Climate Change

Posts about global warming, environmental changes, and their effects on Earth

[Answer: Yes UNEP always over estimates - reality is we are on track for 1.5 C - will collate the posts into a proper debunk - meanwhile see links in this post - to post:] ◀ Has this been talked about yet?
Reassurance and tips for those new to heat waves - humans have lived at 40 C and even 50 C for millennia - and you can adapt - local heat anomalies that occur at the same time as local cold anomalies elsewhere - as expected at current global warming levels and not sudden warming
Super El Nino
[Answer: No it is NOT valid - we are doing lots to stop and reverse biodiversity loss - and there is no risk of a mass extinction - we have already done a lot to STOP one that would have taken A THOUSAND YEARS to play out - and there are many species alive today such as the blue whales that only survived because in the past we stopped killing them and moved to conservation insteasd - and we are doing this more and more - to post:] ◀ Has anyone seen this video? Is what he says about Climate Change and collapse valid?

[Answer: The Orange cup coral IS an invasive species - but mainly confined to ship wrecks, oil rigs and so on - does well in shade as it doesn't need sunlight - it is not an especially serious risk to shallow sea warm water corals though it's found in shady spots in one important coral reef near Florida - Flower Garden Banks - and they monitor it - to post:] ◀ Coral Reefs, Invasive Species
[Answer: Yes we do need to mine new materials for the renewables revolution this century and next - recycling can't provide everything - but know how to do it - with climate smart mining and net zero inititives e.g. for copper and nickel - Some recycled indefinitely like water, wood, cotton, salt - some almost inexhaustible - and over timescales of many centuries to millennia some may need to be substituted for others - challenges ARE similar to what nature faces - when it uses solar energy to concentrate resources for a tree or plant to use to grow - to post:] ◀ Limits to recycling

[Answer: No possibility of collapse - we can feed everyone on all secenarios - huge and growing surplus every year - hunger and malnutrition is because of hard to solve social / economic / political issues not world food capacity - and no possibility that the stronger economies could be unable to buy enough food for their countries - weaker economies rely on World Food Program and CERF etc - and realistic to aim for zero hunger by 2030 though unlikely to achieve it - to post:] ◀ Ecological Economist William on on overshoot and collapse

Collapse risk
[Answer: No the Paris agreement path to 1.5 C was for net zero by 2050 - but renewables is growing far faster than anyone expected and you don't see this on the emissions curve yet as it is exponential - to post:] ◀ Is this graph right?
[Answer: No this is not near future or in your lifetime - Thwaites glacier melt only adds 2 cms out of an extra 38 cm by 2100 on low emissions - all global ice melt combined can reach 2 meters by 2150 in a super fast high end story line for 1.8 C - 3 m for NY - but that's unlikely and 125 years away - to post:] ◀ “Doomsday” glacier?
[Answer: No the fossil fuel industry CAN'T trick scientists in peer reviewed journals - or IPCC which does a systematic review - they DID do public relations in the 1970s that claimed no global warming when their own scientists PUBLISHED research supporting warming - and Shell and BP continue to publish yearly projections - but these OVER ESTIMATE the future oil demand, the opposite of your tweet - not a surprise to be biased in a direction that encourages investment in the oil industry - to post:] ◀ Spiralling over this climate tweet I need it debunked immediately
New simple calculator you can try for yourself to show how fast solar power can cut emissions if it continues even at the slowest growth rate of the last decade of 21% / year impact on emissions - which so far nobody is modelling as far as I can see - preparation for my new substack
