Are we ready to tackle the threats posed by climate change?

Climate change and human healthClimate change is happening, and as professionals, we must not underestimate or ignore it 1 .Global environmental change poses a serious risk to humanity 2 .The rise in greenhouse gas emissions has elevated global temperatures, instigated extreme weather events, and led to rising sea levels that can jeopardize food security and nutrition, promote the spread of infectious diseases, and displace communities, significantly impacting human health 3,4 .Global warming is leading to climate change, with potentially adverse effects on human health.In addition to global warming, certain air pollutants, including PM2.5, NO 2 , SO 2 , CO, and tropospheric O 3 , can result in various health issues for both humans and animals.The effects of climate change on human health can be categorized into four key areas: the impact of global warming on humans, deforestation and land degradation, changes in marine ecosystems, and disruptions to water supply systems 5 .A recent study has identified various climate-related factors, including extreme weather events (affecting temperatures and precipitation), air quality issues, allergens, food and water scarcity, and shifts in the spread of pathogens and vectors 6 .These factors can be related to health outcomes sensitive to climate, including diseases caused by vectors, cardiovascular diseases 7 , gastrointestinal disorders 8 , neurodegenerative disorders 9,10 , allergic reactions 11 , and kidney-related disorders 12 .
