Scientists are urgently trying to determine why so much Antarctic sea ice is missing during winter, Andrew writes.Sea ice should be growing during the region's winter season, but that growth is lagging significantly. If it signals a new, lasting shift, the unprecedented anomaly could have drastic global consequences. The missing ice area is about equal to the combined areas of Texas, California, New Mexico, Arizona, Nevada, Utah and Colorado. If
Antarctica's sea ice cover starts off the coming melt season this way,
it could accelerate global sea level rise by allowing greater amounts of
unusually warm waters to reach increasingly fragile land-based ice.
Now that climate change has raised the Earth’s temperatures to the highest levels in recorded history, with projections showing that they will only climb further, new research shows the impact of heat on workers is spreading across the economy and lowering productivity. Extreme heat is regularly affecting workers beyond expected industries like agriculture and construction. Sizzling temperatures are causing problems for those who work in factories, warehouses and restaurants and also for employees of airlines and telecommunications firms, delivery services and energy companies. Even home health aides are running into trouble.

If we do not stop using fossil fuels very quickly we shall all roast and the economy will fall apart.
