The Paris Climate Deal Is Now in Force. What Comes Next?
December 4, 2016 09:07 PM - Steve Williams, Care2
The Paris Agreement was hailed as a turning point for world governments tackling climate change, and it has now come into effect. What does this mean for the world — and where do we go from here?
On Friday, November 4, the Paris Agreement went into effect, meaning that the agreement made last year by nearly 200 international delegates must now be honored. To recognize the consensus coming into force, the United Nations stated that it is a moment to celebrate – and to take concerted action.
“We remain in a race against time,” UN Secretary General Ban Ki-moon emphasized. ”Now is the time to strengthen global resolve, do what science demands and seize the opportunity to build a safer, more sustainable world for all.”
CharIoT on course to deliver healthier homes and lower energy bills
December 2, 2016 11:46 AM - Engineering and Physical Sciences Research Council
Successful trials of CharIoT, a unique new system that simultaneously records temperature, humidity and energy use in the home, have opened the way for low-income households to save money while reducing risks to their health.
Harnessing Internet of Things technology, the system generates easy-to-use data that can help local authorities, housing associations, energy suppliers, health authorities and others to target and tailor the energy advice they give to vulnerable people.
As well as revealing under- or over-heated parts of a home, CharIoT enables energy advisors to pinpoint where and why damp or mould may pose a problem. They can then suggest, for example, ways of using heaters more efficiently and cost-effectively, blocking draughts and eliminating dampness through better ventilation.
How Solar power is bringing food security to Africa
November 25, 2016 11:54 AM - Joe Ware , The Ecologist
Malawi is one of the poorest countries in the world. Ninety per cent of Malawians live in rural areas; agriculture makes up 80 per cent of the labour force and 80 per cent of its exports. With so many people reliant on growing things from the ground, disruptions to the climate threatens the wellbeing of an entire nation.
For centuries Malawian farmers have learned the patterns of the seasons - when to plant their seeds in order to capture the rains that watered the ground and brought forth food to eat and sell. But this life-saving knowledge is becoming worthless, as rainfall patterns are distorted by a changing climate and the El Nino weather event, which this year created the worst food crisis in 25 years.
Concrete jungle functions as carbon sink
November 22, 2016 07:03 AM - UCI News
Cement manufacturing is among the most carbon-intensive industrial processes, but an international team of researchers has found that over time, the widely used building material reabsorbs much of the CO2 emitted when it was made.
2016 Temperatures Measure 1.2 Degrees C Above Pre-Industrial Levels
November 14, 2016 01:44 PM - Yale Environment 360
This year is on track to become the hottest year on record, with global temperatures measuring 1.2 degrees Celsius (2.2 F) above pre-industrial levels, according to the World Meteorological Organization(WMO).
Study reveals 82% of the core ecological processes that underpin ecosystems and provide services to people are now affected by climate change
November 14, 2016 10:20 AM -
Most studies of global climate change attempt to predict what might happen to the Earth as temperatures rise in future. A new study representing an international collaboration by ecologists and conservation biologists shows that global changes in climate have already impacted every aspect of life on Earth, from genes to entire ecosystems. It was published in the prestigious journal Science on November 10, 2016.
The research team, led by the University of Florida and with participation from the University of Hong Kong, showed that of a total of 94 ecological processes evaluated globally, 82% of them showed evidence of impact from climate change. Land, freshwater and marine ecosystems and species have all been all affected, and consequential impacts on people could range from increased pests and disease outbreaks, to unpredictable changes in fisheries and decreasing agriculture yields.
Climate, human influence conspired in Lake Urmia's decline
November 10, 2016 10:01 AM - International Institute for Applied Systems Analysis
The dramatic decline of Iran’s Lake Urmia—once the second-largest hypersaline lake in the world—has both direct human and climatic causes, according to a new study published in the Journal of Great Lakes Research. The study was the first to compare the relative impact of climate and water management on the water flowing into the lake.
Solar Cells Get Boost with Integration of Water-Splitting Catalyst onto Semiconductor

Scientists have found a way to engineer the atomic-scale chemical properties of a water-splitting catalyst for integration with a solar cell, and the result is a big boost to the stability and efficiency of artificial photosynthesis.
Led by researchers at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab), the project is described in a paper published this week in the journal Nature Materials.
New Delhi Air Pollution Reaches Highest Level In 20 Years
November 7, 2016 03:20 PM - Yale Environment 360
Indian officials declared an emergency in New Delhi over the weekend as the capital city entered its second week with air pollution levels as high as 30 times above World Health Organization guidelines, several news outlets reported.
Construction sites have been closed, operations at a coal-fired power station halted, diesel generators stopped, and officials are preparing to reinstate traffic restrictions, all to reduce smog levels across the city, which have reached their highest levels in 20 years. Officials say field burning on nearby farmland and fireworks from the recent Diwali festival helped worsen the smog conditions.
Record hot year may be the new normal by 2025
November 7, 2016 09:37 AM - Australian National University
The hottest year on record globally in 2015 could be an average year by 2025 and beyond if carbon emissions continue to rise at the same rate, new research has found.
Lead author Dr Sophie Lewis from the ANU Fenner School of Environment and Society said human activities had already locked in this new normal for future temperatures, but immediate climate action could prevent record extreme seasons year after year.
