Global temperatures could reach the Paris Accords threshold soon

The World Meteorological Organization (WMO) has predicted that global temperatures may reach the threshold established in the Paris Climate Accords at least once within the next five years, according to a new forecast.

Countries in the 2015 Paris Agreement are working to limit the global temperature rise to 1.5 degrees Celsius (2.7 degrees Fahrenheit) above pre-industrial levels. The WMO says there’s a 20% chance at least one year between 2020 and 2024 could hit that marker. The warmest years on record have occurred since 2015, and 2020 may continue that trend.

While the forecast is worrisome, researchers will be watching to see if the global temperature reaches — and stays above — that 1.5 degree Celsius mark. The temperatures could naturally fluctuate year to year.

There is “a very small chance – just 3% – of the five-year average exceeding” that Paris Agreement threshold, Professor Richard Betts, a climate scientist at the U.K.’s Met Office, wrote on CarbonBrief. “This is a reminder of rising temperatures, but it would not mean that the long-term Paris goal to limit warming to 1.5C will have been breached,” he added on Twitter.

The forecast models don’t include recent declines in emissions due to COVID-19, but the WMO said short-term drops aren’t significant enough to affect an overall change in the global temperature. As countries have lifted restrictions, the emissions have rebounded.

The effects of the temperature increase wouldn’t be felt immediately, but the same would be true of halting it at 1.5 degrees Celsius, according to Betts. Some coastal areas could still experience more flooding, for example. “This all emphasizes how vital it is to stop the warming,” he wrote.

A massive data breach has left Intel scrambling for solutions
A render of an Intel Core HX chip.

A security breach in March robbed MSI of up to 1.5TB of sensitive data. However, MSI is not the only company impacted.

As a result of the breach, Intel is now investigating a major leak of Intel Boot Guard keys. The extent of the damage is still unclear, but the worst-case scenario is that the security feature is now useless on compromised devices -- and that's a pretty lengthy list.

Please let these rumors about Quick Resume for PC be true
The SoC inside the Xbox Series X.

Quick Resume is a beloved Xbox Series X feature, but despite a lot of overlap between Xbox and PC, Microsoft still hasn't been able to bring it to Windows.

However, it seems that gamers don't need to give up on it just yet. A recent comment made by Roanne Sones, head of Xbox devices, gave us a glimmer of hope -- but Quick Resume might be harder to achieve than it seems.
