Donald Trump appears to have taken a swipe at teenage climate activist Greta Thunberg, tweeting a video of an emotional Thunberg with an apparently sarcastic comment that she seems to be “very happy” and looking forward to a bright future. The president tweeted out a video with the comment showing visibly upset Thunberg as she delivered a blistering speech to world leaders at a United Nations summit.
An assessment backed by the world’s major climate science bodies has found commitments to cut greenhouse gas emissions must be at least tripled and increased by up to fivefold if the world is to meet the goals of the 2015 Paris climate agreement. The report, launched as leaders gather at a UN climate action summit in New York on Monday, says current plans would lead to a rise in average global temperatures of between 2.9C and 3.4C by 2100.
Thousands of young people are taking part in school strikes across Scotland and around the world to demand urgent action on climate change. They are the latest in a series of strikes started a year ago by 16-year-old Swedish schoolgirl Greta Thunberg. The protests have now spread across 150 countries, with Friday’s action billed as the largest so far.
Swedish climate change activist Greta Thunberg arrived in New York City on Wednesday after traveling across the Atlantic Ocean in a zero-emission yacht. She is attending several events in the city next month, including the U.N. General Assembly, U.N. Youth Summit on Climate and the Climate Action Summit. She stepped foot on land just after 4 p.m. and the 16-year-old then addressed reporters.
Cutting fossil fuel emissions alone won’t be enough to stop global warming, according to a new report released by UN scientists. The Intergovernmental Panel on Climate Change (IPCC) warns that agriculture, wide-scale forestry and other land use now accounts for almost a quarter of greenhouse gas emissions. The report, Climate Change and Land, says humans now use 72% of the planet’s ice-free surface to feed, clothe and support the growing population.
Successive ocean heat waves are not only damaging Australia’s Great Barrier Reef, they are compromising its ability to recover, raising the risk of “widespread ecological collapse,” a new study has found. The 2,300-kilometer-long (1,500 mile) reef has endured multiple large-scale “bleaching” events caused by above-average water temperatures in the last two decades, including back-to-back occurrences in 2016 and 2017. The new study, released Wednesday in the journal Nature, examined the number of adult corals which survived these two events and how many new corals they created to replenish the reef in 2018.
Canada is warming on average at a rate twice as fast as the rest of the world, a new scientific report indicates. Canada’s Arctic has seen the deepest impact and will continue to warm at more than double the global rate. Canada’s annual average temperature has increased by an estimated 1.7C (3F) since 1948, when nationwide temperatures were first recorded. The report suggests that many of the effects already seen are probably irreversible.
The “new abnormal” the world is facing from risks like nuclear war and climate change has led the symbolic Doomsday Clock to be frozen at the closest it has ever been to midnight. The clock, created by the Bulletin of the Atomic Scientists (BAS) in 1947, intends to warn of impending disasters. Its 2019 setting was announced on Thursday – staying in the same perilous position it was set at last year. The BAS has warned we are “normalizing a very dangerous world”.
Greenland’s ice is melting faster than scientists previously thought, with the pace of ice loss increasing fourfold since 2003, new research has found. This suggests surface ice is simply melting as global temperatures rise, causing gushing rivers of meltwater to flow into the ocean and push up sea levels. South-west Greenland, not previously thought of as a source of woe for coastal cities, is set to “become a major future contributor to sea level rise”, the research states.
An international team of scientists has developed a diet it says can improve health while ensuring sustainable food production to reduce further damage to the planet. The “planetary health diet” is based on cutting red meat and sugar consumption in half and upping intake of fruits, vegetables and nuts. The authors warn that a global change in diet and food production is needed as 3 billion people across the world are malnourished — which includes those who are under and overnourished — and food production is overstepping environmental targets, driving climate change, biodiversity loss and pollution.
