Since the eight earliest Long Count dates appear outside the Maya homeland, [12] it is generally believed that the use of zero in the Americas predated the Maya and was possibly the invention of the Olmecs. [13] Many of the earliest Long Count dates were found within the Olmec heartland, although the Olmec civilization ended by the 4th century BC, several centuries before the earliest known Long Count dates. This could be interpreted in different ways. Some folks have made a link between this statement and the emission reporting requirements which uses GWP-100 to convert different gases to a CO2-equivalent to suggest that we should be aiming for net-zero emissions of CO2-e. However this does not have any particular geophysical significance since it could be associated with an increasing, decreasing or stable temperature depending entirely on what is happening to CH4, N2O and CFCs. The Arabic-language inheritance of science was largely Greek, [52] followed by Hindu influences. [53] In 773, at Al-Mansur's behest, translations were made of many ancient treatises including Greek, Roman, Indian, and others.

The Conference of the Parties] also recognizes that limiting global warming to 1.5 °C requires rapid, deep and sustained reductions in global greenhouse gas emissions, including reducing global carbon dioxide emissions by 45 per cent by 2030 relative to the 2010 level and to net zero around mid-century, as well as deep reductions in other greenhouse gases; Glasgow Pact final text, section 17 A commitment can be a catalyst for all kinds of positive changes, even if we do not know when we start exactly how we will reach our destination. However, given the scale of denial and deception around climate breakdown, we also need to be careful in our use of language.

Over the years, you have seen how easily it is for climate scientists to be misquoted and misinterpreted. Cue denialists quoting the post above as they pivot to greenwashing instead of frank denialism. SSP1-1.9 (the scenario that achieves a 50% chance of keeping global temperature increase below +1.5ºC) required 200Gt(C) net negative anthropogenic emissions, that being 730Gt(CO2), roughly half through the period 2050-2100 and the remaining half through 2100-50. An in addition to that net requirement is the sequestering of enough CO2 to balance any “above scenario” emissions to achieve the projected net emissions, positive pre-2050 and and negative post-2050.

Addition: x + 0 = 0 + x = x. That is, 0 is an identity element (or neutral element) with respect to addition. Bravely challenging the Establishment consensus ... forensically argued' - Mail on SundayThe British government has embarked on an ambitious and legally-binding climate change target: reduce the country's greenhouse gas emissions to Net Zero by 2050.

During the approval session for the IPCC AR6 Summary for Policy Makers, this was one of the persistent issues. Wherever the authors had made a reference to net-zero CO2 emissions, the Saudis (and sometimes China) tried to amend it to say net-zero greenhouse gases instead. The authors and many other countries took pains to explain that these were not commensurate statements, and the SPM text ended up making it clear that net-zero as a concept only applied to CO2.

Estimates of the amount of land required are as high as 3000 million hectares – twice the total amount of land currently under cultivation globally.

In the Chandah-sutra of Pingala, dating perhaps the third or second century BC, [ ...] Pingala's use of a zero symbol [śūnya] as a marker seems to be the first known explicit reference to zero. ... In the Chandah-sutra of Pingala, dating perhaps the third or second century BC, there are five questions concerning the possible meters for any value "n". [ ...] The answer is (2) 7 = 128, as expected, but instead of seven doublings, the process (explained by the sutra) required only three doublings and two squarings – a handy time saver where "n" is large. Pingala's use of a zero symbol as a marker seems to be the first known explicit reference to zero

In Formula One, if the reigning World Champion no longer competes in Formula One in the year following their victory in the title race, 0 is given to one of the drivers of the team that the reigning champion won the title with. This happened in 1993 and 1994, with Damon Hill driving car 0, due to the reigning World Champion ( Nigel Mansell and Alain Prost respectively) not competing in the championship. The British government has embarked on an ambitious and legally-binding climate change target: reduce the country’s greenhouse gas emissions to Net Zero by 2050. The Net Zero policy was subject to almost no parliamentary or public scrutiny, and is universally approved by our political class. But what will its consequences be?

Roulette wheels usually feature a "0" space (and sometimes also a "00" space), whose presence is ignored when calculating payoffs (thereby allowing the house to win in the long run). And that’s the point of Forum: to publish the books that rationally challenge groupthink, to ensure that important contributors to the key debates of our time who have unfashionable views aren’t closed down. I think that we will undoubtedly be doing that by publishing Ross’s excellent book. China This is a depiction of zero expressed in Chinese counting rods, based on the example provided by A History of Mathematics. An empty space is used to represent zero. [27] It is really not that hard to imagine a world with 100 simultaneous incidences of record breaking massive PNW heatwaves followed by wild fires, towns being burn to the ground and then followed a few weeks later destructive winds rainfall and flooding wiping out Billions of infrastructure and a whole season of agricultural crops and tens of thousands of head of cattle, sheep or pigs and poultry.
