Battling climate change: Streamlining carbon offsetting could be Australia's best bet to cut emissions

Offsetting refers to reducing emissions or removing carbon dioxide from the atmosphere in one place to make up for emissions in another

India will reduce emissions in Antarctica, protect environment: Union Minister Jitendra Singh

India has two active research stations: Maitri (commissioned in 1989) at Schirmacher Hills, and Bharati (commissioned in 2012) at Larsemann Hills in Antarctica.

Wildfires emitted record levels of more than 2.5 billion tonnes of CO2 in July and August alone

Even the Arctic Circle was on fire, releasing some 66 million tonnes of CO2 from June through August, with nearly a billion tonnes from Russia as a whole over the same period.

For India to reach net-zero by 2050, the country needs to allocate 2.5 percent of its land for clean energy installation

The study by Institute for Energy Economics and Financial Analysis (IEEFA) notes the potential for land-use conflict to arise over renewable energy installations, even in sparsely populated areas.

Failure to curb emission has put world on catastrophic pathway to 2.7-degrees of heating: UN chief

"Failure to meet this goal will be measured in the massive loss of lives and livelihoods," UN chief Antonio Guterres said.

How much of the world’s energy comes from fossil fuels? Can renewables replace it all?

Fossilisation of trees moved enormous amounts of carbon from the air to underground, leading to a decline in atmospheric CO₂ levels

Most coal, oil and gas reserves need to stay underground if Paris agreement goals are to be met

Burning fuels for electricity, transportation and other uses are the chief driver of climate change, pulling long-buried carbon in fossil fuels out of the ground and depositing that carbon into the atmosphere as carbon dioxide.

Value of nature: What is the cost of the trees in the Gabon forests that suck in carbon dioxide

"If a tree is standing it's worth nothing, if you cut it down it's worth something, but that's useless for the planet," said Carlos Manuel Rodriguez, head of the Global Environment Facility.

Use of clean hydrogen could lead to higher greenhouse gas emissions than coal

While blue hydrogen does contain some emissions, the study notes that energy also is needed in the carbon-capture process hence provides no benefit.

Leaders and experts speak up after the release of the new IPCC report

The report is titled Climate Change 2021: the Physical Science Basis and is the most detailed assessment of climate science ever undertaken.
