It's nice when you get your #SpaceWeather forecasts right given all the uncertainties.
Three M class flares and counting. A partial halo CME was associated with the M4.4 flare originating from AR 14168. The CME has a moderate chance of Earth impact on 9 Aug with an estimated arrival speed of around 450 km/s. Severe space weather perturbations not expected.

To add context, the recent warming we see has been shown to be driven primarily by anthropogenic forcing. This understanding is based on analysis and scientific consensus. In the absence of major anthropogenic forcing (before the industrial revolution) or intrinsic geological.

No.
Solar Activity hits a GRAND MAXIMUM, so enormously high, it's not been seen at this level for 11,000 years. Could this have caused the Earth to warm up a bit?

A link to India's Astronomy Mega Science Vision is below. From the translational perspective, it was important for me to ensure space weather research for 1) the benefit of humanity and 2) protection of our space reliant technologies feature prominently.
