Climate change is definitely a concern but at the same time, so is fearmongering bullshit peddled by the ill-informed media. These climate extremes are nothing new - October in 2011 was pushing 30 degrees and over 100 years ago, even the end of September's could often exceed 30. In the 1970's, the UK experienced 16 consecutive days over 30 degrees before having several periods of wank weather since. Our July was miserable here and almost like a nostalgic English summer.
These incidents are just more pronounced now thanks to social media, heavily-bankrolled researchers needing persistent funding spanning decades and hypocritical climate protesters who post persistent misinformation they don't understand or can't comprehend. Even the Greece wildfires which were exclusively blamed on climate change by the Western media were actually a result of collaborated arson attacks which were filmed and published online and eventually saw 79 people identified and arrested. There were similar cases in Canada and California and once the human-element was discovered, the stories were sent to the bottom of the pile and comment sections were locked. The recent Hawaii fires which were also jumped on as a result of climate turned out to be poorly maintained electrical equipment setting fire to vegetation. Winds in the area also helped propel the fire rapidly. Once this was confirmed, the media abandoned the story and articles were 'modified' to add a speculative angle.
There is also overwhelming evidence that counter-research is being supressed from public publication at a huge cost and even Sadiq Khan was listed as an instigator as he blocked a conclusive report that his ULEZ scheme was worthless to the environment. There is no doubt climate change exists but it is very hard to have a real understanding of the true projected impact because of all this absolute tripe being peddled. Countries need to be doing more to reduce pollution regardless though.
