ON Earth Day April 22, this year, US President Joe Biden hosted a summit of world leaders to address climate change, something he had promised he would do during his presidential campaign, to once again establish US leadership on this vital global issue that former US President Trump had abandoned four years ago. The summit was attended by 40 countries including most developed countries and other nations with large national emissions such as China, the world’s largest emitter, Russia, India, and Brazil.

THE whole country is reeling under the brutal second wave of the Covid-19 pandemic, breaking world records for daily cases. The health infrastructure has collapsed and vital medical supplies such as oxygen are nearing exhaustion. With hospital beds and ICUs full, and no oxygen even leading to several tragic deaths, many hospitals have stopped admissions or have discharged patients. Thousands of people have been running from pillar to post for oxygen cylinders at least for use at home. Covid patients are helpless and literally gasping for breath.

WITH an eighth of the world’s population, the rich countries – the US, Canada, UK and the EU – have received more than 50 per cent of the world’s vaccine doses. The US alone has received 147 million vaccine jabs (see Table 1). This is more than 14 times what the entire continent of Africa – with four times the population of the US – has received. And if we do not count the vaccine doses that Morocco, truly an outlier in Africa, has received, the US has received 60 times the vaccine doses that Africa has!

TWO major hacks – SolarWind and Microsoft Exchange server hacks – have affected a whole range of computer systems. Both are supply-chain hacks, meaning what appeared to be a routine software upgrade to a particular component in the system instead inserted malicious code. In the SolarWind hack, a backdoor in one such component was downloaded to systems of 18,000 organisations, including even the US treasury, commerce, homeland security, state department.

THE Texas grid failure impacted millions with no electricity and no heating in sub-zero temperatures for days. It has not only caused scores of deaths and injuries, but also economic havoc in the state. Even after two weeks of the blackouts, life is far from normal as the citizens deal with frozen and burst pipes, denying people access to safe water and causing extensive damages to the houses. More than 13 million Texans were asked to boil their water as municipal water supply services were damaged.
