India's energy demand to double in next 25 years: ExxonMobil report

ExxonMobil also projected the country's GDP to rise from $2 trillion in 2014 to $9 trillion in 2040 India's energy demand is likely to almost double in next 25 years as the economy is estimated to expand to $9 trillion by 2040, US oil major ExxonMobil said in its Energy …

Gambia Set to Reduce GHG Emission From Key Sectors - Minister Jarju

Hon. Pa Ousman Jarju, the Minister of Environment, Climate Change, Forestry, Water and Wildlife has stated that The Gambia has tasked itself to reduce greenhouse gas (GHG) emission from key sectors to economy by 44.4% by 2025 and 45.4% by 2030 with domestic and international support. He lamented that human-induced …

Explaining road transport emissions: a non-technical guide

Road transport is an important source of both greenhouse gases and air pollutants. Despite improvements in vehicle efficiencies over past decades, today the sector is responsible for almost one fifth of Europe's greenhouse gas emissions. Emissions from vehicles also lead to high concentrations of air pollutants above EU standards in …

Mapping the gap: the road from Paris

To reach the level of investment in new renewable power generation needed to avert dangerous climate change, $12.1 trillion of investment will be needed over the next 25 years, which is $5.2 trillion above business-as-usual projections, a new report by Ceres and Bloomberg New Energy Finance concludes. Clean energy investment …

From agreement to action: mobilizing suppliers toward a climate resilient world

Following the historic international deal agreed at the UN climate conference, COP21, and the news from Davos that climate change is the world’s most impactful risk, major companies such as Dell, Unilever and Walmart are establishing the extent to which impending climate regulation will impact their business. However, half their …

Future cost-competitive electricity systems and their impact on US CO2 emissions

Carbon dioxide emissions from electricity generation are a major cause of anthropogenic climate change. The deployment of wind and solar power reduces these emissions, but is subject to the variability of the weather. In the present study, we calculate the cost-optimized configuration of variable electrical power generators using weather data …

Energy sector emits 70% of country's greenhouse gases

CO2 dominates the total GHG emissions and the energy sector comprising of electricity production, manufacturing industries, transport sector and fugitive emissions generates the maximum CO2 in the country. The energy sector in India is responsible for 71% of country's total greenhouse gas emissions (GHG's), a report from India to the …

The outlook for energy: a view to 2040

Global energy demand will increase 25 percent between 2014 and 2040, driven by population growth and economic expansion, ExxonMobil said in the 2016 edition of The Outlook for Energy. At the same time, energy efficiency gains and increased use of renewable energy sources and lower carbon fuels, such as natural …

Government urges India Inc to seize opportunities and meet obligations to move towards a low carbon economy

Indian Industry, which will play an important role in meeting the goals set by India's INDCs, will need to meet obligations even as they capitalise on new business opportunities. Mr Ashok Lavasa, Secretary, Ministry of Environment, Forest and Climate Change (MoEFCC), Government of India, said, it is equally a question …

U.S. appeals court declines to block Obama carbon emissions plan

In a big victory for the Obama administration, a U.S. federal court on Thursday rejected a bid by 27 states to block its Clean Power Plan, the centerpiece of its strategy to combat climate change by reducing carbon emissions from power plants. A three-judge panel of the U.S. Court of …

Future ocean hypercapnia driven by anthropogenic amplification of the natural CO2 cycle

Data-based projections suggest that the natural CO2 cycle could be amplified by up to ten times by 2100 in some oceanic regions if atmospheric CO2 concentrations continue to increase, which could detrimentally affect major fisheries.

Earth system commitments due to delayed mitigation

As long as global CO2 emissions continue to increase annually, long-term committed Earth system changes grow much faster than current observations. A novel metric linking this future growth to policy decisions today is the mitigation delay sensitivity (MDS), but MDS estimates for Earth system variables other than peak temperature (ΔT …

A framework to understand the transient climate response to emissions

Global surface warming projections have been empirically connected to carbon emissions via a climate index defined as the transient climate response to emissions (TCRE), revealing that surface warming is nearly proportional to carbon emissions. Here, we provide a theoretical framework to understand the TCRE including the effects of all radiative …

Carbon dioxide causing 'intoxication' of ocean fish sooner than expected

UNSW's Ben McNeil and Tristan Sasse explain how a rise in the oceans' CO2 levels could have huge implications for global fisheries and marine ecosystems. Ocean fish around the world risk becoming lost at sea if carbon dioxide concentrations in seawater continue to rise on current trajectories, a study from …

Considerations for reporting and disclosure in a carbon-constrained world

Hot on the heels of a historic climate deal in Paris the Carbon Tracker Initiative and the Climate Disclosure Standards Board, two non-profits who seek to promote transparency in relation to climate risk, will in Davos launch proposals for risk reporting by fossil fuel companies. The Paris accord confirmed the …

Bright start that ran out of gas

New Delhi: While car owners grumpily awaited their alternate day on Delhi roads during the recent 15-day driving experiment, there was one group that grinned happily every day. They were owners of cars that had a bright sticker saying 'CNG' stuck on their windshields. Cars running on compressed natural gas, …

Climatic modulation of recent trends in ocean acidification in the California Current System

Researchers reconstruct the evolution of ocean acidification in the California Current System (CalCS) from 1979 through 2012 using hindcast simulations with an eddy-resolving ocean biogeochemical model forced with observation-based variations of wind and fluxes of heat and freshwater. Researchers find that domain-wide pH and ${{\rm{\Omega }}}_{\mathrm{arag}}$ in the top 60 …

Carving out a model for enhancing CO {-2} sinks

In the Paris Summit (United States Conference on Climate Change), held during December 2015, India has strongly advocated climate justice and adhered to the principles of equity and common but differentiated responsibilities (CBDR) on the issue of climate change actions. Intended nationally determined contributions (INDCs) for the period 2021-30 were …

Warming may delay next ice age

Global warming is likely to disrupt a natural cycle of ice ages and delay the onset of the next one until about 1,00,000 years from now, scientists said on Wednesday. In the past million years, the world has had about 10 ice ages before swinging back to warmer conditions. In …
