. Mobile phone companies maintain detailed records on signal disruptions, which can occur when water droplets block and deflect signals between antennae, to determine whether their networks are functioning properly. By tapping into those records, researchers could distill data on rainfall events at extremely fine spatial and temporal scales. As mobile phone networks expand across the globe, such data could be used to create highly accurate rainfall maps, researchers say, although gaining access to records could prove difficult.

ranging from building more reservoirs to controlling population growth, according to research from Canada and the Netherlands. Water stress is defined as occurring when more than 40 percent of the water from a region's rivers is unavailable because it is already being used — a situation that currently affects roughly one-third of the global population. Writing in Nature Geoscience, the scientists propose six steps they believe can help reduce water stress: planting crops that use water and nutrients more efficiently; using more efficient irrigation methods; improving the efficiency of water use in homes, industry, and municipalities; limiting the rate of population growth so global population stays below 8.5 billion by 2050; increasing reservoir water storage capacity; and intensifying water desalination operations by 50-fold.

The agreement would combine legally binding updates to an existing 1992 climate change treaty — allowing Obama to sidestep the constitutional requirement that treaties be ratified by two-thirds of the Senate — with voluntary pledges for specific emissions targets and aid to help poorer countries adapt to climate change. Nations would then be legally required to report progress toward their emissions targets at international meetings that would "name and shame" countries making slow or no progress, the Times reports. Lawmakers from both political parties say that no climate agreement requiring congressional approval could be reached in the near future. Republican leaders are expected to oppose the agreement being worked on by the administration and say it would be an abuse of executive authority.

25 Aug 2014: Health Care Savings Can Far
Outweigh Costs of Carbon-Cutting Policies

Implementing policies to curb carbon emissions dramatically cuts health care costs associated with poor air quality — in some cases, by more than 10 times the cost of policy implementation, according to new research published in Nature Climate Change. Policies aimed at reducing carbon emissions are as effective as laws targeting polluting compounds like ground-level ozone, also known as smog, and fine particulate matter, the MIT researchers say. An analysis of three climate policies — a clean-energy standard, a transportation policy, and a cap-and-trade program — found that savings from avoided health problems could recoup 26 percent of the cost of implementing a transportation policy, and up to to 10.5 times the cost of implementing a cap-and-trade program. A cap-and-trade program would cost roughly $14 billion to implement, whereas a transportation policy with rigid fuel-economy requirements could cost more than $1 trillion, according to the analysis.

Using data from the European Space Agency's CryoSat 2 satellite from 2011 to 2014, the team created the most detailed maps to date of ice elevations across Antarctica and Greenland, accurate to a few meters in height. The results reveal that Greenland alone is losing ice volume by about 375 cubic kilometers per year, doubling since 2009, the scientists report. Ice loss in the West Antarctic Ice Sheet has increased by a factor of three over the same period. Combined, the two ice sheets are thinning at the highest rate observed since altimetry satellite records began about 20 years ago, the study found. Data show that East Antarctica is gaining ice volume, but at a moderate rate that doesn’t compensate the losses on the continent's other side.

20 Aug 2014: Exporting Coal to Korea Could
Slash Emissions by 21 Percent, Analysis Says

Exporting U.S. coal to South Korean power plants could cut greenhouse gas emissions by 21 percent compared to burning it at less efficient U.S. plants, according to researchers at Duke University. The strategy could also generate more than $25 billion in economic activity in the U.S. and cut emissions of sulfur dioxide, nitrogen oxide, and particulate matter, the researchers say. For those benefits to occur, however, U.S. plants would need to replace the exported coal with natural gas, and South Korea must use the imported coal to replace dirtier sources of coal. South Korea's coal-fired power plants are newer and significantly more efficient than those in the U.S. — efficient enough to offset emissions associated with shipping the coal across the globe, the researchers say. However, they also caution that further studies are needed to assess the scenario's full environmental impacts, including water use, land use, and the degradation of vital habitats.
