A McGill-led study suggests that Earth's natural forces could substantially reduce Antarctica's impact on rising sea levels, but only if carbon emissions are swiftly reduced in the coming decades.

An interesting potential ramification of the devastating symptoms of climate change we are witnessing now: "The crisis facing the continent has widespread implications. More than 40 nations are signatories of the Antarctic Treaty’s environmental protocol, which is supposed to shield it from a host of different threats, with habitat degradation being one of the most important. The fact that the continent is now undergoing alarming shifts in its ice covering, eco-systems and climate is a clear sign that this protection is no longer being provided. “The cause of this ecological and meteorological change lies outside the continent,” added Siegert. “It is being caused because the rest of the world is continuing to emit vast amounts carbon dioxide. “Nevertheless, there is a good case for arguing that if countries are knowingly polluting the atmosphere with greenhouse gases, and Antarctica is being affected as a consequence, then the treaty protocol is being breached by its signatories and their behaviour could be challenged on legal and political grounds. It should certainly make for some challenging meetings at the UN in the coming years.”" https://lnkd.in/e7vrU38q #ClimateChange #TippingPoints #SeaIce #PolarIce

Whatever happens, we know huge change is coming. How we live. Where we live. How we travel. What we consume. How much we can consume.

Unlocking the Secrets of the Pacific Ocean A recent study has revealed insights from a 600-year-old coral in Fiji, showing how Pacific Ocean temperatures have changed since 1370. This ancient coral provides a window into the past, revealing natural climate variability and the significant impact of modern global warming. Preserving our oceans and their ecosystems is more crucial than ever. #ClimateChange #Sustainability #OceanConservation #Natpak #EnvironmentalImpact #CoralReefs #ClimateResearch #GlobalWarming #EcoConscious #MarineScience #SustainableFuture #SustainablePackaging https://lnkd.in/gsqRHuHN

By releasing Sulfur dioxide molecules into the atmosphere, especially around the #Equator, we could slow the rate of ice loss in #Antarctica. The West Antarctic Ice Sheet is melting at a rate 3 times that of the past and contains enough water to raise global sea levels by 5.3 metres. A new study has found that by releasing Sulfur dioxide into our atmosphere, we can: 🌎 Battle #GlobalWarming ❄ Reduce Ice Loss in Antarctica 🌊 Reduce #SeaLevelRise Read more here: https://lnkd.in/ewPHgfFj #environmentaloptimism #environment #climate #climatechange #climatecrisis #climateemergency #climateaction #ecosystems #ocean #carbonemissions #savetheplanet #earth #sustainability #nature

Scientists are sounding the alarm about rising global temperatures and the impacts they have on biomes on land and in the sea. Global ocean surface temperatures have soared again following nine consecutive “hottest months” records in a row. This series of events is causing irreparable damage to the ocean, our planet’s largest natural carbon sink, and threatens yet another “mass coral bleaching” event, which can lead to the collapse of fragile reef ecosystems. The ocean cannot sustain prolonged bleaching periods and will continue to deteriorate unless significant changes are made. Reuters https://reut.rs/3vbYhQH #oceans #climatechange #coralbleaching

'The tipping points at risk include the collapse of big ice sheets in Greenland and the West Antarctic, the widespread thawing of permafrost, the death of coral reefs in warm waters, and the collapse of atmospheric circulation in the North Atlantic. Unlike other changes to the climate such as hotter heatwaves and heavier rainfall, these systems do not slowly shift in line with greenhouse gas emissions but can instead flip from one state to an entirely different one. When a climatic system tips – sometimes with a sudden shock – it may permanently alter the way the planet works. Scientists warn that there are large uncertainties around when such systems will shift but the report found that three more may soon join the list. These include mangroves and seagrass meadows, which are expected to die off in some regions if the temperatures rise between 1.5C and 2C, and boreal forests, which may tip as early as 1.4C of heating or as late as 5C.' https://lnkd.in/eCG2Rtek

Since the Russian war of aggression in Ukraine, climate research in the Arctic has lost access to crucial data from Siberia, which makes up half the land area of the Arctic. This gap leads to a bias that makes climate predictions very difficult. #Arctic #Russia #Siberia #research #Interact #climatechange #climate
Without Siberia, it’s hard to keep track of Arctic changes

📢 Exciting Research Update! 📢 New research published by Antarctic Research Centre - Te Puna Pātiotio scientist Dr Shaun Eaves and colleagues shows how past changes in a major global ocean current has affected climate in New Zealand and Tasman Sea. Combining evidence from marine sediment cores, glacial landscapes, and glacier and climate modelling, the team show that changes in Atlantic Meridional overturning circulation (AMOC) can have significant impact on climate in the SW Pacific region. Modern observations show AMOC is weakening and may represent undergo severe changes in the future. This new research suggests any future changes could accelerate recent warming trends in the southern hemisphere. Summary overview published in The Conversation Australia + NZ: https://lnkd.in/gjH4v4mG #VictoriaUniversityofWellington #climatechange #theconversation #publishedreseach #AMOC
Weakening or collapse of a major Atlantic current has disrupted NZ’s climate in the past – and could do so again
