Giant clams and rising CO2: Light may ameliorate effects of ocean acidification on a solar-powered animal

Global climate change and ocean acidification pose a serious threat to marine life. Marine invertebrates are particularly susceptible to ocean acidification, especially highly calcareous taxa such as molluscs, echinoderms and corals. The largest of all bivalve molluscs, giant clams, are already threatened by a variety of local pressures, including overharvesting, …

Grantham Institute: Extend green subsidies to carbon capture

The UK and other EU countries should extend green subsidies, such as the Contracts for Difference scheme, to carbon capture and storage (CCS) technology, an influential think-tank has claimed. The Grantham Institute today (16 June) released a policy brief on CCS, which it claims is vital in limiting global warming …

IEA cautions against India's coal-dominated energy supply growth ahead of Paris climate summit

The International Energy Agency (IEA), the Paris-based energy think-tank for the Organization of Economic Cooperation and Development (OECD) countries, has said coal and other fossil fuels will continue to dominate India’s energy mix even as it lauded the government’s efforts to expand green energy sources through 2022. “India’s large (and …

Greenery makes kids brighter

- Study links open spaces to learning, memory A study from Spain that has for the first time linked green spaces in a city with cognitive abilities of primary school children may provide fresh scientific rationale for the Indian environment ministry's planned urban forestry scheme. Medical scientists at the Centre …

Environmental movement making a real impact in the US, study finds

The environmental movement is making a real difference in the US, according to a new research that shows states with strong green voices have significantly lower emissions of the gases that drive global warming. The study is one of the first to quantify the real impact of green politics on …

PN blasts ‘failure’ of traffic roadmap as air pollution increases

The Nationalist Party has hit out at the government for “failing” to stick to its roadmap to reduce traffic on the roads. “Traffic has now become the public’s biggest headache,” shadow transport minister Marthese Portelli said in a statement. “The government should implement its famous roadmap to reduce traffic, or …

Study: The Greener a State's Legislator, the Cleaner the Air

WASHINGTON — States where the congressional delegation votes greener tend to have air that's cleaner, spewing less heat-trapping gas, a new study finds. Researchers at Michigan State University studied decades of voting trends and greenhouse gas emissions state by state. They found a correlation between the voting records of a …

Climate Change: Global Food Supply May be Threatened by Cutting Carbon

Cutting carbon emissions is important in the face of climate change. As more and more carbon is released into the atmosphere, temperatures heat up. Now, though, scientists have warned that cutting these emissions may have indirect effects on the world's food supply. Previous studies have shown that climate change reduces …

Himachal sells first carbon credits through plantations

Shimla, June 15: The benefits of greening the degraded land in 10 districts of the state under the World Bank-funded climate change mitigation project under Kyoto Protocol have yielding results with Himachal selling its carbon credits for the first time for Rs 1.93 crore to Spain, with an assured amount …

Bridging the gap: improving the economic and policy framework for carbon capture and storage in the European Union

European Union countries need to significantly increase investments in carbon capture and storage and show much greater urgency and determination to develop and deploy the technology, according to a new report by the Grantham Research Institute on Climate Change and the Environment at London School of Economics and Political Science …

Diatom acclimation to elevated CO2 via cAMP signalling and coordinated gene expression

Diatoms are responsible for ~40% of marine primary productivity, fuelling the oceanic carbon cycle and contributing to natural carbon sequestration in the deep ocean. Diatoms rely on energetically expensive carbon concentrating mechanisms (CCMs) to fix carbon efficiently at modern levels of CO2. How diatoms may respond over the short and …

Climate Change: Plants Choke on too Much Carbon

It looks like even for plants, there can be too much of a good thing. Tree and flowers use carbon dioxide (C02) to make energy, absorbing the gas to help fuel the process of photosynthesis. For this reason, some experts have theorized that rising carbon levels will eventually promote plant …

Energy and climate change: world energy outlook special report 2015

A peak in global energy-related emissions could be achieved as early as 2020 and at no net economic cost says International Energy Agency in this new report . The world is moving towards a crucial climate change meeting in Paris in December 2015 (COP21). The negotiations there will be based …

Regional trends report on energy for sustainable development in Asia and the Pacific 2015

The Regional Trends Report on Energy for Sustainable Development in Asia and the Pacific will further accelerate knowledge-sharing within the region by providing an additional platform for member States to share their experiences, through case studies, regarding the energy sector and its future development. Through the Asia Pacific Energy Portal …

Development and climate policy synergies: insights from global modelling studies

India’s approach to climate policy is based on amplifying synergies between sustainable development and climate outcomes, or co-benefits. However, the evidence base for the magnitude of these synergies remains limited. This brief summarizes the result of global models, which provide strong evidence of complementarities between climate mitigation outcomes, reduced air …

European commission hails 'fiddled' Serbian climate pledge

Serbia’s new climate pledge for the coming UN summit in Paris has been hailed by the European commission as an “exemplary” step towards EU accession, even though official figures show that it involves a 15% increase in the country’s emissions by 2030. A Serbian headline pledge to cut emissions 9.8% …

Renewables fastest growing form of energy in 2014: BP

Renewable power was the fastest growing form of energy last year, with a record 6 percent of global power generation, in a year when energy consumption slowed sharply worldwide, BP said in an authoritative review. "Renewable energy used in power generation grew by 12 percent (last year)," said the BP …

Coral Reefs in Palau Defy Ocean Acidification

Coral reefs have been the subject of much research given the ongoing threats they are dealing with related to climate change. Ocean acidification, for one, is wreaking havoc on these delicate ecosystems, but a remarkable new study says that coral reefs in Palau may be able to defy the odds. …

Ethiopia to cut carbon emissions by two-thirds by 2030

Ethiopia has set targets to slash carbon emissions by two-thirds within the next 15 years, the most ambitious goal so far presented to an upcoming UN climate change conference in Paris. "Ethiopia intends to achieve its vision of becoming carbon-neutral, with the mid-term goal of attaining middle-income status," according to …

China emissions could peak 5 years earlier than expected

The nation's greenhouse gas emissions could peak at most five years earlier than expected, the annual blue book on China's low-carbon economic development said on Thursday. Greenhouse gas emissions are likely to peak between 2025 and 2030, according to the Global Low-carbon Economy Institute, which is a joint venture between …
