Cyanobacteria (blue-green algae) bloom on Lake Erie (United States) in 2009. These kinds of algae can cause harmful algal bloom. A harmful algal bloom (HAB), or excessive algae growth, is an algal bloom that causes negative impacts to other organisms by production of natural algae-produced toxins, water deoxygenation, mechanical damage to other organisms, or by other means.
Microcystins cannot be broken down by standard proteases like pepsin, trypsin, collagenase, and chymotrypsin due to their cyclic chemical nature. [30] They are hepatotoxic , i.e., able to cause serious damage to the liver .
Many cases of anatoxin-a related animal deaths have occurred due to ingestion of detached benthic cyanobacterial mats that have washed ashore. [7] Anatoxin-a producing cyanobacteria have also been found in soils and aquatic plants. Anatoxin-a sorbs well to negatively charged sites in clay-like, organic-rich soils and weakly to sandy soils.
Global warming may not just melt the polar icecaps and create a snowpocalypse previously only seen in 'The Day After Tomorrow.'
Severe weather is one type of extreme weather, which includes unexpected, unusual, severe, or unseasonal weather and is by definition rare for that location or time of the year.

However, this unique phenomenon shows how birds, master migrators, can adapt to various weather conditions. The Sunshine State is home to some 1.3 million alligators, the most in the country.
The honey packets discourse online raises an important question: Why do some young men feel a need to use honey packets in the first place, assuming they don't have a sexual health issue? "These ...
Species that rely on cold weather conditions such as gyrfalcons, and snowy owls that prey on lemmings that use the cold winter to their advantage may be negatively affected. [24] [25] Climate change is also leading to a mismatch between the snow camouflage of arctic animals such as snowshoe hares with the increasingly snow-free landscape. [26]
