Assisted migration is a potential solution to changes in environments due to climate change that are faster than natural selection can adapt to. [107] [108] It has the potential to allow species that have poor natural dispersal abilities to avoid extinction. However it has also sparked debate over the possibility of the introduction of invasive ...
These breakthroughs, from industry, government, and everyday people, are protecting our planet. Experts explain what's new with electric cars, CO2 emissions, methane, and more.
Climate change can also be used more broadly to include changes to the climate that have happened throughout Earth's history. [32] Global warming—used as early as 1975 [33] —became the more popular term after NASA climate scientist James Hansen used it in his 1988 testimony in the U.S. Senate. [34] Since the 2000s, climate change has ...
The American Association for the Advancement of Science adopted an official statement on climate change in 2006: "The scientific evidence is clear: global climate change caused by human activities is occurring now, and it is a growing threat to society. ... The pace of change and the evidence of harm have increased markedly over the last five ...

In a study of more than 50,000 patients in the Mayo Clinic Health System https://bit.ly/37Btmhf, researchers found the effectiveness of Moderna's vaccine against infection had dropped to 76% in ...
A 2019 review of scientific papers found the consensus on the cause of climate change to be at 100%, [6] and a 2021 study concluded that over 99% of scientific papers agree on the human cause of climate change. [7] The small percentage of papers that disagreed with the consensus often contained errors or could not be replicated. [8]
Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations.
