Natural solutions such as tree planting, protecting peatlands and better land management could account for 37% of all cuts needed by 2030, says study

October 17, 2017 — Planting forests and other activities that harness the power of nature could play a major role in limiting global warming under the 2015 Paris agreement, an international study showed on Monday. Continue reading Regreening the planet could cut as much carbon as halting oil use – report

Our cities need fewer cars, not cleaner cars

Electric cars won’t eradicate gridlocks and air pollution, but carbon footprints could be cut by favouring pedestrians, cyclists and mass transit

October 16, 2017 — The spectre of our cities choking with unhealthy air has prompted numerous governments to mandate a transition to electric cars. Their concerns are well founded, even if their proposals fall short of what is needed. Continue reading Our cities need fewer cars, not cleaner cars

Repealing the Clean Power Plan (CPP) was a campaign promise by President Donald Trump and follows his decision in June to withdraw from the 2015 Paris agreement

WASHINGTON DC, USA (Oct. 11, 2017) — The head of the United States Environmental Protection Agency signed on Tuesday, October 10, a draft decision to roll back Obama-era measures to counter climate change. Continue reading US environment chief signs draft rollback on Obama climate plan

Carbon emissions from warming soils could trigger disastrous feedback loop

26-year study reveals natural biological factors kick in once warming reaches certain point, leading to potentially unstoppable increase in temperatures

October 5, 2017 — Warming soils are releasing more carbon into the atmosphere than previously thought, suggesting a potentially disastrous feedback mechanism whereby increases in global temperatures will trigger massive new carbon releases in a cycle that may be impossible to break. Continue reading Carbon emissions from warming soils could trigger disastrous feedback loop

Ships’ fumes a trigger for more lightning strikes

Exhaust emissions blamed for changing storm clouds and generating lightning nearly twice as often directly above busy shipping lanes than in ocean areas nearby

September 19, 2017 — Thunderstorm aficionados, if you really want to see some action then get yourself aboard a cargo ship. A new study has shown that lightning strikes occur nearly twice as often Continue reading Ships’ fumes a trigger for more lightning strikes

Ambitious 1.5C Paris climate target is still possible, new analysis shows

Goal to limit warming to 1.5°C to avoid the worst impacts of climate change was seen as unreachable, but updated research suggests it could be met if strong action is taken

September 18, 2017 — The highly ambitious aim of limiting global warming to less than 1.5°C remains in reach, a new scientific analysis shows. Continue reading Ambitious 1.5C Paris climate target is still possible, new analysis shows

Enough tiptoeing around. Let’s make this clear: coal kills people

Burning more coal, knowing what we know, is a deliberate act of arson. We must urgently come to grips with this fact and reconnect with nature and our communities

September 17, 2017 —Coal kills people. This isn’t even slightly scientifically controversial. From the mines to the trains to the climate disruption; from black lung to asthma, heat stress to hunger, fires to floods: coal is killing people in Australia and around the world right now. Continue reading Enough tiptoeing around. Let’s make this clear: coal kills people

Mismanagement alleged against only company interested in Liddell power station

Environmental law group has accused Delta Electricity of underreporting emissions at its Vales Point power station and breaching licence conditions

September 7, 2017 — The only Australian company with a stated potential interest in buying and keeping AGL’s ageing Liddell coal-fired power station open beyond 2022 is facing a number of allegations of environmental mismanagement. Continue reading Mismanagement alleged against only company interested in Liddell power station

Denying Hurricane Harvey’s climate links only worsens future suffering

Homes are surrounded by floodwater after torrential rains pounded Southeast Texas following Hurricane and Tropical Storm Harvey on August 31, 2017 in Sugar Land, Texas.

The variables in the climate change formula are mitigation, adaptation, and suffering. Denying the problem loads up on the suffering

September 5, 2017 — Human-caused climate change amplified the damages and suffering associated with Hurricane Harvey in several different ways. First, sea level rise caused by global warming Continue reading Denying Hurricane Harvey’s climate links only worsens future suffering

Volcanic eruptions triggered global warming 56m years ago, study reveals

Scientists say one of the most rapid periods of warming in Earth’s history was due to gradual release of CO2, warning current levels of emissions were even higher

August 30, 2017 — A dramatic period of global warming 56 million years ago that saw temperatures climb by up to five degrees and triggered extinctions of marine organisms was down to volcanic Continue reading Volcanic eruptions triggered global warming 56m years ago, study reveals
