The Australian heat wave is getting so hot that Australia’s Bureau of Meteorology had to add new colors to its weather map. There are parts of Australia that have achieved temperatures above 122ºF (50ºC), temperatures which were off the scale until recently.

Gene-Expression Indicates How Coral Reefs Will Handle Climate Change

Gene-Expression-Indicates-How-Coral-Reefs-Will-Handle-Climate-Change

Scientists have discovered a pattern of gene activity, which allows some corals to survive in higher temperatures. This suggests a way to predict how different corals will react to warmer waters, which are expected to result from climate change over the coming decades.

Politics – The Single Most Important Factor in Limiting Global Warming

global-warming

A new analysis finds that swift action by politicians is the single most important factor in limiting global warming. The costs of delays outweigh any possible benefits of waiting for more scientific research into the mechanisms of climate change.

The Amazon Rainforest Could Be Drying Out

burning-peruvian-amazon

In the past few years, the Amazon rainforest in Peru’s Ucayali region has been hit by two severe droughts, one in 2005 and another in 2010. These dry spells could become more frequent as temperatures in the tropical North Atlantic Ocean continue to rise and as thousands of square kilometers of forest are burnt to make way for farming.

All Coral Reefs May be Dying by 2100

Coral Reefs Might Disappear By 2100

If current carbon dioxide emission trends continue, nearly every coral reef would be decimated by 2100, according to a new review of major climate models. The only way to maintain the current chemical environment in which reefs need to live, would be to deeply cut emissions worldwide.

Physical and chemical conditions in the oceans cause populations of algae to wax and wane in cycles. Harmful algae consist of only a few species of diatoms, dinoflagellates, and cyanobacteria. Researchers are wondering what the role of climate change is in the algal blooms that have been seen in the last years.

Northern exposure, aggressive snowmaking and hard manmade snow crystals are helping some of the bigger ski resorts deal with climate change, but smaller operations are under threat as the warmer winters will lead to less snow on the ground.

Data Shows 2010 Amazon Megadrought Caused Serious Devastation

Devastation Found in Amazon

A new study indicates that the megadrought that struck the Amazon in 2010 devastated millions of hectares of rainforest, shedding a new light over the debate over the effects of recent climatic events.
