Climate change is already affecting life on Earth, despite a global temperature increase of just 1°C, according to a new study published in the journal Science on Friday.Nearly every ecosystem on the planet is being altered, and plants and animals are being so affected that scientists may soon be forced to intervene to create \u0022human-assisted evolution,\u0022 the study, titled The Broad Footprint of Climate Change from Genes to Biomes to People, found.The researchers say 82 percent of \u0022core ecological processes\u0022 on land and sea have been affected by climate change in a way that had not been expected \u0022for decades.\u0022Co-author and professor John Pandolfi of the University of Queensland said, \u0022Temperature extremes are causing evolutionary adaption in many species, changing them genetically and physically. These responses include changes in tolerances to high temperatures, shifts in sex-ratios, reduced body size, and migration of species.\u0022\u0022Understanding the extent to which these goods and services have been impacted allows humans to plan and adapt to changing ecosystem conditions,\u0022 he said.Dr. James Watson, associate professor of planning and environmental management at UQ\u0026#039;s School of Geography, added, \u0022We are simply astonished at the level of change we observed which many of us in the scientific community did not expect to see for decades.\u0022The changes have manifested in some species shifting to higher or lower ground as the planet heats up, while others are becoming smaller, \u0022as a higher surface-area-to-body-mass ratio makes it easier to stay cool,\u0022 the Independent reported. The outlet wrote:For example, six species of woodland salamander in the Appalachian Mountains have undergone an average eight per cent reduction in body size over the past 50 years.Slightly smaller lizards might not sound like something to overly concern humans, but there is evidence this response is also affecting important sources of food.\u0022These multi-level biological impacts of climate change will affect humans. Increasing disease outbreaks, inconsistent crop yields, and reduced fisheries productivity all threaten our food security,\u0022 said co-author Dr. Tom Bridge.Average global temperatures have risen 1°C since the industrial era. The study states that this has \u0022already had broad and worrying impacts on natural systems, with accumulating consequences for people. Minimizing the impacts of climate change on core ecological processes must now be a key policy priority for all nations.\u0022The study called on governments to follow through on the promises made in the Paris climate agreement, which aims to keep global warming below a 1.5°C threshold—although an increasing amount of scientists are sounding the alarm that even those pledges may be too little, too late.\u0022Time is running out for a globally synchronized response to climate change that integrates adequate protection of biodiversity and ecosystem services,\u0022 the study continued.\u0022It is no longer sensible to consider this as a concern for the future—if we don\u0026#039;t act quickly to curb emissions it is likely that every ecosystem across Earth will fundamentally change in our lifetimes,\u0022 said Dr. Watson.
