Should climate change be taught in mainstream schools? Several legislators have proposals

Andrew Cao, who graduated from Middlesex School in Concord earlier this month, said he has always been a conservationist. Involved in his school's environmental club, he recalled an initiative last year where members tried a "meatless Monday" menu, which did not achieve the results they had hoped for. "For lunch one day, we had the restaurant staff cut the meat completely," he explained. “But a lot of students hated it because they are so used to eating meat. They didn't quite understand that we were trying to point out the impact on the environment." (Taylor Brokesh)

Bioenergy with carbon capture and storage: Towards net zero emissions

Bioenergy with carbon capture and storage (BECCS) is a promising technology that has the potential to help the world achieve net zero emissions. As the global community grapples with the urgent need to reduce greenhouse gas emissions and limit global warming, BECCS offers a way not only to generate energy from renewable sources, but also to remove carbon dioxide (CO2) from the atmosphere. The BECCS concept involves the use of biomass such as plants and organic waste as a fuel source for energy production. During the combustion process, the emitted carbon dioxide is captured and stored underground, preventing it from entering the atmosphere. This process effectively creates a negative carbon footprint as the biomass absorbs CO2 during growth and the subsequent capture and storage of emissions results in a net removal of CO2 from the atmosphere.

Battle lines harden over Big Oil's role at Dubai climate talks

Inevitable tension surrounds this year's November climate talks under the auspices of the United Nations: They will be held in the oil-rich United Arab Emirates, and the most important role in the negotiations will be played by the man who heads the nation's oil company. Chief Executive Sultan al-Jaber and other emirate officials have said they have a "game-changing" plan to combat climate change by welcoming oil and gas companies from around the world to participate more in talks. In other words, invite the producers of the fuels that cause most of the global warming to be key players in developing a plan to slow warming. (Max Bearak)

What is climate colonialism? What you should know about why climate change and colonialism are linked.

you expect to see them together in whatever context, but climate change and colonialism are inextricably linked. We will look at why this is so and why considering the impact of historical and ongoing colonial practices is so crucial in the climate change movement. Let's start with a quick refresher on what colonialism means before we get into what it has to do with climate change. (GLOBAL CITIZEN)

Climate change is making trees bigger, but also weaker

As global temperatures rise, trees in colder regions benefit from an extended growing season. A longer growing season results in thicker rings and, as a result, higher overall wood production. This article is part of a series La Conversation Canada  The Boreal Forest: A Thousand Secrets, A Thousand Dangers. However, studies suggest that longer growing seasons contribute to the weakening of the wood, making the trees structurally weaker. Poor wood quality makes logs break more easily.

The health response to climate change is heating up

A new strategy that examines the link between health care and climate change – a first for the Australian federal government – is now available to the public. Citing a recent report by the Intergovernmental Panel on Climate Change, which projects global warming of 1.5°C above pre-industrial levels by 2030, the consultation paper warns that "climate hazards and their impacts on health and ecosystems will inevitably increase".

El Niño is back. Here's what this phenomenon means for extreme weather and global warming.

The global weather phenomenon marks when the waters of the Pacific Ocean become much warmer than usual. After three years of cold La Niña weather, the US National Oceanic and Atmospheric Administration (NOAA) announced on Thursday that El Niño is now underway. “El Niño is commonly associated with record temperatures globally. Whether it will happen in 2023 or 2024 is not yet known, but I think it is more likely than not," says Carlo Buontempo, director of the EU's Copernicus programme. Climate Change Service.

Climate change: Prepare for the second coming of carbon sequestration

For those who have watched the transition in energy over the past several decades, there is one technology that is considered a serious industry: carbon capture and storage. About a decade ago, it was still seen by many as the best hope for decarbonizing the world's energy systems. CCS was the "Google and Intel of the energy world," declared the Atlantic magazine in a 2010 cover story that predicted solar and wind power would never exceed 10 percent of the energy supply. In the following decade, it was renewables that boomed, while CCS went bankrupt.

Climate Change Adaptation: Least Developed Countries Fund (LDCF) and Special Climate Change Fund (SCCF)

Climate change poses a growing threat to all human and natural systems on our planet. International efforts are intensifying to prepare for rising sea levels, higher temperatures, worsening droughts, frequent flooding and other impacts that may affect water resources, crop yields and the health of people and ecosystems. Adaptation measures are urgently needed in vulnerable developing countries to secure development gains and promote resilient growth. (GEF)

Climate and sustainable energy

In the face of climate change, the scientific community, especially in the IPPC Sixth Assessment Report published in 2022, in confirming the key role played by cumulative greenhouse gas emissions and in the collective achievement of carbon neutrality. While we must aim to drastically reduce the world's use of fossil fuels if we are to limit global warming, there is no single path to achieving this goal.

Geoengineering without decarbonisation will not solve the climate crisis

In April, a huge mass of hot air settled over the western Mediterranean, causing a record heat wave in Algeria, Morocco and Spain. In some places, thermometers reached more than 20 degrees C more than expected for this time of year. The weather was so extreme that scientists quickly concluded that it would not have been possible without human-caused climate change. Climate change attribution has made great strides over the past decade. Scientists are now able to say with increasing confidence that extreme weather events were more likely because of higher concentrations of carbon dioxide in the atmosphere. The academic papers published in this area are complex, many of them mathematical and almost completely incomprehensible to most people. But the main message that comes out of this work is very simple: Climate change, once thought to be a distant threat, is happening now, and it's killing people. (James G. Dyke)

The cruise industry is on a course for climate disaster

O future archaeologists, mega cruise ships may be some of the strangest artifacts of our civilization – these goliaths of mass-engineered pleasure, armed with hanging water slides and phalanxes of umbrellas. Looking at one of these, you might get the impression that cruise lines are trying to impress their customers into having a good time. We built battleships for pleasure, roamed the world's oceans, and fished for fun. (ALEJANDRO DE LA GARZA)

Yes, you can reduce carbon in ads without affecting cost or performance

Private jets, cars, cow farts – we all know things that are really bad for the planet. And then there's digital advertising. A recent report from Purpose Disruptors suggests that advertising adds a further 32 % to the annual carbon footprint of each person in the UK, with a significant chunk coming from the significant computing power required to power online advertising campaigns. It means a typical advertising campaign emits around 5.4 tonnes of carbon dioxide – more than half of what the average UK consumer produces in a year. (Claire Gleeson-Landry)

El Niño combined with global warming means big changes for New Zealand's weather

According to the US National Oceanic and Atmospheric Administration, El Niño is officially here, and with it comes a change from the La Niña weather New Zealand has experienced over the past three years. In particular, the shift from prevailing north-easterly to south-west regions means that New Zealand is one of the few countries to experience cooler conditions during El Niño. But what "flavor" will this El Niño have? Time will tell, but El Niño has been lurking for some time. Evidence of its imminent arrival could be seen last year in subsurface ocean temperatures, with warm water accumulating in the Coral Sea and western tropical Pacific. Moreover, it was overdue. When La Niña finally gave up in March of this year, global sea surface temperatures were suddenly the highest on record (Figure 1 below) as the tropical Pacific suddenly began to warm.

The UAE is eyeing salty, muddy mangroves to fight climate change

Against the heat, urbanization and sand of the United Arab Emirates, the calm, muddy waterways of the Gulf state's coastal mangroves are being restored and replanted in an ambitious fight against climate change. Tropical mangrove forests are complex ecosystems anchored around mangrove trees that thrive in inhospitable hot, muddy and salty conditions. They protect coastal communities from storms and floods, host diverse and endangered species, and can mitigate climate change by sequestering atmospheric carbon. withstand extremely high salinity and super high temperatures," said Hamad al-Jailani, a scientist at Environment. (Abir Ahmar and Amr Alfiky, REUTERS)

Greenhouse gas emissions reached record high values

Greenhouse gas emissions have reached a 'grand peak' - and are causing unprecedented rates of global warming, the study warned. Scientists have calculated that 54 billion tons of carbon dioxide have been emitted annually over the past decade. Human-caused global warming has continued to increase at an "unprecedented pace" since the last major assessment of the climate system, published two years ago, according to 50 leading scientists. Failure to cut emissions means the Earth has a 50 percent chance of exceeding the 2.7°F (1.5°C) global warming limit set by the 2015 Paris Agreement within less than five years. In the journal Earth System Science Data, scientists have revealed how key indicators have changed since the publication of the IPCC Sixth Working Group 1 report in 2021.
