We now know the power that political leaders can wield when the challenge demands it giving us the means to combat climate change.

In recent years, mountain communities in Chile have been facing longer and more intense dry spells thanks, in part, to rapidly shrinking glaciers in the Andes. This puts serious stress on local communities that rely on their fresh water.
But a team of Chilean climate experts have come up with a solution. In 2022, they will attempt to DIY their own glaciers, in hopes of supplying fresh water through the dry, summer months.
But some experts want more evidence.
A 1.5 million-year-old vertebra from an extinct human species unearthed in Israel suggests that ancient humans may have migrated from Africa in multiple waves, a new study finds.
Although modern humans, Homo sapiens, are now the only surviving members of the human family tree, other human species once roamed Earth. Prior work revealed that long before modern humans made their way out of Africa as early as about 270,000 years ago, now-extinct human species had already migrated from Africa to Eurasia by at least 1.8 million years ago, during the early parts of the Pleistocene (2.6 million to 11,700 years ago), the epoch that included the last ice age.
Machine learning can work wonders, but it’s only one tool among many.
Artificial intelligence is among the most poorly understood technologies of the modern era. To many, AI exists as both a tangible but ill-defined reality of the here and now and an unrealized dream of the future, a marvel of human ingenuity, as exciting as it is opaque.
It’s this indistinct picture of both what the technology is and what it can do that might engender a look of uncertainty on someone’s face when asked the question, “Can AI solve climate change?” “Well,” we think, “it must be able to do *something*,” while entirely unsure of just how algorithms are meant to pull us back from the ecological brink.

An international study involving researchers from CNRS and CEA as well as the company Kayrros reveals hundreds of major methane leaks linked to the global exploitation of oil and gas. Scientists show that their mitigation would lead to climatic and economic benefits amounting to billions of dollars for the main hydrocarbon producing countries. This work is published on February 4, 2022 in the journal Science.

A major contributor to climate change, methane (CH 4) has a warming potential over 100 years approximately 30 times greater than that of CO 2. A quarter of anthropogenic emissions of this greenhouse gas come from the global exploitation of coal, oil and natural gas, of which CH4 is the main component. In 2018, a study had already exposed, based on the case of the United States, the vast underestimation in official inventories of emissions related to the extraction and distribution of oil and gas. A discrepancy which could be explained by sporadic undeclared releases of large quantities of methane by operators in the sector.
Ben RayfieldWeather control tech exists, to some extent. EMP weapons exist. If there was a 477 mile long lightning, it was probably either due to the sun or is a weapon or a terraforming experiment.
