The scientific evidence is now overwhelming: climate change is a serious global threat, and it demands an urgent global response. This Review has assessed a wide range of evidence on the impacts of climate change and on the economic costs, and has used a number of different techniques to assess costs and risks. From all of these perspectives, the evidence gathered by the Review leads to a simple conclusion: the benefits of strong and early action far outweigh the economic costs of not acting. Climate change will affect the basic elements of life for people around the world – access to water, food production, health, and the environment. Hundreds of millions of people could suffer hunger, water shortages and coastal flooding as the world warms. Using the results from formal economic models, the Review estimates that if we don't act, the overall costs and risks of climate change will be equivalent to losing at least 5% of global GDP each year, now and forever. If a wider range of risks and impacts is taken into account, the estimates of damage could rise to 20% of GDP or more. In contrast, the costs of action – reducing greenhouse gas emissions to avoid the worst impacts of climate change – can be limited to around 1% of ...

Comments COVID-19, invasive species, and the spread of persistent chemicals and plastics provide one form of evidence that we live on a planet with an interconnected biosphere. Dangers from one part of the planet find their way to other parts of the planet. Our oceans and atmosphere, along with ships and jet planes, transport pollutants around the globe. Last week for a few terrifying days, we saw additional evidence of our interconnected biosphere. Fires burning about 400 miles from New York City The argument about the causes of the fires is pointless. Yes, we’ve always had forest fires, but the oceans and atmosphere are warmer than before, and the relationship between the growth of fossil fuel use to the rise in temperature is irrefutable. Global warming stimulates drought and drier conditions in places that once had plenty of precipitation. This, in turn, increases the risk of forest fires. We’ve seen it on our west coast for several years, and now it’s come to our east coast. If it feels terrifying and dangerous, that’s because it is. The question becomes: What do we do? Our economy, political stability, and way of life depend on the massive use of fossil fuels. We must transition from those fuels and away from other technologies that generate greenhouse gasses as quickly as possible. We need a less damaging, renewable resource-based economy. In America, Europe, and parts of Asia, the process of transition to the circular economy has already started. We are fortunate b...

People evacuate from a wildfire north of Athens, Greece, on Friday. A climate-driven heat wave helped create conditions for the fire to burn out of control. Scientists warn that humans are running out of time to curb greenhouse gas emissions and avoid catastrophic global warming.

A climate-driven heat wave helped create conditions for the fire to burn out of control. Scientists warn that humans are running out of time to curb greenhouse gas emissions and avoid catastrophic global warming. Thodoris Nikolaou/AP Global climate change is accelerating and human-caused emissions of greenhouse gases are the overwhelming cause, according to The message to world leaders is more dire, and more unequivocal, than ever before. "It is indisputable that human activities are causing climate change," says Ko Barrett, the vice chair of the U.N. Intergovernmental Panel on Climate Change (IPCC) and the senior adviser for climate at the U.S. National Oceanic and Atmospheric Administration. "Each of the last four decades has been the warmest on record since preindustrial times." The authors — nearly 200 leading climate scientists — hope the report's findings will be front and center when world leaders meet for a major climate conference in November. The effects of that warming are obvious and deadly around the world. Human activities are causing extreme weath...

Fine air pollution particles or aerosols, also known as fine particulate matter or PM 2.5, are responsible for 6.4 million deaths every year, caused by diseases such as ischemic heart disease, stroke, lung cancer, chronic obstructive pulmonary disease, pneumonia, type 2 diabetes, and neonatal disorders. About 95% of these deaths occur in developing countries, where billions of people are exposed to outdoor and indoor concentrations of PM 2.5 that are multiple times higher than guidelines established by the World Health Organization. Global health crises such as the COVID-19 pandemic weaken the resilience of societies. Compounding this, exposure to air pollution is linked to 2.5 concentration is associated with a 16% increase in employment growth rate and a A World Bank reportestimated that the cost of the health damage caused by air pollution amounts to $8.1 trillion a year, equ...
