A hotter and more humid world has made tropical cyclones like hurricanes and typhoons more extreme but not more deadly.
On Monday, a hurricane battered Nicaragua before moving across Central America, claiming at least 57 lives. The day before, on the other side of the world, one of the strongest storms to ever hit land struck the Philippines. Its house-ripping winds reached speeds of 310 km/h (195mph) — as fast as a Japanese bullet train — but only grazed the area around the capital, narrowly missing 14 million people.
The storms are yet another example of how extreme weather is becoming terrifyingly ordinary as the climate changes.
So many hurricanes formed in the Atlantic this season that the World Meteorological Organization exhausted its 21-name-strong alphabetical

The most ambitious Arctic research expedition ever undertaken has come to a successful end after spending more than a year researching climate change in the Arctic, Drifting with the ice, the Multidisciplinary Drifting Observatory for the Study of Arctic Climate (MOSAiC) endured the extreme cold, Arctic storms, a constantly changing floe – and the challenges posed by the coronavirus pandemic.
The research icebreaker Polarstern returned to its homeport in Bremerhaven, Germany, on 12 October with an unparalleled treasure trove of data, which an entire generation of climate researchers will focus on analysing, according to the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI), which coordinated the expedition.
The journey was record-breaking: never before had an icebreaker

The first launches of artificial satellites beginning with Sputnik on 4 October 1957 by the Soviet Union and with Explorer I by the United States of America on 2 January 1958 heralded a new era of Earth observation. A few years later, on 1 April 1960, the first meteorological satellite, TIROS–1, was launched, providing the first-ever pictures of the distribution of clouds, images previously undreamed of (Figure 1). Although the spacecraft operated only for 78 days, meteorologists worldwide were ecstatic over the pictures of Earth and its cloud cover.

Hurricane Hunters are monitoring this one very closely.
Hurricane Delta intensifying
The center of Hurricane Delta was located near latitude 24.4 North, longitude 93.1 West.
Delta is moving toward the northwest near 13 mph, and this motion with a reduction in forward speed is expected this afternoon. A turn toward the north is forecast to occur by late tonight, followed by a north-northeastward motion by Friday afternoon or Friday night.
On the forecast track, the center of Delta will move over the western Gulf of Mexico this afternoon, over the northwestern Gulf of Mexico on Friday, and then move inland within the hurricane warning area Friday afternoon or Friday night. Maximum sustained winds are near 105 mph with higher gusts.
