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.

As climate change tightens its grip, the effects are being felt across the planet. The global ocean plays a key role and has so far soaked up most of the carbon dioxide and excess heat human activities have produced. But it is also vulnerable. Already some significant changes are underway, and the climate disruption

Indian disaster response teams evacuated millions of people from Odisha and West Bengal well in advance of Amphan (NDRF)
[By Hannah Cloke]
On May 18, a massive tropical cyclone with sustained winds of nearly 150 miles per hour was barrelling across the Bay of Bengal towards the low-lying coasts of East India and Bangladesh. This supercyclonic storm Amphan (from the Thai word meaning “sky” and pronounced “um-pun”) was the biggest in the Bay of Bengal since the 1999 Odisha cyclone, which killed 15,000 people.
A few days earlier, when it was just a plain old storm, Amphan had swept through Sri Lanka, killing several people in heavy rain, floods and winds. It would go on to
