Doyle Rice USA TODAY Published 11:03 p.m. UTC Jul 31, 2018 The fierce July that saw monstrous wildfires, record heat and unprecedented flooding across the globe was fueled by man-made climate change, scientists said – and these extremes are likely to become a fact of life. "Overall, globally, what we’ve been seeing is exactly what has been predicted for decades," said Noah Diffenbaugh, a geoscientist at Stanford University. Climate change is "upping the odds that when these heat waves happen that they’re hotter and more severe." Record-breaking heat waves and extreme rainfall are likely to become more common because the buildup of greenhouse gases – such as carbon dioxide from the burning of coal, oil and gas – is altering the atmosphere, according to the British journal Nature. Warmer air contains more water vapor and stores more energy; the increasing temperatures can also change large-scale atmospheric … [Read more...] about Global heat, fires and floods: How much has climate change fueled this hellish July?
What greenhouse gases contribute to global warming
The European Commission is leaving it up to member states to propose how much greenhouse gas reductions the EU's agricultural sector should achieve during the next EU budget period (2021-2027). It is giving national governments the freedom to come up with their own 'strategic plans' in which they explain how they will achieve the overarching European goals of the common agriculture policy (CAP). However, the common climate goals are worded so broadly that there is no assurance that the EU will indeed end up with climate action that is in line with the 2015 global 'Paris agreement' on climate. The 'EU specific objective' on climate that the commission laid down in the annex to a legislative proposal, presented on Friday (1 June), said: "Contribute to climate change mitigation and adaptation, as well as sustainable energy". The 'impact indicators' through which that objective should be achieved, said that greenhouse gas emissions from agriculture should be reduced, but not by how much. … [Read more...] about [Analysis] Commission bets on states to make farm policy ‘green’
For the last 18 months, Shawn Baker has eaten around 4lbs of steak every day. “I’ve got two rib-eye steaks waiting for me when I get off this call,” said the trained orthopaedic surgeon from Orange County, California. “It can be monotonous eating the same thing over and over again, but as time goes by you start to crave it.” The 6ft 5in bodybuilder in his 50s is one of a growing number of people experimenting with the “carnivore diet”, a regimen that involves eating only animal products like meat, offal and eggs and no plant-based foods. It’s an extreme version of the low-carb, high-fat ketogenic diet – which trains the body to run on fat rather than carbohydrates – that has become popular in recent years. Proponents of the diet say it reduces inflammation and blood pressure while increasing libido and mental clarity. Baker, who is nicknamed the “Carnivore King” and has amassed a cult following on social media, … [Read more...] about Eating 4lbs of steak a day: meet “carnivore dieters”
According to an international study, the tourism sector accounts for 8% of all anthropogenic emissions of CO2, and its carbon footprint could increase significantly due to a lack of regulations. EURACTIV’s partner le Journal de l’environnement reports. With low-cost flights and long distance holidays at discounted prices, tourism has become an activity responsible for a high level of greenhouse gas emissions (GHG), a trend which will continue to increase in the coming years if the demand for tourism continues to grow. This is not the first time the carbon footprint of tourism is evaluated. In 2007, the World Tourism Organisation (UNWTO) estimated the volume of carbon dioxide emissions caused by tourism to be 5% of the global carbon footprint, the equivalent of 1.3 billion tonnes of CO2 per year. Carbon emissions only Manfred Lenzen, a physicist from the University of Sydney and one of the authors of the study, believes the evaluation of the previous study to be undervalued … [Read more...] about Tourism’s growing contribution to GHG emissions
The Sahara Desert has grown significantly over the past century, and climate change is largely to blame, according to a new study. Analysing data collected since 1923, a research team examined the different factors that contributed to changes in rainfall in the Sahara region. They found the desert, already around the size of the US, had expanded by about 10 per cent over the period covered by this data. These results have implications for those living in the border region of the Sahara known as the Sahel, but the scientists noted that climate change-driven desertification is not a phenomenon unique to the Sahara. "Our results are specific to the Sahara, but they likely have implications for the world's other deserts," said Professor Sumant Nigam, an atmospheric and oceanic scientist at the University of Maryland and the senior author of the study. As the world’s population continues to grow, people in desert border regions cannot afford to lose more arable land to the … [Read more...] about World’s largest desert has grown even larger due to climate change
