An estimated 80% of your phone’s negative impact on the environment happens before you take it out of the box. One smartphone contains more than 70 raw materials and more than 50 metals. 200g phone involves extracting resources from over 200kg of raw materials. @backmarketofficial.bsky.social

We join the global community in mourning the passing of Dr Dame Jane Goodall, renowned primatologist, conservationist, and UN Messenger of Peace. Her groundbreaking scientific work transformed our understanding of nature and will continue to inspire generations. #JaneGoodall

#ClimateChange 🌡️ is exceptional and caused by human greenhouse gas emissions 🏭 We are causing #globalwarming 10 times faster than past natural changes We are taking Earth’s 🌎 climate beyond natural limits, with carbon dioxide & temperatures levels not seen for 3 million years

Make Science Great Again 🧠 When Truth Becomes a Threat, Science Becomes Resistance Scientists silenced 🔇 Research closed 🔒 Data destroyed 🧨 Disinformation spreading. We must defend truth, empower scientists & counter denial @wedonthavetime.bsky.social www.wedonthavetime.org/makescienceg...

#Earthday2025 Only the ignorant & stupid deny #climatechange is real It should not be political UK Prime Minister Margaret Thatcher understood the science and told UN that we have a duty to solve this crisis in 1989. It is now 2025 and we have leaders that just don’t care

#EarthDay2025 Gaylord Nelson - US Senator & Governor 55 yrs ago founded Earth Day 🌎 creating a new wave of environmentalism He says we have the power to #saveourplanet Are we able? Yes Are we willing? That is the unanswered question 🙄 Especially with the growing #climatechange denial

Fossilised giant sequoia 🌲trees at Sigri on the west of Lesbos. 20 million years ago a sequoia forest 🌲 was in Greece. Sequoia are now found in wet temperate California 🌧️ This tree stood over 100 m tall Fieldwork with brilliant @uclgeography.bsky.social students studying past #climatechange

And still the best 🤣 and Max is right it works as a communication tool - for example Jo Brand and I made it on to Breakfast TV to talk about climate change 👍🤣

The Seven Stages of climate denial: 1. It's not real 2. It's not us 3. It's not that bad 4. We have time 5. It's too expensive to fix 6. Here's a fake solution 7. It's too late: you should have warned us earlier Trolls use all of these stages to deny reality of #climatechange on Ex-Twitter 🤣

12 months of negotiations, 2 weeks of intense negotiations at COP29 & overrun of 33 hours & all we get is $300 billion per year pledge by 2035 to help developing countries transition away from fossil fuels. No where near the $1.3 trillion requested or $3 trillion per year that is actually needed

Prof Mark Maslin @profmarkmaslin.bsky.social · 23/11/2024
COP29 new text headline figure is $300bn by 2035 to help poor countries transition away from fossil fuels. Developed countries should “take the funding lead” - allows countries such as China/ India to contribute Call for at least $1.3 trillion by 2035 but in the weakest of UN diplomatic language

Prof Mark Maslin @profmarkmaslin.bsky.social · 22/11/2024
Last official day of COP29 - and the draft text is weak and has many omissions. 1. Developing countries want $1.3 trillion in climate finance - at the moment there is only $250 billion by 2035. 2. No mentioned of the transition away from fossil fuels - EU fighting hard to get this restated. 🙄

Prof Mark Maslin @profmarkmaslin.bsky.social · 21/11/2024
COP29 is supposed to be the finance COP But draft text is very vague and not real financial commitments. African nations are insisting that China and India are no longer developing nations and should contribute money to the green transition and loss and damage. #climatechange @cop29.bsky.social

ClimateChange: how bad could the future be if we do nothing? #ClimateCrisis is real and happening now. There is still everything to fight for - reducing emissions now means we could stay below 2˚C. Here is my handy table of global warming impacts and article ⬇️ theconversation.com/climate-chan...

How can past COP meetings help shape future environmental discourse? Read a short history of the successes and failures of previous COP summits in my article: bit.ly/3Z7a2UX Explains why the net zero has become deeply ingrained in politics and commerce. And why COPs cannot solve everything

#ClimateChange 🌡️ 1.5°C exceptional warming is caused by human GHG emissions 🏭 We are causing #globalwarming 10 times faster than past natural changes We are taking Earth’s 🌎 climate beyond natural limits, with CO2 & temps levels not seen for 3 million years. Net zero now!
