Rainbows are often seen as signs of hope. And we are likely to see more of them due to global warming, according to a new study     1    (publish) in the journal Global Environmental Change.

    2     (gather)121,558 rainbow pictures from the internet taken between 2004 and 2019, the research team then used the    3     (photo) to form a database which allowed the researchers     4     (learn) the patterns of how rainbows occur.

Rainbows only appear with a suitable angle of the sun, rainfall and less clouds. Due to the emission of greenhouse gases, there will be more rainfall and less clouds,     5     can lead to more rainbows in the future.

The team also predicted that global rainbow     6     (occur) might increase by 4 to 5 percent by 2100.     7    , some places in the world may witness fewer rainbows. For example, the climate in tropical areas in Africa and South America may be     8     (dry) with less rainfall.

The researchers also called on more studies about how people’s lives can     9     (affect), apart from the changes     10    which we are already familiar. “Shifts in intangible (无形的)parts of our environment - such as sound and light - are part of these changes and deserve more attention from researchers,” the lead author of the study Kimberly Carlson said to Science X Network.

Little pool penguins are the world’s smallest penguin species. Hundreds of these little birds are washing up, dead, on New Zealand shores, shocking residents walking along the beaches and worrying experts about the implications of     1     so many deaths could mean. The abundant deaths     2     (lead) scientists and conservation experts to ask: How much is normal? And will it get worse? Who is to blame? Probably climate change is making it a lot worse for the penguins as sea surface temperature increases and marine heat waves and storms become     3     (frequent). As a consequence, less than a third of all chicks typically survive to adulthood,     4     (base) on studies in the South Island of New Zealand.
