この赤で丸しているところのinvolvedは受動態の分詞だと思うんですが、scientist はNOAAに関与しているという能動の関係だと思うので、involvingじゃないんですか？

Can you blame the scorching weather on climate change? Not really. Or at least not yet.

Scientists involved in NOAA's report thought that climate change did significantly increase the likelihood of last year's warm winter in the United Kingdom and heat wave in Texas, though their calculations are admittedly imperfect. Experts also determined 10 they could not show that global warming contributed to flooding in Thailand - the level of rainfall wasn't historically unusual.
