Brazil"s catastrophic weather spawns spate of conspiracy theories
The climate catastrophe that has struck southern Brazil, killing more than a hundred people and displacing nearly two million, has also spawned a spate of bizarre conspiracy theories, some involving jets' vapor trails and weather antennas in faraway.....»»
Weaker ocean currents lead to decline in nutrients for North Atlantic ocean life during prehistoric climate change
Researchers at Georgia Institute of Technology have finished investigating how the prehistoric weakening of a major ocean current led to a decline in ocean nutrients and negative impacts on North Atlantic ocean life. The results support predictions a.....»»
Fresh rains pound Brazil"s flood-hit south as evacuations double
The skies opened once again Friday in southern Brazil, offering little respite for those whose homes have been swallowed by floodwaters, while the number of people forced to evacuate doubled in 24 hours......»»
