6 February 2019 carbon emissions Hazel Healy sketches out a radical scenario of carbon cold-turkey. In October 2018 the Intergovernmental Panel on Climate Change (IPCC) issued a stark warning: enact urgent measures to limit global warming within the next 12 years or irrevocably deplete the ecosystems that sustain human life on Earth. By way of remedy, the IPCC recommends that we reduce carbon dioxide (CO2) and other greenhouse gas emissions (GHG) to ‘net zero’ by 2050. This trajectory would give us a chance to limit warming to a maximum of 1.5 degrees Celsius – too hot for the coral reefs, due to be 90 per cent wiped out at that temperature – and no defence against the accelerating impacts such as extreme wildfires, heat waves and hurricanes, which are already upon us. Yet in December, news landed that after a period of levelling out, carbon emissions were set to rise steeply in 2018. Perhaps a more vertiginous transition would help … [Read more...] about What if…we reduced carbon emissions to zero by 2025?
Ways reduce global warming
PUBLISHED: 17:00 01 February 2019 Jo Malone Our world is precious and we are all looking for ways to reduce our impact on it. Picture Getty Images Archant How can I reduce my energy bill – and my carbon footprint?Our carbon footprint is the overall amount of greenhouse gas emissions, primarily carbon dioxide, that we, as individuals produce. Picture Getty ImagesWe’re trying to look after our world; cutting back on plastic, recycling, working to reduce the amount of food we waste and trying to use the car less. But we still have a long way to go.Our carbon footprint is the overall amount of greenhouse gas emissions, primarily carbon dioxide, that we, as individuals produce. It is the measure of our actual effect on the environment.We know that an increase in greenhouse gas emissions, and therefore in carbon footprint, is the primary event associated with climate change that has led to global warming.In Britain, our homes are the country’s … [Read more...] about How to reduce our carbon footprint
The global food system needs urgent reform, less meat consumption and more legumes, as three billion people worldwide are malnourished and food production is exceeding planetary boundaries, scientists have warned in a new report. The EAT-Lancet Commission, a platform of scientists, suggests a radical dietary shift that would prove beneficial to both human health and the environment. The report is the result of two years of collaboration among 37 experts from 16 countries. It highlights the fact that diets are inextricably linked to human health and environmental sustainability. “The human cost of our faulty food systems is that almost 1 billion people are hungry, and almost 2 billion people are eating too much of the wrong food,” the report says, adding that agricultural production is currently at its highest ever, but is neither resilient nor sustainable. While 3 billion people are malnourished, food production is exceeding planetary boundaries, driving climate change and … [Read more...] about Scientists call for radical change of diet to transform global food system
About 93 percent of excess heat trapped around the Earth by greenhouse gases that come from the burning of fossil fuels accumulates in the world's oceans. The UN Intergovernmental Panel on Climate Change (IPCC) says ocean warming has led to rising sea levels and contributes to increases in rainfall intensity, more violent storms and the destruction of coral reefs. Oceans warming - Interview with David Whitehouse Global Warming Policy Foundation UK 11/01/2019 Listen It is also a threat to biodiversity and one of the earth's major food supplies. "Ocean heating is a very important indicator of climate change, and we have robust evidence that it is warming more rapidly than we thought," said co-author Zeke Hausfather, a graduate student in the Energy and Resources Group at the University of California, Berkeley. Their report relied on four studies, published between 2014 and 2017 whose conclusions are based on measurements recorded by a fleet of some 4,000 floating robot monitors … [Read more...] about Our oceans may be warming quicker than previously thought
It was a year the world regressed – at least in terms of relations between states. Binding treaties were discarded, multilateral organisations were denigrated and usurped, international law was ignored, and the authority of the United Nations came under unprecedented challenge. The ideal, encouraged since 1945, of a global community making common cause to right the world’s wrongs faded. In 2018, the ties that bind frayed. Global rules-based order Donald Trump appointed himself public enemy number one of the global order. By his words and actions, he undermined the UN, the EU, the World Trade Organisation, the International Monetary Fund and the North American Free Trade Agreement. Trump questioned the usefulness of Nato and disrupted its meetings. He withdrew the US from the multilateral 2015 nuclear pact with Iran and, assuming global jurisdiction, vowed to punish anybody who disagreed. When the international court of justice in the Hague outlawed his Iran sanctions, he … [Read more...] about 2018: the year the global order frayed
